Detailed Description
In the present specification, the expressions "upper" and "lower" refer to upper and lower sides when the laminated glass for a vehicle is mounted on a vehicle. The "side" of the laminated glass for a vehicle means a portion connecting the upper side and the lower side. The "cross section" refers to a cut when the laminated glass for a vehicle is cut in the thickness direction or a side surface of the laminated glass for a vehicle. In addition, the side faces are not terms defining faces that include only side edges. In the present specification, "peripheral edge" means the outermost peripheral edge of the predetermined member, and "peripheral edge portion" means the vicinity of "peripheral edge". When the predetermined member has a hollowed-out portion, the "peripheral edge" is also referred to as an "outer edge" and may be distinguished from an "inner edge" which is a side of the hollowed-out portion.
In the present specification, "the same shape", "the same size" means that the human eyes see the same shape and the same size. The term "substantially" means that the same is seen by the human eye unless otherwise specified. Further, "to" representing the numerical range includes upper and lower limits.
The laminated glass for a vehicle according to the embodiment of the present invention is applicable to, for example, windshields, rear window glass, side window glass, sunroof glass, triangular window glass, and the like. The laminated glass for a vehicle is hereinafter also simply referred to as "laminated glass".
Several embodiments of the present invention will be described below with reference to the drawings. In the drawings, the curved shape is also indicated as a planar shape in order to make the constituent elements easily visible, and the dimensional ratios of the constituent elements are different.
(embodiment 1)
Embodiment 1 of the present invention will be described below with reference to fig. 1 to 3. Fig. 1 is a plan view of a laminated glass for a vehicle according to embodiment 1 of the present invention, and is also a plan view of embodiment 2 and embodiment 3 of the present invention described later.
The laminated glass 100 for a vehicle according to the present embodiment includes a 1 st glass plate 10 and a 2 nd glass plate 18 having the same main surface shape, and an interlayer 20 disposed therebetween. Then, the 1 st glass plate 10, the interlayer 20, and the 2 nd glass plate 18 are laminated in this order. The center axis (not shown) of the vehicle laminated glass 100 is a virtual line passing through the center of gravity G of the vehicle laminated glass 100 in the thickness direction.
As shown in fig. 1, the laminated glass 100 for a vehicle has a substantially trapezoidal shape in plan view, but is not limited thereto. The vehicle laminated glass 100 may be, for example, substantially triangular or substantially rectangular in plan view, depending on the location to be mounted on the vehicle.
In addition, looking down on the vehicle laminated glass 100 or looking down on the 1 st glass plate 10 means that the vehicle laminated glass 100 is placed on a horizontal plane, and the 1 st glass plate 10 is made to face upward, and the horizontal plane is viewed from vertically above. The term "view in the cross-sectional view" means that a predetermined cross-section of the laminated glass for a vehicle is viewed from the vertical direction. Further, the side view means that a predetermined side surface (for example, a side surface including the power feeding side 10 s) of the laminated glass for a vehicle is viewed from the vertical direction.
At least a part of the cross section of the laminated glass 100 for a vehicle in the up-down direction may be substantially wedge-shaped, the thickness of which gradually decreases. A laminated glass having a cross-sectional shape in the vertical direction, which is a wedge shape at least a part of which is thickened from the lower side to the upper side, is suitable for functioning as a Head Up Display (HUD), and particularly suitable for use in a windshield. In order to provide the laminated glass 100 for a vehicle with such a cross-sectional shape, at least a part of the cross-section in the up-down direction of at least one of the 1 st glass plate 10, the 2 nd glass plate 18, and the interlayer 20 may be substantially wedge-shaped.
As shown in fig. 1, a laminated glass 100 for a vehicle according to the present embodiment includes a 1 st functional member 14 and a 2 nd functional member 15 in an interlayer film 20. The 1 st functional member 14 and the 2 nd functional member 15 do not overlap when the 1 st glass plate 10 is viewed from above. That is, the 1 st functional member 14 is separated from the 2 nd functional member 15 when the 1 st glass plate 10 is viewed from above. Further, the peripheral edges of the 2 functional members 14, 15 are each located further inside than the peripheral edge of the 1 st glass plate 10. Herein, "inside" means a central axis direction passing through the center of gravity G of the laminated glass 100 for a vehicle when viewed from the periphery of the predetermined member (here, the 1 st glass plate 10). In contrast, "outside" means the peripheral direction of the predetermined member (here, the 1 st glass plate 10) when viewed from the central axis passing through the center of gravity G of the laminated glass 100 for a vehicle.
Hereinafter, the 1 st power supply 16 and the 2 nd power supply 17 will also be simply referred to as "power supplies". The functional member side end of the power supply body may be directly electrically connected to the functional member, or may be electrically connected via a transparent conductive film or a foil-shaped conductor called a bus bar. The connection method may be any known method.
The 1 st power supply body 16 and the 2 nd power supply body 17 are flexible band-shaped connection members each having at least 2 foil-shaped conductors having different electric potentials when the functional member is operated, and each being covered with an insulating material. Specifically, the 1 st power supply 16 has foil-like conductors 36 and 36 'inside the insulating material, and the 2 nd power supply 17 has foil-like conductors 37 and 37' inside the insulating material. The foil conductors 36 and 36' of the 1 st power supply body 16 are arranged apart within the insulating material, and they are arranged in such a manner that no electrical short circuit occurs. The foil conductors 37 and 37' of the 2 nd power supply 17 are also arranged apart in the insulating material, and they are also arranged in such a way that no electrical short circuit occurs.
The foil conductor 36 'is disposed on the 2 nd power supply 17 side, and the foil conductor 37' is disposed on the 1 st power supply 16 side. Thus, the foil-like conductor 36 'and the foil-like conductor 37' are the closest conductors among the 1 st power supply 16 and the 2 nd power supply 17. The foil conductors 36, 36', 37' are each covered with an insulating material except for the end portions (the contact points with the functional members). Regarding the foil-like conductor, the portion indicated by the dash-dot line in fig. 1 indicates the approximate shape of the portion covered with the insulating material, and the portion indicated by the dash-dot line indicates the approximate shape of the portion not covered with the insulating material.
Further, according to the laminated glass 100 for a vehicle of the present embodiment, the 1 st glass plate 10 and the 2 nd glass plate 18 may be configured without a notch. In the case where the 1 st glass plate 10 and the 2 nd glass plate 18 have a structure without a notch, at least the step of cutting the glass plates and the step of sealing the notch are not necessary. However, the laminated glass 100 for a vehicle according to the present embodiment may be provided with a notch. The "notch" refers to a recess provided in a part of the peripheral edge of the 1 st glass plate 10 or the 2 nd glass plate 18 when the laminated glass 100 for a vehicle is viewed from above. The notch is also referred to as a region where the 1 st glass plate 10 and the 2 nd glass plate 18 do not overlap and are adjacent to a part of the peripheral edge of the 1 st glass plate 10 when the 1 st glass plate 10 is viewed from above.
The 1 st power supply 16 and the 2 nd power supply 17 are typically flexible materials. When these power supplies overlap each other in a plan view of the 1 st glass plate 10, if the coating portion is broken or the like after the vehicle laminated glass 100 is assembled to the vehicle, there is a possibility that the conductor portion of one power supply contacts the conductor portion of the other power supply to cause a short circuit. Therefore, the 1 st power supply body 16 and the 2 nd power supply body 17 do not overlap in the plane of the 1 st glass plate 10 when the 1 st glass plate 10 is viewed from above, and short circuit can be prevented. In addition, when the 1 st glass plate 10 is viewed in plan, the 1 st power supply 16 and the 2 nd power supply 17 preferably do not overlap with each other even outside the 1 st glass plate 10.
In addition, when the 1 st glass plate 10 is viewed from above, the 1 st power supply 16 and the 2 nd power supply 17 intersect only one side (hereinafter also referred to as a power supply side) of the 1 st glass plate 10. Thus, wiring in the vehicle body frame extending outside the vehicle laminated glass 100 can be simplified, and handling can be facilitated. The position of the power supply side is not particularly limited, and may be, for example, the upper side or the lower side of the 1 st glass plate 10, and is preferably the lower side (power supply side 10 s) close to the power supply mounted on the vehicle.
In the laminated glass 100 for a vehicle shown in fig. 1, the 1 st power supply body 16 and the 2 nd power supply body 17 are arranged substantially in parallel from the power supply side 10s as the lower side to the 1 st functional member 14 and the 2 nd functional member 15. However, the 1 st power supply body 16 and the 2 nd power supply body 17 may not be substantially parallel to each other from the power supply side 10s to each functional member. For example, in fig. 1, the 1 st power supply body 16 may be electrically connected to the 1 st functional member 14 via the vicinity of the side edge and/or the vicinity of the upper edge inside the vehicle laminated glass 100. The 2 nd power supply 17 may be electrically connected to the 2 nd functional member 15 via the vicinity of the side edge and/or the vicinity of the upper edge inside the vehicle laminated glass 100.
The substantially parallel direction means that a distance d between the 1 st power supply body 16 and the 2 nd power supply body 17 (hereinafter, also simply referred to as "inter-power-supply-body distance") is set to be equal to the power supply side 10s 1 A distance change of + -20% is allowed. Distance d between power supplies 1 Refers to the distance from the side end of the 2 nd power supply 17 of the foil conductor 36 'to the side end of the 1 st power supply 16 of the foil conductor 37', measured along the power supply edge 10 s.
Distance d between power supplies 1 Preferably 100mm or less. If the distance d between the power supplies 1 When the distance is 100mm or less, it is easy to bundle cables connecting power supplies to a power supply mounted on a vehicle, and the distance from a branch point of the bundled cables to each power supply becomes short, so that the cables are not easy to shake even if the cables are not fixed to a vehicle body frame. Distance d between power supplies 1 More preferably 50mm or less, and still more preferably 35mm or less. In this way, when these power supplies are exposed to the outside of the vehicle laminated glass 100 from the single power supply side 10s, the bundling easiness of the cables and the effect of suppressing the vibration of the cables become remarkable when the 1 st glass plate 10 is viewed from above, as compared with the arrangement in which the 1 st power supply 16 and the 2 nd power supply 17 are exposed to the outside of the vehicle laminated glass 100 from different sides.
In addition, with respect to the power feeding side 10s, in order to protect the 1 st functional member 14 (2 nd functional member 15) from physical impact, moisture, or the like, a distance d in the plane direction (Y-axis direction) from the power feeding side 10s to the peripheral edge of the 1 st functional member 14 (2 nd functional member 15) 2 More than 0mm, preferably 5mm or more, and more preferably 10mm or more. Thus, the peripheral edges of the 1 st functional member 14 and the 2 nd functional member 15 are preferably spaced apart from the peripheral edge of the 1 st glass plate by 5mm or more, more preferably by 20mm or more.
As shown in fig. 1, the vehicle laminated glass 100 may include a band-shaped light shielding portion 50 at a peripheral edge portion. The light shielding portion 50 can conceal all or part of the peripheral edges of the functional members 14, 15, the power supplies 16, 17, parts attached to the vehicle frame or the like, residual air bubbles or the like described later.
Fig. 2 shows an X of fig. 1 of a laminated glass 100 for a vehicle 1 -X 2 A cross-sectional view taken in the negative Y-axis direction when cut in the XZ plane (hereinafter also referred to as "X 1 -X 2 Cross-sectional view "). In fig. 2, a laminated glass 100 for a vehicle is laminated in the order of a 1 st glass plate 10, an interlayer film 20, and a 2 nd glass plate 18. The interlayer 20 is laminated in the order of the 1 st interlayer 11, the 1 st adjustment interlayer 21, and the 2 nd interlayer 12 from the 1 st glass plate 10 side. Further, the 1 st functional member 14 and the 2 nd functional member 15 are each sandwiched between the 1 st intermediate film 11 and the 2 nd intermediate film 12, and exist on substantially the same plane. In fig. 2, the 1 st glass plate 10 has a 1 st main surface 10a located on the opposite side of the 1 st interlayer 11 side and a 2 nd main surface 10b located on the 1 st interlayer 11 side. The 2 nd glass plate 18 has a 3 rd main surface 18c located on the 2 nd interlayer 12 side and a 4 th main surface 18d located on the opposite side from the 2 nd interlayer 12 side.
However, in the laminated glass 100 for a vehicle, for example, when the members are laminated in the manufacturing process, unnecessary bubbles (hereinafter, also referred to as "bubble residues") may be generated in the laminated glass for a vehicle due to a difference in level or the like generated at the peripheral edge of the functional member or the power supply body. In addition, since the intermediate film 20 is deformed in the manufacturing process, bubble residue may occur in the vicinity of the level difference.
The air bubbles remaining in the laminated glass 100 for a vehicle may lower the adhesion force between the 1 st glass plate 10 and the 2 nd glass plate 18 via the interlayer film 20, and may cause breakage even more easily due to an impact from the outside. Therefore, in the laminated glass 100 for a vehicle, the area of the bubble remaining portion is preferably small when the 1 st glass plate 10 is viewed in plan. In addition, in the case where the laminated glass 100 is mounted as a windshield on a vehicle, if the driver sees that bubbles remain, driving may be hindered. Therefore, at least in the laminated glass 100 for a vehicle, it is preferable that the bubble remaining in the opening portion described later is inconspicuous. Therefore, in order to eliminate the height difference (gap) at the peripheral edge of the functional member and reduce the bubble residue, the laminated glass 100 of the present embodiment includes the 1 st adjustment interlayer 21 between the 1 st interlayer 11 and the 2 nd interlayer 12.
That is, in the case of the laminated glass 100 in plan view, the inner edge shape of the 1 st adjustment intermediate film 21 is substantially the same as the peripheral edge shapes of the 1 st functional member 14 and the 2 nd functional member 15. The 1 st functional member 14 and the 2 nd functional member 15 are located in the hollow portion on the inner side than the outer edge of the 1 st adjustment intermediate film 21.
However, the 1 st functional member 14 and the 2 nd functional member 15 are not necessarily located in 2 cutouts of the 1 st adjustment intermediate film 21, which are independent of each other, but a plurality of functional members may be located in 1 (large) cutouts, which are independent of each other. Further, at least a part of the peripheral edges of the 1 st functional member 14 and the 2 nd functional member 15 may meet the inner edge of the 1 st adjustment intermediate film 21.
In this way, at least a part of the peripheral edges of the 1 st functional member 14 and the 2 nd functional member 15 is in contact with the inner edge of the 1 st adjustment intermediate film 21, so that gaps are less likely to occur in the peripheral edge portions of the functional members at the contact portions when the 1 st glass plate 10 and the 2 nd glass plate 18 are laminated, and adhesion is more likely to occur via the intermediate film 20. From the viewpoint of reducing the bubble residue, the ratio of the length of the peripheral edges of the 1 st functional member 14 and the 2 nd functional member 15 to the length of the inner edge of the 1 st adjustment intermediate film 21 is preferably 50% or more, more preferably 70% or more, still more preferably 90% or more, and particularly preferably 100%, respectively.
To reduce bubble residue, inter-power-supply distance d 1 Preferably 50mm or less, more preferably 45mm or less, further preferably 35mm or less, particularly preferably 25mm or less, and most preferably 15mm or less. In addition, inter-power-supply-body distance d 1 For example, it is preferably 2mm or more. If the distance d between the power supplies 1 When the thickness is 2mm or more, the power supplies are less likely to overlap each other even when the positional deviation of the 1 st functional member 14 and the 2 nd functional member 15 at the time of lamination and the mounting accuracy of the power supplies are taken into consideration. Therefore, the bubble residue is easily reduced, and breakage of the laminated glass 100 for a vehicle at the time of press bonding and after distribution is easily reduced. Distance d between power supplies 1 The diameter may be 3mm or more, 4mm or more, or 5mm or more. On the other hand, a distance d from the power feeding side 10s to the peripheral edge of the 1 st functional member (2 nd functional member) 2 Preferably 65mm or less, more preferably 60mm or less, further preferably 40mm or less, particularly preferably 30mm or less, and most preferably 20mm or less.
In the high-temperature and high-pressure environment in the manufacturing process of the laminated glass 100 for a vehicle, the laminated interlayer film 20 flows. Distance d 2 The smaller the air bubbles generated in the vehicle laminated glass 100, the higher the probability of reaching the power feeding body side 10s and disappearing, and the less the air bubbles remain.
Fig. 3 is a side view of the laminated glass 100 for a vehicle including the power feeding side 10 s. In a side view of the laminated glass 100 of the present embodiment, the 1 st power supply 16 is sandwiched between the 1 st intermediate film 11 and the 1 st adjustment intermediate film 21, and the 2 nd power supply 17 is sandwiched between the 2 nd intermediate film 12 and the 1 st adjustment intermediate film 21. In this way, the power supply members are sandwiched by the intermediate film 20, and thus the vehicle laminated glass 100 can firmly hold the power supply members.
In the laminated glass 100 for a vehicle of the present embodiment shown in fig. 3, the 1 st power supply 16 is disposed on one principal surface side of the 1 st adjustment intermediate film 21, and the 2 nd power supply 17 is disposed on the other principal surface (the opposite principal surface of the one surface) side of the 1 st adjustment intermediate film 21. As described above, in the laminated glass 100 for a vehicle according to the present embodiment, the 1 st power supply body 16 and the 2 nd power supply body 17 are disposed on different principal surfaces.
That is, the 1 st functional member 14 and the 2 nd functional member 15 are present on substantially the same plane, but the distance from the main surface of one glass plate (for example, the 2 nd main surface 10b of the 1 st glass plate 10) to the 1 st power supply 16 is different from the distance from the main surface (10 b) of the glass plate to the 2 nd power supply 17. In the high-temperature and high-pressure environment in the manufacturing process of the laminated glass 100 for a vehicle, the laminated interlayer film 20 flows. Thus, the respective intermediate films constituting the intermediate film 20 are bonded to each other, so that the interface area is reduced, and an effect of achieving uniform thickness is produced. Therefore, by making the distance from the main surface of one glass plate to the 1 st power supply 16 different from the distance from the main surface of the glass plate to the 2 nd power supply 17, the interlayer film 20 is made to flow actively, and thus the corners between the glass plates are more easily filled. As a result, bubble residue is less likely to occur, and the adhesion force between the glass plate and the interlayer film 20 is also improved.

Fig. 4 is a side view of a laminated glass 200 for a vehicle according to embodiment 2 of the present invention, including a power feeding side 10 s. In this embodiment, the differences from the vehicle laminated glass 100 of embodiment 1 will be described, and the description of embodiment 1 will be otherwise cited.
In the present embodiment, as shown in fig. 4, the 1 st power supply body 16 and the 2 nd power supply body 17 are disposed on the same surface side of the 1 st adjustment intermediate film 21. That is, in the laminated glass 100 for a vehicle, the distance from one principal surface of the glass plate (for example, the 2 nd principal surface 10b of the 1 st glass plate 10) to the 1 st power supply body 16 is substantially the same as the distance from the principal surface (10 b) of the glass plate to the 2 nd power supply body 17. In this case, the intermediate film 20 includes the auxiliary intermediate film 25 at least at a portion between the 1 st power supply body 16 and the 2 nd power supply body 17 (in the X axis direction), whereby the bubble residue can be reduced. Further, the provision of the auxiliary intermediate film 25 can reduce stress applied to the glass during press-bonding. This can reduce the breakage caused by the primary stress at the time of press-bonding or the breakage caused by the residual stress in the market.
The auxiliary intermediate film 25 may be composed of at least 1 of the same materials as the 1 st intermediate film 11, the 2 nd intermediate film 12, and the 1 st adjustment intermediate film 21. The auxiliary intermediate film 25 may extend in the Y-axis direction from between the 1 st power supply body 16 and the 2 nd power supply body 17 to between the 1 st functional member 14 and the 2 nd functional member 15, for example. In this case, if the auxiliary intermediate film 25 is disposed at least in a part between the 1 st functional member 14 and the 2 nd functional member 15 (in the X-axis direction), it is preferable from the viewpoint of the effect of reducing the residual air bubbles, and more preferable is disposed in all of them. Further, the auxiliary intermediate film 25, the 1 st intermediate film 11, the 2 nd intermediate film, and the 1 st adjustment intermediate film 21 are more preferably each composed of the same material.
(embodiment 3)
Fig. 5 is a side view of a laminated glass 300 for a vehicle according to embodiment 3 of the present invention, including a power feeding edge 10 s. In fig. 5, the dashed lines show the general shapes of the 1 st functional member 14 and the 2 nd functional member 15 to clarify the arrangement of the intermediate film 20 and the functional members 14, 15 and the power supplies 16, 17.
In the present embodiment, the laminated glass 300 for a vehicle has an intermediate film 20, and the intermediate film 20 is laminated in the order of the 1 st intermediate film 11, the 3 rd intermediate film 13, and the 2 nd intermediate film 12. Further, the 3 rd intermediate film 13 is disposed between the 1 st functional member 14 and the 2 nd functional member 15 (in the Z direction). The 1 st functional member 14 and the 1 st power supply body 16 are sandwiched between the 1 st intermediate film 11 and the 3 rd intermediate film 13, and the 2 nd functional member 14 and the 2 nd power supply body 17 are sandwiched between the 2 nd intermediate film 12 and the 3 rd intermediate film 13.
In this way, in the present embodiment, the 1 st functional member 14 and the 1 st power supply 16, and the 2 nd functional member 15 and the 2 nd power supply 17 are separated by the 3 rd intermediate film 13. Thus, the 1 st functional member 14 and the 2 nd functional member 15 do not exist on the same plane. Also, the 1 st power supply body 16 and the 2 nd power supply body 17 do not exist on the same plane.
Therefore, the distance from the 2 nd main surface 10b of the 1 st glass plate 10 to the 1 st power supply 16 is different from the distance from the 2 nd main surface 10b of the 1 st glass plate 10 to the 2 nd power supply 17. Therefore, the interlayer 20 actively flows in a high-temperature and high-pressure environment in the manufacturing process of the laminated glass 300 for a vehicle, and thus, each corner between glass sheets is easily filled. As a result, bubble residue is less likely to occur, and adhesion between the glass plate and the interlayer film is improved.
The vehicle laminated glass 300 according to the present embodiment may have a 1 st adjustment interlayer (not shown) between the 1 st interlayer 11 and the 3 rd interlayer 13. In this case, the 1 st adjustment interlayer is different from embodiment 1 in that it has a hollowed-out portion having substantially the same shape as the outer edge shape of the 1 st functional member 14, and does not have a hollowed-out portion having substantially the same shape as the outer edge shape of the 2 nd functional member 15 when the laminated glass 100 is viewed from above.
A 2 nd adjustment intermediate film (not shown) may be provided between the 2 nd intermediate film 11 and the 3 rd intermediate film 13. At this time, the outer edge shape of the 2 nd adjustment intermediate film (not shown) is substantially the same as the 1 st glass plate 10, and has a hollowed-out portion having substantially the same shape as the outer edge shape of the 2 nd functional member 15. Then, the 2 nd functional member 15 is located in the hollowed portion on the inner side than the outer edge of the 2 nd adjustment intermediate film. These adjustment intermediate films are effective in improving the adhesion between the 1 st glass plate 10 and the 2 nd glass plate 18 at the peripheral edge portions of the functional members and reducing the residual bubbles. Further, the provision of these auxiliary intermediate films can reduce stress applied to the glass during press-bonding. This can reduce the breakage caused by the primary stress at the time of press-bonding or the breakage caused by the residual stress in the market.

Embodiment 6 of the present invention will be described below with reference to fig. 4 to 8. Fig. 6 is a plan view of the laminated glass for a vehicle according to embodiment 4, and is also a plan view of the laminated glass for a vehicle according to embodiment 5 described later. In this embodiment, the differences from the vehicle laminated glass 100 of embodiment 1 are similarly described, and the description of embodiment 1 is otherwise cited.
In the laminated glass 400 for a vehicle shown in fig. 6, the 1 st functional member 14 and the 2 nd functional member 15 are entirely overlapped when the 1 st glass plate 10 is viewed from above. Further, 2 functional members are present on the inner side than the peripheral edge of the 1 st glass plate 10. In addition, the 1 st functional member 14 and the 2 nd functional member 15 may have portions that overlap at least partially and do not overlap each other when the 1 st glass plate 10 is viewed from above.
In the laminated glass 400 for a vehicle according to the present embodiment, the peripheral edges of 2 functional members overlap each other when the 1 st glass plate 10 is viewed from above. In order to reduce the residual air bubbles without forming gaps at the peripheral edge portions of the functional members, the laminated glass 400 for a vehicle has the following configuration.
FIG. 7 shows an X of a laminated glass 400 for a vehicle according to embodiment 4 1 -X 2 A cross-sectional view. In fig. 7, the interlayer 20 is laminated in the order of the 1 st interlayer 11, the 1 st adjustment interlayer 21, the 2 nd adjustment interlayer 22, and the interlayer 12 from the 1 st glass plate 10 side. Furthermore, the 1 st functional member 14 and the 2 nd functional member 15 are sandwiched by each otherIs held between the 1 st intermediate film 11 and the 2 nd intermediate film 12, and does not exist on the same plane.
Then, as shown in fig. 7, the vehicle laminated glass 400 has the 1 st adjustment intermediate film 21 on the outer side of the peripheral edge of the 1 st functional member 14, and has the 2 nd adjustment intermediate film 22 on the outer side of the peripheral edge of the 2 nd functional member 15. The 2 nd adjustment intermediate film 22 has an outer edge shape substantially identical to the outer edge shape of the 1 st glass plate 10 and an inner edge shape (hollowed-out portion) substantially identical to the outer edge shape of the 2 nd functional member 15 when the 1 st glass plate 10 is viewed from above.
In addition, when the outer edge shapes of the 1 st functional member 14 and the 2 nd functional member 15 are substantially the same in the plan view of the 1 st glass plate 10, the 1 st adjustment intermediate film 21 may be disposed outside the peripheral edges of both the 1 st functional member 14 and the 2 nd functional member 15. In this case, the 2 nd adjustment intermediate film 22 may not be provided, and only the 1 st adjustment intermediate film 21 may be provided. In addition, the vehicle laminated glass 400 may have an adhesive (not shown) between the 1 st functional member 14 and the 2 nd functional member 15 to reduce air bubble residue between the functional members.
In this way, in the laminated glass 400 for a vehicle, the interlayer 20 has the 1 st adjustment interlayer 21, or has the 1 st adjustment interlayer 21 and the 2 nd adjustment interlayer 22. Therefore, in the laminated glass 400 for a vehicle, the interlayer film 20 is easily adhered to the 1 st glass plate 10 and the 2 nd glass plate 18 at the peripheral edge portions of the functional members, and bubble residue can be reduced. The provision of these adjustment intermediate films can reduce stress applied to the glass during press-bonding. This can reduce the breakage caused by the primary stress at the time of press-bonding or the breakage caused by the residual stress in the market. The effects of the 1 st adjustment intermediate film 21 and the 2 nd adjustment intermediate film 22 are remarkable when the thickness of the 1 st adjustment intermediate film 21, or the 1 st functional member 14 and the 2 nd functional member 15 is 0.15mm or more, and are remarkable particularly when it is 0.18m or more.
Fig. 8 is a side view of a laminated glass 400 for a vehicle according to embodiment 4 including a power feeding side 10 s. As shown in fig. 8, the 1 st power supply body 16 and the 2 nd power supply body 17 are firmly held by the interlayer film 20 in the laminated glass 400 for a vehicle. In the present embodiment, the 1 st power supply body 16 is sandwiched between the 1 st adjustment intermediate film 21 and the 2 nd adjustment intermediate film 22, but it may be sandwiched between the 1 st intermediate film 11 and the 1 st adjustment intermediate film 21. In this case, the 2 nd power supply 17 may be sandwiched between the 1 st adjustment intermediate film 21 and the 2 nd adjustment intermediate film 22.
In the present embodiment, too, the distance from one glass plate (for example, the 2 nd main surface 10b of the 1 st glass plate 10) to the 1 st power supply body 16 is different from the distance from the main surface (10 b) of the glass plate to the 2 nd power supply body 17, and therefore, the interlayer 20 actively flows and easily fills each corner between the glass plates in the high-temperature and high-pressure environment in the manufacturing process. As a result, in the laminated glass 400 for a vehicle, bubble residue is less likely to occur, and the adhesion force between the glass plate and the interlayer film 20 is also improved.
(embodiment 5)
Fig. 9 and 10 show X of a laminated glass 500 for a vehicle according to embodiment 5 of the present invention shown in fig. 6, respectively 1 -X 2 A cross-sectional view and a side view comprising the current provider edge 10 s. As shown in fig. 9, an intermediate film 20 of a laminated glass 500 for a vehicle is different from embodiment 4 in that a 3 rd intermediate film 13 is provided between a 1 st functional member 14 and a 2 nd functional member 15 in a thickness direction (Z-axis direction). The 1 st functional member 14 is sandwiched between the 1 st intermediate film 11 and the 3 rd intermediate film 13, and the 2 nd functional member 15 is sandwiched between the 2 nd intermediate film 12 and the 3 rd intermediate film 13.
As shown in fig. 10, the 1 st power supply 16 is sandwiched between the 1 st adjustment intermediate film 21 and the 3 rd intermediate film 13, and the 2 nd power supply 17 is sandwiched between the 2 nd adjustment intermediate film 22 and the 2 nd intermediate film 12. However, the 1 st power supply body 16 may be sandwiched between the 1 st adjustment intermediate film 21 and the 2 nd adjustment intermediate film 22, or may be sandwiched between the 1 st intermediate film 11 and the 1 st adjustment intermediate film 21. The 2 nd power supply 17 may be sandwiched between the 3 rd intermediate film 13 and the 2 nd adjustment intermediate film 22.
In this way, in the laminated glass 500 for a vehicle according to the present embodiment, the 1 st functional member 14 and the 1 st power supply 16, and the 2 nd functional member 15 and the 2 nd power supply 17 are separated in the thickness direction by the 3 rd interlayer film 13. Thus, the 1 st functional member 14 and the 2 nd functional member 15 do not exist on the same plane. Further, the 1 st power supply body 16 and the 2 nd power supply body 17 do not exist on the same plane.
Therefore, the distance from the 2 nd main surface 10b of the 1 st glass plate 10 to the 1 st power supply 16 is different from the distance from the 2 nd main surface 10b of the 1 st glass plate 10 to the 2 nd power supply 17. Therefore, in the high-temperature and high-pressure environment in the manufacturing process of the laminated glass 500 for a vehicle, the interlayer 20 actively flows, and the corners between the glass sheets are easily filled. As a result, in the laminated glass 500 for a vehicle, bubble residue is less likely to occur, and the adhesion force between the glass plate and the interlayer film 20 is also improved.
Next, each constituent member included in the vehicle laminated glass 100 to 500 according to each embodiment of the present invention will be described in more detail. In the case of showing each constituent member, reference numerals used in fig. 1 to 10 are used, and reference numerals for the laminated glass for a vehicle are omitted.
< glass plate >)
The 1 st glass plate 10 and the 2 nd glass plate 18 may be flat plates, may be bent at least one, or may be bent both. The 1 st glass plate 10 and the 2 nd glass plate 18 may have a single curved shape (cylindrical shape) with a single curved direction, or may have a multi-curved shape with curved directions in 2 orthogonal directions.
The radius of curvature of the 1 st glass plate 10 is preferably substantially the same as the radius of curvature of the 2 nd glass plate 18 (particularly including the case of a flat plate) or larger than the radius of curvature of the 2 nd glass plate 18. Namely, the minimum radius of curvature (r) of the 2 nd glass plate 18 2 ) Minimum radius of curvature (r) with glass pane 1 10 1 ) The ratio is preferably 1.ltoreq.r 1 /r 2 。
In order to reduce the occurrence of wrinkles or perspective deformation of the intermediate film 20, r 1 And r 2 Preferably 500mm or more, more preferably 700mm or more. In addition, when the laminated glass for a vehicle has a curved shape, the maximum radius of curvature (R 1 ) And the maximum radius of curvature (R) of the 2 nd glass sheet 18 2 ) Preferably 100,000mm or less, more preferably 50,000mm or less, further preferably 30,000mm or less, particularly preferably 20,000mm or less.
At r 1 And r 2 When the substantially identical laminated glass for a vehicle is mounted on a vehicle, either one of the 1 st glass plate 10 and the 2 nd glass plate 18 may be disposed on the vehicle inside. And at r 1 And r 2 In the case where a different laminated glass for a vehicle is mounted on a vehicle, it is preferable that r corresponds to r in order to secure the strength of the laminated glass 1 And r 2 The glass plate with the larger value is arranged outside the vehicle. For example r 1 ＞r 2 In this case, the 1 st glass plate 10 may be disposed on the vehicle outside, and the 2 nd glass plate 18 may be disposed on the vehicle inside.
As the 1 st glass plate 10 and the 2 nd glass plate 18, conventionally known inorganic glass or organic glass used for vehicle window glass can be used. The composition of glass 1 st sheet 10 may be the same as or different from the composition of glass 2 nd sheet 18. Examples of the inorganic glass include ordinary soda lime glass, aluminosilicate glass, borosilicate glass, alkali-free glass, and quartz glass.
These glass sheets can be produced by any known method such as a float method, a fusion method, a roll method, a downdraw method, and the like. For the bending of the inorganic glass, gravity molding, press molding, or the like is used, and the glass sheet is bent at a high temperature. The inorganic glass may be unreinforced glass obtained by molding molten glass into a plate shape and cooling it slowly, or may be subjected to strengthening treatment such as physical strengthening (e.g., air-cooling strengthening) and chemical strengthening, if necessary.
Examples of the organic glass include polycarbonate resins, acrylic resins, polystyrene resins, aromatic polyester resins, polyarylate resins, polycondensates of halogenated bisphenol a and ethylene glycol, acrylic urethane resins, and acrylic resins containing halogenated aryl groups. The organic glass is preferably a polycarbonate resin from the viewpoint of obtaining a lightweight and flexible sheet. In addition, the above resins may be used in combination of 2 or more.
Of the above exemplified materials, the 1 st glass plate 10 and the 2 nd glass plate 18 are preferably soda lime glass or alkali-free glass. And glass sheets 1, 10 and 2, 18 are preferably float glass.
Both the inorganic glass and the organic glass are usually colorless, but may be colored as long as they have transparency. In the case of color, the privacy glass may be a so-called privacy glass having a dark color such as gray. The privacy glass has an effect of making it difficult to see the inside of the vehicle from the outside of the vehicle and an effect of reducing the transmission of sunlight from the outside of the vehicle to the inside of the vehicle and improving the aesthetic quality when seen from the inside and outside of the vehicle. Privacy glass is suitable for use in locations other than windshields, particularly in skylights, side glazings behind vehicles, rear glazings, triangular glazings, and the like. In addition, the inorganic glass and the organic glass may contain an infrared shielding material, an ultraviolet shielding material, or the like.
The thicknesses of the 1 st glass plate 10 and the 2 nd glass plate 18 may be appropriately selected according to the type, the location, etc. of the vehicle on which the laminated glass for a vehicle is mounted, but may be generally 0.1mm to 10mm, respectively. In order to make the density per unit area (areal density) obtained from the mass and surface area of the laminated glass 100 for a vehicle fall within the preferable ranges, the thicknesses of the 1 st glass plate 10 and the 2 nd glass plate 18 are preferably 0.3mm to 2.6mm. The thicknesses of the 2 glass plates 10, 18 may be the same or different from each other.
When the thickness of the 2 glass plates 10 and 18 is different, it is preferable in view of the flying stone impact resistance from the outside if the glass plate disposed on the vehicle outer side is thicker than the glass plate disposed on the vehicle inner side when the laminated glass for a vehicle is mounted on a vehicle. In this case, in the laminated glass for a vehicle, the difference between the thickness of the 1 st glass plate 10 and the thickness of the 2 nd glass plate 18 is preferably 0.3mm to 1.5mm, more preferably 0.3mm to 1.3mm, from the viewpoint of the flying stone impact resistance.
When the laminated glass for a vehicle is mounted on a vehicle, the thickness of the glass plate located on the vehicle outside is preferably 1.1mm or more, more preferably 1.3mm or more, still more preferably 1.6mm or more, and particularly preferably 1.8mm or more. The thickness of the glass plate located on the vehicle exterior side is preferably 2.6mm or less, more preferably 2.1mm or less.
On the other hand, when the laminated glass for a vehicle is mounted on a vehicle, the thickness of the glass plate located on the vehicle interior side is preferably 0.3mm or more, more preferably 0.5mm or more, still more preferably 0.7mm or more, particularly preferably 1.1mm or more, and most preferably 1.6mm or more. The thickness of the glass plate located on the vehicle interior side is preferably 2.6mm or less, more preferably 2.1mm or less.
In the 2 glass plates 10 and 18, a coating film imparting a water repellent function, a hydrophilic function, an antifogging function, and the like may be laminated on at least one of the surfaces exposed to the atmosphere (the 1 st main surface 10a, the 4 th main surface 18 d). Further, a coating film generally including a metal layer, such as a low-emissivity coating, an infrared light-shielding coating, or a conductive coating, may be laminated on the surfaces (the 2 nd main surface 10b, the 3 rd main surface 18 c) of the 2 glass plates 10, 18 facing each other.
< intermediate film >
As the intermediate film 20, a material used for a general laminated glass can be used, and examples thereof include thermoplastic resins, thermosetting resins, and photocurable compositions, and these resins can be cured to form the intermediate film. In addition, "curing" as used herein includes hardening.
The intermediate film 20 has various functions such as facilitating adhesion of members to each other, impact buffering, and sound insulation, which will be described later. From the viewpoint of adhesion, at least 2 or more of the 1 st intermediate film 11, the 2 nd intermediate film 12, the 3 rd intermediate film 13, the 1 st adjustment intermediate film 21, the 2 nd adjustment intermediate film 22, and the auxiliary intermediate film 25 are preferably composed of the same material, and more preferably the intermediate films 20 are all composed of the same material.
The interlayer 20 is laminated at different glass transition temperatures, and thus has sound insulation. As a 3-layer laminated structure having sound insulation, for example, the interlayer 20 may be configured such that a layer located at an intermediate position in the thickness direction is a core layer having a glass transition temperature of less than 15 ℃ and 2 layers sandwiching the core layer (intermediate layer) are surface layers having a glass transition temperature of 15 ℃ or more. As the 5-layer laminated structure having sound insulation, for example, the interlayer 20 may be formed by laminating a surface layer, a core layer, and a surface layer in this order. In this case, the laminated glass for a vehicle according to each embodiment has a sound-insulating effect in addition to the effect of reducing the residual air bubbles.
Examples of the thermoplastic resin include polyvinyl acetal resins such as polyvinyl butyral resins (PVB), polyvinyl chloride resins (PVC), saturated polyester resins, polyurethane resins, ethylene-vinyl acetate copolymer resins (EVA), ethylene-ethyl acrylate copolymer resins, and Cyclic Olefin Polymers (COP). The thermoplastic resin used for the intermediate film 20 is preferably PVB, EVA, polyurethane resin, or the like. These thermoplastic resins may be used alone or in combination of 2 or more. Typical thermosetting resins are silicone-based resins, acrylic resins.
A typical photocurable composition comprises a curable compound (A) having a curable group and a photopolymerization initiator (B). The photocurable composition may further contain, if necessary, a non-curable component other than the photopolymerization initiator (B). The non-curable component includes a non-curable polymer (C), a chain transfer agent (D), and other additives.
Examples of the curable compound (a) include compounds such as acrylic, silicone, urethane acrylate, and epoxy. Wherein the storage elastic modulus G' is easily adjusted to 5×10 2 Pa～1×10 7 From the viewpoint of Pa, the curable compound (a) is preferably a silicone or an acrylic urethane. Further, the curable compound (a) is more preferably an acrylic urethane from the viewpoint of easy adjustment of the gel fraction to 1% to 50%. If the photocurable resin is used for the interlayer 20, the laminated glass does not need to be heated in the pressure bonding step, and thus cracking or warpage due to heating does not occur.
The interlayer film 20 may use one of these resins alone or in combination. For example, materials having different properties may be used in the central portion and the peripheral portion of the vehicle laminated glass in order to ensure rigidity and sound insulation properties as the vehicle laminated glass. For example, the peripheral edge portion of the laminated glass for a vehicle may be a region in which the 1 st adjustment intermediate film 21 or the 2 nd adjustment intermediate film 22 is disposed when the 1 st glass plate 10 is viewed from above, and the central portion may be a region further inside than the outer peripheral portion.
The intermediate film 20 contains one of a thermoplastic resin, a thermosetting resin, and a photocurable composition as a main component. The interlayer film 20 may further contain 1 or 2 or more kinds of various additives such as an infrared absorber, an ultraviolet absorber, a colorant, a fluorescent agent, an adhesion regulator, a coupling agent, a surfactant, an antioxidant, a heat stabilizer, a light stabilizer, a dehydrating agent, a defoaming agent, an antistatic agent, and a flame retardant. The colored layer formed of the colorant can be used as a so-called light shielding tape layer for reducing glare of vehicle occupants caused by sunlight. For example, when a laminated glass for a vehicle is mounted on a vehicle, a light shielding tape layer may be provided in a tape shape along its upper edge.
From the viewpoint of ensuring operability, the total thickness of the intermediate film may be 0.1mm to 3.1mm. The thickness of the interlayer film per 1 layer is preferably 0.3 to 3.0mm from the viewpoint of securing penetration resistance, and more preferably 0.3 to 1.2mm, particularly preferably 0.3 to 0.8mm from the viewpoint of weight limitation of the laminated glass. The thickness of each intermediate film may be the same or different.
Functional component >, functional component
Hereinafter, the 1 st functional member 14 and the 2 nd functional member 15 are also simply referred to as "functional members". The functional member is a layer to which power is supplied from a power source by a power supply body to perform electric driving. The functional member to be electrically driven may be a light modulation layer, a light emitting layer, an electrothermal layer, or the like. It is sufficient that the functional member is entirely constituted by a portion that is electrically driven. On the other hand, for example, the infrared light-shielding coating film or the resin film that emits light by ultraviolet rays, which is disposed between the 1 st glass plate 10 and the 2 nd glass plate 18, is not included in the functional member because it is not electrically driven, though it entirely constitutes a plane.
The 1 st functional member 14 and the 2 nd functional member 15 may be layers having the same function or layers having different functions. For example, the 1 st functional member 14 may be a light modulation layer and the 2 nd functional member 15 may be a light emitting layer, the 1 st functional member 14 may be a light emitting layer and the 2 nd functional member 15 may be an electrothermal layer, or the 1 st functional member 14 and the 2 nd functional member 15 may be light modulation layers. These combinations are merely examples, and combinations of functional members may be arbitrarily selected.
The light control layer may be one that changes color as long as it has a function of changing visible light transmittance by electric driving. Examples of the light control layer include an Electrochromic (EC) film, a Liquid Crystal (LC) film, a Suspended Particle Device (SPD) film, and an Electrodynamic (EK) film. The dimming layer may also be used as a shading tape.
The light-emitting layer may include a material that emits light by electric driving, and examples thereof include a cold cathode tube (CCFL), a light-emitting diode (LED), an organic light-emitting diode (OLED), a laser, and a display using these materials. The light-emitting layer may be used as a display for indicating a direction or for reminding attention.
The electrothermal layer may contain at least 1 of a metal, a metal oxide, and a conductive polymer, as long as the electrothermal layer contains a material that generates heat by electric drive. The electrothermal layer may be any shape, and examples of the shape include a film shape and a thin wire shape. In addition, the electrothermal layer may be an electrothermal film for antifogging, an electrothermal wire for ice melting, or the like.
< Power supply body and foil-shaped conductor >)
The direction in which the foil conductors 36 and 36' of the 1 st power supply body 16 are separated from each other may be the thickness direction of the laminated glass for a vehicle. However, in this case, since the thickness of the 1 st power supply body 16 increases and bubble residue may be more likely to occur after the intermediate film 20 is sealed, the direction of separation from each other is preferably a planar direction. The same is true for the foil conductors 37 and 37' of the 2 nd current supply 17.
Further, the foil-like conductor 36 'and the foil-like conductor 37' may be conductors driven at the same potential. Specifically, if the foil conductor 36 'and the foil conductor 37' are ground lines, the contact is not shorted, and the functional member can be prevented from being damaged.
The insulating material may be a thermosetting resin or a thermoplastic resin. Examples of the insulating material include polyester resins such as polyethylene terephthalate (PET), polyethylene naphthalate (PEN), and polybutylene terephthalate (PBT), polyamide resins such as nylon 6, nylon 66, and nylon 610, polyimide resins such as polyimide, polyamideimide, and polyether imide, and resins such as fluorine resins, polyethersulfone, polyetherketone, polyethersulfide, polyarylate, polyester ether, wholly aromatic polyamide, polyaramid, polypropylene (PP), polycarbonate (PC), and liquid crystal polymer.
Among these resins, polyimide resins such as polyimide resins that can withstand high temperature and high pressure conditions during the production of laminated glass for vehicles are suitably used as the insulating material. However, the resin used as the insulating material is not particularly limited as long as it is a material having insulating properties, flexibility and heat resistance. The material constituting the foil conductors 36, 36', 37' is preferably a metal such as gold, silver, or copper, and more preferably copper. In addition, the material may be carbon instead of metal. The foil conductors may be of the same material or of different materials.
The thickness of the foil-shaped conductor also depends on the kind of the functional member, but in order to correspond to the functional member used in the laminated glass for a vehicle, if each layer is 0.01mm or more, the width of the power supply body is not too wide, so that it is preferable in terms of operation, more preferably 0.05mm or more, still more preferably 0.07mm or more. Further, the thickness of the foil-like conductor is preferably 0.4mm or less, more preferably 0.2mm or less, and particularly preferably 0.1mm or less, since the power supply does not become excessively thick for each layer.
If the thickness of the power supply is 0.1mm or more at the portion including the foil-shaped conductor, the power supply is not easily broken even when exposed to vibration of a vehicle or the like, and therefore, it is preferable that the thickness is 0.15mm or more, and more preferably 0.2mm or more. Further, if the thickness of the power supply is 0.8mm or less at the portion including the foil-shaped conductor, the influence of the level difference due to the auxiliary interlayer or the like can be suppressed, and therefore, it is preferable that the thickness is 0.6mm or less, more preferably 0.4mm or less, and particularly preferably 0.3mm or less.
If the thickness of the power supply is 0.08mm or more at a portion not including the foil-shaped conductor, the power supply is not easily broken, and thus is preferably 0.1mm or more, more preferably 0.12mm or more. The upper limit of the thickness of the power supply member at the portion not including the foil-shaped conductor may be substantially equal to or less than the thickness of the portion including the foil-shaped conductor.
< shading part >)
The laminated glass for a vehicle may have, for example, a light shielding portion 50 having a width from the power feeding side 10s toward the central portion and overlapping at least a part of the peripheral edges of the 1 st functional member 14 and the 2 nd functional member 15. The width of the light shielding portion 50 is preferably 5mm or more from the peripheral edge of the 1 st functional member 14 or the 2 nd functional member 15 to the inside, since the peripheral edge of the functional member can be effectively hidden.
In the case where the vehicle laminated glass has the light shielding portion 50, the vehicle laminated glass has an opening portion that overlaps the 1 st glass plate 10 and is located at a portion where the light shielding portion 50 is absent when the 1 st glass plate 10 is viewed from above, thereby securing the driver's view. In order to secure the area of the opening, the width of the light shielding portion 50 is preferably 50mm or less, more preferably 30mm or less, and particularly preferably 20mm or less, from the peripheral edge of the 1 st functional member 14 or the 2 nd functional member 15 in the inward direction.
Examples of the material constituting the light shielding portion 50 include organic ink, inorganic ceramic, and colored intermediate film. The light shielding portion 50 may be formed by applying an organic ink or an inorganic ceramic to a glass surface by screen printing or the like, and drying the applied ink or inorganic ceramic. The color of the light shielding portion 50 may be any color as long as it can shield visible light to such an extent that it can be hidden at least in a portion to be hidden, and is preferably a dark color such as black, brown, gray, dark blue, or the like, and more preferably black. Hereinafter, as an example, an example is shown in which the light shielding portion 50 is constituted by a ceramic layer on a glass surface.
The ceramic layer constituting the light shielding portion 50 may be provided on at least one of the 2 nd main surface 10b and the 4 th main surface 18d, for example. The light shielding portion 50 provided on the 2 nd main surface 10b is advantageous in terms of concealment when viewed from the outside of the vehicle, and the light shielding portion 50 provided on the 4 th main surface 18d is advantageous in terms of concealment when viewed from the inside of the vehicle. The ceramic layers are preferably provided on the 2 nd main surface 10b and the 4 th main surface 18d so as to have excellent concealing properties when viewed from the inside and outside of the vehicle.
Next, a method for manufacturing a laminated glass for a vehicle according to the present invention will be described by taking the laminated glass 100 for a vehicle as an example.
Method for producing laminated glass for vehicle
The method for manufacturing the laminated glass 100 for a vehicle, in which the 1 st glass plate 10, the interlayer 20, and the 2 nd glass plate 18 are laminated in this order, includes (1) a lamination step and (2) a 1 st press bonding step, and the process proceeds to the step (2) after the step (1). The manufacturing method may further include (3) the 2 nd crimping step after the 1 st crimping step of (2).
(1) Lamination step
The lamination step is a step of preparing a laminate including the 1 st glass plate 10, the interlayer 20, the 1 st functional member 14 connected to the 1 st power supply 16, the 2 nd functional member 15 connected to the 2 nd power supply 17, and the 2 nd glass plate 18.
The intermediate film 20 has a 1 st intermediate film 11 and a 2 nd intermediate film 12. Specifically, the lamination step is a step of disposing the 1 st functional member 14 connected to the 1 st power supply 16 and the 2 nd functional member 15 connected to the 2 nd power supply 17 so as to be located between the 1 st interlayer 11 and the 2 nd interlayer 12. In the lamination step, the peripheral edges of the 1 st functional member 14 and the 2 nd functional member 15 are preferably disposed further inward than the peripheral edge of the 1 st glass plate 10.
The lamination step may be a step of preparing a laminate so as to obtain the laminated glass 100 for a vehicle shown in fig. 1 to 3 when the 1 st pressure bonding step (2) or the 2 nd pressure bonding step (3) described later is performed. In any case, at least a part of the 1 st power supply body 16 and the 2 nd power supply body 17 intersect only the power supply side 10s that is one side of the 1 st glass plate 10 when the 1 st glass plate 10 is viewed in plan, and the 1 st power supply body 16 and the 2 nd power supply body 17 do not overlap in the plane of the 1 st glass plate 10.
The inventors have noted that, in the 1 st glass plate 10 in plan view, the thicknesses of the interlayer 20 and the power supply body change in the 1 st pressure bonding step of (2) or in the 2 nd pressure bonding step of (3) described later, at the portion where the laminate body overlaps the power supply body and the portion where the laminate body does not overlap the power supply body. Then, the inventors have conducted intensive studies and found the following formulas (1) and (2) using a value of 0.8 as a weight. (1) In the lamination step, when viewed from the side view angle including the power feeding side 10s of the 1 st glass plate 10, the air bubble residue of the laminated glass 100 for a vehicle can be reduced by satisfying the formula (1). Further, it is preferable that the formula (2) is satisfied at the same time, because the residual bubbles can be further reduced.
Formula (1): t is t i ≥0.8×(t F1 +t iF1 )
t i : thickness of interlayer film between 1 st power supply and 2 nd power supply in plane direction (X-axis direction)
t F1 : thickness of thickest part of 1 st power supply body
t iF1 : thickness of intermediate film overlapping with 1 st power supply body
Formula (2): t is t i ≥0.8×(t F2 +t iF2 )
t F2 : thickness of thickest part of No. 2 power supply
t iF2 : thickness of intermediate film overlapping portion with the 2 nd power supply body
In the lamination step (1), the vehicle laminated glass 100 in which the 1 st glass plate 10, the interlayer 20, and the 2 nd glass plate 18 are sufficiently adhered can be manufactured by satisfying the formula (3) when viewed from the side view including the power feeding side 10s of the 1 st glass plate 10. Further, by satisfying the expression (4) at the same time, the laminated glass 100 for a vehicle can be manufactured more advantageously.
Formula (3): 1.2× (t F1 +t iF1 )≥t i
Formula (4): 1.2× (t F2 +t iF2 )≥t i
Fig. 11 (a) to (c) are side views of the 1 st glass plate 10 of the laminate including the power feeding edge 10 s. In fig. 11 (a), the extracted portions shown in fig. 11 (b) are shown by broken lines, respectively, in the portion where the 1 st glass plate 10 is viewed from above and the 1 st power supply 16 is overlapped, in the portion where the 1 st power supply 17 is overlapped, and in the portion where the 1 st power supply 16 and the 2 nd power supply 17 are overlapped, in the portion between the planar directions (X-axis directions) of the laminate. Fig. 11 (b) shows a broken line portion of fig. 11 (a). Fig. 11 (c) is an enlarged view of the vicinity of the 1 st power supply body 16 and the 2 nd power supply body 17 in fig. 11 (a) and 11 (b). The thickness of each member of the above formulas (1) and (2) will be described with reference to fig. 11 (b) and 11 (c).

The 1 st pressure bonding step may be a step of bonding the laminate obtained in the lamination step by placing the laminate in, for example, a vacuum bag, sandwiching the laminate by a pair of rolls, or covering the peripheral edge with a rubber chamber. The 1 st crimping step is usually performed at a temperature of 50 to 130 ℃. The absolute pressure when using a vacuum bag is preferably 36kPa to 1kPa.
(3) 2 nd crimping step
If necessary, the method may further include a 2 nd pressure bonding step of further firmly bonding the laminate obtained in the lamination step after the 1 st pressure bonding step. The 2 nd pressure bonding step is carried out by placing the laminate in an autoclave, for example, and controlling the temperature to 110 to 150 ℃ and the absolute pressure to 0.98 to 1.47MPa for a predetermined time. The 2 nd pressure bonding step is preferably kept under a higher temperature and higher pressure than the 1 st pressure bonding step.
Hereinafter, the present invention will be specifically described with reference to examples, but the present invention is not limited to these examples.
Example 1 >
Example 1 is an example of a laminated glass 500 for a vehicle corresponding to embodiment 5. The 1 st glass plate and the 2 nd glass plate were made of light green glass (300 mm. Times.300 mm, thickness 2 mm) which is commonly used as a vehicle glass, the 1 st to 3 rd intermediate films and the 1 st and 2 nd adjustment intermediate films were made of polyvinyl butyral (PVB) (thickness 0.38mm, manufactured by Ind. Chemie, kyowa-ter Co., ltd.), and the 1 st and 2 nd functional members were made of Suspended Particle Devices (SPD) (manufactured by Hitachi chemical Co., ltd., thickness 0.34 mm). The size of the 1 st to 3 rd intermediate films was 300mm×300mm. As shown in table 1, the 1 st and 2 nd adjustment intermediate films have hollowed portions corresponding to the sizes of the 1 st and 2 nd functional members, and the portions other than the hollowed portions have a predetermined width.
TABLE 1
In the 1 st and 2 nd power supplies (thinnest part 0.13mm, thickest part 0.24 mm), tin-coated copper foil (thickness 0.1 mm) was coated with polyimide (thickness 0.13mm, width 360 mm) via an epoxy adhesive.
The laminated glass for a vehicle of example 1 was obtained through a lamination step, a 1 st pressure bonding step, and a 2 nd pressure bonding step. In the lamination step, the 2 nd intermediate film, the 2 nd adjustment intermediate film, the 2 nd functional member electrically connected to the 2 nd power supply, the 3 rd intermediate film, the 1 st adjustment intermediate film, the 1 st functional member electrically connected to the 1 st power supply, the 1 st intermediate film, and the 1 st glass plate are laminated in this order from the lower layer of fig. 9 and 10 on the 2 nd glass plate. Thus, t i ＝t iF1 ＝t iF2 ＝1.9mm，t F1 ＝t F2 =0.24 mm, satisfying the above-described formulas (1) and (2).
[ evaluation ]
In the laminated glass for a vehicle after the 2 nd pressure bonding step, the 1 st glass plate was observed in plan view in the following ranges of the region (a) and the region (b), and the presence or absence of the residual air bubbles was confirmed. When 1 or more bubbles having a diameter of 1mm or more were confirmed, the bubbles were determined to remain. Region (a): 20mm or more inside the peripheral edge of the 1 st functional member (2 nd functional member), region (b): between the 1 st power supply and the 2 nd power supply.
Then, as shown in table 2, the optimum difference was evaluated as good (good), good (fair), and bad (bad) in order from the optimum difference. The results are shown in Table 3.
TABLE 2
[ Table 3 ]
In example 1, the power supply distance d between the 1 st power supply and the 2 nd power supply is set 1 A distance d of 45mm or less and/or from the power supply side to the periphery of the 1 st functional member (2 nd functional member) 2 When the thickness was 60mm or less, it was confirmed that no bubbles remained in the regions (a) and (b) after the 2 nd crimping step.
[ Beck test ]
The laminated glass for a vehicle of the present invention is also expected to be used in a long-term, high-temperature environment. In a high-temperature environment, the compressed and dissolved air may expand, and foam (residual bubbles) may be generated more than in the stage after the 2 nd pressure bonding step, or bubbles may remain which are not confirmed after the 2 nd pressure bonding step. Therefore, in example 1, the laminated glass for a vehicle after the 2 nd pressure bonding step was left to stand in an oven, heated at 100 to 130 ℃ for 2 hours, and subjected to an accelerated foaming test.
TABLE 4
In example 1, the distance d between the power supplies is set to 1 At a distance of 45mm or less 2 In the case of 60mm or less, even after the beck test, it was confirmed that no bubble remains were generated on at least one of the 1 st functional member (2 nd functional member) 20mm or more inside the peripheral edge or between the 1 st power supply and the 2 nd power supply.
