Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a long trim material to be attached to joints in buildings, corners in furniture, gaps between doors in automobiles, and the like, and a method of manufacturing the same.

[0002]

2. Description of the Related Art Conventionally, for example, as a joint material for filling a gap between adjacent building boards on an outer wall surface of a building,
As a protector material used to prevent injuries in corners of furniture, etc., or as a packing material or sealing material to close gaps created in doors of automobiles
A long trim material is used. For example, Japanese Patent Application Laid-Open No. 58-20541 and Japanese Patent Application Laid-Open
434 and Japanese Utility Model Laid-Open No. 4-43608. In these long trim materials, a synthetic resin core material that is harder than the rubber member on the surface is provided inside to stabilize the cross-sectional shape of the long trim materials and improve their strength. Let me.

[0003]

However, these long trim materials have the following problems.
That is, when the trim material is extruded, the trim material is subjected to, for example, a pressure and a back pressure generated when rubber, which is a material being molded, flows backward in the direction opposite to the direction in which the molding proceeds. At that time, the trim material may be broken or cut due to insufficient tensile strength. Further, when constructing a long trim material, the trim material is constructed while being pulled in the longitudinal direction. At this time, since the tensile strength in the longitudinal direction is not sufficient, the trim material may be deformed and elongated.

The present invention has been made in view of the above-mentioned conventional problems, and an object of the present invention is to provide a long trim material which has a tensile strength and is easy to apply, and a method of manufacturing the same.

[0005]

The invention according to claim 1 has a main body made of a synthetic resin or rubber, and a resin core made of a hard thermoplastic resin disposed inside the main body, and The resin core material is a long trim material which is stretched in the longitudinal direction.

What is most notable in the present invention is that the resin core material is stretched in its longitudinal direction. Here, the stretching process is a process of stretching the extruded resin core material to a length of at least one time in the longitudinal direction or the width direction.

Next, the function and effect of the present invention will be described.
The long trim material in the present invention has the above resin core material inside. This resin core has greater strength than the main body, which is the outer layer of the trim material. Therefore, for example, when the trim material is used as a joint material in a building or as a sealing material or a packing material in a gap in a door part of an automobile, the tensile strength of the trim material is maintained while maintaining the sealing effect of the main body. Can be enhanced. Also, for example, when using a trim material as a protect material for corners of furniture, etc.,
The tensile strength of the trim material can be increased while maintaining the effect of preventing injury and the like.

[0008] The resin core material is stretched in the longitudinal direction. That is, the tensile strength of the resin core material that has been subjected to stretching processing is higher than that of the resin core material that has been extruded. Therefore, the tensile processing can improve the tensile strength of the resin core material. Therefore, the tensile strength of the trim material using the resin core material can be further improved.

Further, when the main body is extruded and formed on the surface of the resin core material, for example, the rubber, which is the material being formed, flows into the main body in a direction reverse to the direction in which the molding proceeds. Pressure and back pressure. However, even in this case, the trim material being formed does not crack or cut for the above-described reason. Further, for example, when the trim material is applied, even if the trim material is pulled in the longitudinal direction, the trim material does not deform and expand. Therefore, the trim material can be easily applied. In addition, since the resin core is made of a hard thermoplastic resin, the resin core is less deformed than a soft thermoplastic resin.

As described above, according to the present invention, it is possible to provide a long trim material which has a tensile strength and is easy to apply.

Next, as in the second aspect of the present invention, it is preferable that the resin core material has a strip shape. This facilitates the stretching process.

Next, as in the third aspect of the present invention, the elongated trim member has a decorative portion and a support portion formed on the back side of the decorative portion. It is preferable that the resin core is disposed inside at least one of the support portions. Accordingly, the trim part can be attached by inserting the support portion into a gap portion in a building, furniture, or the like, and the decorative portion having excellent appearance design can cover the portion. Therefore, the installation of the trim material is further facilitated, and excellent appearance and design can be exhibited.

Next, the resin core material preferably has a plurality of convex portions and concave portions on the surface thereof. Thereby, the convex portion can bite into the main body portion, and the main body portion can enter the concave portion. Therefore, the main body and the resin core material are firmly connected. Therefore, they can be prevented from being separated.

Next, as in the fifth aspect of the present invention, the convex portion includes a plurality of convex portions extending in an oblique direction with respect to the longitudinal direction, and an intersecting portion extending so as to intersect with the convex portion. It is preferable that the intersecting convex portion and the convex portion form a diamond-shaped projecting frame.

[0015] Thus, the convex portion can bite into the main body in the longitudinal direction and the width direction. Further, the main body can enter into the concave portion surrounded by the protruding frame. Therefore, the main body and the resin core material are more firmly connected. Therefore, the tensile strength of the trim material can be further improved.

Next, it is preferable that the resin core is stretched in the width direction as well. This allows the resin core material to have a large tensile strength not only in the longitudinal direction but also in the width direction. Therefore, a trim material having a large tensile strength in either of these directions can be manufactured.

Next, as in the invention according to claim 7, the resin core material may be bent or bent in a U-shaped or L-shaped cross-sectional shape. Thus, when it is desired to manufacture a trim material having a bent shape, for example, when attaching to a flange of a body in a door portion of an automobile or the like, a resin core material is formed in a bent or bent state and trimmed. It can be placed inside the material.

Although there is no strict distinction between the bent state and the bent state, the bent state can be roughly classified into a sharp bend, that is, a shape having a small bend R, while the bent state is a gentle bend. That is, it is formed in a shape having a large bend R. That is, the resin core material can be formed in various shapes.

Next, as in the present invention, it is preferable that a string-shaped core material is provided near the resin core material. This can prevent deformation such as bending caused by heating the trim material during molding of the trim material. In addition, the tensile strength of the trim material 1 can be further improved. Further, this can prevent the trim material from shrinking after the trim material is formed. Further, even after the trim material is applied, it is possible to prevent the trim material from contracting due to heat.

Next, as in the invention according to the ninth aspect, the resin core material has a tensile strength of 50 in the longitudinal direction.
It is preferably 0 kgf / cm ² or more. Accordingly, the trim material is not cracked or cut during the application of the trim material or the extrusion molding.

The tensile strength is 500 kgf / c.
When it is smaller than m ² , the trim material may be cracked or cut during the above-mentioned construction or the above-mentioned extrusion molding. The upper limit of the tensile strength is considered as follows. That is, it is difficult to mold the resin core material to have a tensile strength exceeding 5000 kgf / cm ² due to the properties of the material used for the resin core material. Therefore, the upper limit is 5
000 kgf / cm ² .

According to a tenth aspect of the present invention, there is provided a method of manufacturing a long trim material having a resin core built therein by extruding a main body made of a synthetic resin or rubber around a resin core. The method for producing a long trim material is characterized in that the resin core material is stretched in the longitudinal direction in advance in the molding.

The resin core material of the present invention is stretched in the longitudinal direction. By this stretching, the resin core material can have high strength. for that reason,
When the main body is extruded and formed on the surface of the resin core material, for example, pressure and back pressure generated by rubber, which is a material being formed in the main body, trying to flow backward in a direction opposite to the direction of molding. As a result, the trim material during molding is not cracked or cut. Therefore, the molding of the trim material does not stop due to these abnormalities. Therefore, the molding of the trim material can be stabilized. In addition, the same functions and effects as the first aspect of the invention can be obtained. Therefore, it is possible to provide a method for producing a long trim material which has a tensile strength and is easy to perform.

Next, as in the invention according to claim 11,
It is preferable that the resin core material is manufactured by extruding the hard thermoplastic resin and then stretching the same. Thereby, the resin core material can be sufficiently stretched, and a trim material having a desired strength can be obtained.

Next, according to the twelfth aspect of the present invention,
It is preferable that the resin core material is also stretched in the width direction. This allows the resin core material to have a large tensile strength not only in the longitudinal direction but also in the width direction. Therefore, a trim material having a large tensile strength in either of these directions can be manufactured.

The long trim material 1 in this example has a main body 2 made of a synthetic resin or rubber, and a resin core 3 made of a hard thermoplastic resin disposed inside the main body 2. The resin core material 3 is stretched in the longitudinal direction.

The details will be described below. The resin core material 3
Is formed in a strip shape. The resin core 3 has
A polypropylene resin was used. And the resin core material 3
After the stretching, heat treatment such as annealing is performed to remove the internal stress in the core material. In addition, the resin core material 3
In addition, for example, a polyethylene terephthalate resin or a polyamide resin can be used. The main body 2 was made of ethylene-propylene-diene rubber (EPDM). The main body 2 has an EPDM
When the resin core 3 is used, it is preferable to use a polypropylene resin or a polyethylene resin for the resin core material 3 in consideration of bonding to the main body 2.

As shown in FIG. 1, the long trim member 1 has a decorative portion 21 and a support portion 22 formed to project from the back side of the decorative portion 21. The resin core material 3 is disposed inside the support portion 22. In addition, the support 2
2 has two protruding fins 23 on the left and right, respectively. The protruding fins 23 are elastically bent when the trim material 1 is installed in the gap 62 between the adjacent building boards 61 and the like, and can exert a sealing effect as a sealing portion. In addition, at this time, the trim member 1 can be elastically bent and exert an effect as a support portion that makes it difficult for the trim material 1 to come off from the gap 62 (see FIG. 2). In this example, the trim material 1 is a joint material used for a portion of the gap 62 of the adjacent building board 61 or the like. The support 22
Are columnar legs inserted into gaps 62 between adjacent building boards 61.

Further, a hard surface cover 221 is provided on the surface of the decorative portion 22. This front cover 221
Is made of chlorosulfonated polyethylene and is molded integrally with the decorative portion 21 by fusing. Further, when the trim material 1 is applied, it can be applied by hitting the front cover 221.

Next, as shown in FIG.
For example, the building boards 6 adjacent to each other in the building 6
A description will be given of a case where the work is applied to the first gap 62. At this time, the support portion 22 is inserted into the gap 62 while being beaten from the surface of the decorative portion 21. At this time, the support 22
The protruding fin 23 is bent elastically at the
Get in between. At this time, one end of the trim member 1 is inserted while being pulled so that the trim member 1 does not bend.

Hereinafter, a method of manufacturing the trim material 1 will be described. Here, in this production, as shown in FIG. 3, a production device 5 for the trim material 1 is used. First,
A material of a hard thermoplastic resin which is a molding material of the resin core material 3 is charged into the first extruder 51. Then, in the first extruder 51, the resin core material 3 is extruded. Then, the resin core material 3 after extrusion molding is passed through a longitudinal stretching machine 52, and the resin core material 3
Is stretched in the longitudinal direction.

Next, in the second extruder 53, a synthetic resin or rubber material, which is a molding material for the main body 2, is charged, and the stretched resin core 3 is passed through the second extruder 53.
At this time, the synthetic resin or rubber molding material is adhered to the periphery of the resin core 3, and the main body 2 is extruded so as to include the resin core 3, thereby forming the trim material 1. Thereafter, the trim material 1 is passed through a vulcanizing tank 54 to improve the elasticity of the main body 2, and then cooled through a cooling tank 55. Then, the trim material 1 is taken out by the take-up machine 56 and cut by the cutting machine 57 to a desired length.

Here, the longitudinal stretching machine 52 will be described in detail. As shown in FIG. 4A, the longitudinal stretching machine 52 is configured by a plurality of rollers 525. These rollers 52
5 is provided in a meandering manner in the surface direction of the resin core material 3. Since the resin core material 3 has elasticity, the rollers 52
5 is arranged in a meandering state along the surface. Further, tension is applied to the resin core material 3 in a direction in which the resin core material 3 is to be extended.

The resin core material 3 is stretched by a difference in peripheral speed due to rotation of the roller 525. That is, these rollers 525 are rotated so that the peripheral speed becomes higher than that of the immediately preceding roller 525. That is, the peripheral speed of the roller 525 is V1 <V2 <V3 <V4 <V
5 is set. Since the resin core material 3 is sent in contact with the surfaces of the rollers 525,
Stretching is performed due to the difference in peripheral speed. The above vertical stretching machine 5
4, as shown in FIG. 4B, a plurality of rollers 525 may be arranged in parallel to arrange the resin core material 3 in a straight line. Also in this case, the peripheral speeds are set to V6 <V7 <V8 in the same manner as described above.

The resin core material 3 in this embodiment is extruded in the first extruder 51 and stretched in the longitudinal stretching machine 52. On the other hand, the above-mentioned extrusion molding and stretching of the resin core material 3 do not have to be performed simultaneously with molding of the trim material 1. That is, the resin core material 3 is processed in advance, and a supply device for the resin core material 3 is provided in place of the first extruder 51 and the longitudinal stretching machine 52, and the resin core material 3 is extruded by the second extruder 51 and the vertical stretching machine 52. May be supplied to the machine 53.

The manufacturing apparatus 5 is mainly used for extruding rubber in the second extruder 53. On the other hand, when extruding the synthetic resin in the second extruder 53, the vulcanization tank 54 may not be used.

Next, the operation and effect of this embodiment will be described. The long trim material 1 in this example has the resin core material 3 therein. The resin core 3 has a greater strength than the main body 2, which is the outer layer of the trim 1.
Therefore, for example, when the trim material 1 is used as a joint material in the building 6 or as a sealing material or a packing material in a gap 73 (see FIG. 7 described later) of the door portion 7 in an automobile, the sealing by the main body portion 2 is used. The tensile strength of the trim material 1 can be increased while maintaining the effect. Further, for example, when the trim material 1 is used as a protect material for a corner portion of furniture or the like, the tensile strength of the trim material 1 can be increased while maintaining the effect of preventing injury and the like.

The resin core material 3 is stretched in the longitudinal direction. That is, the tensile strength of the resin core material 3 that has been subjected to stretching processing is higher than that of the resin core material 3 that has been extruded. Therefore, the tensile strength of the resin core material 3 can be improved by this stretching process. Therefore, the tensile strength of the trim material 1 using the resin core material 3 can be further improved.

When the main body 2 is extruded and formed on the surface of the resin core material 3, for example, the rubber, which is the material being molded, flows backward in the main body 2 in the direction opposite to the direction in which the molding proceeds. Pressure, back pressure, etc., which are generated as a result. However, even in this case, the trim material 1 during molding does not crack or cut for the above-described reason. Also,
For example, when the trim material 1 is applied, even if the trim material 1 is pulled in the longitudinal direction, the trim material 1 does not deform and expand. Therefore, the trim material 1 can be easily installed. Further, since the resin core material 3 is made of a hard thermoplastic resin, the resin core material 3 is less deformed than a soft thermoplastic resin.

Further, the trim material 1 includes a decorative portion 21 and
A support portion 22 is formed on the back side of the decorative portion 21 so as to protrude. Therefore, the trim member 1 can be attached by inserting the support portion 22 into a gap portion in a building, furniture, or the like, and the decorative portion 21 having excellent appearance design can cover the portion. For this reason, it is easier to apply the trim material 1 and it is possible to exhibit excellent appearance and design. The resin core material 3 is disposed inside the support portion 22. Therefore, when the trim material 1 is applied, the support portion 22 can be easily inserted into the gap.

In this embodiment, the resin core 3 is stretched 12 times in the longitudinal direction. This stretching process can be stretched about 2 to 20 times in the longitudinal direction, but is preferably 10 to 14 times as much as possible.
Further, in the present embodiment, the resin core material 3 is formed in a strip shape, but as shown in FIG. 5, it may be formed to have an elliptical cross section. Also in this case, the same trim material 1 as described above can be manufactured.

The support portion 25 has a plurality of projecting fins 2 for fixing to the flange 711 on the inner surface side.
51. This protruding fin 251 is made of trim material 1
Is supported by the flange portion to serve as a support portion for supporting the trim material 1 and also as a seal portion for preventing infiltration of moisture and the like into the interior side of the vehicle. In addition, the outer surface side of the support portion 25 also serves as a decorative portion in consideration of the appearance and design of the portion where the trim material 1 is mounted.
The packing part 24 is made of a sponge-like ethylene-
The bearing 25 is made of solid ethylene-propylene rubber.

In this example, the trim material 1 was formed by the following method. First, as shown in FIG. 11 described later, a horizontal stretching process and a vertical stretching process are performed on the flat resin core material 3 using a horizontal stretching machine 521 and a vertical stretching machine 522. Next, in the second extruder 53, the main body 2 is extruded around the resin core material 3 to form the trim material 1 (see FIG. 3). Next, the trim material 1 is passed through a vulcanization tank 54 to improve the elasticity of the main body 2 (see FIG. 3), and then cooled through a cooling tank 55. Thereafter, the support portion 25 having the resin core material 3 therein is bent and formed into a U-shape. Subsequent steps are the same as in the first embodiment.

The resin core material 3 may be bent so as to have a U-shape to some extent in the cross-sectional view after performing the above-mentioned transverse stretching and longitudinal stretching. In this case, the sheet is formed into a final U-shape by performing bending again after the cooling. Other configurations are the same as those of the first embodiment.

The resin core material 3 in this embodiment is formed by bending into a U-shape. In this case, the resin core material 3 is liable to crack in the width direction when bent in a U-shape.
It is preferable to perform the stretching process in the width direction as well as in the longitudinal direction as in this example. In addition, the same functions and effects as those of the first embodiment can be obtained.

It has a tensile strength of gf / cm ² or more.

As shown in FIGS. 9A and 9B,
The resin core material 3 has a plurality of convex portions 31 on both surfaces thereof. The convex portion 31 includes a plurality of convex portions 311 extending obliquely to the longitudinal direction, and the convex portions 311.
And intersecting convex portions 312 extending so as to intersect with each other. And the convex part 311 and the cross convex part 312 are
A diamond-shaped projecting frame 313 is formed.

The trim material 1 has a cord-shaped core material 4 near both sides of the resin core material 3 in the support portion 22. This cord-shaped core material 4 has a sufficient tensile strength in the longitudinal direction such that the trim material 1 does not stretch or cut when the trim material 1 is formed or when the trim material 1 is applied. Is preferred. Specifically, as the cord-shaped core material 4, a material made by twisting or knitting glass fiber yarn can be used. In addition, a brass wire stretched into a wire shape or the like can also be used. The sectional shape is not limited to a circle but may be a square or the like.

When rubber is used for the main body 2 as a molding material, the string-shaped core 4 is coated with a heat-activated adhesive or the like on the surface thereof, and the adhesive is applied in the vulcanizing tank 54. It is preferable to activate and adhere to the main body 2. In addition, the cord-shaped core material 4 is a resin core material 3 in the decorative part 21.
May be provided only in the vicinity of. FIG. 10 (a),
As shown in (b), the convex portion 31 is cut into the main body 2. In addition, the main body 2 enters into a concave portion surrounded by the protruding frame 313.

In forming the trim material 1 in this embodiment, as shown in FIG. 11, a trim material 1 manufacturing apparatus 5 is used. In the manufacturing apparatus 5, the resin core material 3 is stretched using a horizontal stretching machine 521 and a vertical stretching machine 522 instead of the vertical stretching machine 52 in the first embodiment. In this example, the vertical stretching is performed after the horizontal stretching is performed, but the order may be reversed.

Thereafter, the convex portions 31 are formed on both surfaces of the resin core material 3 by using the surface treatment machine 523. In addition, the convex portion 31 is provided with a roller 525 of the vertical stretching machine 522.
Thus, it can be formed simultaneously with the longitudinal stretching. next,
In the second extruder 53, the resin core material 3 is supplied, the molding material for the main body 2 is supplied, and the supply device 524 for the cord-shaped core material 4 is supplied.
The cord-shaped core material 4 is supplied to perform extrusion molding. Subsequent steps are the same as in the first embodiment. In addition, in this example, since the resin core material 3 is arrange | positioned at the decoration part 21 and the support part 22, the horizontal stretching machine 521 and the vertical stretching machine 522 use two systems. Also, for the cord-shaped core material 4,
24 are used in two systems.

Here, the horizontal stretching machine 521 and the vertical stretching machine 522 will be described in detail. As shown in FIGS. 12A and 12B, the horizontal stretching machine 521 is formed by arranging a plurality of rollers 525 in a direction inclined with respect to the longitudinal direction. And, the width of the resin core material 3 can be increased by the inclination. In addition, the vertical stretching machine 5
22 is formed by arranging a plurality of rollers 525 in parallel with the longitudinal direction. Then, tension is applied to the resin core material 3 in a direction in which the resin core material 3 is to be extended.

The resin core material 3 is stretched by a difference in peripheral speed due to rotation of the roller 525. That is, these rollers 525 are rotated so that the peripheral speed becomes higher than that of the immediately preceding roller 525. That is, in the horizontal stretching machine 521, the peripheral speed of the roller 525 is W1 <
The longitudinal stretching machine 522 is configured such that the peripheral speed satisfies U1 <U2 <U3 so that W2 <W3.
Since the resin core material 3 is sent in contact with the surfaces of the rollers 525, the resin core material 3 is stretched due to a difference in peripheral speed.
Other configurations are the same as those of the first embodiment.

In the trim material 1 in this embodiment, the resin core material 3 is also built in the decorative portion 21. Therefore, when the trim material 1 is applied, the linearity of the trim material 1 can be easily maintained. The resin core material 3 of the decorative part 21 and the resin core material 3 of the support part 22 are arranged in a direction crossing in a cross-sectional view thereof. Therefore, the linearity can be maintained well during extrusion molding and during storage of the trim material 1 after molding. Therefore, during extrusion molding,
Good molding can be performed without the trim material 1 being bent. Further, at the time of storage, the trim members 1 can be stored neatly without being bent. This also gives
In addition, the tensile strength of the trim material 1 can be improved.

The resin core 3 has a plurality of convex portions 311 and intersecting convex portions 312 on both surfaces thereof.
Therefore, the convex portions 311 and the intersecting convex portions 312 can bite into the main body 2. Further, the main body 2 can enter the concave portion surrounded by the protruding frame 313. Therefore, the main body 2 and the resin core material 3 are more firmly joined. Therefore, the tensile strength of the trim material 1 can be further improved.

In the vicinity of the resin core material 3, a cord-like core material 4 is provided.
have. Therefore, when the trim material 1 is heated in the vulcanizing tank 54, deformation such as bending of the trim material 1 can be prevented. Therefore, the tensile strength of the trim material 1 can be further improved.
This also prevents the trim material 1 from shrinking after the trim material 1 is formed. Further, even after the trim material 1 is constructed, the trim material 1
Can be prevented from shrinking due to heat.
