- the seal member 1 of the present embodiment includes a gel molded body 10 and an expansion suppressing body 20 which is provided inside the gel molded body 10 and suppresses expansion of the seal member 1 in the longitudinal direction.
- the seal member 1 has gel end portions 11 that do not have the elongation suppressing body 20 at both ends in the longitudinal direction.
- the seal member 1 is described as two members (hereinafter, “first member 60” and “second member 70”) like the frame-shaped casing 60A and the liquid crystal panel 70A in the liquid crystal display device (see FIG. 6). ) Is a member which is compressed and arranged (compressed arrangement).
- FIG. 1 shows a schematic view in which the seal member 1 is disassembled into layers.
- the seal member 1 is formed by laminating the front surface side gel molded body 10a, the elongation suppressing body 20, and the back surface side gel molded body 10b in this order from one surface side.
- the length in the longitudinal direction of the elongation suppressing body 20 is shorter than the length in the longitudinal direction of the front-side gel molded body 10a and the back-side gel molded body 10b, and the longitudinal direction of the strip tape-shaped seal member 1 formed by stacking them.
- the gel end portions 11 are formed on both ends of the.
- the elongation suppressor 20 is sandwiched between the gel suppressor 20 and the gel suppressor 20 in which the front side gel mold 10a and the back side gel mold 10b are integrated. It surrounds 20.
- the position where the extension suppressing body 20 is sandwiched can be brought closer to a position closer to the front surface side or the back surface side instead of the middle in the thickness direction of the gel molded body 10.
- the gel molded body 10 is composed of a low hardness rubber-like, gel-like, or viscous polymer-like molded body.
- the polymer molded body include silicone gel, acrylic gel, urethane gel, hydrogel and the like. Of these, a silicone gel molded product is preferable because it has low hardness and low compression set.
- the gel molded body 10 has a tensile fracture strength defined by JIS K6251 (ISO37) of 0.05 MPa to 0.15 MPa, and a tensile fracture elongation defined by JIS K6251 (ISO37) of 230 to 400%. It is preferable. By having such physical properties, the gel molded body 10 has shape retention and can be molded into a three-dimensional shape.
- the gel molded body 10 preferably has a compression set of 5% or less measured according to JIS K6262 (ISO815) which is a Japanese industrial standard.
- the compression set is the compression set measured under conditions of 70° C. and 22 hours standing at a compression rate in the range of 50% to 80% where the compression amount is large. Since the compression set of the gel molded body 10 was set to 5% or less, the gel molded body 10 was compressed between the first member 60 and the second member 70 in the direction opposite to the compression direction. A strong elastic force is generated, and the gel molded body 10 has a function of returning to the original shape.
- the needle penetration of the gel molded body 10 is preferably in the range of 60 to 130.
- the penetration is a value measured at 25° C. by a penetration test using a 1/4 cone in accordance with JIS K2220 (ISO2137) as specified in JIS K6249.
- As an index of softness (hardness) there is hardness defined by JIS K6253 (ISO7619), but according to the index by type E defined by JIS K6253 (ISO7619), the hardness of the gel molded body 10 is almost 0. Indicates a value.
- the seal member 1 is incorporated between the first member 60 and the second member 70, the first member 60 or the second member 70 is not deformed or damaged. Moreover, according to the seal member 1, it is possible to exhibit excellent adhesion to the first member 60 and the second member 70.
- the gel molded body 10 Since the gel molded body 10 has the above-mentioned properties, it has an adhesive property that makes it easy to make close contact with the first member 60 and the second member 70. Such adhesiveness may be the same or different on one surface and the other surface of both surfaces of the seal member 1. When they have the same tackiness, both the front and back surfaces can be formed with the gel molded body 10 made of the same material with the elongation suppressing body 20 sandwiched therebetween, and the manufacturing is easy and the manufacturing cost can be kept low. On the other hand, if the front and back surfaces have different adhesiveness, whether the seal member 1 is left on the first member 60 side or the second member 70 side when the first member 60 and the second member 70 are separated from each other. It is possible to use the seal member 1 in advance. The seal member 1 having such a property is convenient when parts are replaced or repaired after the first member 60 and the second member 70 are separated.
- the highly sticky surface of the gel molded body 10 can be realized by applying a pressure sensitive adhesive, an adhesive, a primer, or the like to the surface of the gel molded body 10 to be made highly sticky.
- the surface of the gel molded body 10 having a low tackiness is coated with a release agent or fine powder on the surface of the gel molded body 10 which is to have a low tackiness, or the surface hardness is increased by ultraviolet irradiation or a crosslinking reaction. It can be realized by raising it.
- the extension suppressing body 20 inside the seal member 1 described later close to the surface of the gel molded body 10 on which the adhesiveness is to be lowered, a difference in the adhesiveness of the surface of the gel molded body 10 is obtained.
- the gel molding 10 has a higher penetration and softness on the side away from the elongation suppressor 20, and thus the adhesiveness is enhanced.
- the thickness of the gel molded body 10 existing on the surface of the elongation suppressing body 20 is different, a difference occurs in the extensibility of the surface of the gel molded body 10. On the surface away from the elongation suppressing body 20, the gel molded body 10 becomes relatively easy to stretch and the adhesiveness can be increased.
- the elongation suppressing body 20 has a role of reinforcing the gel molded body 10. If the seal member 1 is composed only of the gel molded body 10, the gel molded body 10 is soft and easily stretches when it is gripped by a hand, and when it is placed on the first member 60 or the second member 70, a predetermined portion is removed. It may stick out. On the other hand, since the seal member 1 contains the expansion suppressing body 20, the expansion of the seal member 1 in the longitudinal direction can be suppressed.
- the extension suppressing member 20 for example, a resin film, a paper, a woven cloth, a non-woven cloth, a mesh-like material (including a mesh-like material), or a sheet-like material such as a metal foil can be used to suppress the expansion of the seal member 1. ..
- the sheet-like material may have a uniform surface, but a sheet having a large number of openings 21 may be used. Since the elongation suppressing body 20 has a large number of openings 21 and the gel forming the gel molded body 10 penetrates into the openings 21, the seal member 1 having a low hardness as a whole can be obtained. In order not to impede the flexibility of the seal member 1, it is preferable to use the thin elongation suppressing body 20.
- a resin film having a thickness of 1 ⁇ m to 10 ⁇ m can be used.
- the openings 21 can be formed in the elongation suppressing body 20 made of a resin film by making a large number of holes.
- the gap between the cloths serves as the opening 21.
- the openings 21 can be made larger as the cloth has coarser meshes and more gaps.
- the mesh of the elongation suppressor 20 which is a net-like material formed by knitting wires, long fibers, short fibers, or twisted yarns made of metal or synthetic resin in the longitudinal and transverse directions has openings 21.
- the material of the wire As the material of the wire, the long fiber, the short fiber or the twisted yarn, in addition to various metals or alloys, synthetic resins such as polyethylene, polyester, polyamide and polyurethane, and natural fibers such as cotton, silk, hemp and wool can be used. ..
- the shape of the opening 21 of the extension suppressing body 20 may be any shape, and may be a square, a rectangle, a rhombus, a triangle, a hexagon, a circle, or the like.
- the expansion suppressing body 20 is a mesh and the shape of the opening 21 thereof becomes longer in the longitudinal direction of the seal member 1, the density of the expansion suppressing body 20 in the longitudinal direction becomes lower than the density in the lateral direction (in other words, For example, the number of constituent members of the extension suppressing body 20 extending in the longitudinal direction is larger than that in the lateral direction), and the seal member 1 that is difficult to extend in the longitudinal direction can be obtained.
- the size of the openings 21 of the net-like material is preferably 10 to 5000 ⁇ m.
- the number of openings 21 is preferably 1 to 500 mesh/2.54 cm, and more preferably 10 to 200 mesh/2.54 cm.
- the line segments 22 forming the lattice form a mesh (opening 21) along the longitudinal direction and the lateral direction of the seal member 1. It is preferable to dispose the elongation suppressor 20 at. The reason is that it is difficult for the line segment 22 constituting the expansion suppressing body 20 formed in the mesh shape or the mesh shape to extend in the longitudinal direction of the seal member 1, and the elongation in the longitudinal direction of the seal member 1 can be made small. Because. In the case where the extension suppressing body 20 is arranged such that the line segment 22 forming the lattice is oblique to the longitudinal direction of the seal member 1 as shown in FIG. 3B with respect to the arrangement of the extension suppressing body 20. The mesh is easily deformed in the longitudinal direction of the seal member 1.
- the cross points (intersection points) of the nets can be knotted, crushed and flattened, or heat-sealed to form a fixed structure. By doing so, it is possible to obtain the seal member 1 in which the mesh is less likely to be displaced and which is more difficult to expand.
- the net-like material may have a net thickness of 20 ⁇ m to 500 ⁇ m, more preferably 10 ⁇ m to 300 ⁇ m. This is because if the net thickness is smaller than 20 ⁇ m, it becomes difficult to handle, and if the net thickness is larger than 500 ⁇ m, it is difficult to apply to a thin device.
- the seal member 1 can be provided with a protective film 30 on at least one of the exposed surfaces of the front and back surfaces to cover the exposed surface of the gel molded body 10 to prevent foreign matter and dust from adhering.
- FIG. 4 shows a cross-sectional view when the front surface side protective film 30a and the back surface side protective film 30b are provided on both front and back surfaces.
- the protective film 30 is provided on only one of the front and back sides (for example, the front side protective film 30a), as shown in FIG. 5, the exposed surface of the gel molded body 10 is protected by another protective film of the seal member 1. It can be covered by overlapping with the surface of 30 (for example, the surface side protective film 30a).
- This form is possible, for example, when a number of seal members 1 are provided in a laminated manner. If the sealing member 1 provided with the protective films 30 on both sides is laminated and provided, the protective films 30 are overlapped with each other, resulting in an increase in volume or waste of one protective film 30. However, such inconvenience can be avoided by providing the protective film 30 by laminating the sealing member 1 provided on only one of the front and back surfaces.
- the protective film 30 on the low adhesive side is easily peeled off, which facilitates the work. That is, when the seal member 1 is attached to the first member 60 (or the second member 70), if the low-adhesive side is attached, the protective film 30 on the opposite side is less likely to peel off. The risk of accidentally peeling off the protective film 30 on the opposite side is reduced. Then, the protective film 30 on the high-adhesive side is peeled off, and the first member 60 and the second member 70 are joined.
- the raw material composition to be the gel molded body 10 is applied onto a resin film or the like as a base material, the elongation suppressing body 20 is placed thereon, and then the raw material composition to be the gel molded body 10 is further placed thereon. Apply. Then, the raw material composition is heated and cured to obtain the seal member 1.
- the elongation suppressing body 20 having the opening 21 the elongation suppressing body 20 is arranged so as to be floated on the base material, and the raw material composition to be the gel molded body 10 is applied on the elongation suppressing body 20 and is passed through the opening 21.
- the seal member 1 can also be manufactured by exuding the raw material composition on the opposite surface.
- the seal member 1 thus obtained has the following properties.
- the tensile breaking strength in the longitudinal direction of the seal member 1 is in the range of 1 to 50 MPa, more preferably 1 to 15 MPa, and the tensile breaking elongation is in the range of 0.1 to 50%, more preferably 0.1 to 25%.
- the inclusion of the elongation suppressor 20 increases these numerical values, making the seal member 1 difficult to stretch, and easy to handle. You can see that is getting better.
- the penetration of the seal member 1 can be set in the range of 60 to 130, and the type E hardness can be set to almost 0.
- the penetration and E hardness of the seal member 1 in the same range as the gel molded body 10, the softness and liquid tightness of the gel molded body 10 should be maintained at the same level as in the case without the elongation suppressing body 20. Is possible.
- the seal member 1 is used by being sandwiched between a frame-shaped housing 60A (first member 60) and a liquid crystal panel 70A (second member 70) in a liquid crystal display device, for example.
- the composite seal structure 2 in which the seal member 1 is sandwiched between the first member 60 and the second member 70 makes the inside sandwiched by the seal member 1 waterproof and dustproof.
- the frame-shaped casing 60A (first member 60) has a structure in which the liquid crystal panel 70A (second member 70) is sandwiched between the front-side casing 60a and the rear-side casing 60b.
- the body 60a and the back side housing 60b are fastened with screws 80. Further, as shown in FIG.
- the seal member 1 is used to surround the display portion of the liquid crystal panel 70A (second member 70) along the frame-shaped housing 60A (first member 60). Since one sealing member 1 has a strip-shaped tape shape and not a frame shape, a plurality of sealing members 1 are used when sandwiched between the first member 60 and the second member 70. ..
- the gel ends 11 of the seal member 1 are overlapped with each other and a plurality of strip tape-shaped seal members 1 are arranged so as to be continuous in the longitudinal direction thereof. Further, at the corner when the seal member 1 is arranged in a frame shape, as shown in FIG. 8, the gel end portions 11 of the two seal members 1 are arranged so as to be orthogonal to each other. At this time, the two sealing members 1 and 1 are arranged so that the overlapping portions 11a and 11a of the gel end portions 11 and 11 overlap each other. Then, the overlapping connecting portions 11b are configured by arranging the overlapping portions 11a, 11a of the two sealing members 1, 1 so as to overlap each other. In this way, by arranging the plurality of seal members 1 so as to form the overlapping connection portion 11b, it is possible to arrange them in a frame shape without a gap.
- the plurality of strip tape-shaped seal members 1 are used,
- the gel end portions 11 of are overlapped with each other.
- the seal member 1 can be arranged in a desired portion without a gap.
- the long side surfaces of the seal member 1 can be arranged adjacent to each other, as shown in FIG. 9.
- the gel end portions 11 of the two sealing members 1 have the same length, when the gel end portions 11 of the two sealing members 1 are superposed on each other, even if the two sealing members 1 are superposed in the longitudinal direction, It is difficult to obtain a portion where the overlapping does not occur even if the overlapping is performed. Therefore, the gel end 11 of the one seal member 1 and the gel end 11 of the other seal member 1 can be overlapped in the same shape.
- the seal member 1 since the gel end portion 11 does not include the elongation suppressing body 20, the gel end portions 11 are easily crushed even when the gel end portions 11 are overlapped with each other, and the first member 60 and the second member 70 sandwich the seal member 1 therebetween. Can be adhered with. Further, in the seal member 1, since the first member 60 and the second member 70 can be brought into close contact with each other with a small compressive load, the influence of the inclusion of the elongation suppressing body 20 on the change of the load value is hardly seen. Further, by using a plurality of seal members 1, it is not necessary to form a frame-shaped casing in a length that makes one round with one seal member, which is preferable in terms of productivity and handleability.
- the seal member 1 is used for a waterproof and dustproof application of a liquid crystal display device having a liquid crystal panel 70A, a solar cell device having a solar panel, a device having a glass panel, a casing of a large-scale device, etc., for those devices. be able to.
