  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a diagram schematically showing the structure of a cloth silicone rubber laminate 1 (front and back double-sided cloth mold) according to the first embodiment of the present invention. This cloth silicone rubber laminate 1 comprises front and back silicone rubber-impregnated fabric layers 5 and 5 'and a silicone rubber layer 7 sandwiched between the two fabric layers.

  The fabric layers 5 and 5 'are impregnated with the silicone rubber 3 including the surface portion on the anti-silicone rubber layer side. The degree of this silicone rubber impregnation does not necessarily have to reach the core of the fibers 6 of the fabric layers 5 and 5 ′. However, the surface of the fiber 6 is impregnated, and the cloth silicone rubber laminate 1 exhibits sufficient waterproofness and water repellency. Therefore, from the viewpoint of the micro structure, the surface of the fabric layer 5 · 5 ′ has a silicone rubber film and exhibits high water repellency.

  As the impregnation method, it is possible to employ insert molding in which a fabric and an uncrosslinked silicone rubber material are set in a molding portion of a mold, and heating and pressure molding are performed. In this case, by pressing and heating, the surface of the fabric away from the silicone rubber material can be covered with the silicone rubber, and the waterproofness of the fabric can be ensured. Furthermore, the silicone rubber layer 7 underlying the fabric layers 5 and 5 'blocks water from entering. It is also possible to employ a method in which liquid silicone rubber is soaked into a fabric and then pressed and cured.

  The color and pattern of the fabric layers 5 and 5 'can be seen from the outside through the impregnated silicone rubber 3 (silicone rubber film). Furthermore, the texture or texture of the fabric can be sensed through the impregnated silicone rubber or silicone rubber film. Here, “texture of fabric” means “visual and tactile feeling of fabric. Surface texture”. The “texture of fabric” is “texture of fabric, touch, bulge, beam, strain” and the like. Even when the laminate is pressed using a mold having a smooth surface, unevenness of the surface of the fabric layers 5 and 5 'is generated, and the original feel of the fabric can be obtained.

  The type and weaving method of the fabric are not limited. Denim and cotton (patterns; Japanese patterns (Japanese traditional patterns, etc.) can be used, etc. The type, color, and pattern of the fabric may be different on the front and back sides.

The thickness of the fabric is not limited, but from the standpoint of productivity in the impregnation process, about 0.1 mm to 0.4 mm is standard. If the mechanical properties of the fabric are the same on the front and back, a laminate with less warpage can be obtained. Note that the front and back fabric layers 5 and 5 'themselves may be composed of two or more types of fabrics.

  Silicone rubber is soft, and appropriate flexibility can be realized by selecting the thickness. Moreover, since it does not contain various chemicals like other synthetic rubbers, it is excellent in safety to the human body. Uncolored silicone rubber is usually translucent and white. Pigments and phosphorescent pigments can be added to the silicone rubber. For example, in the form in which the end surface (cut surface or the like) of the silicone rubber layer is visible, the end surface can be particularly illuminated.

  Although the kind of silicone rubber of the silicone rubber layer 7 is not particularly limited. The thickness is, for example, about 0.5 mm to 2 mm depending on the application.

  FIG. 2 is a diagram schematically showing the structure of a cloth silicone rubber laminate (single-sided cloth mold) according to the second embodiment of the present invention. This fabric silicone rubber laminate 11 is composed of a fabric layer 15 on the front side and a silicone rubber layer 17 therebelow. The fabric layer 15 is impregnated with silicone rubber 13. This single-sided fabric-type laminate 11 tends to warp in a form in which the fabric layer 15 is convex, and is not suitable for use in a natural and flat form. However, it is suitable for a ring-shaped handle grip or an ankle winding belt. The “ankle winding belt” is a belt-like belt that is wound so that the bottom of the pants is not opened when riding a bicycle or a motorcycle.

  FIG. 3 is a diagram schematically showing the structure of a silicone rubber-impregnated fabric (front and back double-sided fabric type) according to the third embodiment of the present invention. The silicone rubber-impregnated fabric 21 is composed of front and back fabric layers 25 and 25 '. The fabric layers 25 and 25 ′ are impregnated with silicone rubber 23 and 23 ′. This silicone rubber-impregnated fabric 21 is thinner and more flexible than the fabric silicone rubber laminate of the first and second embodiments. In the first embodiment, when all the silicone rubber layers are impregnated into the fabric layer and absorbed, the silicone rubber-impregnated fabric (front and back double-sided fabric type) according to the third embodiment is obtained. Alternatively, the cloth may be cured after being impregnated with liquid silicone rubber.

  FIG. 4 is a diagram schematically showing the structure of a silicone rubber-impregnated fabric (single-sided fabric type) according to the fourth embodiment of the present invention. The silicone rubber-impregnated fabric 31 is made of a fabric layer 35 impregnated with silicone rubber 33/33 ′. The silicone rubber-impregnated fabric 31 can be made thinner.

  FIG. 5 is a flowchart showing a method for producing a cloth silicone rubber laminate according to an embodiment of the present invention. First, a cloth and an uncrosslinked silicone rubber material (with a crosslinking agent) are set in the mold (S1). Then, the entire mold is heated and pressurized, and the silicone rubber is impregnated into the fabric and crosslinked and cured (S2). As an example, the heating temperature at this time is 160 ° C. to 180 ° C., the pressure is 50 kgf / mm 2 to 200 kgf / mm 2, and the time is 10 minutes to 15 minutes. Thereafter, the laminate is released (S3), and if necessary, surface roughening such as cutting, sewing, printing, blasting and laser is performed (S4) to obtain a product.

  FIG. 6 is a diagram schematically showing the structure of a fabric silicone rubber laminate (dish-covered, front and back double-sided fabric type and with a convex pattern) according to the fifth embodiment of the present invention. In the fifth embodiment, as shown in the plan view of FIG. 6 (A), the whole is a circular dish 51 (placement mat). And the star-bowl pattern 55 (refer the enlarged view of (B)) and the dot pattern 57 are formed in the form which rises from the ground part 53 of the surface.

  As shown in FIG. 6 (C), the cross-sectional structure of the dish-laying 51 is basically a double-sided cloth-type silicone rubber laminate, with both front and back silicone rubber-impregnated fabric layers 63 and 63 'and both fabric layers. And a silicone rubber layer 65 sandwiched between the two. And the convex part (pattern) 61 is formed in the front and back. The fabric layer 63 protrudes to a position immediately below the surface at the central portion 61d of the convex portion 61, but does not reach the surface at the corner portion 61b of the convex portion 61. This is because the fabric layers 63 and 63 ′ could not follow the corners of the concave portions of the molding die. An edge portion 61c made of silicone rubber that has passed through (exuded from) the fabric 63 is present at the corner portion 61b of the convex portion 61.

  Therefore, as seen in FIG. (B), the color of the fabric layer 63 is seen dark at the central part 61d of the convex part 61, whereas the color of the silicone rubber of the edge part 61c is won at the corner 61b, The color of the fabric layer 63 is lighter. Such a change in color tone creates a taste that cannot be produced by printing. That is, at the edge of the convex part (or concave part), the thickness of the silicone rubber film changes and the hue changes, and a new design pattern is expressed.

  Depending on the followability of the fabric to the digging of the mold (uneven design design) and the angle and depth of the digging shape of the mold, the fabric is applied to the corner of the mold digging (corner). Permeated silicone rubber is filled, and contrast is provided as a pattern on the exterior, and a unique design can be obtained. In this embodiment, the fabric is cotton.

  In the dish bed 51, due to the high friction coefficient characteristic of silicone rubber, the table on which it is placed and the tableware on it are difficult to slip. Therefore, it is suitable for people who can use only one hand.

  FIG. 7 is a cross-sectional view schematically showing the structure of the cloth silicone rubber laminate (the outer surface also has a cloth layer) according to the sixth embodiment of the present invention. In this embodiment, in addition to the fabric layers 75 and 75 ′ covering the front and back of the silicone rubber layer 77, the side surface (end surface) is also provided with a fabric layer 75 ″. In this embodiment, the side surface is also preferable because the design treatment of the fabric layer appears. The fabric layer 75 ″ on the side surface is formed by winding the fabric and cutting the outer periphery 79 after forming. Also good.

  FIG. 8 is a view of a handle grip 81 to which a cloth silicone rubber laminate (single-sided cloth type) according to the second embodiment of the present invention is applied, (A) is an overall assembly view, and (B) is a handle grip body. 83 is a plan view of FIG. 83. FIG. The handle grip 81 is attached to an end portion of a handle 89 of a bicycle or a motorcycle.

  The main body 83 of the handle grip 81 has the same form as the single-sided cloth-type cloth silicone rubber laminate 11 (see FIG. 2), and the cloth layer is a denim fabric. The overall thickness is, for example, about 2 to 3 mm. The grip body 83 is rounded to a diameter of about 20 mm to 30 mm with a denim fabric layer (silicone rubber impregnation) on the outside and a silicone rubber layer on the inside. The length is about 100 mm to 150 mm. A cap 87 is attached to the end.

  As shown in FIG. 8B, the grip body 83 in this example has a large number of string holes 83b at both ends in the width direction. The string hole 83b is rounded through a string 85. A double-sided tape 84 is affixed to the center portion inside the grip body 83. This double-sided tape 84 is fixed to a handle 89 such as a bicycle.

  This type of handle grip 81 may be attached to a round handle of an automobile (four wheels) in addition to a handle of a two-wheeled vehicle. Moreover, it can also be used as a grip of a golf club or a tennis racket, or a grip of a shift lever of an automobile. The characteristics of the material of the present invention having both waterproofness, high friction coefficient, and design properties can be fully exhibited.

Next, a specific example of a method for manufacturing the handle grip body 83 will be described.
