Abstract

PURPOSE: To effectively provide the integrity of a restricting material with rubber by integrating a laminating material with rubber, polymer or bondable polymer in the state that the cut section cut in the same direction as the pressurizing surface is exposed. CONSTITUTION: Rubbers are pressed to both the surfaces of a restricting material 1 in which woven fabric of natural fiber, artificial fiber, metal fiber or glass fiber or nonwoven fabric is stickiness pretreated to form a laminating material 3. Predetermined number of the materials 3 are superposed in response to the using purpose to form a laminated material, and when the laminated material is pressurized, the rubbers are rigidly intruded into the material 1, and the air in the material 1 is extruded to enhance the degree of adhesion to increase the rigidity. Accordingly, the material 1 can be intruded by a large pressurizing force even if a material in which the adhesive properties with the rubber is not good and which has high Young's modulus such as Kevlar is used. Therefore, the laminated material is cut in a predetermined width in the same direction at the pressurizing surface.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multilayer rubber material which can be used as a cushioning material and a slip preventing material for road surface layers such as roads and bridges and general structures, and a method for producing the same.

[0002]

2. Description of the Related Art There is a multi-layered rubber material obtained by laminating a laminate material in which a restraining material such as a fiber is embedded and bonded in rubber. In such a rubber material, the thickness and the laminating amount of the laminate material are changed according to the purpose of use. According to the purpose of use, the method of manufacturing this multi-layered rubber material is to stack rubber on both sides of the constraining material such as cloth or iron plate and roll it with rollers to press the rubber on both sides of the constraining material to make it integral. To make a laminated material.

A multi-layer rubber material laminated in a desired layer can be obtained by repeating the steps of stacking the laminated materials and rolling them again with a roller and performing vulcanization.

[0004]

When the multi-layered rubber material laminated in this way is used as a road surface material, there is a problem that the friction coefficient is drastically reduced when the rubber surface becomes wet during rainfall or snowfall. is there. Therefore, in order to increase the frictional resistance of the surface, processing such as forming a groove on the surface may be performed, but this is not a fundamental solution.

[0005]

Therefore, according to the present invention, a predetermined number of laminated materials formed by pressing rubber on both sides of a restraint member made of woven or non-woven fabric such as natural fiber, artificial fiber, metal fiber, glass fiber, etc. It is characterized in that the laminated laminated materials are integrated with rubber or a selected rubber such as a polymer or a bondable polymer in a state where the cut surface obtained by cutting the laminated material in the same direction as the pressing surface is exposed.

[0006]

According to the above construction, the binding material and the rubber are surely integrated with each other, the desired elastic characteristics can be obtained, and the cut surface of the binding material is exposed in the state of flocking. It can be used as a cushioning material or anti-slip material in the field.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of a multi-layer rubber material, FIG. 2 is an explanatory view showing a rolling process, FIG.
Is an explanatory view of pressing the laminated material, FIG. 5 is an explanatory view of cutting the laminated material, and FIG. 6 is an explanatory view of a state where the laminated material, rubber and the like are installed in a mold, and in the drawing, 1 is a natural material. fiber,
This is a restraint material that has been subjected to pre-bonding treatment with woven cloth or non-woven cloth such as artificial fiber, metal fiber, glass fiber, etc. The rubber material 2 is pressed against both sides of the restraint material 1 to form the laminate material 3.

A predetermined number of the laminated materials 3 are stacked according to the purpose of use to form a laminated material 4, and the laminated material 4 is pressed by a pressurizer 5. For example, in the case of laminated material with 15 layers, 50 kg /
Pressurize at about cm ² . By this pressurization, the rubber 2 firmly bites into the restraint material 1 and pushes out the air in the restraint material 1 to make it a rigid body in a state of high adhesion.

Therefore, even if a material having a high Young's modulus such as Kepler, which does not have good adhesiveness with the rubber 2, is used as the restraint material 1, it can be physically engulfed by a large pressing force. Therefore, the laminated material 4 is cut along the pressing surface in the same direction with a predetermined width. Since the laminated material 4 is rather rigid as described above during this cutting, it can be cut by a cutting machine 5 such as a cutter, a hydraulic cutter or a laser used for cutting a normal rigid body.

As shown in FIG. 6, the laminated material 4 cut into a predetermined width is placed in contact with the wall surface of the mold 6 so that the cut surface is exposed. A rubber 7 selected according to the purpose from among adhesively attachable polymers or the like is press-fitted to cover a surface other than the cut surface which is brought into contact with the wall surface of the mold 6, or as shown in FIG. The rubber 7 is pressed against the front surface or the front and back surfaces and the back surface are covered with the rubber 7 to be integrated, and the surface covered with the rubber is appropriately determined according to the purpose of use.

After that, vulcanization is performed to obtain the desired multilayer rubber material 8
Is obtained. In the above structure, the restraint material can be exposed at an arbitrary interval by changing the thickness of the laminate material or changing the stacking interval.
An example of using the thus obtained multi-layered rubber material will be described below. The first example is a case where it is used as a road surface material, and rubber is laid on both sides of a restraint material such as a cloth or an iron plate as in the conventional case.
By rolling it with rollers, the rubber is pressed against both sides of the restraint material to form a laminated material, and the multilayer rubber material is arranged on one side of this laminated material in a plane with the cut side up, and then added. By performing vulcanization, a road surface layer material covered with the cut surface of the multilayer rubber material can be obtained.

The second example, as shown in FIG. 7, is also a case where it is also used as a road surface layer material, and rubber is laid on both sides of a binding material such as cloth or iron plate and rolled by rollers as in the conventional case. By pressing rubber against both sides of the restraint material to form a laminated material, the laminated rubber material 9 is arranged on one surface of the laminated material 9 in a ridge shape with the cut surface facing upward, and then vulcanized. It is possible to obtain a road surface material in which the cross-sectional shape of the multi-layered rubber material is a ridge and which has irregularities.

[0013]

According to the present invention described in detail above, a predetermined number of laminated materials formed by pressing rubber on both sides of a restraint material are laminated to form a laminated material, and the laminated material is applied in a predetermined direction on the pressing surface in the same direction. Cut with a width, place this laminated material in contact with the wall surface of the mold so that the cut surface is exposed, and press fit the above rubber or selected rubber such as polymer or adhesive polymer into the mold. By covering the surfaces other than the cut surface that is brought into contact with the wall surface of the mold described above and performing vulcanization to make a multilayer rubber material, the integrity of the restraint material and the rubber is ensured and the desired elasticity is obtained. Since the cut surface of the restraint material is exposed in the state of flocking, it can be used as a cushioning material or anti-slip material in various fields.

Therefore, when the cut surface of this multilayer rubber material is used as the road surface material, the surrounding rubber exerts a cushioning effect on the frictional force of a passing vehicle and suppresses the generation of concentrated loads. Therefore, there is an effect of suppressing the occurrence of wear, and a restraint material exerts a frictional force against slip, so that a slip accident can be prevented even in a wet state.

Further, when a load is applied to the frozen road surface, it is elastically deformed, so that the ice on the surface is cracked and a slip accident can be prevented.
