JPS60155782A - Floor covering material comprising composite material of rubber elastomer and fiber - Google Patents

Abstract

PURPOSE:To obtain a floor covering material having good touch, low water absorption properties, and improved functional properties, by molding a blend of rubber elastomer and fibers, subjecting it to surface polishing, and buffing. CONSTITUTION:Rubber elastomer (e.g., natural rubber, SBR, etc.) is blended with fibers such as cotton, wool, nylon, etc. to give a blend, which is kneaded and press molded. The surface is polished smoothly, buffed by wire, and the surface is finished in napped state.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a composite of the rubber elastomer 1 and the fibers 2, which has a raised surface by surface polishing and wire buffing a molded product composed of the rubber elastomer 1 and the fibers 2. related to the manufacture of flooring materials.

In general, flooring materials made using rubber elastomer 1 or m-fiber 2 require constant drying because the rubber elastomer 1 product alone has a cold surface, and the fiber m2 product alone has a sticky surface when wet. Yes, there are restrictions on where it can be used. In the case of a product with rubber elastomer 1 and fiber 2, the working process is complicated and the cost is high, and the water-wet state is the same as with fiber 2 alone.

In the present invention, in order to improve such drawbacks, the rubber elastomer 1 and the fiber [2] are kneaded, sheeted, press-molded, surface polished, and wire buffed, which are sequentially performed to create a material with a brushed surface that feels good to the touch. This provides a flooring material with low water absorption and excellent functionality.

The manufacturing process of the present invention will be explained below based on one example. The manufacturing process of a 3 mm thick flooring material is as follows: 1 part of rubber elastomer mixed with 100 parts of rubber elastomer mixed with 4 parts of fiber. 20 parts of I2 were kneaded, sheeted to a thickness of 1.4 mm, cut into a mold shape, three cut sheets were placed in a mold with a depth of 4 mm, press molded, and the surface was polished 2 times.
The material is rotated to make the thickness even, and finally wire buffed to give the surface a brushed appearance to create a 3mm thick flooring material. Examples of rubber elastomer blending and the contents of the composition are described in Example 1.

(Example 1) For 100 parts of rubber elastomer (natural rubber, SBR, BR), 80 parts of white carbon, 40 parts of calcium carbonate, 10 parts of petroleum resin, other sulfur, accelerator, zinc white, Mix and knead lubricant, wax, activator, etc.

Next, in Example 2, a press example for a physical property test sample of the rubber elastomer-1 blend and physical property values are described.

(Example 2) Two sheets of rubber elastomer-1 compound sheeted to a thickness of 1.2 m+a were placed in a mold with a depth of 2.3 mm, and press molding was performed at a temperature of 150 to 160°C for 8 to 10 minutes. example.

Next, to briefly explain the fiber m2 material used in the present invention, cotton, wool, nylon, Tetron, etc. can be used, but in one embodiment, nylon fiber m2 with good heat resistance, abrasion resistance, water resistance, etc. By using this material, it can fully fulfill its function as a flooring material.

Finally, the polishing, wire buffing, and hanging in the present invention will be explained based on the drawings. Figure 1 shows the molded state immediately after pressing, and Figure 2 is a cross-sectional view of Figure 1. Figure 3 shows the state in which the fibers 2 and 2 are blended.
Figure 4 shows the surface polished using emery abrasive paper, and Figure 4 shows the surface in Figure 3 wire buffed.
The fiber 2 is shown in a raised state.

As described above, the present invention makes it possible to easily manufacture a flooring material made of a functionally excellent composite of rubber elastomer 1 and fiber 2.
