Abstract

PURPOSE:To permit the manufacture of a geometrically patterned multi-color tile by using a simple mold by a method in which various color sheets of a rubber elastomer or a thermoplastic resin are integrally molded in molds with a geometrically patterned uneven form and the surface sheet of the sheets so molded is smoothly polished. CONSTITUTION:A round sheet 3 is set on the projection 6 of a mold 1, a roundly punched sheet 4 is then set in such a way as to avoid lapping with the sheet 3, and a flat sheet 5 is set over them. They are molded by press molding method to obtain a tile. The surface of the tile so molded is polished two times and further polished precisely, washed with water, dried, and waxed.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing multicolored geometric tiles. Generally, when manufacturing tiles with multicolored geometric patterns using rubber elastomer or thermoplastic resin, the structure of the mold is complicated or the molding is performed in multiple stages. After simultaneous press molding with a mold, it is possible to manufacture multi-colored geometric tiles by polishing in the post-process. The present invention is composed of many types of sheets, and since several types of sheets are used for the multicolored geometric pattern of tile group 11i71, colorful and weather-resistant rubber elastomer or thermoplastic resin is used. Since the remaining sheet is used for the entire back side 2 of the tile and a part of the tile front side 1, rubber elastomer or thermoplastic resin is used, which has good adhesion to the base, water resistance, and weather resistance. .

The formulation examples, physical property data, and manufacturing process of the present invention will be explained below.The tile surface 1 has weather resistance, i.e.
! In order to provide ozone one-color stability and to freely select the color tone and product hardness, rubber elastomers or thermoplastic resins such as C8M (chlorosulfonated polyethylene), SBR (styrene butanoene rubber), and EPR (
(ethylene propylene rubber), CPE (chlorinated polyethylene), UR (urethane rubber), etc. are used. In Example 1, formulation examples and physical property data for tile surface 1 are described.

(Example 1) For 50 parts of chlorosulfonated polyethylene, 30 parts of chlorinated polyethylene, and 20 parts of styrene-butanoene rubber,
70 parts of calcium carbonate, 20 parts of hard clay, 15 parts of titanium pigment, 5 parts of magnesium oxide, 3 parts of zinc white, 1 part of sulfur.
After mixing and kneading 2 parts of V, 3 parts of accelerator, its lubricant, anti-aging agent, pigment, etc., sheeting is performed after 1.2 mm of original music.

DuPont Co., Ltd.), CPE is Gisolac 104 (Osaka Soda Co., Ltd.), SBR is Turprene 1205 (Asahi Kasei Co., Ltd.), and the lubricant is stearic acid.

Next, the back side 2 of the tile is made of rubber elastomer or thermoplastic resin to provide weather resistance, adhesiveness, and water resistance.
8M (chlorosulfonated polyethylene), CR (chloroprene rubber), 5BR (styrene rubber), E
PR (ethylene propylene rubber) or the like is used. In Example 2, formulation examples and physical property data for the back side 2 of the tile are described.

(Example 2) Chlorosulfonated polyethylene 7 (10 parts of IL ethylene propylene rubber, 10 parts of styrene butadiene rubber, 10 parts of chloroprene rubber, 10 parts of carbonate pigment, 5 parts of magnesium oxide, 2 parts of zinc white, 2 parts of sulfur) 2 parts accelerator, other lubricants, anti-aging agents.

After mixing and kneading pigments, etc., sheeting is performed to a thickness of about 3.21 parts m.

Next, to explain the manufacturing process of the present invention, various types of sheets are mixed and kneaded, sheeted and cut into a certain thickness and shape, and placed in a mold with uneven geometry and horizontal pattern. Fill part or the entire surface, then prepare the sheet that will become the back side 2 of the tile and part of the front side 1 of the tile, perform press molding, and then polish the formed tile surface 1 using a belt Sangu machine using a 4$32 AA machine. Attach abrasive paper and polish twice, then surface polish once.
Do not turn on the light, wash with water, dry, and then hang it up.

The method of filling a mold according to the present invention will be explained based on the drawings. Fig. 1 shows an example of the preparation sheet and the shape of the mold. In Figs. 6, then the sheet 4 cut into circular shapes is charged so that the circular sheet 3 and the sheet 4 cut into circular holes do not overlap according to the shape of the mold, and then the flat sheet 5 is charged. Figure 4 shows the state of the tile immediately after being press-molded.
In FIG. 5, various arrangement states of the sheets are shown in the c-d line sectional view in FIG. 4, and in FIG.
The color arrangement upon completion of polishing is shown based on a cross-sectional view.

Next, as an example of the manufacturing method of the present invention, 3m16
The production process for thick multicolored geometric pattern tiles will be explained based on the drawings. In the mold dimensions in Fig. 1, the depth of the recessed part 7 is 4.3 am, and the depth of the convex part 6 is 3.3161+.
1, the circular sheet thickness 3 and the circularly cut flat sheet 4 are each 1.2 mm thick, and the flat sheet 4 is 3.2 m thick.
The ring-thick material was put into the condition shown in Figure 3 and press-molded to obtain a 4.3mm thick tile in the condition shown in Figure 5.Then, the surface was polished to 3.5m + 6 thickness for the first time, and then l @ second time, make it 3.1L 1m thick, and finally perform fine polishing 3. O
Finish to a thickness of mm.

As described above, the present invention makes it possible to manufacture multicolored geometric pattern tiles with characteristics such as elasticity, anti-slip, and shock absorption by press-molding with a simple mold and then surface polishing. .
