Method for producing marble

Abstract

The present invention relates to a method for manufacturing marble, the method is characterized in that the resin combination used for manufacturing artificial marble is shaped to produce artificial marble, wherein the resin combination used for manufacturing artificial marble is obtained by mixing lamellar pattern materials having minuteness concavo convex marks on the surface thereof with matrix resin. According to the invention, the pattern materials mix with matrix resin in a dense condition and the physical property of which will not reduce due to the anchoring action of the concavo convex marks on the surface of the minuteness concavo convex marks pattern materials. Furthermore, pattern materials do not attach to the metal molds when the artificial marble is shaped, due to the minuteness concavo convex marks on the surface of the pattern materials.

Description

technical field [0001] The present invention relates to a method for producing artificial marble for furniture parts, building materials, and the like. Background technique [0002] In the past, marble was manufactured with resin compositions for pattern materials containing colorants and resins to attach Figure 4 The mode of (a) is molded with the fully solidified patterned body 3, after pulverizing this fully solidified patterned body 3 with a pulverizer, it is shaped into an attached Figure 4 (b) The flaky pattern material 1 is mixed with the matrix resin (in this case, a filler, a curing agent, etc.) to obtain a resin mixture for the manufacture of artificial marble. artificial marble. [0003] However, in the past, the fully cured pattern material molded body 3 was formed by using a resin composition for pattern material production containing a coloring agent and resin, and the completely cured pattern material molded body 3 was pulverized by a pulverizer and formed i...

Problems solved by technology

[0003] However, in the past, the fully cured pattern material molded body 3 was formed by using a resin composition for pattern material production containing a coloring agent and resin, and the completely cured pattern material molded body 3 was pulverized by a pulverizer and formed into a sheet-like pattern. material, so the surface roughness of the flake-shaped pattern material 1 after forming is Ra=0.1 μm or less, such as Figure 4 As shown in (c), the pattern material 1 surface is in a mirror state, resulting in low physical properties such as poor interface adhesion between the pattern material 1 and the matrix resin, for example, cracks are prone to occur, and once the sheet-like pattern material 1 surface is in a mirror state, it is easy to Adhering to the surface of the metal mold during molding, the product pattern will be deviated and there will be problems with poor appearance
