Abstract:
Artificial silica marble according to the present invention comprises a base material and a line pattern part and has an amorphous pattern of a lumped pattern on the cross section of the marble by the partition of the line pattern part. The line pattern part is formed by a fine line forming a spider silk or a mesh, and the fine line has a thickness of 50-500 micrometers based on the cross section of the marble.
Abstract:
A chip composition for a native stone according to the present invention comprises (A) 75-82 wt% of a silica containing compound and (B) 18-25 wt% of an unsaturated polyester resin, and comprises (C) 0.5-4.5 parts by weight of a pigment, pearl, or a compound of the same for 100 parts by weight of (B) the unsaturated polyester resin, has a multicolor layer, and prevents the phenomenon of the surface roughness reduced around the chip during polishing cause by the difference between surface hardness when applied to a native stone.
Abstract:
PURPOSE: Artificial marble is provided to have natural stone texture in a bright plate and a light accumulation effect in a dark plate by containing an unsaturated polyester resin, natural stone particles, inorganic filler, an organic/inorganic pigment, and a light accumulation chip at an optimum ratio. CONSTITUTION: Artificial marble contains 5-15wt% of unsaturated polyester resin, 75-92wt% of silica-containing compound, and 3-10wt% of amorphous light accumulation chip. The distribution area of the light accumulation chip on every cross section of the artificial marble is 3-10% of the cross section area of the artificial marble. The artificial marble additionally contains 0.01-1 parts by weight of organic/inorganic pigment for 100 parts by weight of the composition containing the unsaturated polyester resin, the silica-containing compound, and the light accumulation chip. The average particle diameter of the light accumulation chip is 0.1-5.6 mm.
Abstract:
PURPOSE: An artificial marble has natural stone texture and part phosphorescent property by including the optimal proportion of a phosphorescent amorphous pattern part using a non-phosphorescent material and a phosphorescent pigment. CONSTITUTION: An artificial marble includes 70-95 weight% of a non- phosphorescent material (I) and 5-30 weight% of a phosphorescent amorphous pattern part (II). The non- phosphorescent material (I) includes an unsaturated polyester resin (A), a silica-containing compound (B), and organic/inorganic pigments (C). The phosphorescent amorphous pattern part (II) includes an unsaturated polyester resin (A), a silica-containing compound (B), and a phosphorescent pigment (D). The total surface area of the phosphorescent amorphous pattern part (II) is 5-30% of the artificial marble surface area. The non- phosphorescent material (I) has 7-10 weight% the unsaturated polyester resin (A), organic/inorganic pigments (C) of 1-1 parts by weight against a non- phosphorescent material composition 100.0 having 90-93 weight% of a compound containing silica (B). The phosphorescent amorphous pattern part (II) includes 7-10 weight% of an unsaturated polyester resin (A), 85-91 weight% of a compound containing silica and 2-5 weight% of the phosphorescent pigment.
Abstract:
PURPOSE: A marble chip manufacturing method, a marble chip manufactured by the method, and artificial marble including the marble chip are provided to manufacture artificial marble with specific patterns by freely controlling the shape, color, and material of marble chips. CONSTITUTION: A marble chip manufacturing method is as follows. A composition of marble chips is poured into a mold after vacuum-defoaming, wherein the marble chip composition is composed of a binder and reactive monomer at a weight ratio of 1:1~9:1. The marble chip composition is cured and separated from the mold.
