Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing artificial stone technologies face challenges in replicating natural stone-like patterns and textures, particularly in uniformly distributing transparent chips within the matrix resin to prevent 'breaking' phenomena and achieving high-quality, natural metal-like appearances.
Innovation Solution
Development of transparent chips with a natural metal-like texture, coated with colored materials like metal powders, and a specific gravity lower than the matrix resin, which are uniformly distributed using a transparent resin with a curing agent, ensuring compatibility and preventing 'breaking' phenomena.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If transparent chips with higher specific gravity are used, then the chips can be uniformly distributed in the matrix resin, but the 'breaking' phenomenon occurs between chips and matrix resin
Solution Approach 1:
The patent changes the specific gravity parameter of the transparent chips by coating them with materials having specific gravity between 2.0-2.65, which is lower than the matrix resin's specific gravity (2.2-2.8). This parameter adjustment enables uniform distribution while preventing the breaking phenomenon between chips and matrix resin.
2Manufacturing precision
If natural stone-like patterns are attempted to be imparted to artificial stone, then the appearance quality improves, but it is very difficult to prepare natural-like transparent chips
Solution Approach 1:
The patent creates composite transparent chips by coating silica-containing transparent chips with colored materials (metal powders such as gold, silver, copper, aluminum, nickel). This composite structure achieves natural metal-like textures and patterns while maintaining the manufacturing feasibility of transparent chips.
3Manufacturing precision
If transparent chips are used to create natural stone-like texture, then the appearance quality improves, but it is very difficult to uniformly distribute the transparent chips in the matrix resin
Solution Approach 1:
The patent adjusts the specific gravity parameter of transparent chips to fall within 2.0-2.65, which is lower than the matrix resin's specific gravity (2.2-2.8). This parameter change ensures uniform distribution of chips throughout the matrix resin while maintaining natural stone-like texture appearance.

AI summary
The present invention provides transparent chips with natural metal-like texture by coating silica-containing transparent chips with colored material, such as a metal powder, in a transparent resin as a base resin. The present invention also provides artificial stone with natural metal-like texture and patterns by mixing the colored material coated transparent chips and inorganic filler with a matrix resin. The artificial stone of the present invention can be prepared by mixing about 4 to about 24 parts by weight of inorganic filler and about 0.1 to about 5.0 parts by weight of the colored material coated transparent chips, per about 1 part by weight of the matrix resin. The colored material coated transparent chips can have a specific gravity of about 2.0 to about 2.65, while the matrix resin can have a specific gravity of about 2.2 to about 2.8, and the specific gravity of the transparent chips can be equal to or lower than the specific gravity of the matrix resin in promote uniform distribution of the transparent chips in the matrix resin.
