Problems solved by technology

[0004] Artificial marble is mainly composed of binders and inorganic fillers. At present, there are many kinds of binders and inorganic fillers used in artificial marble. However, the inventors have found in practice that existing artificial marbles still have aging problems and surface defects. Low hardness, poor wear resistance, poor mechanical properties, easy to cause deformation, fracture and poor gloss of the product, and the product has extremely low fire resistance

Abstract

The invention discloses a high-performance artificial marble. The high-performance artificial marble comprises the following raw materials in parts by weight: 10-15 parts of matrix resin, 50-70 partsof a filler, 0.6-0.8 parts of a curing agent, 0.2-0.4 parts of an accelerator, 4-5 parts of a pigment, and 10-20 parts of a flame retardant. The artificial marble of the invention mainly uses unsaturated polyester resin, modified epoxy resin and silicone modified polyurethane resin as binders, and uses marble waste rock powder, modified nickel slag and modified waste glass as the filler. various pigments, the curing agents and the accelerators are added, a stone product is made by stirring, forming, solidifying and polishing, the comprehensive mechanical properties of artificial marble can begreatly improved, the chance of cracks is effectively reduced, the wearing is not easily generated, and the obtained artificial marble has better gloss so as to achieve the comfortable visual experience of the human body and the space decoration effect without light pollution; the flame retardant performance is superior, and the comprehensive performance of the artificial marble board is improved.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a high-performance artificial marble. Background technique [0002] In the modern building material decoration market, natural marble is widely used in interior decoration because of its elegance, beauty, and good decorative effects. However, natural marble also has its shortcomings and shortcomings. First, because natural marble is a kind of ore resource, its origin is not many in the world, and its output is limited; Caused the difficulty of transportation and daily maintenance. These shortcomings greatly limit the application of natural marble. Therefore, finding a substitute for natural marble has become an extremely important issue. [0003] Artificial marble can not only achieve the texture and beauty of natural marble, but also overcome the shortcomings of uneven color and more cracks in natural marble. In addition, it has the advantages of being easy to sha...
