Abstract

The invention provides a novel resin type artificial stone prepared from, by weight parts, 20-60 parts of polyurethane modified unsaturated polyester / phase change energy storage microcapsule compositematerial, 50-90 parts of inorganic filler, 10-20 parts of curing agent, 10-15 parts of accelerator, 5-10 parts of coupling agent, 1-5 parts of ultraviolet absorber, and 1-10 parts of inorganic pigment. In the prepared artificial stone, the polyurethane modified unsaturated polyester / phase change energy storage microcapsule composite material is added, which effectively increases an interfacial force between the inorganic filler and the unsaturated polyester, improves the toughness of the unsaturated polyester composite material and reduces the curing shrinkage rate. The obtained composite material has good thermal insulation performance; the ultraviolet absorbent is added to prevent the aging caused by the artificial stone being irradiated by ultraviolet rays, and the service life of theartificial stone is improved.

Description

technical field [0001] The invention relates to the technical field of artificial stone, in particular to a novel resin type artificial stone. Background technique [0002] Resin-based artificial stone is developed in recent years, using resin as the matrix, and then adding fillers of different fineness, color pastes of different colors and additives according to a certain proportion, mixed with raw materials, through stirring, casting, gelling, curing, etc. A new type of building decoration material made by a series of technological processes. At present, artificial stone products on the market include ornate stone, Jieli stone, Keli stone and so on. Although the product names of each company are different, the ingredients are actually the same and can be collectively referred to as "artificial stone". It is customary abroad to refer to this type of product as "Solid Surface materail". Because resin-based artificial stone not only has the texture of natural marble and th...
