The composite artificial stone table board comprises a surface layer and a base material layer, wherein the surface layer is prepared from raw materials, namely, quartz sand, quartz powder, a curing agent, an accelerant, a solvent, multifunctional epoxy resin, a coupling agent, a pigment and heat-conducting powder; the base material layer is prepared from raw materials, namely, aluminum hydroxide powder, quartz powder, a curing agent, an accelerant, a solvent, multifunctional epoxy resin, a coupling agent and a glass mat. The composite artificial stone table board has the advantages that the table board is high in strength, high in torsion and bending deformation resistance, high in heat conductivity coefficient, quick in heat dissipation, good in heat resistance and flame-retardant, does not age and yellow easily and the like, and the table board is suitable for popularization and application.

Description

technical field [0001] The invention relates to the technical field of processing stone or stone-like materials, in particular to a composite artificial stone countertop and a preparation method thereof. [0002] technical background [0003] Artificial stone slabs are mainly used for kitchen countertops, laboratory countertops, window sills, dining tables, coffee tables, computers, bar counters, commercial plazas, etc. At present, most of the artificial stones used in the market use unsaturated polyester as a binder, and inorganic marble, quartz stone and other scraps are used as aggregates. Due to the low glass transition temperature of unsaturated polyester (<110 ° C =, and When the particles of different particle sizes are mixed with viscous polyester, it is easy to cause uneven mixing, resulting in poor homogeneity of the substrate. Therefore, the molded substrate has problems such as rapid aging, easy deformation, weak impact resistance, and easy cracking or breaking...
