Composite artificial stone table board and preparation method thereof

The invention discloses a composite artificial stone table board and a preparation method thereof. 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.
