▎ 摘  要

NOVELTY - A lightweight quartz stone plate comprises 55-60 %mass, preferably 60 %mass quartz powder with a particle size of 1-5 mum, 15-20 %mass, preferably 15 %mass fly ash microspheres, 10-20 %mass, preferably 15 %mass unsaturated polyester resin, 1-5 %mass, preferably 2 %mass glass fiber powder, 1-5 %mass, preferably 3 %mass nano graphene powder, 0.1-2 %mass, preferably 0.5 %mass accelerator, 1-5 %mass, preferably 1.5 %mass curing agent and 1-5 %mass, preferably 3 %mass coupling agent. The sum of the above raw material mass percentages is 100%. The bulk density of the fly ash microspheres is 0.6-0.7 g/cm3. USE - Lightweight quartz stone plate e.g. double-layer composite plate. ADVANTAGE - The light quartz stone plate has high hardness, wear resistance and high temperature resistance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a preparation of the lightweight quartz stone plate.
