Abstract

The invention discloses an artificial quartzite plate. The artificial quartzite plate comprises, by mass, 6-8% of cast stone of 6-8 meshes, 2-4% of nanometer silicon carbide of 8-10 meshes, 2-4% of alumina crystals of 16-30 meshes, 10-11% of quartz sand of 10-20 meshes, 10-12% of quartz sand of 20-40 meshes, 12-14% of quartz sand of 40-70 meshes, 12-14% of quartz sand of 70-140 meshes, 24-26% of quartz sand of 300-600 meshes, 8.5-9.5% of unsaturated polyester resin, 0.7-0.8% of a curing agent and 0.8-1.0% of a coupling agent. The artificial quartzite plate has the characteristics of high hardness, high toughness, high temperature resistance and wear resistance.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to an artificial quartz slab and a preparation method thereof. Background technique [0002] Artificial quartz stone plate is based on unsaturated polyester resin and thermal polymer, high temperature curing agent, coupling agent, etc. Artificial quartz slabs of a certain size and shape have characteristics incomparable to other decorative materials because of their hard texture (Mohs hardness 7) and compact structure. Generally, artificial quartz stone plates are suitable for places with relatively high requirements for building materials. [0003] Due to the manual or semi-mechanical operation, it is easy to cause uneven product density, inconsistent thickness, powder lumps and pores on the surface, single color and pattern, and deviations in the ratio of various raw materials during the production process. The performance of the plate is not up to standard and other ...
