Abstract

The invention discloses a quartz stone slab. The quartz stone slab is prepared from, by mass, 20-30% of quartz powder, 40-45% of quartz sand, 1-3% of silane coupling agent, 0.5-3% of curing agent, 1-3% of ferric chloride, 3-6% of sodium polyacrylate, 10-13% of heavy calcium carbonate, 1-2% of accelerant and 5-15% of unsaturated polyester resin. According to the quartz stone slab, ferric chloride,sodium polyacrylate and other raw materials are mixed, the obtained quartz stone slab is high in strength and rigidity and low in water absorption rate, and cannot be shrunk or cracked; the decorativeperformance of the quartz stone slab is satisfied, the quartz stone slab also has excellent waterproof performance and mechanical performance, the comprehensive performance index of the slab is increased, the service life of the slab is prolonged, and the application field of finished products of synthetic quartz stone slabs is greatly expanded.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a quartz stone plate and a preparation method thereof. Background technique [0002] Artificial quartz stone is a new type of polymer material which is mixed with natural quartz sand, quartz powder, resin and pigment and processed by special equipment. Quartz stone has many varieties, good decorative effect, high hardness, good wear resistance, strong stain resistance, corrosion resistance, environmental protection, no radiation, high temperature resistance without deformation, high strength, good toughness, and easy connection. Artificial quartz stone plate has no radiation and has good antifouling effect. It is the first choice of green and environmental protection home decoration material to replace natural marble. Compared with natural stone, quartz stone has unique advantages such as non-toxic, pollution-free, and rich colors; compared with artificial...
