Problems solved by technology

Nevertheless, artificial quartz stone plates also have certain disadvantages, such as poor fire resistance
In the production process of artificial quartz stone, the general resin content is more than 6%. Since the resin is combustible, when the resin content of artificial quartz stone reaches more than 3%, the fire resistance of the product is extremely low, which greatly limits the artificial quartz stone. The application of stone in various complex conditions, especially in large public facilities and places with high fire protection requirements

Abstract

The invention discloses a fireproof artificial quartz stone sheet and a manufacturing method thereof. The artificial quartz stone sheet comprises the following components in parts by weight: 30-80 parts of 6-100mesh quartz stone, 30-60 parts of 325mesh quartz powder, 5-10 parts of broken glass, 10-20 parts of 50-100mesh red-silica powder or white afrodite powder, 5-15 parts of 100-150mesh kyanite powder or andalusite powder or sillimanite powder, 1-10 parts of 100-200mesh zirconium silicate powder or yttrium-stabilized zirconium oxide powder, 5-10 parts of unsaturated resin, 0.3-0.5 part of an additive and 0.3-0.8 part of a pigment. During the preparation, by adding red-silica powder or white afrodite powder, kyanite powder or andalusite powder or sillimanite powder and zirconium silicate powder or yttrium-stabilized zirconium oxide powder, the compressive strength and fireproof and fire-retardant properties of the artificial quartz stone sheet disclosed by the invention are increased and meanwhile, the manufacturing method is simple and is suitable for industrial production and has broad market prospects.

Description

technical field [0001] The invention belongs to the technical field of building material manufacturing, in particular to a fireproof artificial quartz stone plate and a manufacturing method thereof. Background technique [0002] Compared with artificial marble slabs, artificial quartz stone slabs have the characteristics of high curvature, high compressive strength, high Mohs hardness, and low water absorption. They are gradually favored by users at home and abroad, and are widely used in cabinets, bathrooms, offices and The floor, wall decoration and home furnishing industry of large shopping malls. Nevertheless, artificial quartz stone plates also have certain disadvantages, such as poor fire resistance. In the production process of artificial quartz stone, the general resin content is more than 6%. Since the resin is combustible, when the resin content of artificial quartz stone reaches more than 3%, the fire resistance of the product is extremely low, which greatly limi...
