Abstract

The invention relates to the technical field of building materials, and specifically discloses a high-strength insulation stone plate and a preparation method thereof. The density of the high-strength insulation stone plate is below 1.2 g / cm<3>, and an insulation plate is combined with the back surface of the high-strength insulation stone plate; the high-strength insulation stone plate per cubic centimeter contains 2000 or more holes, and the holes are independent holes. The high-strength insulation stone plate is prepared from the following raw materials by weight percent: 40% to 60% of waste ceramic tiles, 35% to 45% of kaolin, 0.5 to 2.0% of foaming agents, 3% to 8% of ore sand and 5% to 10% of glaze. The high-strength insulation stone plate contains the independent holes, and therefore, the high-strength insulation stone plate has good insulation performance; in addition, the high-strength insulation stone plate has the advantages of light weight, small density and high strength, has a good insulation function and belongs to a green environment-friendly product because the waste recycling proportion exceeds 40%; the surface texture of the stone plate is close to natural stones, physical and chemical properties are stable, weathering is difficult, and the high-strength insulation stone plate can be firmly pasted on an outer wall.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a high-strength thermal insulation stone board and a preparation method thereof. Background technique [0002] As a high-grade building decoration material, stone panels are widely used in indoor and outdoor decoration design, curtain wall decoration and public facilities construction. At present, the common stone panels on the market are mainly divided into natural stone panels and artificial stone panels. Natural stone slabs are mainly divided into three categories according to their physical and chemical properties: marble, granite, and sandstone. Artificial stone panels can be divided into cement type artificial stone, polyester type artificial stone, composite type artificial stone and sintered type artificial stone according to the material. [0003] However, at present, artificial stone panels generally have defects such as low product strength, poor chemical ...
