Problems solved by technology

[0002] The main raw material of the original thermal insulation tile is aluminum. With the development of science and technology, a new type of magnesia cementitious material thermal insulation tile has begun to attract people's attention. The main raw material of this thermal insulation tile is magnesium oxide, and the outer layer is composited with plastic and aluminum foil. It is commonly known as aluminum-plastic composite insulation tile, but the plastic on the surface of this insulation tile on the market is often easily corroded by acid and alkali, and has poor fire resistance, easy to fall off, and is not weather-resistant.

Abstract

The invention discloses a heat-insulating tile. The heat-insulating tile comprises a surface layer, a middle layer and a bottom layer, which are compounded together by co-extrusion, wherein the surface layer and the bottom layer are aluminum foil layers; the middle layer sequentially consists of a sizing agent, glass fiber, a sizing agent, glass fiber and a sizing agent, wherein the sizing agent is a mixture of magnesium oxide, waste circuit board powder, saw dust, stone powder, a magnesium chloride aqueous solution and a modifying agent. By adopting the waste material, the heat-insulating tile is not only environment-friendly, non-toxic and free of radiation, and strong in heat-insulating and light-reflecting effects, but also corrosion-resistant, unlikely to corrode by acid and alkali, and strong in fireproof performance. The heat-insulating tile is formed by compounding and co-extruding a plurality of layers of materials, so that the heat-insulating effect is achieved more effectively.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to an acid-proof, alkali-proof and corrosion-resistant environmentally friendly heat-insulating tile. Background technique [0002] The main raw material of the original thermal insulation tile is aluminum. With the development of science and technology, a new type of magnesia cementitious material thermal insulation tile has begun to attract people's attention. The main raw material of this thermal insulation tile is magnesium oxide, and the outer layer is composited with plastic and aluminum foil. It is commonly known as aluminum-plastic composite heat insulation tile, but the plastic on the surface of this heat insulation tile on the market is often easily corroded by acid and alkali, and has poor fire resistance, easy to fall off, and is not weather resistant. Contents of the invention [0003] The purpose of the present invention is to provide a heat-insulating til...
