Abstract

The invention relates to a preparation method of a high-strength weather-resistant asbestos tile, and belongs to the technical field of building materials. A silane coupling agent is used to organically modify the surface of nanometer titanium dioxide, the nanometer titanium dioxide, antimony tin oxide and an acrylate emulsion are compounded to prepare a heat insulating coating, and the surface ofan asbestos tile is uniformly coated with the prepared coating, so the asbestos tile has a good weather resistance and a good heat insulating property; a ferrosilicon nitride block is used as a refractory aggregate, ferrosilicon nitride is a metal-ceramic composite block material prepared by a flash combustion synthesis technology, contains about 85% (w) of silicon nitride, has similar chemical and hot strength with the silicon nitride, and has better sintering properties and heat conductivity than the silicon nitride, so the fireproof property of the asbestos tile is improved; the addition of asphalt improves the waterproof performance of the asbestos tile; and the silicon carbide has stable chemical properties, a high heat conduction coefficient, a small heat expansion coefficient and good wear resistance, so the addition of the silicon carbide enhances the strength and the fire resistance of the asbestos tile.

Description

technical field [0001] The invention relates to a preparation method of a high-strength weather-resistant asbestos tile, which belongs to the technical field of building materials. Background technique [0002] Asbestos tile is a waterproof material for roofs. It has the advantages of large sheet and effective use area, fire prevention, moisture resistance, corrosion resistance, heat resistance, cold resistance, and light weight. The formula and production method of the traditional asbestos tile is to use asbestos fiber and cement as raw materials and pressurize the board. It is divided into three types in terms of specifications: large wave, medium wave and small wave. In addition, there are matching tiles for these three types of tiles. Herringbone tiles used to cover the roof ridge. [0003] Existing asbestos tiles are formed mechanically by cement, pulp, asbestos, glass fiber, etc., cement and pulp are used as the main components of the tile, and asbestos fibers are use...
