High-temperature-resistant heat-preservation dry powder functional film

Abstract

The invention provides a high-temperature-resistant heat-preservation dry powder functional film, which comprises the following components in percentage by mass: 10%-15% of aluminum dihydrogen phosphate powder, 15%-20% of soluble sodium silicate, 3%-5% of silicon tripolyphosphate, 5%-10% of zirconium dioxide, 5%-8% of titanium dioxide, 3%-5% of zinc oxide, 15%-20% of expanded vermiculite, 10%-15%of the volcanic ash, 5%-10% of hollow ceramic microbeads, 3%-5% of fumed silica, and 5%-10% of aluminum oxide short fibers. The preparation method comprises the steps of uniformly stirring the materials, adding water, stirring to form a daub mixture, and coating an object with the daub mixture to obtain the functional film. The film has excellent high temperature resistance, heat preservation, waterproofness and corrosion resistance, is not easy to chemically react with external factors, and is harmless to human bodies.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a high-temperature heat-resisting dry powder functional film. Background technique [0002] With the development of modern industry, equipment in chemical industry, metallurgy, electric power and other industries are under the test of high temperature all the time. Under such harsh conditions, the life of the equipment is reduced, the production cost is increased, and it brings great hidden dangers to safe production. Although There are also reports of high-temperature-resistant materials on the market, but generally speaking, the application is still limited by temperature or cost. With the development of the economy, the requirements for high-temperature resistance, especially for the thermal insulation effect, are increasing. There is an increasing focus on high temperature and thermal insulation coatings. High temperature resistant thermal insulation coatings ca...

Problems solved by technology

[0002] With the development of modern industry, equipment in chemical industry, metallurgy, electric power and other industries are under the test of high temperature all the time. Under such harsh conditions, the life of the equipment is reduced, the production cost is increased, and it brings great hidden dangers to safe production. Although There are also reports of high-temperature-resistant materials on the market, but generally speaking, the application is still limited by temperature or cost. With the development of the economy, the requirements for high-temperature resistance, especially for the thermal insulation effect, are increasing. Increasing focus on high temperature and thermal insulation coatings

High temperature resistant thermal insulation coatings can still maintain certain thermal insulation and physical and chemical properties under high temperature conditions, so that the equipment can withstand high temperatures and play the role of heat insulation and decoration. The current silicone series and ethyl silicate series have the highest temperature resistance Only 700°C, and there are environmental issues
