Problems solved by technology

At present, the high-density, high-strength, and heat-resistant boards used in China are mainly produced with asbestos as raw material. Because asbestos will cause great harm to the human body, the use and production of asbestos have been completely banned in Europe, America and developed countries, and other countries have also banned the use in different fields. , although my country has not completely banned it, it will gradually ban it

Abstract

The invention discloses a non-asbestos high-density temperature and wear resisting heat insulation plate. The heat insulation plate is characterized by comprising, by weight, 200-260 parts of kaolin, 15-40 parts of alumina powder, 200-260 parts of aluminum silicate refractory fiber, 10-20 parts of dry paper pulp, 5-15 parts of glass fiber, 10-20 parts of cationic starch, 1-1.5 parts of polyvinyl alcohol and 1-1.5 parts of high-elastic emulsion. The non-asbestos high-density temperature and wear resisting heat insulation plate completely has no asbestos, eliminates environment risks brought by asbestos fiber in the production, maintenance and cleaning processes, is environmentally friendly and has the advantages of resisting high temperature, high pressure, bending and wear, being high in density and good in tenacity and the like. The high temperature lower than or equal to 1200 DEG C can be resisted, and the density reaches up to 900-1100 kg / m<3>. The tenacity is good, and the compression ratio can reach 1:1.4. The shot content in the non-asbestos high-density temperature and wear resisting heat insulation plate is low, and it is ensured that products making contact with the heat insulation plate are not damaged in the using process.

Description

technical field [0001] The invention relates to the field of refractory and heat insulation material processing technology Background technique [0002] High-density, high-strength, temperature-resistant, wear-resistant insulation boards are mainly used for the transmission rollers of the steel belt conveying device of the cold acid treatment annealing furnace of the stainless steel production line, the driving roller of the flat glass conveying device of the float glass production line, and the continuous melting and continuous casting steel plate production line On the transmission roller of the steel belt conveying device and the high temperature resistant sealing gasket and other equipment and components. It has the advantages of high temperature resistance, high density, high pressure resistance, flexural resistance, and good product toughness. At present, the high-density, high-strength, and heat-resistant boards used in China are mainly produced with asbestos as ra...
