Problems solved by technology

[0003] In the prior art, the aluminum silicate fiber is often formed by adding a binder and adopting a wet vacuum forming process to form it and have a certain plate strength to expand its application field. Although it still has good thermal insulation performance and fire resistance, its The strength of the board is far from enough, which limits its further development as a fireproof insulation board

Abstract

The invention provides an inorganic silicon crystal plate and a manufacturing method thereof. The inorganic silicon crystal plate comprises the following raw materials in parts by weight: 7-12 parts of flint clay, 16-22 parts of high-purity alumina powder, 32-37 parts of quartz sand, 18-22 parts of high-purity silicon oxide powder, 11-16 parts of zircon sand, 28-34 parts of silica sol and 1-3 parts of boric acid. The inorganic silicon crystal plate is prepared by heating, melting and blowing raw materials including flint clay, high-purity aluminum oxide powder, quartz sand and zircon sand into fibers, spraying and attaching a silica sol composite solution dispersed with the high-purity silicon oxide powder to the surfaces of the fibers, performing mold pressing to form a base plate, and finally performing high-temperature sintering. The obtained inorganic silicon crystal plate is resistant to corrosion, low in deformation, light in weight, high in strength and capable of insulating heat and preserving heat, is an excellent substitute of an existing fireproof heat preservation plate, can be used at the highest temperature of 1500 DEG C, and can meet the application requirements of smoke prevention and exhaust air pipes, building fireproof plates, fireproof door inner materials and the like as a light, high-strength, high-temperature-resistant and fireproof plate.

Description

technical field [0001] The invention relates to the field of thermal insulation and fireproof materials, in particular to an inorganic silicon crystal plate and a manufacturing method thereof. Background technique [0002] The aluminum silicate fiber made of coke gemstones as the main raw material and sprayed after high-temperature melting is an excellent fireproof and thermal insulation material. Insulation lining or lining material for industrial furnaces. [0003] In the prior art, the aluminum silicate fiber is often formed by adding a binder and adopting a wet vacuum forming process to form it and have a certain plate strength to expand its application field. Although it still has good thermal insulation performance and fire resistance, its The strength as a board is far from enough, which limits its further development as a fireproof insulation board. Contents of the invention [0004] Based on the above, the present invention provides an inorganic silicon crystal ...
