Abstract

The invention discloses a fireproof fiber board and relates to the technical field of fireproof material manufacture. The fireproof fiber board is prepared from the following raw materials in parts by weight: 100-120 parts of aluminum silicate fibers, 9-12 parts of silicon-aluminum sol, 12-15 parts of tetraethyl orthosilicate and 8-10 parts of additives. Compared with the prior art, the fireproof board is small in volume weight and consistent in surface and interior hardness, and can be processed into various products by use of mechanical equipment; the products processed from the fireproof fiber boards are high in dimensional accuracy.

Description

technical field [0001] The invention relates to the technical field of refractory material manufacture, in particular to a refractory fiberboard. Background technique [0002] Refractory fiberboard has certain strength and hardness, strong wind erosion resistance, stable performance at high temperature, high compressive strength at high temperature, and is often used as heat insulation material for high temperature equipment. The existing refractory fiberboard has a large volume, and the hardness of the surface and the inside is not consistent, so it is not suitable for processing with mechanical equipment, and the products processed by the refractory fiberboard have low dimensional accuracy. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a refractory fiberboard to solve the problem that the existing refractory fiberboard has a large volume, the hardness of the surface and the inside are consistent, and it is no...
