Abstract
The invention discloses a production method of a flame-retardant fiber board and relates to the technical field of preparation of refractory materials. The flame-retardant fiber board is prepared from the following raw materials in parts by weight: 100-120 parts of aluminium silicate fiber, 9-12 parts of silicon-aluminium sol, 12-15 parts of ethyl orthosilicate and 8-10 parts of additive. The production method of the flame-retardant fiber board comprises the following operation steps: weighing the raw materials according to the parts by weight, putting the raw materials into a thick liquid making machine, adding water and stirring for obtaining cotton pulp, preparing the cotton pulp into a board blank by adopting a vacuum moulding machine, putting the board blank into a drying chamber, and drying at the temperature of 100-140 DEG C until moisture content is lower than 8%, so that the flame-retardant fiber board is obtained. Compared with the prior art, the flame-retardant fiber board obtained by adopting the production method disclosed by the invention has low volume-weight, the hardness of the surface is consistent with that of the interior, the flame-retardant fiber board is applicable to processing of various finished products by virtue of mechanical equipment, and the finished products processed by adopting the flame-retardant fiber board is high in dimension accuracy.
Description
technical field [0001] The invention relates to the technical field of refractory material manufacturing, in particular to a method for manufacturing 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 refractory fiberboard produced by the existing refractory fiberboard manufacturing method has a large volume, and the hardness of the surface and the inside is not consistent, so it is not suitable for machining, 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 method for making refractory fiberboard, so as to solve the problem that the refractory fiberboard produced by th...
