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
The present invention relates to refractory materials manufacturing technology field, especially a kind of making method of flame-retardant fibre board.
Background technology
Flame-retardant fibre board has certain intensity and hardness, and Resistance to wind Erosion is strong, and have stable high-temperature performance, under the condition of high temperature, compressive strength is high, is commonly used for the lagging material of high temperature service.The unit weight of the flame-retardant fibre board of the making method production of existing flame-retardant fibre board is large, and surface is inconsistent with inner hardness, is unsuitable for mechanical workout, and the product's dimensional precision that this flame-retardant fibre board is processed is low.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of making method of flame-retardant fibre board, and large with the flame-retardant fibre board unit weight solving the production of existing method, surface is inconsistent with inner hardness, is unsuitable for the problem of mechanical workout.
In order to solve the problem, the technical solution used in the present invention is: the making method of this flame-retardant fibre board, comprises the raw material of following weight part: aluminum silicate fiber 100 parts ~ 120 parts, silicon-aluminum sol 9 parts ~ 12 parts, tetraethoxy 12 parts ~ 15 parts, additive 8 parts ~ 10 parts;
Its operation steps is as follows:
A. aluminum silicate fiber, silicon-aluminum sol, tetraethoxy, additive is taken by above-mentioned each parts by weight of raw materials, for subsequent use;
B. each raw material is put into pulper, add water and carry out stirring and make cotton pulp;
C. adopt vacuum forming machine that step b gained cotton pulp is made slab;
D. kiln put into by slab, is dried to water ratio lower than 8%, obtains this flame-retardant fibre board the temperature of 100 DEG C ~ 140 DEG C.
In the making method technical scheme of above-mentioned flame-retardant fibre board, technical scheme can also be more specifically: described additive is aluminum oxide fine powder.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect:
The present invention adopts aluminum silicate fiber to make main raw material, and silicon-aluminum sol and tetraethoxy make bonding agent, makes flame-retardant fibre board.Aluminum silicate fiber is a kind of lightweight refractory, has low heat conductivity, excellent thermostability and chemical stability, not containing binding agent and corrosive material.Silicon-aluminum sol improves cohesiveness and the high thermal resistance of original silicon sol and Alumina gel, and film forming properties overcomes the defect of the undercapacity of the excessive and Alumina gel of the fragility of silicon sol; Dried space structure, more porous, increase permeability, improves high temperature strength.Tetraethoxy is mainly used as heat-resistant paint, the coating of chemically-resistant effect, organic synthesis intermediate.The unit weight of the flame-retardant fibre board that the present invention makes is little, and surface is consistent with inner hardness, is suitable for being undertaken being processed into various goods by mechanical means, and the product's dimensional precision of this flame-retardant fibre board processing is high.
