Abstract
The invention relates to an inorganic combined ceramic fiberboard, which is characterized by being made of following materials in parts by weight: 30-40 parts of aluminum silicate fiber, 5-20 parts of expanded perlite, 0.4-0.8 parts of coagulant, 0.4-0.8 parts of flocculant, 30-46 parts of light burned magnesia powder, 20-30 parts of superfine silicon dioside powder, and 2000-4000 parts of water. According to the inorganic combined ceramic fiberboard, the aluminum silicate fiber is adopted as a base material, and the expanded perlite and other light fillers in certain proportion are added, and the inorganic combined ceramic fiberboard is produced by adopting a method for simultaneously hydrothermal-synthesizing an inorganic binder in a drying process. Since the inorganic binder ceramic fiberboard does not containing organic matters, no polluted gas volatilizes when the inorganic binder ceramic fiberboard is used at high temperature, and the quality of living environment is improved.
Description
Technical field
The invention belongs to the ceramic fiber material technical field, be specifically related to a kind of inorganic in conjunction with ceramic beaverboard.
Background technology
Traditional ceramic beaverboard all needs to add organic bonds such as a spot of starch in process of production, makes ceramic beaverboard have certain intensity.The advantage of organic bond is strong adhesion and cohesive strength height, but organic bond at 300-800 ℃ carbonization can take place, thereby produces thick smoke, and has irritating smell.Along with further exploitation such as ceramic kiln, household electric appliances, the ceramic beaverboard that does not contain any organic bond is more wished to use in these fields, does not fire to satisfy in its use, the particular requirement of smoke-free and tasteless.So this ceramic beaverboard does not contain organism because using inorganic bonding agent, uses pollution-free gaseous volatilization under worst hot case, has improved the quality of living environment.For this reason, proposed to develop the ceramic beaverboard of inorganic combination.
Summary of the invention
The objective of the invention is: provide a kind of inorganic in conjunction with ceramic beaverboard, do not contain organism in the wedding agent, satisfy in use do not fire, the particular requirement of smoke-free and tasteless.
The technical solution adopted for the present invention to solve the technical problems is: provide a kind of inorganic in conjunction with ceramic beaverboard, it is characterized in that being made by the raw material of following parts by weight:
30～40 parts of aluminum silicate fibers
5～20 parts of pearlstones
0.4～0.8 part of condensing agent
0.4～0.8 part of flocculation agent
30～46 parts of light-magnesite powder
20～30 parts of silicon-dioxide ultrafine powders
2000～4000 parts in water.
Described inorganic in conjunction with ceramic beaverboard, it is characterized in that being made by the raw material of following parts by weight:
