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 [0001] The invention belongs to the technical field of ceramic fiber materials, and in particular relates to an inorganic bonded ceramic fiber board. Background technique [0002] Traditional ceramic fiberboards need to add a small amount of organic binders such as starch in the production process to make the ceramic fiberboards have a certain strength. The advantages of organic binders are strong adhesion and high bond strength, but organic binders will be carbonized at 300-800°C, resulting in thick smoke and pungent odor. With the further development of ceramic kilns and household appliances, these fields prefer to use ceramic fiberboards that do not contain any organic binders to meet the special requirements of non-combustible, smokeless and odorless during use. This kind of ceramic fiber board does not contain organic matter due to the use of inorganic binders, and uses non-polluting gas to volatilize under high-temperature conditions, which improves th...
