Abstract

The invention relates to a smoke-free and tasteless ceramic fiber board, which belongs to the technical field of ceramic fiber materials. The smoke-free and tasteless ceramic fiber board comprises raw materials and is characterized in that the raw materials do not contain organic bonding agents; and the manufactured ceramic fiber board is smoke-free and tasteless. The smoke-free and tasteless ceramic fiber board does not contain volatile organic compounds in the using process, belongs to green environmental-friendly inorganic materials, has excellent performances of heat resistance, fire resistance and heat insulation and excellent strength, greatly reduces the volume density and the production cost, and can be used for the fireproofing and heat preservation of household appliances and ceramic kiln industries. Compared with the conventional smoke-free and tasteless board, the smoke-free and tasteless ceramic fiber board expands the application field of ceramic fibers.

Description

technical field [0001] The invention belongs to the technical field of ceramic fiber materials, and in particular relates to a smokeless and odorless ceramic fiber board. Background technique [0002] Traditional ceramic fiber boards, such as 1050 fiber boards, building fireproof boards, slag wool insulation boards, mineral wool insulation decorative sound-absorbing ceilings, asbestos boards, high-temperature boards, etc., all have a certain strength by introducing binders. A large part of the agent is an organic binder. The advantages of the organic binder are strong adhesion and good bond strength. However, the organic binder will be carbonized at 300-800 ° C, producing a lot of smoke and pungent odor. Although this process will be completed quickly as the temperature rises, it generally does not affect the use. However, some special application fields such as the ceramic kiln, the home appliance industry, and the backing insulation layer and hot surface refractory layer ...
