Soluble ceramic fiber plate and preparing method thereof

Abstract

The invention discloses a soluble ceramic fiber plate and a preparing method thereof. The plate is formed by pressing a fiber blanket, and the fiber blanket is prepared from, by weight, 85-90 % of soluble fiber, 2-4 % of thermal insulation filler, 3-5 % of fireproof filler, 3-5 % of inorganic adhesive and 0.5-1.5 % of organic binding agent. The soluble ceramic fiber plate is harmless to the humanbody, small in volume weight, low in thermal conductivity and high in fireproof level, can achieve pattern pressing and is simple in production technology.

Description

technical field [0001] The invention relates to a fireproof board, in particular to an environmentally friendly soluble ceramic fiber board and a preparation method thereof. Background technique [0002] Traditional thermal insulation materials such as glass wool, mineral wool, and aluminum silicate ceramic fiber are not only chemically inert but also carcinogenic fiber materials. With the development of my country's industry, the amount of thermal insulation materials is increasing, and its impact on the environment must be considered. The new version of the national standard for fire doors GB12955-2008 puts forward stricter requirements on the core board of fire doors: first, the material of the core board must reach the A1 level of combustion performance of GB 8624. Up to 3 hours; the use of environmentally friendly materials is required to reach the ZA2 level of smoke toxicity hazard classification stipulated in GB / T20285. If the filling material in the door leaf shoul...

Problems solved by technology

At present, most domestic enterprises choose non-fiber heavy boards, such as expanded perlite boards, magnesium oxide perlite boards, etc. Embossing can only be engraved, the processing technology is complicated, and the dust pollution on the production site is serious, and the environmental protection is poor
