Embodiment 1

[0020] A soluble ceramic fiber board according to the invention is formed by pressing a fiber blanket, and the fiber blanket includes 88wt% of calcium magnesium silicate ceramic fiber, 4wt% of expanded perlite as a lightweight heat-insulating filler, 4wt% of refractory filler basalt, and inorganic binder silicon Sol 3wt%, organic binder silicone modified resin 1wt%, wherein basalt is a natural inorganic mineral, plays the role of vitrified agent, increases the refractory temperature and enhances the mechanical properties of the fiber blanket.

Embodiment 2

[0022] A soluble ceramic fiber board according to the invention is formed by pressing a fiber blanket, the fiber blanket includes 85.5wt% of magnesium silicate ceramic fiber, 3wt% of expanded vermiculite as a lightweight heat-insulating filler, 5wt% of refractory filler basalt fiber, and an inorganic binder Silica sol 5wt%, organic binder organosilicon modified resin 1.5wt%, wherein basalt fibers are artificially processed inorganic minerals, play the role of vitrified agent, increase the refractory temperature and enhance the mechanical properties of the fiber blanket.

Embodiment 3

[0024] A soluble ceramic fiber plate of the present invention is formed by pressing a fiber blanket, and the fiber blanket includes 90wt% of magnesium silicate ceramic fiber, 2wt% of expanded vermiculite for lightweight heat-insulating filler, 3wt% of refractory filler basalt fiber, inorganic binder silicon Sol 4.5wt%, organic binder silicone modified resin 0.5wt%.

[0025] Soluble fiber is based on SiO 2 , CaO, and MgO are refractory fibers with a short half-disappearance period (12 days) in the human body and good biosolubility. The soluble fiber in the soluble ceramic fiber sheet of the present invention can also be calcium magnesium silicate ceramic fiber, Calcium silicate fibers other than magnesium silicate ceramic fibers, expanded graphite can also be used as light heat insulating fillers in addition to expanded vermiculite and expanded perlite, and zirconia can also be used as refractory fillers in addition to basalt and basalt fibers. The prepared soluble ceramic fib...

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...
