Abstract

The invention relates to an alumina basalt foamed door core, which is formed by mixing, foaming and solidifying 0.5-0.8 parts of basalt fiber, 160-200 parts of aluminate cement, 16-20 parts of high alumina cement, 2-16 parts of silica micropowder, 1-5 parts of closed cell perlite, 3-11 parts of polyvinyl alcohol, 0.16-0.2 parts of an intensifier, 1-1.5 parts of a foaming agent and 180-220 parts of water. In the invention, aluminate cement and high alumina cement are mixed to prepare a fireproof material through a compound foaming of the foaming agent and the intensifier. And the fireproof material has the advantages of moderate molding and solidification speed, high molding strength, non retrograde strength in use, high fireproof level and long service life, etc.

Description

technical field [0001] The invention relates to a fireproof material, in particular to a fireproof door core plate filling material with high fireproof grade and high strength. Background technique [0002] Metal anti-theft doors produced at home and abroad are generally filled with foaming materials in the door core panel to achieve fire prevention. The existing related technology is: after batching and stirring fireproof materials such as magnesium oxide, magnesium hydroxide, magnesium sulfate, perlite, etc., after foaming with a foaming agent, it is filled and foamed to form, which not only has fireproof, moth-proof, anti-corrosion, high-strength, Lightweight and other advantages, and the production cycle is short, low cost, has been widely used in various fields of fire prevention. [0003] The patent No. 200710070.830.1 discloses a foaming fire-proof filling material. The preparation method of the material is: mix a certain proportion of oxidized metal, high aluminate ...
