Abstract

The invention relates to an inorganic fire-resistant foam filling material for a door core board. The filling material is mainly prepared by foaming slurry by a foaming agent, wherein the slurry comprises the following components in part by mass: 15 to 25 parts of anhydrous magnesium chloride, 5 to 15 parts of magnesium sulfate, 0.5 to 0.8 parts of carbon fibre, 0.2 to 0.3 parts of fire-resistant bamboo stick, 5 to 10 parts of kaoline, 3 to 6 parts of soot, 45 to 55 parts of light magnesium oxide, 1.5 to 2.5 parts of closed-cell perlite and 25 to 35 parts of water; and the foaming agent comprises the following raw materials in part by mass: 1.5 to 2.5 parts of animal protein foaming agent, 1 to 2 parts of K12 foaming agent and 25 to 30 parts of water. The frame material in the foam material of the invention has the characteristics of uniform distribution, high foaming efficiency, stable foaming structure, dense holes and good sound insulation effect; and the foamed material has the characteristics of high fire-resistance rating, strong fire resistance without toxicity or side effect, and safe use, and is worthy of popularizing and using.

Description

technical field [0001] The invention relates to a fireproof material, in particular to an inorganic foamed fireproof door core board filling material. Background technique [0002] At present, the metal anti-theft doors produced at home and abroad are generally filled with foaming materials in the door core board to achieve the fire prevention effect. 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 protection. [0003] For example, the patent No. 200710070830.1 discloses the foaming refractory filling material. The preparation method of the material is: mix a certain proportion of Oxymetha, high a...
