Abstract

The invention relates to a preparation method for an inorganic fire-resistant foam filling material for door core board. The preparation method comprises the following steps: adding water into anhydrous magnesium chloride, magnesium sulfate, carbon fibre and fire-resistant bamboo stick to prepare a frame mixed liquid by mixing the materials; adding kaoline, soot, light magnesium oxide and closed-cell perlite into the frame mixed liquid to prepare slurry; adding the water into animal protein foaming agent and K12 foaming agent to prepare a mixed foaming agent; and injecting the mixed foaming agent into the slurry by using an air foaming machine, stirring the mixture for foaming, and depositing and forming the foamed mixture into the foam filling material. The preparation method has the advantages of simple and convenient processes, uniformly distributed frame material, high foaming effect, 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, safe use, and wide application range.

Description

technical field [0001] The invention relates to a method for preparing a fireproof material, in particular to a method for preparing a filling material for a fireproof door core board by using inorganic foaming. 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 ...
