Problems solved by technology

[0002] At present, there is a kind of foamed fireproof board, which is mainly used as fireproof door core and fireproof wall. The biggest disadvantage is that this kind of fireproof material is mainly foamed by magnesium oxide, magnesium chloride and hydrogen peroxide, and an unstable negative salt is formed. Chloride ions can Continuous moisture absorption, very corrosive, so that the core of the fire door or the outer color layer or surface coating of the fire wall corrodes and falls off, and the surface anti-corrosion layer is expensive and cannot be durable, and the performance is unstable, which increases the cost and is difficult to be used as a mature product to promote

Abstract

The invention relates to a non-corrosive environment-friendly foaming fireproof plate and a preparation method thereof. The non-corrosive environment-friendly foaming fireproof plate comprises the following materials in parts by weight: 500-1000 parts of magnesium oxide (MgO), 60-120 parts of magnesium sulfate (MgSO4), 200-500 parts of kaolin (Al2O3-2SiO2-2H2O), 20-30 parts of phosphoric acid (H3PO4), 50-200 parts of hydrogen peroxide (H2O2) and 50-200 parts of water (H2O5). The preparation method comprises the following steps: 1) preparing composite synthesis: firstly placing the magnesium sulfate and water into a container for fully stirring, then adding stirred liquid into magnesium oxide for fully stirring, and then adding little amount of magnesium sulfate for stirring; after stirring evenly, adding proper amount as bonding fireproof filler, and finally adding the hydrogen peroxide; 2) step 1) carrying out oxidation and foaming on the prepared composite synthesis; 3) entering a mold upper pressing machine for shaping according to needed specification after foaming, and adding sizing glass fiber cloth and a surface pulp layer with the thickness of 1-2mm are added on the surface; and 4) finally, entering the mold upper pressing machine for shaping again to obtain a finished product. The product of the invention does not contain magnesium chloride, has phenomena of no corrosion, no halogenide return and no moisture absorption, but also greatly reduces the cost, has no toxicity and pollution, is environment-friendly and has no harm to a human body.
