Abstract

The invention belongs to the field of materials and relates to modified inorganic fireproof rubber comprising the following raw materials in percentage by weight: 50-65% of silicate, 30-45% of silicon dioxide and 5-15% of aluminum phosphate, wherein the silicate is one or a mixture of sodium silicate, magnesium silicate and potassium silicate. The modified inorganic fireproof rubber is prepared from a high-temperature-resistant, nontoxic and harmless inorganic material so as to be stable in chemical property, high in thermal stability and incapable of combusting at high temperature or generating toxic gases harmful to human bodies; and the modified inorganic fireproof rubber is excellent in waterproofness, resistant to water and humid environments and incapable of generating a rubber removal phenomenon.

Description

technical field [0001] The invention belongs to the field of materials, and relates to a fireproof glue, in particular to a modified inorganic fireproof glue. Background technique [0002] At present, the glue mainly used in the fire door industry is polyurethane foam glue added with certain flame retardant materials for bonding or general inorganic fireproof glue. The disadvantage of these two methods is that although the styrofoam can achieve a certain fire resistance by adding a certain flame retardant material, its fire resistance limit is far from meeting the standards required by fire doors, and it will still burn at higher temperatures and generate harmful gases. Threatening to life, it is not conducive to the escape of personnel at the fire scene and even has the opposite effect. Its flammable characteristics at high temperatures will greatly reduce the fire resistance time of fire doors; A modified fireproof adhesive and its preparation method disclosed on June 18,...
