The invention discloses an anti-burst fireproof coating. The anti-burst fireproof coating comprises, by weight, 40-60 parts of reinforced glue, 100-120 parts of high-alumina cement, 10-20 parts of a pressure relief expanding agent, 5-10 parts of reinforced fibers, 3-5 parts of a rheological agent and 200-300 parts of a water solvent; the rheological agent is a mixture of hydrogenated castor oil and polyvinyl alcohol fibers; the reinforced glue comprises, by weight, 5-10 parts of polyvinyl alcohol, 50-100 parts of ammonia water and 5-20 parts of a modifier; and the modifier is a mixture of ammonium sulfate, sodium hydrogen sulfite and sodium borate. Polyvinyl alcohol is used as a main film-forming material, the added ammonium sulfate, sodium hydrogen sulfite, sodium borate, wollastonite, expanded vermiculite, amorphous silica and sepiolite are matched for use, so the fireproof coating is endowed with relative flexibility and adhesive force, the tight combination degree between the fireproof coating and a base material is improved, high adhesive force and ductility are formed, and the probability that the fireproof coating bursts under the action of high temperature and open fire isreduced, thereby the fireproof performance of the base material is improved.
本发明公开了一种抗爆裂防火涂料，包括以下重量组分：40～60份的增强胶水，100～120份的高铝水泥，10～20份的泄压膨胀剂，5～10份的增强纤维，3～5份的流变剂，以及200～300份的水溶剂；所述流变剂为氢化蓖麻油和聚乙烯醇纤维的混合物；其中，所述增强胶水包括5～10份的聚乙烯醇，50～100份的氨水，5～20份的改性剂；所述改性剂为硫酸铵、亚硫酸氢钠和硼酸钠的混合物。本发明通过聚乙烯醇为主要成模材料，加入的硫酸铵、亚硫酸氢钠、硼酸钠、钙硅石、膨胀蛭石、无定型硅石与海泡石配合使用，赋予防火涂料相对的柔韧性和附着力，提升了防火涂料与基材之间的紧密结合度，形成较强的附着力和延展性，减少了防火涂料在高温和明火的作用下发生爆裂的几率，从而提升基材的防火性能。
