Improved flame retardant coatings are produced from curable chemical mixtures having at least one phosphorus-containing film former which has hydroxyl and/or methylol functionalities, and at least one nucleophilic organo silane. The silane is capable of undergoing nucleophilic reaction with hydroxyl radical displacement and/or capable of Michael's addition type of reaction via a nucleophilic phosphine compound. Additionally, the curable chemical mixture can involve an interaction polymeric product of the phosphorus-containing film former and nucleophilic organo silane. Also solvents such as water, curing agents, fillers and/or extenders may be present in the mixture.
改进型阻燃涂料是由至少一种具有羟基和/或甲醇官能团的含磷成膜物和至少一种亲核有机硅烷的可固化化学混合物制成的。硅烷能够与羟基自由基置换发生亲核反应和/或通过亲核膦化合物发生迈克尔加成反应。此外,可固化的化学混合物还可包括含磷成膜剂和亲核有机硅烷的相互作用聚合产物。混合物中还可能含有溶剂(如水)、固化剂、填料和/或扩展剂。
