The invention discloses a preparation process of a flame-retardant polyurethane building insulation board. The specific preparation process is as follows: adding flame-retardant high-strength TPU, foaming agent AC, dibutyltin dilaurate, dimethicone and 1, 4-butanediol into a high-speed mixer for uniform mixing, then adding a mixed material into an injection molding machine for injection molding and foaming, and then naturally cooling to room temperature to obtain the flame-retardant polyurethane building insulation board. Phosphate-based diisocyanate, polyisocyanate-based glass fibers and a polymeric polyol monomer are polymerized through a crosslinking effect, two isocyanates of the phosphate-based diisocyanate are directly connected to two benzene rings; after crosslinking, the content of benzene rings on a net structure is increased, and meanwhile, since the polyisocyanate-based glass fibers and the polymeric polyol monomer have relatively high strength, polyurethane prepared by alternately crosslinking and polymerizing the polymeric polyol monomer through the phosphate-based diisocyanate and the polyisocyanate-based glass fibers has relatively high strength.
本发明公开了一种阻燃型聚氨酯建筑保温板的制备工艺，具体制备过程如下：将阻燃型高强度TPU、发泡剂AC、二月桂酸二丁基锡、二甲基硅油和1,4丁二醇加入高速混合机中混合均匀，然后将混合物料加入注射成型机中进行注塑发泡，然后自然冷却至室温，得到阻燃型聚氨酯保温板。本发明磷酸酯基二异氰酸酯和多异氰酸酯基玻璃纤维与聚合多元醇单体之间通过交联作用进行聚合，磷酸酯基二异氰酸的两个异氰酸酯直接连接在两个苯环上，交联后提高了网状结构上苯环的含量，同时由于多异氰酸酯基玻璃纤维和聚合多元醇单体本身具有较高的强度，通过磷酸酯基二异氰酸酯和多异氰酸酯基玻璃纤维对聚合多元醇单体进行交替交联聚合后制备的聚氨酯具有较高的强度。
