用于阻燃聚氨酯的有机硅主链预聚物
摘要：
本发明的实施方式提供涂料，其包括以下物质的反应产物：至少一种硅酸钠溶液，具有约2至约4的羟基和胺基官能度中至少之一的至少一种异氰酸酯反应性组分，至少一种膨胀填料，至少一种填料，任选的悬浮剂，和至少一种具有异氰酸酯官能团的预聚物。所述预聚物包括预聚物反应混合物的反应产物。所述预聚物反应混合物包括：至少一种异氰酸酯，羟基官能度为约2至约6的至少一种多元醇，和具有至少一个异氰酸酯反应性部分的至少一种有机硅表面活性剂。
摘要（英）：

Embodiments of the invention provide for coatings that include the reaction product of at least a sodium silicate solution, at least one isocyanate reactive component having at least one of a hydroxyl and an amine functionality of between about 2 and about 4, at least one intumescent filler, at least one filler, optionally a suspension agent and at least one prepolymer having isocyanate functional groups. The prepolymer includes the reaction product of a prepolymer reaction mixture. The prepolymer reaction mixture includes at least one isocyanate, at least one polyol having an hydroxyl functionality of between about 2 and about 6, and at least one silicone surfactant having at least one isocyanate reactive moiety.
