反应注射成型聚氨酯复合材料阻燃性研究

A Study on Flame Retardant Performance of Reaction Injection Molding Polyurethane Composite Materials

通过加入阻燃剂、阻燃聚醚以及提高异氰酸酯指数等方法,确定了高效的复合阻燃剂配方,开发出氧指数为30%～32%的反应注射成型阻燃聚氨酯复合材料。

The formulations of high efficiency composite flame retardant were defined by using the methods such as adding flame retardant, flame retarding polyether, increasing the isocyanate index, and so on. The flame retarding polyurethane composite materials for reaction injection molding （RIM） with oxygen index of 30%-32% were developed.
