Abstract

Considering the poor compatibility and water-resistance of sulfonate flame retardants for polycarbonate (PC), an efficient S/N-based flame retardant named 1,3,5,7-tetrakis(phenyl-4-sulfonyl-melamine)adamantane (ASN) has been developed. Fire properties studies of PC/ASN blends indicate that the addition of 0.10 wt % ASN imparts a V-0 rating and a limited oxygen index (LOI) value of 30.1% to PC specimens, and ASN can suppress the heat and toxic gas release of PC composites. Additionally, PC/ASN blends are believed to be exceptional materials for outdoor PC applications due to their superior water-resistance properties. Moreover, mechanical properties were further systematically investigated, and the correlative results indicate that the tensile strength and rigidity of specimens are improved with the addition of ASN.

摘要

考虑到磺酸盐类阻燃剂与聚碳酸酯（PC）的相容性和耐水性较差，一种名为1,3,5,7-四（苯基-4-磺酰基-三聚氰胺）金刚烷（ASN）的基于S/N的高效阻燃剂被开发出来。PC/ASN共混物的燃烧性能研究表明，添加0.10 wt%的ASN可使PC试样达到V-0等级，极限氧指数（LOI）值为30.1%，并且ASN可以抑制PC复合材料的热量和有毒气体释放。此外，由于其优异的耐水性，PC/ASN共混物被认为是户外PC应用的理想材料。此外，还进一步系统地研究了力学性能，相关结果表明，添加ASN后试样的拉伸强度和刚性得到了提高。
