Organosilicon-based polycarbonate flame retardant and application thereof

The invention provides an organic silicon-based polycarbonate flame retardant and application thereof, the organic silicon-based polycarbonate flame retardant is prepared by addition reaction of raw material components, the raw material components comprise: an organic compound having a molecular structure simultaneously containing an aromatic group and an unsaturated group, the unsaturated group being a carbon-carbon double bond; and polysiloxane containing a silicon-hydrogen bond. Residue of substances limited by laws and regulations such as polychlorinated biphenyl and organic tin and intervention of toxic and flammable solvents are avoided, the cost is low, and the flame retardant effect is good. 本发明提供一种有机硅基聚碳酸酯阻燃剂及其用途，经原料组分进行加成反应制得，所述原料组分包括：分子结构上同时含有芳香基团和不饱和基团的有机化合物，所述不饱和基团为碳碳双键；含有硅氢键的聚硅氧烷。其避免了多氯联苯、有机锡等法规限制物质的残留以及有毒、易燃溶剂的介入，并且成本低、阻燃效果好。
