摘要
低毒的天然纤维阻燃剂是用双氰胺、甲醛为原料在70～75℃的条件下合成的,通过在棉布上测试,氧指数可达31,结果表明双氰胺甲醛树脂是一种阻燃性能良好的低毒聚合物。
The low poisonous flame retarder for natural fibre was synthesized in 70～75 ℃ using dicyandiamide and formaldehyde. Through the tests with cotton cloths, limiting oxygen index was 31.The results showed that dicyandiamide formaldehyde resin is a kind of better flame retardance polymer with low poison.
