摘要
以正硅酸乙酯(TEOS)、甲基三甲氧基硅烷(MS)为包覆前驱体,高聚合度聚磷酸铵(APPⅡ)为载体,采用溶胶-凝胶工艺,制备硅氧烷包覆聚磷酸铵协同阻燃剂.通过电镜表征(SEM、TEM)证实阻燃剂的包覆结构,并详细讨论了溶胶及协同阻燃剂制备工艺的影响因素.在此基础上,将该阻燃剂与水性聚氨酯复合制成环保阻燃涂层剂并用于织物的阻燃涂层整理,结果表明:能赋予织物优异的阻燃、高强力及防"霜化"等效果.
Siloxane-enwrapped ammonium polyphosphate, a synergic fire retardant, was prepared by the sol-gel technology with ethyl orthosilicate （TEOS） and methyltrimethoxysilane （MS） as the enwrapping precursors and highly polymerized ammonium polyphosphate （APP II） as the carrier. The enwrapping structure of the fire retardant was characterized by SEM and TEM. The factors affecting the sol and synergetic fire retardant preparation were discussed in details. An environment-friend fire retardant coating agent was made by compounding this fire retardant and waterborne polyurethanes, and the product was used for coating finishing of fabrics. The results showed that the finished fabrics had excellent fire retardancy, strength and ＂frost-off＂ effect.
