摘　　要：研究了以体积质量浓度为60%的高浓度水相Sb2O5胶体为原料制备阻燃剂环己酮/Sb2O5胶体的方法。直接向该水相Sb2O5胶体中加入数种表面活性剂和环己酮,经过胶团在水中聚沉、胶团表面改性、胶团重新分散于环己酮等几个步骤生成环己酮Sb2O5胶体,原水相Sb2O5胶体中的水随之一起成胶。试验表明,该胶体可以与聚氨酯以任意比例互相融合。Using 60% high concentrated Sb2O5/H2O colloid as a raw material, a method for preparation of flame retardant Sb2O5 hexamethylene ketone colloid was studied. Adding several kinds of surfactants step by step into 60% Sb2O5/H2O colloid and then adding hexamethylene ketone as organic solvent,through several processes of coagulation of colloidal particles in water,colloidal particles＂ surface modification and colloidal particles redispersed in cyclohexanone, the Sb2O5/cyclohexanone colloid can be formed. The water in water/ Sb2O5 colloid is formed steadily in Sb2O5/hexamethylene ketone colloid.the experiment result showed that Sb2O5 hexamethylene ketone colloid and polyurethane can be fused fully under any proportions.
