摘　　要：对无机阻燃剂进行表面改性,从而提高其与高分子聚合物的相容性和分散性。将改性后的阻燃剂填充到EVA体系中,通过对阻燃性能和机械性能的测定,进而得到了最适宜阻燃剂和填充量。通过对EVA热熔胶中其它组分的考察,得到了环保型阻燃EVA热熔胶的最适宜配比。结果表明:复配型阻燃剂为最适宜阻燃剂,加入量为5%(质量分数,下同);当EVA加入量为45%,氢化C5石油树脂为35%,石蜡为7.5%,SBS为1%,CaCO3为5%,增塑剂为1%,抗氧剂为0.5%时,制备的热熔胶产品性能达到了国内热熔胶的行业标准,同时又拥有了阻燃和环保两大优势,能很好的应用于木质地板、地毯和对防火性能要求较高的材料的黏结。The inorganic flame retardant was surface modified to enhance compatibility and dispersion within the polymer.The modified flame retardant was filled to the EVA systems and the flame-retardant and mechanical properties were determined to optimize flame retardants and the addition amount.The other composition filled in the EVA hot melt was also analyzed and eventually optimal addition ratio was obtained for a green flame retardant EVA hot melt adhesive.Experimental results show that the optimum composition in flame retardant is as follows： EVA 45%（mass percentage,the same below）,hydrogenated C5 petroleum resin 35%,paraffin 7.5%,SBS 1%,CaCO3 5%,flame retardants 5%,plasticizers 1%,antioxidant 0.5%.The prepared hot melt adhesive product can meet the domestical industrial standard,and have two major advantages of environmental protection and inflaming retarding.Therefore it will be well applicated in the fields of wood flooring,carpet and the bonding of materials with upper fire performance demanding.
