Synthesis of a novel polyphosphate and its synergism with APP in flame retardant EVA(聚双酚酸苯基磷酸酯的合成及其与APP协同阻燃EVA的研究)
采用来源于生物质资源的双酚酸为原料,利用界面聚合法合成新型阻燃剂聚双酚酸苯基磷酸酯(poly (DPA-PDCP)).探索了时间、催化剂用量、氢氧化钠用量等因素对其产率的影响,在优化的工艺条件下(室温、催化剂摩尔分数为0.04,nNaOH:nDPA = 3,反应时间为0.5 h),poly(DPA-PDCP)产率可达75%.当poly(DPA-PDCP)与APP以1: 4比例复配阻燃EVA,总添加量质量分数为30%时,EVA的氧指数达到25.7%;锥形量热测试表明最大热释放速率降低61%;TGA测试显示起始分解温度较纯EVA提高32 ℃,最大分解温度提高20 ℃,同时在600 ℃的残炭量质量分...
