摘要
为了有效改善聚丙烯基体表面的阻燃性能,在不破坏材料基体的前提下,利用高能电子束高效的辐射诱导方法在材料基体表面通过激活自由基引入硼酸锌(4ZnO·B_(2)O_(3)·H2O)单体,通过在聚丙烯聚合物基体表面夺取氢离子产生自由基,成功将阻燃性单体硼酸锌引入聚丙烯聚合物基体。对改性处理过程中的各影响因素逐一进行分析,并应用红外光谱分析(FT-IR)及扫描电子显微镜(SEM)对制备而成的新型阻燃高聚物表面的化学形态及结构变化进行了表征。实验结果证明,在聚丙烯聚合物表面通过诱导接枝方法引入阻燃基团,能够有效提高材料基体表面的阻燃隔热效果,从而有效减少引起火灾的危险性。
In order to effectively improve the flame-retardant properties of the polypropylene matrix surface,without damaging the material matrix,a high-energy electron beam efficient radiation induction method was used to introduce zinc borate(4ZnO·B_(2)O_(3)·H2O)monomer on the surface of the material matrix by activating free radicals.By capturing hydrogen ions on the surface of the polypropylene polymer matrix to generate free radicals,the flame retardant monomer zinc borate was successfully introduced into the polypropylene polymer matrix.The influence factors in the modification process were analyzed one by one,and the chemical morphology and structural changes of the new flame retardant polymer surface were characterized by FT-IR and SEM.The experimental results show that the introduction of flame retardant groups on the surface of polypropylene polymer by induced grafting can effectively improve the flame retardant and heat insulation effect on the surface of the material matrix,thus effectively reducing the risk of fire.
