摘要
利用正交设计法研究由Al(OH)3和Mg(OH)2为主阻燃剂,红磷等为增效剂,采用原位反应增容技术制备的阻燃ABS材料。通过方差分析,探讨了含极性基团的乙烯基单体A、B和引发剂DCP的用量以及它们之间的相互作用对阻燃ABS力学性能、阻燃性能的影响。实验结果表明,引发剂DCP和含极性基团的乙烯基单体A用量的变化对阻燃ABS各指标的影响显著,含极性基团的乙烯基单体B的用量改变对阻燃ABS的性能无明显影响,但是这3个因素之间存在相互作用,而且这些交互作用对阻燃ABS的综合性能有一定的影响,当引发剂DCP、含极性基团的乙烯基单体A和B的用量分别为1 5份、10份和30份时,制备的阻燃母粒可使阻燃ABS获得最好的综合性能。
The orthogonal design was utilized to study the materials of halogen-free flame retardant acrylonitrile-butadiene-styrene(ABS) prepared by in-situ reactive compatibility using Al(OH)3 and Mg(OH)2 as primary flame retardant and red phosphorus as synergistic agent.The effects of contents and their interaction of initiator DCP and vinyl monomers containing polar groups on the mechanical properties and flame-retardant property of flame retardant ABS were investigated by variance analysis.The experimental results showed that the varied contents of initiator DCP and vinyl monomer A containing polar groups had obvious influences on the mechanical properties and flame-retardant property of flame retardant ABS,and contents of vinyl monomer B containing polar groups had no great influences on their mechanical properties and flame-retardant property.But there were interactions in these three factors and their interactions had some influences on the property of flame retardant ABS.When content of initiator DCP,vinyl monomer containing polar groups A and B was 1.5phr, 10phr and 30phr respectively,the flame retardant ABS prepared by flame-retardant masterbatch had the best properties.
