可膨胀石墨对氯化聚乙烯/乙烯-乙酸乙烯共聚物热塑性硫化胶力学性能及阻燃性能的影响

研究了可膨胀石墨（EG）的粒径及用量、EG/聚磷酸铵（APP）对氯化聚乙烯（CM）/乙烯-乙酸乙烯共聚物（EVA）热塑性硫化胶（TPV）力学性能及阻燃性能的影响。结果表明,随着EG粒径的增加,CM/EVA TPV的拉伸强度及扯断伸长率呈下降趋势,极限氧指数（LOI）增大,垂直燃烧测试均能达到V-0级别,800℃残炭量（CR800）增加;当EG的粒径为48μm时,CM/EVA TPV的综合性能较佳。随着EG用量的增加,CM/EVA TPV的拉伸强度呈下降趋势,而100%定伸应力呈增加趋势,LOI增大,CR800增加。当EG/APP（质量比）为3/1时,CM/EVA TPV的拉伸强度为11.82...

Summary:研究了可膨胀石墨（EG）的粒径及用量、EG/聚磷酸铵（APP）对氯化聚乙烯（CM）/乙烯-乙酸乙烯共聚物（EVA）热塑性硫化胶（TPV）力学性能及阻燃性能的影响。结果表明,随着EG粒径的增加,CM/EVA TPV的拉伸强度及扯断伸长率呈下降趋势,极限氧指数（LOI）增大,垂直燃烧测试均能达到V-0级别,800℃残炭量（CR800）增加;当EG的粒径为48μm时,CM/EVA TPV的综合性能较佳。随着EG用量的增加,CM/EVA TPV的拉伸强度呈下降趋势,而100%定伸应力呈增加趋势,LOI增大,CR800增加。当EG/APP（质量比）为3/1时,CM/EVA TPV的拉伸强度为11.82 MPa,LOI为31.8%,垂直燃烧测试达到V-0级别,综合性能最佳。

Effect of particle size and amount of expandable graphite（EG） and EG/ammonium polyphosphate （APP） on mechanical properties and flame retardance of chlorinated po- lyethylene （ CM ） /ethylene-vinyl acetate copolymer （ EVA ） thermoplastic vnlcanizates （TPV） were stu-died. The results showed that with the increase of EG particle size, tensile strength and elongation at break of CM/EVA TPV decreased, limiting oxygen index （LOI） increased, vertical burning test reached V-O level and carbon residue at 800 ℃ （CR800 ） in- creased. When the particle size of EG was 48 μm, the com- prehensive performance of CM/EVA TPV was the best. Withthe increase of
