| 摘 要： | 研究了以磷酸三甲苯酯(TCP)、水滑石(LDHs)、氢氧化铝(ATH)复配得到的复合阻燃剂对乙烯-醋酸乙烯酯共聚物(EVM:AV含量大于40%)性能的影响。分别通过氧指数、水平燃烧和拉伸性能测试考察了TCP/LDHs/ATH/EVM复合材料的阻燃性能和力学性能。结果表明,当TCP/LDHs/ATH/EVA为20/35/35/100(质量份数)时,复合材料的极限氧指数(LOI)达到35.2,阻燃级别为FH-1;断裂伸长率达到280%,拉伸强度达到11.0MPa。此复合材料可用于制造阻燃电缆。

| Abstract: | The effect of the composite flame retardant synergistic system on the properties of ethylene-vinyl acetate（EVA） was studied. The system was compounded with trimethylphenyl phosphate（TCP） ,layered double hydroxides （LDHs） ,aluminum hydroxide （ATH） . The flame retardancy of phosphor-containing phenolic resins/LDHs/ATH/EVM composites was examined by using limiting oxygen index （LOI） ,horizontal burning （HB） test. The mechanical properties of TCP/ LDHs/ATH/ EVM composites were investigated by the mechanical measurement. The results indicated that when the mass ratio of TCP/LDHs/ATH/EVM is 20/35/35/100,the composite material keeps the FH 1 rating in horizontal burning test and the LOI value is 35. 2. The elongation percentage at break of TCP/LDHs/ATH/EVM composites is 240% ,and the tensile strength is 14. 0 MPa. This composite may be used to prepare the flame retardant cable. |
