| 摘 要： | 将硅烷偶联剂KH-550锚固在氢氧化镁表面,通过聚合反应制备了聚酰亚胺插层接枝的氢氧化镁阻燃剂,将其添加到乙烯-醋酸乙烯酯共聚物(EVA)中并考察了接枝对复合材料阻燃性能、力学性能、热力学性能的影响。结果表明:添加了接枝阻燃剂的EVA与添加未接枝阻燃剂的EVA相比,阻燃性能和力学性能都较高;在阻燃剂添加量为60%时,垂直燃烧性能由V_1提升为V_0,拉伸强度也由10.70 MPa提高为11.29 MPa。 |

| Abstract: | The silane couple KH-550 was anchored on the magnesium hydroxide(MH) surface,polyimide(PI) inserted and grafted MH flame retardant was prepared by polymerization.The modification effect of ethylene vinyl acetate copolymer(EVA) material on flame retardant properties and mechanical properties was studied.The results show that PI grafted MH clearly increases flame retardant properties.In the flame retardant addition level of 60%,the UL-94 vertical burning test enhances from V-1 to V-0,tensile strength enhances... |
