摘要
以氢氧化镁(MH)和氢氧化铝(ATH)为无卤基材,结合硼酸锌、红磷和硅酮复配制备无卤阻燃剂。将阻燃剂进行改性后与EVA/LDPE共混制备新型无卤阻燃材料。通过正交试验法,研究不同配方无卤阻燃剂对材料的拉伸性能和阻燃性能的影响,进而获得最佳的复配阻燃剂配方。结果表明,在ATH和MH总量为60份的情况下,当MH∶ATH为5∶1,硼酸锌加入量20份,红磷加入量4份,硅酮用量为3份时,复配后无卤阻燃剂对EVA/LDPE的阻燃性能满足垂直燃烧等级UL-94V-0级,机械性能也较好。
The aluminum magnesium composite halogen-free flame retardant was mixed with Mg(OH)2, Al(OH)3, zinc borate, red phosphorous and silicone. The EVA/LDPE new style halogen-free retardant composites were prepared by direct blending methods after compounding flame retardant modified by coupling agent. Tensile and flame retardant proper-ties of the material were studied using different prescription. When the ratio of MH : ATH was 5 : 1, zinc borate was 20phr, red phosphorous was 4phr,silicone was 3phr, the flame retardant properties of the material met UL94 V-0 requirements, and the mechanical properties were also well.
