低烟无卤无磷阻燃热收缩材料的研制

Preparation of heat-shrinkable materal with low-smoke,halogen-free, phosphor-free and flame-retardant by irradiation crosslinking

通过对乙烯-乙酸乙烯酯共聚物(EVA)基材树脂、聚合物相容剂、无卤无磷阻燃体系及辐照加工工艺的研究,获得了一种辐照交联低烟无卤无磷纳米阻燃热收缩材料,此热收缩材料具有优良的阻燃效果且没有含卤阻燃剂和含磷阻燃剂,是一种新型的环境友好产品。

Preparation of heat-shrinkable materal with low-smoke, halogen-free, phosphor-free and flame-retardant by irradiation crosslinking was described in this paper. The effects of the matrix resin, the kinds and contents of coupling agent, fire retardant and radiation dose on shrinkage and mechanical properties were studied. The heat-shrinkable products , which were charaterized by good flame resistance, halogen-free and phosphor-free, were environmentfriendly products.
