摘要
将核壳结构CuO@γ-Al2O3复合粒子催化剂加入到低烟无卤阻燃聚烯烃材料中,制备了低烟气、毒性低、无卤阻燃聚烯烃复合材料,考查了复合粒子催化剂对复合材料的燃烧烟气毒性、阻燃性能、机械物理性能、耐臭氧性能、热老化性能、耐油性能和耐酸碱性能等的影响.结果显示,核壳结构催化剂的加入可降低复合材料的烟气毒性,并使复合材料的机械物理性能、热老化性能和耐油性能下降,而对材料的阻燃性能和耐酸碱性能影响不大.
Abstract
This article discusses the core-shell structure of CuO@γ-Al2O3 composite particle catalyst was added to low smoke halogen-free flame retardant polyolefin materials to prepare low smoke toxicity low smoke halogen-free flame retar-dant polyolefin composite materials. The effects of the composite particle catalyst on the combustion smoke toxicity,flame retardant performance,mechanical and physical properties,ozone resistance,thermal aging performance,oil resistance,and acid-base resistance of the composite materials were investigated. The results show that the addition of core-shell struc-ture catalysts can reduce the smoke toxicity of composite materials,and reduce the mechanical and physical properties,thermal aging properties,and oil resistance of the composite materials,while having little effect on the flame retardant per-formance and acid alkali resistance of the materials.
