采用熔融共混法 ,探寻了高密度聚乙烯 /纳米氧化锌的耐光老化性能和拉伸性能 ,少量纳米氧化锌的加入可使材料耐光老化性能提高 3倍以上 ,同时使材料的拉伸强度和断裂伸长率得到提高 ,纳米氧化锌含量超过 5 %时 ,对力学性能产生不利影响。
The melt-blending method was used to explore the light-aging resistance and tensile properties of high-density polyethylene / nano-ZnO. The addition of a small amount of nano-ZnO increased the light aging resistance of the material by more than 3 times, Elongation at break is improved. When the content of nano-ZnO exceeds 5%, the mechanical properties will be adversely affected.
