摘要

研究了10 ~ 40%的天然填料(南瓜皮、豆渣、松木屑)对LDPE的力学性能和可燃性的影响。随着填料含量的增加，硬度略有升高，抗拉强度和相对伸长率下降。拉伸模量增加一倍以上(南瓜皮、松木屑)。线性燃烧率增加不利，但假定的可燃性等级HB40达到，除了填充40 wt%松木屑(HB75)的LDPE。同时，在垂直可燃性试验中，燃烧区温度降低。

The effect of natural fillers on the mechanical properties and flammability of low-density polyethylene

The effect of 10-40 wt% natural fillers (pumpkin husks, bean sorting waste, pine sawdust) on the mechanical properties and flammability of LDPE was examined. As the filler content increased, the hardness slightly increased and the tensile strength and relative elongation decreased. The tensile modulus more than doubled (pumpkin husks, pine sawdust). The linear combustion rate increased unfavorably, but the assumed flammability class HB40 was achieved, except for LDPE filled with 40 wt% pine sawdust (HB75). At the same time, the temperature in the combustion area decreased in the vertical flammability test.
