自然气候老化对木塑地板性能的影响
Natural Weathering Effects on the Performance of Wood-Plastic Flooring
摘要
Abstract
The high density polyethylene (HDPE )and the wood powder (rubber wood flour or annatto pow-der)are used as the main raw material for the study and added with 0. 3% of UV absorbers (UV-531 or UV-1), extrusion molding them for PE based wood-plastic floor.1 80 days observation was made for natural weathering effects on wood-plastic floor′s performance in Kunming and Xishuangbanna.The results showed that:The 180-day natural weathering reduce the wood-plastic floor′s bending performance,high temperature and exposure to the sun is one of the main reasons;The surface color changes with the Natural weathering exposure,adding proper UV ab-sorber fitting with wood powder raw material can effectively improve the fastness of surface color in wood-plastic floor;The heavy rainfall will increase the water absorption rate of wood-plastic flooring,adding UV absorbers can enhance water resistance of wood-plastic flooring.关键词
