摘要
研究了聚氨酯弹性体于紫外光(UVC)下的耐黄变特性,比较了二氧化钛(TiO2)与紫外线吸收剂等不同添加剂对白色聚氨酯弹性体耐UVC特性的影响。结果表明,影响黄变最大的因素为聚氨酯树脂,其次为TiO2与紫外线吸收剂。
The characteristics of the polyurethane material in the yellowing of the UVC weathering were re- searched. The effects of various additional agents in raw materials on white polyurethane resistence UVC were com- pared, including TiO2 and ultraviolet absorbent. The results showed that the affect of yellowing largest factor was polyurethane resin, followed by the titanium dioxide and UV absorbers.
