摘要
研究了抗氧剂、紫外线吸收剂、异氰酸酯等对聚氨酯泡沫黄变的影响因素。选用合适原料,开发出了性能优良、变色等级为0(氙灯老化箱内加速老化502h)的耐黄变聚氨酯软泡。
The effects of antioxidant, UV-absorbents, isolyanates, etc. on yellowing of polyurethane flexibte foams were studied. The yellowing-proof polyurethane flexible foams with good properties arid yellowing index zero（accelerating aging 502h in xenon lamp aging box） were prepared by selecting suitable raw materials.
