摘要
研究了受阻酚抗氧剂种类及含量、受阻酚抗氧剂与亚磷酸酯类抗氧剂复配以及亚磷酸酯抗氧剂对聚酯粉末涂料耐气熏黄变性能的影响。结果表明:使用了168的涂层耐黄变性能最佳,1076、1010与168复配耐黄变性能其次,1076、1010再次,1098最差。经过红外光谱分析,1076在氮氧化物氛围中生成了C=O、N=O等生色团,从而影响了其耐黄变性能。
The effects of the type and content of hindered phenol anti-oxidant, the compound of hindered phenol anti-oxidant and phosphite anti-oxidants on the yellowing resistance of powder coatings were studied. The results showed that the anti-yellowing property of the anti-oxidant 168 was the best, the 1098 were the worst. The anti-oxidant 1076 generated chromophore group such as C=-O and N=O in nitrogen atmosphere through infrared spectrum analysis, which affected its anti-yellowing property
