低泛黄 MMA接枝改性豆油醇酸漆的研制

The preparation of a low yellowing MMA grafting soybean alkyd paint

研究了甲基丙烯酸甲酯 (MMA)改性豆油醇酸树脂对溶剂气干型醇酸白漆泛黄程度的影响。其结果是使用引发剂的量越高 ,最终改性树脂的不饱和程度就越低 ,配制的白漆泛黄速率也就越小。改性醇酸树脂白漆无论是在热加速老化还是NH3加速老化下都比普通油含量相当的醇酸白漆泛黄程度低。

MMA grafting is used to lowering the yellowing tendency of an soybean alkyd paint. The authors found that while more initiator were used in the preparation of the resin, the lower is the yellowing tendency of the modified paint. Same results are obtained under thermal accelerated aging and NH3 accelerated aging.
