制备了一种防绿化优良的不饱和聚酯树脂,试验结果表明,在树脂合成过程中引入5%～9%的改性剂,合成的树脂具有优良的气干性,而且柔韧性和防绿化性大为提高,满足涂料用不饱和聚酯树脂的要求。
An excellent anti-greening unsaturated polyester resin was prepared. The experimental results show that 5% ~ 9% of modifier is introduced during the synthesis of resin, the synthesized resin has excellent air-drying property, and the flexibility and anti-greening Sex greatly improved to meet the coating with unsaturated polyester resin requirements.
