摘　　要：介绍了一组基于间苯二甲酸单体制备的高、低酸值耐候端羧基聚酯树脂，以该树脂制备的粉末涂料通过干混后静电喷涂可获得良好的消光效果（光泽为21～26），涂膜外观细腻，耐候性卓越，耐老化时间明显比对照样的长。This article has described the preparation of a carboxyl-terminated polyester resin based on isophthalic acid for two-component matting super durable powder coatings. The prepared powder coating showed a matting effect with only 21- 26 gloss. The coating was fea- tured by its lower gloss, smooth appearance and outstanding weather durability.
