卷材涂料用高加工聚酯树脂的研制

Study on the Synthesis of Polyester Resin for Rapid Curingcoil Powder Coating

本文通过对原材料的筛选和认定,研制了合成了数均分子量在6000左右的两支微分支化聚酯树脂,通过含烷基的二元醇、6C以上长碳链二元醇及二元酸的配合使用,制得了高硬度、高加工性、光泽及耐碱优良的饱和聚酯树脂。

Through to select and identify the raw materials, this article was investigated and synthesized two differential branched polyester resin which average molecular weight is around 6000. To cooperate with dihydric alcohol contains alkyl, dihydric alcohol with 6 C long carbon chain and dibasic acid, synthesized saturated polyester resin which has the high hardness, good machinability and have excellent gloss and alkali resistant.
