摘要/Abstract

摘要：

以豌豆淀粉为原料, 先用异淀粉酶处理, 再将酶化的淀粉进行醚化反应, 研究淀粉成膜剂的制备条件. 考察酶解时间、环氧丙烷用量、醚化
时间、反应温度和氢氧化钠用量对成膜剂的性能影响. 通过正交试验得到制备淀粉成膜剂的最优条件：酶解时间12 h, 环氧丙烷用量4 g, 醚化时间16 h, 反应温度45 ℃, 氢氧化钠用量0.4 g. 拉丝实验结果表明, 改性淀粉作为成膜剂用于玻璃纤维浸润剂, 可保证拉丝工艺顺利完成.

Abstract:

Pea starch was used as raw material to produce film forming agent in this study. The starch was processed by isoamylase firstly, and then the obtained product was subjected to hydroxypropylation. We studied the effects of enzyme reaction time, the dosage of propylene oxide, etherification time, reaction temperature and the dosage of sodium hydroxide on the performance of film forming agent. The reaction conditions were optimized via orthogonal test as follows: enzyme reaction time was 12 h, propylene oxide 4 g, reaction time 16 h, reaction temperature 45 ℃, sodium hydroxide 0.4 g. The results show that the modified product as the filmforming agent in glass fibre sizing could ensure the successful drawing process.

Key words: sizing, pea starch, etherification, filmforming agent
