摘要
将双醛淀粉(DAS)与聚乙烯醇(PVA)进行缩合反应,探讨了DAS-PVA胶粘剂合成的最佳条件。结果表明,最佳合成工艺条件为:DAS与PVA摩尔比1∶1,温度95℃,pH值2.0,硼砂用量2.0%。经测试,该胶粘剂的黏度为1.3 Pa.s,游离甲醛含量0.001%,符合绿色环保要求。
Discussions were made on optimal conditions for condensation reaction between dialdehyde starch (DAS) and PVA to form DAS-PVA glue. The result showed that the optimal process conditions for synthesis were as follows: tool ration of DAS/ PVA 1: 1, temperature 95 ~C, pH 2.0, and dosage of borax 2.0%. Test showed that the viscosity of glue was 1.3 Pa·s,cantent of free formaldehyde was 0.001%,that meet the requirement for green environmental production.
