环保型田菁胶胶黏剂的研究
|
摘要
以田菁胶、聚乙烯醇为主要原料,水为溶剂,通过加入氧化剂、糊化剂、交联剂,再辅以催干剂、抗冻剂、消泡剂等,制备出改性田菁胶胶黏剂。采用单因素实验,考察了氧化剂种类、氧化剂用量、糊化剂用量、交联剂用量等因素对产品性能的影响,优化出产品的最佳合成工艺。结果表明,最佳的合成工艺为水140 g,田菁胶10 g,氧化剂1.5 g,糊化剂0.33 g,交联剂0.0185 g,氯化钙2 g、抗冻剂、消泡剂适量。在此条件下合成的产品黏度为60~70 Pa·s。
Using sesbania gum and polyvinyl alcohol as raw materials, water as solvent, a kind of modified starch adhesive was prepared by adding oxidant, pasting agent, cross-linking agent, drier, antifreeze, antifoaming agent etc. By single factor experiment, the effects of the factors such as species of oxidant, mass of oxidant, mass of pasting agent and mass of cross-linking agent on the properties of the product were investigated. The results showed that the optimum parameters were water 140 g, sesbania gum 10 g, oxidant 1.5 g, pasting agent 0.33 g, cross-linking agent 0.018 5 g, calcium chloride 2 g, and appropriate ethanol and antifoaming agents. Under this condition, the product viscosity was 60~700 Pa.s.
