高温固化型酯化改性木薯淀粉胶粘剂及其制备方法
摘要：
高温固化型酯化改性木薯淀粉胶粘剂及其制备方法，它属于胶黏剂制备技术领域。目前木材工业中普遍使用的胶粘剂的原料均不可再生。本发明主要是由改性木薯淀粉胶粘剂、异氰酸酯、抗氧剂、阻燃剂、光稳定剂、紫外线吸收剂制成，其重量份数分别为80～100份的改性木薯淀粉胶粘剂、7～12份的异氰酸酯、0.5～1.5份的抗氧剂、0.5～2份的阻燃剂、0.02～0.2份的光稳定剂、0.5～1份的紫外线吸收剂，其中改性木薯淀粉胶粘剂的成分包括木薯淀粉、聚乙烯醇、十二烷基硫酸钠、十二烯基丁二酸酐。本发明粘度适中，储存稳定，分层慢，制备工艺简单易操作，耗时短；耐水性能优良，胶合强度优异，易于实现工业化生产。
摘要（英）：

The invention provides a high-temperature cured type esterification modified cassava starch adhesive and a preparation method thereof and belongs to the technical field of adhesive preparation. At present, raw materials of adhesives generally used in the wood industry are non-renewable. The high-temperature cured type esterification modified cassava starch adhesive is mainly prepared from, by weight, 80-100 parts of modified cassava starch adhesive, 7-12 parts of isocyanate, 0.5-1.5 parts of antioxygen, 0.5-2 parts of flame retardant, 0.02-0.2 part of light stabilizer and 0.5-1 part of ultraviolet light absorber, wherein the modified cassava starch adhesive comprises cassava starch, polyvinyl alcohol, sodium dodecyl sulfate and dodecenyl succinic anhydride. The high-temperature cured type esterification modified cassava starch adhesive is moderate in viscosity, stable in storing and slow in layering. The preparation process is simple and easy to operate. The consumed time is short. The high-temperature cured type esterification modified cassava starch adhesive is excellent in water resistant performance and bonding strength, and industrial production is likely to be realized.
