摘要
通过正交试验优化并验证了最佳Ⅰ、Ⅱ型淀粉基水性高分子一异氰酸酯API胶黏剂的配方及工艺，参照日本JIS K6806标准要求进行了主要性能测试，同时进行了生产性试验。结果表明，淀粉基API胶黏剂室温下活性期超过合成树脂基API胶黏剂；贮存稳定性室温下达到3个月。采用淀粉基API胶黏剂，分别用于胶合板、竹地板、实木复合地板、细木工板、胶合木等胶合制品的制造，其理化性能指标完全达到有关标准要求，并且制品无甲醛等有毒物质释放。此种胶黏剂具有明显的生产可操作性，完全满足现有的工艺要求，其原料成本为进口胶黏剂的1／4～1／3，具有明显的社会环境效益和经济效益。
The production test on the optimum formulation and technology of type Ⅰ ,Ⅱ starch-based API optimized by orthogonal test and validating test is conducted and the main properties of the API are tested according to JISK 6806 standard requirement. The results show that the pot life of starch-based API exceeds that of synthesized resin-based API and storage stability reaches 3 months at room temperature. The glued-products such as plywood, bamboo flooring, parquet flooring, blackboard and etc. are manufactured respectively by adopting starch-based API adhesive. Indices of physical and chemical properties reach completely relevant standard requirement and no deleterious matter as formaldehyde is released. Such adhesive has obvious operability in production and meets completely requirement for existing technology. Its raw materials cost is equivalent to 1/4- 1/3 of imported adhesive. So it has obvious social environment benefits and economical benefits.
