摘要
添加了抗氧化剂的TGIC副产物经蒸馏,得到较纯净的副产物,并将其与热熔胶黏剂按一定比例混合,得到一种复合胶黏剂。分析了副产物与热熔胶黏剂的配比对持黏性、T—剥离强度、180°剥离强度、软化点、熔融黏度的影响。当TGIC副产物与热熔胶黏剂的配比为2∶8时,所制备胶黏剂的主要力学、理化指标仍能满足家具封边、胶订等领域的行业标准的要求。TGIC副产物在热熔胶黏剂中的应用,不仅降低了产品的成本,减少了环境污染,而且熔融黏度的降低,使得操作难度也大大降低,继而节省了操作成本。
After distilling the TGIC by-products with antioxidant added in, the pure by-products were obtained. A kind of compound adhesive was synthesized by mixing this pure by-product and hot melt adhesive with a certain mixing ratio. The effects of mixing ratio of by-products to hot melt adhesive on the holding viscosity, T-peel strength, 180~ peel strength, softening point and melting viscosity were analyzed. When the ratio of TGIC by-products to hot melt adhesive was 2：8 ,the key mechanical, physical and chemical index of prepared adhesive could still meet the normative requirement of furniture edge sealing and adhesive binding. The application of TGIC by-products in hot melt adhesive had reduced both the products cost and the environmental pollution. And as the melting viscosity reducing, the operation difficulty and cost also decreased.
