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。
The TGIC by-product with added antioxidants is distilled to obtain purer by-products, which are mixed with the hot melt adhesive in a certain ratio to obtain a composite adhesive. The effects of the ratio of by-products and hot melt adhesive on the tackiness, T-peel strength, 180 ° peel strength, softening point and melt viscosity were analyzed. When the ratio of TGIC byproduct and hot melt adhesive is 2: 8, the main mechanical and physical and chemical indexes of the prepared adhesive can still meet the requirements of industry standards in the fields of furniture edge sealing and glue binding. The application of TGIC byproduct in hot melt adhesive not only reduces the cost of the product and reduces the environmental pollution, but also reduces the melt viscosity and greatly reduces the operation difficulty, thereby saving the operation cost.
