Abstract

The invention disclsoes a hot-melt adhesive shoe lining and a preparation method thereof. The hot-melt adhesive shoe lining is prepared from the following raw materials in parts by weight through mixing, internal mixing, open mixing, rolling and then fitting with base cloth: a thermoplastic polyurethane (TPU) elastomer, polycarbonate (PC) resin, annular polybutylene terephthalate, water white rosin pentaerythritol ester, polyphenoxyl resin, 651 low molecular weight polyamide, a fluorinated ethylene-propylene copolymer, diallyl phthalate, dibutyltin dilaurate, hemp-fibered plaster, spherical ground quartz, wool wax, 4-tert-butylcatechol, ascorbyl palmitate and a solvent. The TPU, the PC, the annular polybutylene terephthalate and the polyphenoxyl resin have relatively good solubility and stability in the presence of the water white rosin pentaerythritol ester, the diallyl phthalate and the like; the toughness and impact strength of a traditional TPU hot-melt adhesive can be improved, the high-temperature resistance, creep resistance and wearing resistance of the traditional TPU hot-melt adhesive are improved, and the shoe lining is prevented from deforming and cracking.

Description

technical field [0001] The invention relates to the technical field of shoe lining preparation, in particular to a hot-melt rubber shoe lining and a preparation method thereof. Background technique [0002] my country is a big country in the production of shoes. With the improvement of people's living standards, people have higher and higher requirements for the maintenance of shoes. During daily use, shoes are prone to water absorption, swelling, deformation and wrinkling, which affects the appearance of shoes. and comfort. Therefore, people are often accustomed to using shoe linings to maintain the shape of shoes. However, shoe linings currently on the market are prone to softening and shrinking after a period of use, and the effect of shape retention decreases, and even degumming occurs, which shortens the use of shoe linings. Life span affects the quality and grade of shoes. [0003] In recent decades, hot-melt adhesives have been widely used due to their convenient use...
