Abstract

The invention relates to a rubber adhesive, and discloses a crack-resistant plastic shoe and a preparation method thereof. The preparation process of the invention improves the dispersion of raw materials in the adhesive. Moreover, epoxy groups are introduced into a chloroprene rubber and styrene-butadiene-styrene block copolymer, thereby improving the adhesion of the adhesive with the bonded rubber or plastic. On the other hand, an adhesive with higher stickiness and durability is obtained in conjunction with a composition B containing nitroso-fluororubber raw rubber, butyl acrylate, a crosslinking agent, magnesium oxide and zinc oxide. The adhesive has the advantages of simple preparation method, adoption of readily-available raw materials and higher popularization and application value.By applying the adhesive with high and persistent stickiness, the defects of weak and insufficient stickiness of the adhesive in the prior art are overcome. The anti-cracking plastic shoe is simple in preparation method.

Description

technical field [0001] The invention relates to an adhesive, in particular to a crack-resistant plastic shoe and a preparation method thereof. Background technique [0002] Due to the particularity of the environment in which plastic shoes are used, the adhesive requirements for rubber shoes are relatively high. Otherwise, it is easy to cause cracks at the joint between the upper and the sole. [0003] Rubber adhesives are widely used in the preparation process of rubber products. As a kind of rubber adhesives, neoprene adhesives are also commonly used in plastic adhesives, but the chlorine used in the prior art Butadiene rubber adhesives are usually a single combination of chloroprene rubber and solvents. Therefore, in the process of bonding rubber products, especially in the process of bonding different rubber products, it often leads to weak bonds and easy loosening. The bonding effect is poor, and the product quality is also greatly affected. [0004] Chinese patent ap...
