Problems solved by technology

At present, during the long-term wearing of sports shoes, the powdery compounding agents such as vulcanizing agents, accelerators, active agents, anti-aging agents, and wear-resistant agents in the sole rubber raw materials are easy to precipitate on the surface of the rubber, resulting in yellowing of the rubber surface, and with time. The longer the wearing time, the more serious the phenomenon of yellowing of the rubber, which seriously affects the appearance of the sports shoes and reduces the wear resistance of the soles

Abstract

The invention relates to a wear-resistant sole preparation process, which comprises: S1, colloidal particle raw material preparation: adding a rubber and plastic composition and an auxiliary agent to an internal mixer, adding a foaming agent and a cross-linking agent, carrying out mixing through a calender, and carrying out open milling, sheet discharging and extrusion granulation to form rubber and plastic colloidal particles; S2, injection molding: putting the rubber-plastic colloidal particles into a lower mold, putting the pretreated alloy particles onto the upper surface of the rubber material according to the mass ratio of the alloy particles to the rubber material of 1: (10-15), and covering the upper mold; and pushing the mold into a press machine for vulcanization molding to obtain the wear-resistant rubber sole. According to the invention, the alloy particles are doped into the rubber-plastic colloidal particles, the vulcanized sole has high toughness and high wear resistance, and the composition of the rubber-plastic colloidal particles comprises the small molecular rubber and the block copolymer, and large and small molecules are mixed, so that the elasticity of the rubber is increased, and the comfort of the sole is improved.

Description

technical field [0001] The invention relates to the technical field of shoe preparation, in particular to a preparation process for wear-resistant shoe soles. Background technique [0002] Rubber is the number one sole material in the world and can be used as the base material of sports shoes. Natural rubber has high elasticity at room temperature, slightly plastic, has very good mechanical strength, low hysteresis loss, and low heat generation during multiple deformations, so its flex resistance is also very good, and because it is non-polar Rubber, so the electrical insulation performance is good, the advantage of natural rubber is that it is very soft, excellent elasticity, has a certain anti-skid performance, and can be suitable for various sports. At present, during the long-term wearing of sports shoes, the powdery compounding agents such as vulcanizing agents, accelerators, active agents, anti-aging agents, and wear-resistant agents in the sole rubber raw materials a...
