Preparation method of protective sole material

Abstract

The invention discloses a preparation method of a protective sole material, which comprises the following steps: adding 100-105 parts by mass of HDPE (high-density polyethylene), 70-80 parts by mass of PP (polypropylene) powder, 16-22 parts by mass of PET (polyethylene terephthalate), 8-9 parts by mass of PE (polyethylene) wax, 3-6 parts by mass of lead stearate, 6-8 parts by mass of sodium benzoate, 3-6 parts by mass of spherical silicon dioxide and 7-8 parts by mass of PA 6 (polyamide 6) into a high-speed mixing machine, and mixing for 10 minutes; and adding the mixture into a double screw extruder, and carrying out melt grafting for 3 hours to obtain the sole material. The method disclosed by the invention has the advantages of simple preparation technique and low production cost; and the protective sole material has the advantages of high elasticity, favorable electric insulativity, high temperature resistance and light weight, and is comfortable.

Description

technical field [0001] The invention relates to a preparation method of a protective shoe sole material. technical background [0002] On construction sites, there are often some nails or other sharp objects on the ground. If construction workers accidentally step on them, they will be pierced through the soles of their feet and even cause bacterial infections. At present, most of the puncture-resistant shoes on the market add a layer of steel plate or other hard plates to the soles. Although they are not easy to be punctured, such shoes increase the weight, and people will be very tired when wearing them. In recent years, with the advancement of science and technology, the use of sole materials has become more and more extensive. At present, most of the sole materials on the market are synthetic rubber. In order to adapt to different working environments, the performance of synthetic rubber is further improved.
