Abstract

The invention discloses a pair of protective boots and a manufacturing method thereof. The sole of each of the pair of protective boots comprises a boot insole which is made from a polyurethane material, a boot outsole which is made from a rubber material and a flank supporting piece which is made from a rubber-plastic material; the upper of the protective boot and the boot outsole are connected by virtue of the boot insole which is formed by injecting the polyurethane material; the upper of the protective boot and the flank supporting piece are connected by virtue of the boot insole which is formed by injecting the polyurethane material; the flank supporting piece is arranged on an arch part on the outer side of the boot insole. The protective boots disclosed by the invention are light in weight, soft, elastic and shock-absorbing; and the boots, which are injection-molded in an upper-joint mode, are firm and wear-resistant, and the manufacturing method is efficient in processing technique and low in manufacturing cost.

Description

technical field [0001] The invention relates to a protective boot and a preparation method thereof. Background technique [0002] Polyurethane material is the abbreviation of polyurethane, the English name is polyurethane, it is a kind of polymer material. Polyurethane is an emerging organic polymer material, known as the "fifth largest plastic", and is widely used in many fields of the national economy because of its excellent performance. The product application fields involve light industry, chemical industry, electronics, textile, medical treatment, construction, building materials, automobile, national defense, aerospace, aviation and so on. It is often used as the inner and outer soles of shoes in the preparation of footwear industry, but the wear resistance of polyurethane materials in the prior art cannot achieve the effect of wear resistance, and can not realize the characteristics of light weight at the same time. [0003] Early rubber was latex taken from plants...
