Processing method of continuous injection shoe sole material, the material, and continuous injection shoes and processing method

Abstract

The invention provides a continuous injection shoe sole material and a processing method thereof. The continuous injection shoe sole material is prepared by mechanical mixing of a hard material and a soft material. The hard material is prepared by the melt extrusion and the granulation of oil filled rubber, polystyrene, K resin, polyphenylene ether, maleic anhydride modified propylene-based elastomer, and / or heavy calcium powder. The soft material is prepared by the mixing smelting and the granulation of oil filled rubber, methyl vinyl silicone rubber, C5 petroleum resin, foaming agent AC and expandable microsphere foaming agent. The oil filled rubber is prepared by mixing styrene-butadiene- styrene triblock copolymer and softening oil. The invention further provides a continuous injection shoe and processing method thereof. The prepared continuous injection shoe sole material has the following advantages that shoe surface and shoe sole can be formed by direct injection, and the continuous injection shoe sole material has the advantages of being light in weight, wear resistant, cold resistant, good in processing performance, and high in production efficiency, recyclable and environmental friendly and the like.

Description

technical field [0001] The invention belongs to the field of shoe sole material processing, and in particular relates to a processing method of upper injection sole material, the material, upper injection shoes and a processing method. Background technique [0002] The comfort level, service life, and special functions of shoes are all related to the performance of sole materials to a large extent. Ordinary shoe soles are not environmentally friendly because the preparation materials contain chlorine, lead, and polycyclic aromatic hydrocarbons. The soles produced from ordinary sole materials cannot be directly injection molded due to their poor compatibility with the upper, which leads to the use of adhesives in the manufacturing process of shoes. The use of adhesives not only makes the production The process is complicated and the production cost is increased, and some adhesives contain toxic and harmful substances, which do not meet the standards of green environmental pr...

AI Technical Summary

Problems solved by technology

The soles produced from ordinary sole materials cannot be directly injection molded due to their poor compatibility with the upper, which leads to the use of adhesives in the manufacturing process of shoes. The use of adhesives not only makes the production The process is complicated and the production cost is increased, and some adhesives contain toxic and harmful substances, which do not meet the standards of green environmental protection

The cooling rate of ordinary shoe materials is small, and the cooling time is long. After the shoe is formed, it takes a long time to cool down and cool down, resulting in low production efficiency of the shoe.

Ordinary shoe materials also have defects such as heavy weight, poor wear resistance, no cold resistance, poor processing performance, and non-recyclable
