Novel high-resilience foamable rubber shoe sole material and preparation method thereof

Abstract

The invention discloses a novel high-resilience foamable rubber shoe sole material and a preparation method thereof. The material is characterized of being prepared from, by mass, 10-15% of chloroprene rubber, 8-12% of natural rubber, 10-15% of ethylene-vinyl acetate copolymer, 20-25% of butadiene rubber, 6-12% of butadiene styrene rubber, 5-10% of ethylene propylene diene monome, 5-12% of white carbon black, 3-6% of naphthenic oil, 0.5-1.5% of resin, 1-3% of an active agent, 1-3% of a foaming agent, 1-3% of a modified flowable agent and 0.5-1.5% of a bridging agent. The preparation method comprises the steps of material compounding, banburying, mixing, open milling, stamping and vulcanization, so that a finished product is obtained. According to the novel high-resilience foamable rubber shoe sole material and the preparation method thereof, the characteristics that compatible and complementary elements exist among all types of rubber raw materials are utilized, the novel foamable rubber shoe sole material having the mechanical properties such as high resilience, high abrasion resistance and low weight is obtained, and the material is widely applied to the field of rubber shoe sole manufacturing.

Description

technical field [0001] The invention relates to the technical field of rubber sole material and its preparation, in particular to a novel foamable rubber sole material with high resilience and a preparation method thereof. Background technique [0002] With the improvement of people's life requirements, the development of today's shoe material technology and the quality are constantly required to be improved. The functionality of the sole directly restricts the quality of the shoe material, such as comfort, light weight, wear resistance, high elasticity, and low permanent compression. The sole of the shoe is more and more sought after by people. [0003] At present, the main materials of sole materials on the market are polyvinyl chloride (PVC), ethylene-vinyl acetate copolymer (EVA), polyurethane (PU) and styrene-butadiene-styrene block copolymer (SBS). . PVC soles are cheap, but they are not wear-resistant and cold-resistant, especially in winter, they are easy to break;...

AI Technical Summary

Problems solved by technology

PVC soles are cheap, but they are not wear-resistant and cold-resistant, especially in winter, they are easy to break; EVA has disadvantages such as not being puncture-resistant, hardening at low temperatures, and poor slip resistance, and its wet-slip resistance becomes worse after contact with water ; PU has good mechanical properties, but its low temperature performance is poor, easy to hydrolyze and biodegrade, difficult to process, and complicated in process; SBS also has some shortcomings, such as poor wear resistance and heat resistance, and the sole has a large grip on the ground. High heat generation under extreme wearing conditions, and the sole wears out quickly
