Ultra-lightweight and high wear-resistant rubber-plastic sole and preparation process thereof

Abstract

The invention relates to an ultra-lightweight and high wear-resistant rubber-plastic sole and a preparation process thereof. The ultra-lightweight and high wear-resistant rubber-plastic sole is prepared from the following two components in parts by weight: 70-80% of rubber-plastic composition and 22-28% of rubber-plastic auxiliary agent. The rubber-plastic composition is prepared from 65-70% of ethylene-vinyl acetate copolymer (EVA), 15-18% of isoprene rubber (IR), and 15-18% of block olefin copolymer (BOC); and the rubber-plastic auxiliary agent is prepared from 48-52% of anti-wear agent, 22-28% of filler, 1.2-1.8% of vulcanization accelerator, 2.2-2.8% of vulcanization active agent, 3-4% of active agent, 2.0-2.5% of cross-linking agent, 7.5-9.0% of foaming agent and 7-8% of chromogenic agent. The preparation process of rubber particles comprises the steps of putting the rubber-plastic composition and the rubber-plastic auxiliary agent except for the foaming agent and the cross-linking agent according to a formula amount into an internal mixer for mixing, then adding the foaming agent and the cross-linking agent, and subjecting the mixture to smelting, tableting, and extrusion granulation to form ultra-lightweight and wear-resistant rubber-plastic particles; the molding process of the sole comprises injection molding and vulcanization molding based on a mold.

Description

technical field [0001] The invention relates to a shoe sole, in particular to an ultra-light and highly wear-resistant rubber and plastic shoe sole and a preparation process, belonging to the technical field of polymer materials. Background technique [0002] Shoes are an article that can be worn on the feet based on the sole to prevent the feet from being hurt. It is an article made of leather, cloth, wood, grass, plastic, etc. and worn on the feet to land on the ground. Essential daily necessities, this is the general interpretation of shoes. However, in today's modern civilization, many functional elements have been added to shoes in the traditional sense, such as casual shoes, sneakers, hiking shoes, running shoes, dancing shoes, etc., all of which are "items for landing" On the basis of , specific functional attributes are added. Modern shoes have added various functional elements. How to make these additional functional elements better is a never-ending and challengi...
