Sizing material for rubber shoe sole and preparation method thereof

Abstract

The invention discloses a sizing material for a rubber shoe sole and a preparation method thereof. The sizing material comprises the following raw materials for preparing active ingredients in parts by weight: 100 parts of rubber, 1.2-2.5 parts of sulfur, 2-5 parts of zinc oxide, 1-2.5 parts of stearic acid, 1-3 parts of a medium-speed accelerant, 0.3 part of a high-speed accelerant, 1.5-3 parts of an anti-ageing agent, 35-55 parts of carbon black, 5-10 parts of softening oil, 25-35 parts of rubber powder and 1-1.5 parts of coupling agent. The preparation method comprises the following steps of: pretreating the rubber powder; plastifying rubber; compounding; milling, and the like. The rubber shoe sole produced by using a rubber powder formula and the preparation method thereof has the advantages of reduction in the tensile strength change rate by 3-5 percent, reduction in the tensile yield change rate by 5-8 percent, the same wear resistance and bending resistance as those of a rubber shoe sole produced without using rubber powder in the same type of products, smooth appearance handfeel, soft brightness and increase in grade. The sizing material is suitable for preparing rubber shoe soles of dress shoes and outdoor shoes.

Description

technical field [0001] The invention belongs to the field of rubber products and relates to the reuse of waste rubber, in particular to a rubber material for rubber soles. technical background [0002] With the increasing use of rubber materials in my country, the problem of disposal of waste rubber products is becoming more and more prominent. If they are not properly utilized, it will not only cause a great burden on the environment, but also cause a waste of resources. [0003] At present, there are two ways to recycle waste rubber materials: one is to make rubber powder for the modification of construction asphalt, etc.; the other is to make reclaimed rubber, which is used as a low-grade additive material for the production of rubber products. Rubber powder is a powdery rubber material obtained by crushing and processing rubber products. Generally, rubber powder is mainly used in low-grade products, and is widely used in sports plastic playgrounds, playgrounds, rubber fl...

AI Technical Summary

Problems solved by technology

[0005] 1. In the process of producing reclaimed rubber from waste rubber, environmental pollution such as waste water and waste gas will be generated;

[0006] 2. Reclaimed rubber is mainly used in the production of low-grade rubber products, and rubber powder is mainly used in the construction field, which limits the scale and efficiency of rubber recycling to a certain extent, thus affecting the enthusiasm for waste rubber treatment and production
