Abstract

The invention discloses a high-temperature-resistant conveyor belt covering rubber and development method thereof. The covering rubber comprises the following materials by mass: 100 parts of a thermoplastic elastomer containing ethylene chain segments, 15 to 30 parts of a plasticizer, 5 to 10 parts of an activator, 1 to 2 parts of stearic acid, 3 to 5 parts of an anti-aging agent, 10 to 20 parts of a heat-resistant auxiliary agent, 3 to 5 parts of a peroxide cross-linking agent and 0.5 to 3 parts of a cross-linking aid. The main rubber of the covering rubber is the thermoplastic elastomer containing the ethylene chain segments; carbon black is used as a reinforcing agent of the covering rubber; the plasticizer is a high-temperature-resistant material; the anti-aging agent is an antioxidant anti-aging agent; and the peroxide cross-linking agent is employed. According to the development method, the covering rubber can be prepared by carrying out mixing according to a formula under suitable temperature conditions; and the prepared covering rubber can be used for a long time at a high temperature of 200 DEG C, the transient temperature of the covering rubber can reach 300 DEG C, all the mechanical properties and physical and mechanical properties of the covering rubber meet usage requirements on conveyor belts, and the cost of the covering rubber is 2-3 yuan/Kg lower compared with traditional ethylene-propylene rubber compounds.

Description

technical field [0001] The invention relates to a high-temperature-resistant conveyor belt cover glue and a development method thereof, belonging to the technical field of polymer materials. Background technique [0002] With the rapid development of metallurgy, casting, sintering, coking, and building materials industries, conveyor belts need to work in more harsh high-temperature environments, and sometimes need to transport materials at 200°C or even higher temperatures; traditionally used EPDM rubber can be used for a long time The heat resistance is 125 degrees, and the short-term heat resistance is 150 degrees, which can no longer meet the requirements of use. Customers need to replace the conveyor belt regularly, which not only wastes time, but also costs a lot. Contents of the invention [0003] The purpose of the present invention is to improve the heat-resistant temperature of the conveyor belt, and provide a conveyor belt cover rubber with low cost, good heat re...
