Abstract

The invention discloses a preparation method of high-temperature resistant conveying belt covering glue. The high-temperature resistant conveying belt covering glue comprises the following components in parts by weight: 30-50 parts of ethylene propylene diene monomer rubber, 40-70 parts of butadiene styrene rubber, 40-80 parts of reinforcing fillers, 2.5-8 parts of a vulcanizing agent, 0.2-8 parts of a vulcanizing accelerator, 2-20 parts of a vulcanizing activator, 5-10 parts of a coupling agent, 5-35 parts of a plasticizer and 1-5 parts of anti-aging agent. The preparation method comprises the following steps: (1) primarily mixing; and (2) secondarily mixing. The preparation method has the beneficial effects that a high-temperature severe environment in an sintered ore workshop can be adapted, the cost of the high-temperature resistant conveying belt is lowered, the service life of the high-temperature resistant conveying belt is prolonged, and the economic efficiency and the experience benefit of an enterprise are increased; the preparation method is suitable for being generally popularized and used.

Description

Technical field: [0001] The invention relates to the technical field of wood conveyor belts, in particular to a method for preparing high temperature resistant conveyor belt covering rubber. Background technique: [0002] EPDM rubber is a carbon chain saturated non-polar rubber. It does not react with strong oxidants, strong reducing agents, strong acids, and strong bases at room temperature, and is not easily polarized. It is an ideal high temperature resistant covering rubber material. Nowadays, many high-temperature resistant covering rubber materials are EPDM rubber. Single use of EPDM rubber not only has poor adhesion performance, but also causes delamination of the cover rubber, and the processing performance of EPDM rubber is poor, which affects production. Efficiency, the most important thing is that EPDM rubber has a higher cost and a small profit margin. Summary of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the prior a...
