Abstract

The invention relates to a preparation method of high-temperature resistant steel wire rope core conveying belt core glue. The core glue comprises the following raw material components in parts by weight: 100 parts of ethylene propylene rubber, 70-110 parts of reinforcing filler, 3-5 parts of vulcanizing agent, 5-11.5 parts of vulcanizing activator, 20-30 parts of plasticizer, 2-4 parts of anti-aging agent and 3.8-4.2 parts of adhesive, wherein the components are subjected to first-section mixing and second-section mixing to obtain high-temperature resistant steel wire rope core conveying belt core glue. According to the invention, the formula system of the high-temperature resistant steel wire rope core conveying belt core glue can realize a good effect; and after use, the high-temperature resistant steel wire rope core conveying belt core glue meets the requirement on high-temperature resistance of material conveying in a cement plant and a steel plant, prevents sharp fall of the adhesive force between the core glue and the steel wire rope caused by early aging of the core glue, greatly prolongs the service life of the conveying belt, and creates great economic benefits.

Description

technical field [0001] The invention relates to a preparation method of a high-temperature-resistant steel cord conveyor belt core rubber. Background technique [0002] The rapid development of China's economy in recent years has led to the rapid growth of basic industries such as steel and cement. The production scale and production capacity of the steel and cement industries have also increased sharply. At the same time, this also affects the ease of material transportation in the production of steel and cement industries. Consumables, but also key components - conveyor belts put forward more and higher requirements. [0003] The materials conveyed in the steel and cement industries have the characteristics of high temperature. Under special circumstances, the instantaneous temperature can reach 400~500°C, and the highest can reach 600°C. Good ethylene-propylene rubber is used as the covering rubber; for the core rubber of the conveyor belt, more natural rubber and styren...
