Problems solved by technology

Due to the oiliness of the material to be conveyed, when the ordinary conveyor belt is conveying oily materials, the covering layer is easily eroded into the conveyor belt by mineral oil, causing the conveyor belt to swell, so that the rubber on the conveyor belt falls off, which greatly shortens the Conveyor belt service life

Abstract

The invention relates to oil-resistant conveying belt covering rubber prepared from the following raw materials in parts by weight: 100 parts of butadiene-acrylonitrile rubber, 1-2 parts of a promoter, 1-2 parts of a vulcanizing agent, 4-6 parts of a vulcanization activator, 5-8 parts of a plasticizer, 8-12 parts of a softening agent, 20-60 parts of reinforcing filler, 12-18 parts of a filling agent and 2-4 parts of an anti-aging agent. The preparation method comprises the following steps: (1) plasticating the 100 parts of butadiene-acrylonitrile rubber in an open mill; (2) putting a plasticated rubber material into an internal mixer, sequentially adding the reinforcing filler, the vulcanization activator, the plasticizer and the anti-aging agent with the weight parts, stirring for a period of time, then adding the softening agent and the filling agent, continuously stirring, finally adding the vulcanizing agent and the promoter, and uniformly stirring to obtain mixed rubber; and (3) performing rubber sheet extrusion on the mixed rubber material by virtue of the open mill to obtain the oil-resistant conveying belt covering rubber. The oil-resistant conveying belt covering rubber disclosed by the invention adopts the butadiene-acrylonitrile rubber as a main raw material; and by adding reasonable compounding agents into the butadiene-acrylonitrile rubber, the oil resistance of the covering rubber can be effectively improved, and the service life of a conveying belt can be prolonged.

Description

[0001] technical field [0002] The invention belongs to rubber products, in particular to an oil-resistant conveyor belt covering rubber. Background technique [0003] Conveyor belt is the leading part of the conveyor used to carry and transport various solid block and powder materials, and has been widely used in coal, mining, electric power, metallurgy, light industry, grain and other fields, and has various forms. In recent years, with the rapid development of the national economy, especially the rapid development of the wharf, food and other industries, the oil-resistant conveyor belt has played an increasingly important role in the transportation of special materials such as grain and oil. Because the material to be transported is oily, when the ordinary conveyor belt is conveying oily material, the covering layer is easily eroded into the conveyor belt by mineral oil, causing the conveyor belt to swell, so that the rubber on the conveyor belt falls off, which greatly ...
