Abstract

The invention relates to conveyer belt covering rubber and a preparation method thereof and particularly relates to a 350 DEG G firing-resistant conveyer belt covering rubber and a preparation method thereof. The 350 DEG C firing-resistant conveyer belt covering rubber comprises the following components: 100 parts of butadiene styrene rubber, 3.5-8.5 parts of activating agent, 2.5-6.5 parts of anti-aging agent, 50-70 parts of carbon black, 3.5-5.5 parts of C9 petroleum resin, 2.5-4.5 parts of coumarone resin, 2.5-5.5 parts of dispersing agent, 1.0-5.0 parts of sulphur, 0.8-3.5 parts of vulcanization accelerator, 3.5-7.5 parts of 52# chlorinated paraffin and 8.0-16.0 parts of coking agent. The prepared 350 DEG C firing-resistant conveyer belt covering rubber can be used for conveying a material with the temperature of 350 DEG C, a rubber coked layer is formed on the surface of a conveyer belt body to take a thermal insulation protection effect, and therefore cracking and abrasion of a conveyer belt are avoided and the service life of the conveyer belt is prolonged. The 350 DEG C firing-resistant conveyer belt covering rubber product has good physical properties, low static electricity conductivity and excellent flame retardant property.

Description

technical field [0001] The invention relates to a conveyor belt covering glue and a preparation method thereof, in particular to a 350°C burning-resistant conveyor belt covering glue and a preparation method thereof. Background technique [0002] With the continuous improvement of productivity, industrial and mining enterprises such as steel mills have an increasing demand for conveyor belts. At the same time, because the ambient temperature of conveyor belts is getting higher and higher, even exceeding 800°C, the quality requirements for conveyor belts are getting higher and higher. Especially for the heat resistance and burning resistance of the covering glue on the working surface of the conveyor belt. However, the existing heat-resistant conveyor belt covering glue formula will soon crack and wear under the condition of 300°C with an open flame, and the service life is low. Contents of the invention [0003] The invention aims at the deficiencies in the prior art and ...
