Abstract

The invention provides a burning resistant conveyor belt. The burning resistant conveyor belt is prepared from the raw materials of 55-65 parts of natural rubber, 5-15 parts of butadiene rubber, 25-35parts of styrene butadiene rubber, 2-4 parts of zinc oxide, 0.5-1.5 parts of stearic acid, 4-6 parts of an antiager, 50-60 parts of super wear-resistant carbon black, 25-35 parts of a carbon formingagent, 1-3 parts of sulfur and 2-3 parts of an accelerant. Through the mixing use of the natural rubber, the butadiene rubber and the styrene butadiene rubber, and the addition of the carbon forming agent, the burning resistant performance of conveyor belt products is greatly improved, and under the harsh working conditions of steel plants, power plants and the like, the requirements of instantaneous and short-term use can be met.

Description

technical field [0001] The invention relates to the field of conveyor belt materials, in particular to a burning-resistant conveyor belt. Background technique [0002] With the continuous improvement of productivity, the demand for conveyor belts in steel mills, power plants and other enterprises is increasing. 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. The higher, especially 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 material will soon crack and wear under the condition of 300°C with an open flame, so it becomes very important to solve this problem. Contents of the invention [0003] The purpose of the present invention is to provide a burning-resistant conveyor belt, which is mixed with natural rubber, b...
