Abstract

The invention relates to a surface covering glue for a high-temperature resistant wire rope core conveyer belt. The surface covering glue can resist a test temperature not higher than 175 DEG C and the highest short-time running temperature at 300 DEG C, and reaches the T4 level of GB/T20021-2005 standard. The surface covering glue for the high-temperature resistant wire rope core conveyer belt is prepared by the steps of mixing ethylene-propylene terpolymer, cumyl peroxide DCP, zinc oxide, Triallyl Isocyanurate TAIC, zinc methacrylic acid ZDMA, stearic acid, anti-aging agent RD, anti-aging agent MB, anti-aging agent 6PPD, N330 carbon black, N550 carbon black, coumarone and paroline, forming glue sheets, molding and finally vulcanizing. The surface covering glue for the high-temperature resistant wire rope core conveyer belt prepared according to the method has excellent heat and oxidization resistance, weather resistance, ozone resistance, acid-base resistance and steam resistance, and can be used for a long term under the use conditions that the temperature is not higher than 175 DEG C and the highest short-time running temperature is at 300 DEG C.

Description

technical field [0001] The invention relates to a surface covering glue for a high-heat-resistant steel cord conveyor belt. The covering glue can withstand a test temperature of no more than 175°C, and the highest short-term operating temperature is 300°C, and meets the T4 level of the GB / T 20021-2005 standard. Background technique [0002] Wire rope conveyor belts generally have long conveying distance, large conveying capacity, good conveyor stability and long service life, and are suitable for long intervals, large distances, and high-speed conveying materials. However, the general steel cord conveyor belt is mainly made of styrene-butadiene rubber and natural rubber. Due to the limitation of the material itself, in the hot oxygen environment exceeding 100 ℃, the rubber is prone to aging, losing elasticity and cracking, and the bending during transportation. The cover rubber is easy to wear or even fall off under flexure, which affects the service life. Therefore, in cem...
