Description
Technical Field
The invention relates to the technical field of mining conveying belts, in particular to an energy-saving wear-resistant steel wire rope core conveying belt and a manufacturing method thereof.
Background
The steel wire rope core conveyer belt is a main tool for conveying materials in the industries of coal mine, metallurgy, mine, harbor, electric power, building materials and the like. The steel wire rope core conveyer belt comprises steel wire core, middle glue film and upper and lower cover glue film: the steel wire rope and the middle adhesive layer are bonded to form a strong layer, so that the bearing capacity of the conveying belt is determined, and the conveying belt is required to have high strength and good bonding performance; the rubber layer is covered to convey materials, so that the service life of the conveying belt is determined, and the conveying belt is required to have good wear resistance and strong impact resistance; the lower covering layer transmits power to determine energy consumption, and requires low rolling resistance and energy conservation. The service life of the steel wire rope core conveying belt in the prior art in China is about 5 years generally, the foreign advanced level can reach 8-10 years, and mainly because the wear resistance of the prior art in China is poor, the improvement of the wear resistance of the steel wire rope core conveying belt is an effective way for improving the service life of the steel wire rope core conveying belt. Researches show that the indentation rolling resistance of the steel wire rope core conveying belt accounts for more than 60% of the main resistance of the conveyor, so that the reduction of the indentation rolling resistance of the steel wire rope core conveying belt has important significance for reducing the energy consumption of the conveyor, reducing the running cost and improving the economic benefit. The indentation rolling resistance of the steel wire rope core conveyer belt is caused by the viscoelastic property of the running surface of the conveyer belt and mainly caused by the dynamic viscoelastic property of the lower covering layer. The loss factor (tan delta value at 60 ℃) is an important parameter for representing the dynamic viscoelasticity of the material, and the reduction of tan delta can reduce the hysteresis loss of the running surface of the conveyer belt, correspondingly reduce the power consumption of the conveyer belt and achieve the purpose of energy conservation. Therefore, the tan delta value of the lower covering layer of the steel wire rope core conveying belt is reduced by optimizing the formula and the process, and the method is an effective way for reducing the rolling resistance of the steel wire rope core conveying belt.
