Abstract
The invention discloses an energy-saving wear-resistant low-smoke halogen-free flame-retardant steel wire rope core conveyer belt and a manufacturing method thereof. Simple process and easy manufacture.
Description
Technical Field
The invention relates to the technical field of mining conveying belts, in particular to an energy-saving wear-resistant low-smoke halogen-free flame-retardant steel wire rope core conveying belt and a manufacturing method thereof.
Background
The steel wire rope core conveying belt is a main tool for conveying coal underground in a coal mine, and according to the regulation of coal mine safety regulations, the steel wire rope core conveying belt used underground must have flame-retardant and antistatic properties, and meets the regulation of MT668-2008 'steel wire rope core flame-retardant conveying belt for coal mine', the standard has higher requirements on the flame-retardant properties of the conveying belt, and the requirements on the mechanical properties of a covering layer are lower. The steel wire rope core flame-retardant conveyor belt produced by the prior art has better flame-retardant and antistatic properties, and has the main problems that the mechanical property of a covering layer is lower, the outstanding performance is that the wear resistance and the impact resistance are poor, and the service life is short; secondly, the main material containing halogen and the flame retardant containing halogen and antimony are used, the ignition amount of the flame retardant belt is large, and the smoke contains halogen, so that secondary disasters such as personnel poisoning, equipment corrosion and environmental pollution are easily caused; and thirdly, the rolling resistance is large and the energy consumption is high in the using process.
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 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. Rubber materials having a tan delta (tan delta value at 60 ℃) of less than or equal to 0.15 are generally defined as low rolling resistance or energy-saving rubber materials. Therefore, the tan delta value of the 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. The prior art researches on how to improve the flame retardant property and the adhesive property of the steel wire rope core flame retardant conveyor belt, and the researches on the energy-saving wear-resistant low-smoke halogen-free flame retardant steel wire rope core conveyor belt are less.
