Problems solved by technology

At present, there are many flame-retardant conveyor belts in China, all of which are composed of a skeleton material layer and a covering rubber layer. The rubber mill is thin and worn, so that the skeleton material layer is damaged, and the service life is short. The conveyor belt needs to be replaced frequently and disassembled frequently, causing certain troubles

Embodiment 1

[0016]

[0017] The preparation method is as follows: the raw materials are placed in a mixer and stirred evenly, then the above mixture is put into a rubber mixer to be rubberized into a sheet, and the sheet-shaped high polymer composite material is covered on the flame retardant cord fabric or canvas. , vulcanized and formed in a vulcanizing machine, and finally checked for winding.

[0018] The present invention can be used for material conveying at 150°C, and has the properties that ordinary heat-resistant belts do not have flame retardant properties, and can prevent large-area burning of the entire conveyor belt.

Embodiment 2

[0020]

[0021] The preparation method is the same as above.

[0022] The invention adds a high-efficiency composite flame retardant, so that the wear resistance of the flame-retardant conveyor belt is greatly improved, the service life of the flame-retardant conveyor belt is prolonged, and the production and maintenance cost is reduced.

Embodiment 3

[0024]

[0025] The preparation method is the same as above.

[0026] The product of the invention has good physical properties, low electrostatic conductivity and excellent flame retardant properties, and the invention is suitable for material transportation in various industries.

[0027] This product adds a high-efficiency composite flame retardant, which greatly improves the wear resistance of the flame-retardant conveyor belt, prolongs the service life of the flame-retardant conveyor belt, and reduces production and maintenance costs; the invention can be used for material transportation at 150 ° C, and has Ordinary heat-resistant belts do not have flame retardant properties, which can prevent large-scale burning of the entire conveyor belt. The product of the invention has good physical properties, low electrostatic conductivity and excellent flame retardant properties, and the invention is suitable for material transportation in various industries.

Abstract

The invention discloses a fire-retardant conveyer belt for the industrial and mineral industry. The fire-retardant conveyer belt for the industrial and mineral industry is composed of the chloroprene rubber (CR), ethylene-propylene-diene monomer rubber, chlorinated paraffin and antimonous oxide. The preparation method comprises the following steps: putting the raw materials in a stirrer, stirring uniformly, then putting the mixture into a rubber mixing machine, milling into sheets, covering a fire-retardant shade cloth or canvas with the sheet polymer composite material, performing vulcanization molding in a vulcanizing machine, and coiling and detecting. The fire-retardant conveyer belt is excellent in physical performance, low in electrostatic conductive performance, good in fire resistance and suitable for conveying each material of the industrial and mineral industry.

Description

technical field [0001] The invention relates to a conveyor belt, belonging to the technical field of conveyor belts, in particular to a fire-resistant conveyor belt for industrial and mining industries Background technique [0002] Conveyor belts are widely used in mining, metallurgy and chemical industries. However, fields such as coal mines have special requirements for conveyor belts, requiring them to have better flame retardant properties and no harm to the human body. This has led to the fact that the general conveyor belt produced can no longer meet its special requirements. [0003] Generally, ordinary heat-resistant conveyor belts are usually used to transport materials that do not exceed 150 °C. In recent years, some companies have reported that due to conveyors and industrial and mining conditions, the heat-resistant conveyor belts used may instantly reach a flammable temperature of rubber organic materials, causing the conveyor belt to burn. As a result, the e...
