Abstract

The invention discloses a nano conveyor belt which consists of tyre fabrics or canvas and a high polymer composite material covered on the fabrics or the canvas, wherein the high polymer composite material comprises the following raw materials in parts by weight: 20-40 parts of chloroprene rubber, 5-10 parts of nitrile rubber, 5-10 parts of natural rubber, 5-15 parts of polyvinyl chloride, 10-20 parts of diocty phthalate, 2-5 parts of chlorinated paraffin, 2-5 parts of antimonous oxide, 2-5 parts of tritolyl phosphate, 0.1-0.3 part of tetraisopropyl titanate, 0.1-0.5 parts of hydroquinone dibenzyl ether, 0.1-0.5 parts of tetramethylthiuram disulfide, 0.3-0.6 part of sulphur, 2-5 parts of carbon black and 1-3.6 parts of nano particles. The nano conveyor belt prepared of the invention is characterized in that the surface resistivity is 1.5*105 omega, and the body resistivity is 3.0*1.3 omega.m; the combustion time is 1.3 second, and the smoldering time is 0 second; and after the nano conveyor belt is soaked in water for 70 hours, the antistatic performance and flame resistance thereof have no obvious change.

Description

Technical field [0001] The invention relates to a conveyor belt for coal mines, in particular to a nano safety conveyor belt for coal mines and a preparation method thereof. Background technique [0002] Rubber and plastic are high resistivity materials that are easy to burn and accumulate static electricity. The surface resistivity of the material is as high as 10 13 Ω. This material is easy to accumulate a large amount of static electricity when rubbing against other objects or contacting and separating. In the coal mine environment with gas, especially in the dry coal mining area, the material will generate electrostatic spark discharge due to contact separation or friction at any time. To detonate the gas, many antistatic conveyor belts produced by some companies actually exceed the static index. For example, "General Guidelines for the Prevention of Static Electricity" national standard GB12158-20067.2.1 points out that under normal circumstances, the surface resistivity an...
