Temperature-deformation-resistant conveying belt and preparation method thereof

Abstract

The invention relates to the field of conveying belts, and particularly discloses a temperature-deformation-resistant conveying belt and a preparation method thereof. The temperature-deformation-resistant conveyor belt is prepared from the following raw materials in parts by weight: 60 to 100 parts of acrylate rubber, 120 to 200 parts of silicone rubber, 30 to 50 parts of carbon black, 20 to 40 parts of skeleton woven fabric, 5 to 15 parts of epoxy resin, 15 to 20 parts of dicumyl peroxide, 10 to 15 parts of carbon fiber, 5 to 20 parts of calcium carbonate, 5 to 10 parts of titanium dioxide, 5 to 16 parts of m-phenylenediamine, 5 to 10 parts of iron sulfide, 5 to 10 parts of stearic acid, 5 to 8 parts of anti-aging agent and 6 to 15 parts of argil. The preparation method comprises the following steps: drying the skeleton woven fabric for later use, preparing the adhesive layer, preparing the rubber layer, and carrying out hot-pressing lamination on the adhesive layer and the rubber layer. The conveyor belt prepared by the invention has high temperature resistance and wear resistance.

Description

technical field

[0001] The application relates to the field of conveyor belts, more specifically, it relates to a temperature-resistant deformed conveyor belt and a preparation method thereof. Background technique

[0002] Conveyor belts are widely used in agriculture, industrial and mining enterprises, and transportation industries to transport various solid block and powder materials or finished items. Occasions where the length is short and the conveying volume is small. The conveyor belt can be transported in a continuous, high-efficiency, and large-inclination angle. The conveyor belt is safe to operate, easy to use, easy to maintain, and low in freight. It can also shorten the transportation distance, reduce the engineering cost, and save manpower and material resources.

[0003] In 2005, the country formulated the recommended standard GB / T20021-2005 for canvas core heat-resistant conveyor belts, which stipulated four heat-resistant grades (T1 / 100°C, T2 / 125°C, T3 / 150°...
