Problems solved by technology

[0005] In view of the problem in the prior art that the wear resistance of the conveyor belt is greatly reduced when it is affected by a large temperature change in the external environment due to the poor temperature resistance of the conveyor belt, the first purpose of the present invention is to provide a temperature-resistant Modified conveyor belt to solve the above technical problems. When it is affected by a large temperature change in the external environment, its own wear resistance will not be greatly reduced, and it can still maintain good structural stability, and the overall has good temperature resistance. Transformative

Abstract

The invention discloses a temperature-change-resistant conveying belt and a preparation method thereof, and relates to the technical field of conveying belts. The problem that the wear resistance of the conveying belt is greatly reduced when the conveying belt is influenced by large temperature change of an external environment due to poor temperature change resistance of the conveying belt is solved. The temperature-change-resistant conveying belt comprises the following components in parts by weight: 60-70 parts of polyurethane rubber; 20-25 parts of butadiene-acrylonitrile rubber; 3 to 5 parts of carbon nanotubes; 5 to 15 parts of dioctyl phthalate; 10-18 parts of a wear-resistant filler; 2-4 parts of a stabilizer; 3-5 parts of a flame retardant; 8 to 12 parts of polyborosiloxane; 3 to8 parts of dicumyl peroxide; 9-15 parts of a PU adhesive; and 20-30 parts of a skeleton fabric. When the temperature-change-resistant conveying belt is affected by large temperature change of the external environment, the abrasion resistance of the temperature-change-resistant conveying belt is not greatly reduced, good structural stability can still be kept, and the whole temperature-change-resistant conveying belt has good temperature change resistance.

Description

technical field [0001] The invention relates to the technical field of conveyor belts, more specifically, it relates to a temperature-resistant deformed conveyor belt and a preparation method thereof. Background technique [0002] Conveyor belt, also known as conveyor belt, is a composite product of rubber, fiber and metal, or a composite product of plastic and fabric, which is used in the belt conveyor belt to carry and transport materials. At the same time, conveyor belts are widely used in cement, coking, metallurgy, chemical, steel and other industries where the conveying distance is short and the conveying volume is small. [0003] In the Chinese invention patent application document with the publication number CN109776895A, a wear-resistant and flame-retardant conveyor belt and its preparation process are disclosed. Rubber and lower covering rubber, the skeleton material is steel wire rope or flame-retardant polyester fabric; the covering rubber includes the following...
