High-temperature-resistant non-adhesive conveying belt and preparation method thereof

Abstract

The invention discloses a high-temperature-resistant non-adhesive conveying belt and a preparation method thereof, and relates to the technical field of conveying belt processing. The high-temperature-resistant non-adhesive conveying belt comprises a fabric layer, adhesive layers arranged on the two sides of the fabric layer, rubber layers fixed to the adhesive layers and coatings applied to the surfaces of the rubber layers in a coating manner, the fabric layer is made of polyester fibers, the adhesive layers are made of a PU agent, and each rubber layer is prepared from, by weight, 80-100 parts of polyester type TPU, 5-10 parts of silicone oil, 0.1-0.3 part of an antioxidant, 0.1-1 part of a lubricant, 1-3 parts of a compatilizer and 1-5 parts of a filler; and each coating adopts 0.5-1 part of polyurethane acrylate. The conveying belt is prepared by using the above formula, and the surface of the conveying belt is coated with the oleophobic coating, so that the obtained conveying belt has advantages of good high temperature resistance and no material adhesion.

Description

technical field [0001] The invention relates to the technical field of conveyor belt processing, more specifically, it relates to a high-temperature-resistant non-adhesive conveyor belt and a preparation method thereof. Background technique [0002] Conveyor belt is a part of belt conveyor used to carry materials and transmit traction. It is made of specially treated polyester composite fabric as the load-bearing skeleton, coated with PU / PVC resin as the load-bearing surface. As a light conveyor belt, PVC conveyor belt has been widely used in many industries due to its advantages of light weight, long life, good flame retardancy, and less friction. [0003] The Chinese patent with authorized notification number CN101028888B discloses a high temperature resistant conveyor belt, the working surface covering rubber includes: 80-100 parts of binary ethylene propylene rubber; 0-20 parts of EPDM rubber; 4-8 parts of peroxide Dicumyl; 1-3 parts of triallyl isocyanurate; 5-30 part...

AI Technical Summary

Problems solved by technology

[0004] The addition of short aramid fibers in the above patents makes the covering rubber have better wear resistance. However, due to the large difference in structure between aramid fiber and rubber, the compatibility with rubber is poor, which will seriously affect the covering rubber. Adhesion strength between the glue layer and the skeleton layer

When it is used in the baking industry, it is necessary to transport food at a high temperature of 200-250°C. The softening or melting of the surface material of the covering adhesive layer will cause adhesion to the material, and foaming and peeling between the covering adhesive layer and the skeleton are prone to occur. Or the phenomenon of shedding is not conducive to the transportation of materials
