Problems solved by technology

[0004] The addition of aramid short fiber in the above patent makes the covering rubber have excellent 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 layer. Adhesion strength with 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 covering adhesive layer will adhere to the material due to the softening or melting of the surface material, and foaming and peeling between the covering adhesive layer and the skeleton layer are prone to occur. Or the phenomenon of shedding is not conducive to the transportation of materials

Abstract

The invention discloses a high-temperature-resistant in-adhesion PCV conveyer belt and a preparing method thereof, and relates to the technical field of conveyer belt machining. The problem that in the prior art, the conveyer belt cannot achieve high temperature resistance is solved. The high-temperature-resistant in-adhesion PCV conveyer belt comprises a product framework and face glue, and the face glue comprises the following components including, by weight, 58-100 parts of polyvinyl chloride paste resin PB-128, 0.18-30 parts of dioctyl terephthalate, 2.9-5 parts of epoxidized soybean oil,2.9-5 parts of N-hydroxycyclohexyl phenyl ketone-benzothiazole sulfonamide, 3-6 parts of dibutyl phthalate, 1.7-3 parts of color paste, 33-80 parts of polyvinyl chloride paste resin PB-108, 8.2-20 parts of paste resin KP-11, 20.5-50 parts of calcium carbonate and 20-40 parts of modified teflon suspension. The conveyer belt has the high temperature resistance, material adhesion can be avoided evenwhen the conveyer belt is used for conveying foods at the high temperature ranging from 200 DEG C-250 DEG C, and bubbling, peeling or falling can be avoided.

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 PVC 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] A Chinese invention patent with the publication number CN101028888A discloses a high-temperature-resistant conveyor belt, whose working surface covering rubber includes: 80-100 parts of binary ethylene-propylene rubber; 0-20 parts of EPDM rubber; 4-8 parts of over- Dicumyl oxide; 1-3 parts of triallyl isocyanurate; ...
