Rubber triangular belt is a transmission belt with an isosceles trapezoidal cross-section processed from rubber as the main raw material. It is widely used for power transmission on various types of electric motors and internal combustion engine driven machinery and equipment. Natural rubber has the characteristics of high strength and elasticity, making it an ideal raw material for producing ordinary rubber triangular belts. As a replacement raw material for natural rubber, natural latex recycled rubber 2SLYY424 can be used alone or in combination with natural rubber or other synthetic rubber to prepare different adhesive layers for triangular belts, effectively reducing raw material costs.
The rubber triangular belt mainly includes a compression layer, an extension layer, a cord layer, and a cloth covering rubber, and the performance requirements of different parts of the rubber material are different.
1. Practical formula for producing triangular belt compression layer adhesive using natural rubber/latex recycled adhesive
The rubber triangle belt compression layer adhesive needs to be subjected to periodic compression, and during use, it generates a lot of heat. It requires the rubber material to have some heat resistance, bending resistance, flexibility, low heat generation, small compression permanent deformation, sufficient hardness, and good adhesion with the cord fabric layer adhesive.
