Ordinary rubber V-belt is a kind of rubber products for mechanical transmission with trapezoidal cross-section and V-shaped on both sides, which is generally composed of compression layer, extension layer, cord layer and wrapping layer, and the performance requirements of different rubber layers are different. In actual production, natural rubber has good elasticity, wear resistance and anti-aging properties, and is widely used in the preparation of rubber compounds for each rubber layer of the V-belt.

Ordinary rubber V-belt compression layer rubber requires the rubber compound to have good heat resistance, flexural resistance, small heat generation, small compression deformation, good adhesive performance and sufficient hardness; The extension layer rubber requires the rubber compound to have good fatigue E4LYY828 resistance, large elasticity, small deformation and high tensile stress; The coating layer glue requires the rubber material to have certain adhesion and wear resistance, heat resistance, aging resistance, flexural resistance and other properties, and has good adhesion performance with the cloth layer. When using reclaimed rubber to reduce the production cost of natural rubber V-belt, we must choose the appropriate reclaimed rubber according to the specific needs of each rubber layer, and reasonably design the formula of each component of the rubber V-belt containing reclaimed rubber.
