Abstract

The invention belongs to the field of rubber for transmission belts and in particular relates to a rubber composition for V belt wrapper glue, the V belt wrapper glue and a preparation method of the V belt wrapper glue. The V belt wrapper glue is prepared from the following components in parts by weight: 5-30 parts of acrylate rubber, 40 parts of ethylene propylene diene monomer, 0.5-2 parts of sulfur, 1.5-2.5 parts of an accelerator, 3-6 parts of magnesium oxide, 1-3 parts of zinc oxide, 50-70 parts of a reinforcing agent, 10-20 parts of a softener, 2-5 parts of tackifying resin and 1-3 parts of an antioxidant. The V belt wrapper glue has he characteristics of good oil resistance, high thermal oxidative aging resistance and good processability.

Description

technical field [0001] The invention belongs to the technical field of rubber for transmission belts, and in particular relates to a rubber composition, a V-belt wrapping glue using the rubber composition and a preparation method. Background technique [0002] V-belt tape, referred to as V-belt or V-belt, is an endless transmission belt with a trapezoidal cross section. Like the flat drive belt, the V-belt is also the power generated by the rotation of the motor of the prime mover, which is transmitted to the mechanical equipment by the belt through the pulley. V-belt is the product with the largest output and the widest application in the transmission belt. V-belts are widely used in ships, electric power, coal, office and other fields. [0003] The current V-belt products on the market are mainly rubber transmission belts. In some special industrial fields, such as chemical, automobile and coal industries, V-belts need to work in high temperature, lubricating oil contai...
