Problems solved by technology

However, the blending performance of the vulcanizing agent, vulcanization activator and accelerator with the rubber matrix is ​​poor, and the interaction between the components is not strong
After adding a vulcanizing agent into the rubber matrix, due to the small interaction force between the vulcanizing agent and the rubber matrix, the vulcanizing effect of the vulcanizing agent on the rubber matrix is ​​not ideal, and the improvement of the performance of the V-belt is poor, which needs to be improved

Abstract

The invention discloses a triangle belt with high tensile strength and high weather resistance and a preparation method thereof. The triangle belt comprises a strength layer, a buffer rubber layer, acompressed rubber layer and a coating cloth layer. Raw materials of the compressed rubber layer comprise the following components of chloroprene rubber, cis-polybutadiene rubber, zinc oxide, filler, aromatic oil, a vulcanizing agent and rosin-based sodium sulfosuccinate diester. The rosin-based sodium sulfosuccinate diester has dispersion and emulsification effects and can improve the compatibility and mixing uniformity of the vulcanizing agent, the chloroprene rubber and the cis-polybutadiene rubber , the vulcanizing effect of the vulcanizing agent is improved, and the weather resistance andthe tensile strength of the compressed rubber layer are improved. The zinc oxide has the property of a reinforcing agent and enables the compressed rubber layer to have good tear resistance and elasticity. The zinc oxide has the property of a vulkacit and enhances the vulcanization activity of the compressed rubber layer. The emulsification effect of the rosin-based sodium sulfosuccinate diester can improve the acting force between the zinc oxide, the chloroprene rubber and the cis-polybutadiene rubber and improve the performance enhancement effect of the zinc oxide as the reinforcing agent and the vulkacit on the compressed rubber layer.

Description

technical field [0001] The invention relates to the technical field of transmission belts, in particular to a V-belt with high tensile strength and high weather resistance and a preparation method thereof. Background technique [0002] The V-belt belongs to a kind of transmission belt, including a compression rubber layer, a strength layer, a buffer rubber layer and a cloth covering layer. Among them, the strength layer is the skeleton of the V-belt. The main types are polyester cord, polyester tempered brown silk, aramid cord and dipped cord fabric, etc., and its function is to bear the tension generated by the V-belt during operation. Equal stress is the main force-bearing part in the V-belt transmission process. The buffer rubber layer plays the role of fixing the strength layer and can absorb the dynamic shear stress generated by the frequent deformation of the V-belt during high-speed operation. The compression rubber layer is composed of rubber with excellent bending...
