High-load narrow V-belt and preparation method thereof

Abstract

The invention relates to the technical field of V-belts, in particular to a high-load narrow V-belt and a preparation method thereof. The V belt comprises a fiber adhesion layer and a montmorillonitemodified inner layer, wherein the montmorillonite modified inner layer is prepared from the following raw materials: nitrile rubber, chlorinated nitrile rubber, butadiene styrene rubber, ethylene propylene diene monomer, bismaleimide resin, polyaryletherketone, polyarylethersulfone, nano calcium silicate, nano barium silicate, nano calcium oxalate and modified montmorillonite; and the fiber adhesion layer is prepared from the following raw materials: chlorosulfonated polyethylene rubber, fluororubber, butadiene rubber, graphite fibers, silicon carbide fibers and poly (p-phenylene benzobisoxazole) fibers. The V belt is good in compatibility between raw material molecules, large in loading capacity and high in strength.

Description

technical field [0001] The invention relates to the technical field of V-belts, in particular to a high-load narrow V-belt and a preparation method thereof. Background technique [0002] Rubber V-belts are important spare parts in modern industrial production equipment. Rubber V-belts are wrapped V-belts and trimmed V-belts, and V-belts are friction transmission. V-belts are also used in a wide range of fields, such as automotive V-belts, motorcycle variable-speed V-belts, agricultural machinery variable-speed V-belts, etc. It is also used in a variety of working conditions, including high loads. In high load environments, the belt is driven by friction and the temperature rises very high. Then in the high cold area, such as below minus 40 ℃, some rubber will become brittle. For example, the patent number is CN201910832600.7, a high and low temperature resistant EPDM V-belt, which uses EPDM rubber, accelerator, zinc oxide, anti-aging agent, carbon black, paraffin oil, pero...

AI Technical Summary

Problems solved by technology

For example, the patent number is CN201910832600.7, a high and low temperature resistant EPDM V-belt, which uses EPDM rubber, accelerator, zinc oxide, anti-aging agent, carbon black, paraffin oil, peroxide crosslinking agent, cotton Powder and nylon enable the V-belt to cope with a variety of temperature differences, but in order to take into account the temperature difference in its production, the strength of the V-belt is reduced

Another example is a rubber V-belt vulcanized rubber sleeve with the patent number CN201910501668.7 and its production method, using ExxproTM special elastomer, plasticizer, magnesium oxide, zinc oxide, tackifying resin, microcrystalline wax, surface lubricant, Reinforcing agent, vulcanized resin, and accelerators make the rubber sleeves have excellent air tightness and heat-oxidative aging resistance, but the raw materials are not deeply bonded, and the strength and load capacity are not high enough, so a special rubber sleeve is made for Highly loaded V-belts are extremely necessary
