Problems solved by technology

Cloth-wrapped V-belts are relatively large and economical transmission belts at present. However, in the actual production process, it is found that since the main purpose of V-belts is for power transmission between equipment transmission belts and pulleys, the scene of V-belts in use is complicated. There are many interference factors, resulting in serious performance attenuation of the V-belt, and the maintenance is cumbersome. In order to improve the efficiency of use, it takes a lot of manpower to clean the V-belt to ensure its use effect
[0003] In the current technology, there are many studies on V-belts, such as a dry cloth V-belt and its preparation method with the patent No. CN201910777471.6, including a wrapping layer and an inner core belt, through the top rubber layer, the skeleton layer and the bottom rubber layer. The setting of the V-belt makes the V-belt adapt to more application scenarios, but ignores the use and maintenance of the V-belt; another example is a modified neoprene V-belt and its preparation method with the patent No. CN200910100533.6, using neoprene , Acid-modified carbon nanotubes, carbon black, phosphorus oxides, sulfur, anti-aging agents, fillers, softeners, plasticizers, and accelerators make the modified neoprene V-belts have good heat resistance, oil corrosion resistance, Antistatic and flame retardant properties, likewise, lack of in-depth research on self-cleaning of V-belts

Abstract

The invention relates to the field of V belts, in particular to a preparation method of a self-cleaning transmission V belt, which specifically comprises the following steps: mixing polyurethane rubber with acetone, adding nano acicular wollastonite powder, nano montmorillonite powder, sodium dioctylsulfosuccinate, dicumyl oxide, fluororubber 26 and chromium oxide ceramic fiber, performing dryingto obtain sediments, and pulverizing the sediments into superfine powder; mixing with butadiene rubber, epichlorohydrin rubber, acrylate rubber and ethylene-propylene rubber, and spraying a film. A large number of active bacteriostatic ions and hydrophobic layers are formed on the surface of the V-belt, flying dust in air is effectively prevented from adhering to the surface of the V-belt under the action of microorganisms, manual cleaning in production is reduced, good structural performance of the V-belt is guaranteed, and use scenes of the V-belt are effectively expanded.

Description

technical field [0001] The invention relates to the technical field of V-belts, in particular to a preparation method of a self-cleaning transmission V-belt. Background technique [0002] A V-belt is a unique type of conveyor belt, a mechanical device used to transmit force and transport items. It has the advantages of easy installation, small footprint, high transmission efficiency and low noise. Cloth-wrapped V-belts are relatively large and economical transmission belts at present. However, in the actual production process, it is found that since the main purpose of V-belts is for power transmission between equipment transmission belts and pulleys, the scene of V-belts in use is complicated. There are many interference factors, resulting in serious performance attenuation of the V-belt, and the maintenance is cumbersome. In order to improve the use efficiency, it takes a lot of manpower to clean the V-belt to ensure its use effect. [0003] In the current technology, th...
