Problems solved by technology

However, Teflon coating is not easy to bond. The timing belt with Teflon coating on the surface needs to be equipped with special Teflon coating spraying equipment. The production process is complicated, and the tensile strength and impact strength of wear-resistant polyurethane are excellent. Teflon coating

Abstract

The invention relates to an anti-wear synchronous belt which comprises a polyurethane base layer, wherein a core rope framework is arranged in the polyurethane base layer; a wear-resistant polyurethane layer is arranged on the surface of the polyurethane base layer; the wear-resistant polyurethane layer is an organosilicone modified polyurethane elastomer; the thickness of the wear-resistant polyurethane layer is 1-10mm. The preparation method of the anti-wear synchronous belt comprises the following steps: preparing and integrally molding the polyurethane and the core rope framework by virtueof extrusion molding so as to obtain the polyurethane base layer; adhering the wear-resistant polyurethane layer to the surface of the polyurethane base layer by virtue of a hot melt adhesion process. Compared with the prior art, the anti-wear synchronous belt disclosed by the invention has the advantages of being light in weight, excellent in impact resistance, wear-resistant, cut-resistant andthe like, and can be widely applied to the driving conveying industry.

Description

technical field [0001] The invention relates to the technical field of conveyor belt manufacture, in particular to an anti-wear synchronous belt. Background technique [0002] At present, synchronous belts are widely used in the fields of transmission, transportation, and industrial transportation, but logistics conveyor belts are not wear-resistant and puncture-resistant, and the service life of synchronous belts is greatly reduced. Especially in the field of steel plate transportation, the burrs of the steel plate are very easy to puncture and wear the surface of the synchronous belt. The surface of the synchronous belt is scratched and punctured frequently. The factory has to increase the replacement frequency of the synchronous belt. This phenomenon greatly reduces the production efficiency of the factory and does not meet the needs of modern industrial development. [0003] Chinese patent CN 207107621U discloses a polyurethane synchronous belt for transmission, includi...
