Abstract

The present application discloses self-assembled nanocomposite coatings for surface modification of rubber profiles. It consists of (dendritic macromolecule / graphene oxide) n alternating interface layers deposited alternately on the surface of a rubber profile by dendritic macromolecule interfacial layers and graphene oxide interfacial layers. The surface modification of the rubber profile through the self-assembled nanocomposite coating of the present application can improve the strength and wear resistance, and prolong the service life. Correspondingly, the present application also provides a long-life rubber conveyor belt. The surface of the upper covering rubber layer of the long-life rubber conveyor belt is modified by a self-assembled nanocomposite coating, so that the service life is longer.

Description

technical field [0001] The application relates to the field of modified rubber materials, specifically self-assembled nanocomposite coatings for surface modification of rubber profiles, and their application on rubber conveyor belts. Background technique [0002] The "13th Five-Year Plan" guideline for the development of the new material industry requires focusing on the development of new products of high-performance rubber materials to improve their service life and quality stability under extreme conditions. The rubber conveyor belt is composed of a middle core layer and a cover rubber layer covering both sides, and has been widely used in material transportation in mining, building materials, metallurgy and other industries. At present, the cover rubber sheet layer on the rubber conveyor belt is generally prepared from the raw material rubber with stearic acid, turpentine oil, anti-aging agent, zinc oxide, and reinforcing carbon black through mastication, mixing, sheetin...
