Abstract

The invention discloses a preparation method of a high-temperature resistant and anti-aging rubber conveyor belt, and belongs to the technical field of chemical rubber new material manufacturing. According to the preparation method of the high-temperature resistant and anti-aging rubber conveyor belt, the antioxygenic performance of the rubber conveyor belt is improved by using tea polyphenol andcamellia in camellia oil, the content of unsaturated fatty acid is up to 80% or above, free radical attack of an oxygen molecule residue initiator in air can be restrained, and thus thermo-oxidative aging resistance of the rubber conveyor belt is improved; and on the other hand, a carbon nanotube has the special pipeline structure and the high specific surface area, and can be used as a carrier oftitanium dioxide to prepare anti-aging modified filling rubber powder, the carbon nanotube, a nano-graphite flake layer and silicon carbide have high heat resistance, the heat dissipation performanceof the rubber conveyor belt can be improved, absorption of ultraviolet light by the titanium dioxide is improved, light aging is reduced, the cross-linking density of the rubber conveyor belt is improved by light energy conversion of the photocatalysis of the titanium dioxide, the cohesion of the rubber conveyor belt is increased, the hardness and the mechanical strength of the rubber conveyor belt are improved, and broad application prospects are achieved.

Description

technical field [0001] The invention discloses a method for preparing a high-temperature-resistant and anti-aging rubber conveyor belt, which belongs to the technical field of manufacturing new chemical rubber materials. Background technique [0002] With the rapid development of social economy, most of the production mode has changed from manual to mechanized, and the conveyor belt has become an indispensable part in mechanized production.
