Special composite wear-resistant rubber for inorganic enhanced driving belt and preparation method

Abstract

The invention relates to the technical field of functional rubber and preparation thereof, in particular to special composite wear-resistant rubber for an inorganic enhanced driving belt and a preparation method. The special composite wear-resistant rubber comprises butadiene styrene rubber, butadiene rubber, ethylene propylene diene monomer, wear-resistant fillers, sulfur, coupling agents, filling reinforcing agents, anti-aging agents, softening agents and vulcanizing agents, wherein the wear-resistant fillers are layered silicate wear-resistant fillers of molybdenum disulfide coated graphene. The method includes the steps: spraying precursor liquid prepared from molybdenum chloride and nickel chloride to the surface of graphene loaded layered silicate, drying the layered silicate, sintering the layered silicate in a calcining furnace with sulfur-containing nitrogen atmosphere and cooling the layered silicate to obtain the wear-resistant fillers; performing mixing, heat treatment andmilling on rubber raw materials to obtain the special composite wear-resistant rubber. The special composite wear-resistant rubber for the inorganic enhanced driving belt has the advantages of good wear resistance and obvious tensile strength improvement effects, the added graphene does not easily fall off and is high in stability, and the service time of the special composite wear-resistant rubber for the inorganic enhanced driving belt is prolonged.

Description

technical field [0001] The invention relates to the technical field of functional rubber and its preparation, in particular to an inorganic reinforced transmission belt special composite wear-resistant rubber and a preparation method. Background technique [0002] The drive belt, also known as the conveyor belt, is the transmission medium in the drive belt system. The transmission belt system is a kind of transmission system. The system will include two or more pulleys with a transmission belt on it. The pulleys can rotate the transmission belt without limit. One or more of the pulleys are powered to travel the belt and carry the material being driven on the belt. The powered pulley will be called the drive pulley and the rest will be called the idler pulley. There are two occasions for industrial application of conveyor belts: in factories, material handling in which conveyed materials or objects are placed in boxes or trays, and transport of large quantities of materials...
