Wear-resistant rubber tube and preparation method thereof

Abstract

The invention discloses a wear-resistant rubber tube and a preparation method thereof, and belongs to the technical field of rubber preparation. Isoprene, limonene and butylene itaconate serve as rawmaterials and are copolymerized and grafted, unsaturated carbon-carbon double bonds are eliminated to form a functional rubber base material, and an isoprene chain gives rubber macromolecules flexibility. Cottonseed oil serves as a raw material, an adsorption film is formed on a rubber master batch friction interface, and friction is reduced, so that a smooth surface is formed on the rubber tube.Graphene oxide and carbon nanotubes are uniformly dispersed and hybridized, titanium acetate is added, nano-type wear reduction fillers are generated by a hydrothermal reduction method, nano-titaniumcan make up sink marks generated by the surface of the rubber tube in the friction process, and the wear resistance of the rubber tube is improved. The wear-resistant rubber tube solves the problem ofpoor wear resistance of a current rubber tube.

Description

technical field

[0001] The invention belongs to the technical field of rubber preparation, and in particular relates to a wear-resistant rubber tube and a preparation method thereof. Background technique

[0002] Rubber Highly elastic polymer material with reversible deformation. It is elastic at room temperature, can produce large deformation under a small external force, and can return to its original shape after the external force is removed. Rubber is a completely amorphous polymer with a low glass transition temperature and often a large molecular weight, greater than hundreds of thousands.

[0003] The rubber industry is one of the important basic industries of the national economy. It not only provides daily and medical light industrial rubber products that are indispensable to people's daily life, but also provides various rubber production equipment or rubber parts for heavy industries such as excavation, transportation, construction, machinery, electronics, and e...

Examples

preparation example Construction

[0034] A method for preparing a wear-resistant rubber tube, comprising the steps of:

[0035] In terms of parts by mass, take 40-60 parts of rubber functional base material, 20-30 parts of EPDM rubber, 10-15 parts of lubricating active agent, 20-30 parts of anti-friction filler, 1-3 parts of anti-aging active agent, 2~5 parts of stearic acid, 3~7 parts of bis(2-ethylhexyl) phthalate, 6~10 parts of rubber masterbatch are mixed, extruded to obtain a matrix, and the matrix is ​​taken and transferred to vulcanization Vulcanize and mold on the machine, vulcanize at a pressure of 8~12MPa, 160~170°C for 5~10min, and then vulcanize once under the same conditions, and the rubber tube is pulled out to obtain a wear-resistant rubber tube.

[0036] Rubber functional base material:

[0037] (1) Take sodium dodecylbenzenesulfonate and add glycerin polyoxyethylene ether polyoxypropylene ether fatty acid ester and deionized water at a mass ratio of 3:1:10, heat up to 50°C and stir for 20 min...
