Modified hydrogenated nitrile-butadiene rubber and its preparing method

Abstract

The present invention relates to the preparing technology of composite rubber material. Carbon nanotube via surface treatment and liquid rubber are ultrasonically mixed and added into partial hydrogenated nitrile-butadiene rubber to prepare mother rubber; the mother rubber is mixed with the rest hydrogenated nitrile-butadiene rubber, carbon black, zinc oxide and sulfurizing agent, and the mixture is mixed in a rolling mixer or a Banbury mixer and sulfurized to obtain the carbon nanotube modified hydrogenated nitrile-butadiene rubber. The present invention has the beneficial effects of raised heat performance, antiwear performance, mechanical strength, antiageing performance, etc. raised use performance and expanded application range.

Description

technical field

[0001] The invention relates to a carbon nanotube modified hydrogenated nitrile rubber and a preparation method thereof, belonging to the technical field of preparation of rubber polymer composite materials. Background technique

[0002] Hydrogenated nitrile rubber has many balanced and excellent properties such as heat resistance, oil resistance, wear resistance and high mechanical strength, so it is widely used in many industries such as automobiles, machinery, and oil drills. However, with the development of science and technology and the improvement of equipment performance, the requirements for heat resistance and wear resistance of rubber seals as functional accessories are getting higher and higher. The existing rubber parts made of hydrogenated nitrile rubber have been difficult to meet the wear resistance and heat resistance requirements of some occasions. Contents of the invention
