Abstract

The invention belongs to the technical field of graphene rubber composite materials, and proposes a graphene modified nitrile rubber and a preparation method thereof. A graphene-modified nitrile rubber, comprising the following components by weight: 70-90 parts of nitrile rubber, 10-30 parts of modified graphene oxide carboxylated nitrile-butadiene rubber masterbatch, 1.5-2 parts of vulcanizing agent, 0.5-2.0 parts of vulcanization accelerator, 3-5 parts of vulcanization activator, 1-3 parts of plasticizer, 1-2 parts of anti-aging agent, 20-30 parts of filler, modified graphene oxide-carboxylated nitrile rubber masterbatch includes The modified graphene oxide also includes carboxylated nitrile latex, wherein the modified graphene oxide is obtained by dehydrating and condensing graphene oxide after hydrolysis of mercaptosiloxane. Through the above technical scheme, the problem of poor high and low temperature resistance of nitrile rubber in the prior art is solved.

Description

technical field

[0001] The invention belongs to the technical field of graphene rubber composite materials, and relates to a graphene modified nitrile rubber and a preparation method thereof. Background technique

[0002] Nitrile rubber is a copolymer obtained by emulsion polymerization of butadiene and acrylonitrile. Due to the introduction of highly polar cyano groups into the molecular chain, it is known for its excellent oil resistance. As a kind of oil-resistant rubber, nitrile rubber is widely used in the manufacture of oil-resistant products such as hoses, capsules, sealing products, and gaskets. As a seal, vulcanized nitrile rubber will face various harsh application environments, so it is necessary for nitrile rubber to have good adaptability to various environments. Nitrile rubber is non-crystalline rubber, but due to the presence of polar cyano groups, it has poor cold resistance, which leads to a sharp slowdown of the relaxation process at low temperatures, incr...
