High-performance, low-pollution and recovering metal ligand cross-linked nitrile rubber materials

Abstract

High performance, low pollution and regenerated metal coordinative cross linked acrylonitrile-butadiene rubber comprises acrylic nitrile 18 - 50wt%, acrylonitrile-butadiene rubber with Mooney viscosity of 20 - 100, liquid butyronitrile, carboxylic butyronitrile, hydrogenated butyronitrile, powdery butylonitrile, a butyronitrile contained mixture or / and nitrile containing copolymer or grafts and halides of transition metals or / and oxygen containing salts, and is obtained by cross reacting at 200deg.C for 5 - 60minutes. Its advantages include no harmful materials used in production, good mechanical performance without carbon black added, oil-resistant, good adhesion with metals and regenerating ability.

Description

technical field

[0001] The invention relates to a nitrile rubber material, in particular to a nitrile rubber material formed by coordination and crosslinking of metal ions and nitrile groups in nitrile rubber. Background technique

[0002] When rubber is used as a material, the linear polymer is cross-linked into a three-dimensional network polymer by means of covalent bond cross-linking such as vulcanization, and a large amount of inorganic substances such as carbon black and various organic additives are added at the same time. Cross-linked rubber is a non-melting, insoluble substance that is difficult to recycle. In addition, the heterocyclic compounds of vulcanization accelerators necessary for cross-linking are mostly carcinogens, which seriously affect people's health; and carbon black, which is used as a rubber reinforcement material, is easily scattered during use and pollutes the environment. Therefore, making rubber a renewable and environmentally friendly high-pe...
