Abstract

The invention relates to the field of rubber materials, and discloses a nitrile rubber / lignin composition, a nitrile rubber / lignin composite material and a preparation method and application thereof.The composition contains a nitrile rubber matrix, lignin, an interface reactant and a vulcanizing aid which are stored in a mixed manner or independently stored, and an activating aid is optically selected; with respect to the 100 parts of nitrile rubber matrix by weight, the contents of 1-150 parts of lignin, 0.05-30 parts of interface reactant, 0-50 parts of activating aid and 0.1-30 parts of vulcanizing aid are arranged. The nitrile rubber / lignin composite material with different mechanical properties can be obtained, the tensile strength of the nitrile rubber / lignin composite material canreach 10-30 MPa, and the elongation at break of the nitrile rubber / lignin composite material can reach 250-800%.

Description

technical field

[0001] The invention relates to the field of rubber materials, in particular to a nitrile rubber / lignin composition, a method for preparing a nitrile rubber / lignin composite material and a nitrile rubber / lignin composite material prepared by the method , and the application of the nitrile rubber / lignin composite material in at least one of automobile hoses, printer rollers and foamed heat insulating materials. Background technique

[0002] Nitrile-butadiene rubber (NBR) is a synthetic rubber prepared by copolymerization of butadiene and acrylonitrile emulsion. With its good oil resistance, hydrocarbon solvent resistance and heat aging resistance, it is widely used in automobiles, aerospace, petroleum Chemical, textile, wire and cable, printing and food packaging and other fields. Its disadvantages are poor low temperature resistance, ozone resistance and poor UV aging resistance.

[0003] Lignin is the most abundant renewable aromatic polymer in nature, mai...
