Abstract

The invention provides a mildewproof cold-resistant nitrile rubber material and a preparation method thereof. The mildewproof cold-resistant nitrile rubber material comprises the following substances in parts by weight: 65 parts of first nitrile rubber, 35 parts of second nitrile rubber, 5 parts of zinc oxide, 1 part of stearic acid, 203 parts of an anti-aging agent 403, 23 parts of dibutyl sebacate, 120 parts of spray carbon black, 0.4 part of pre-dispersed sulfur, 2 parts of an accelerant TMTD, 2 parts of an accelerant CZ and 2 parts of a mildewproof agent. The nitrile rubber material has mechanical properties, cold resistance, oil resistance and mildew resistance at the same time.

Description

technical field [0001] The invention mainly relates to the technical field of preparation of NBR, in particular to a mildew-proof and cold-resistant nitrile rubber material and a preparation method thereof. Background technique [0002] Nitrile rubber is a copolymer of acrylonitrile and butadiene monomers, mainly produced by low temperature emulsion polymerization. [0003] According to a flexible nitrile rubber material and its preparation method provided by the patent document with the application number of CN201410377659.9, it can be known that the material comprises the following components in parts by weight: nitrile rubber 100, pyrophyllite 15-80, silane Coupling agent 0.5~3, zinc oxide 0.5~5, magnesium oxide 0.5~5, antioxidant 4020RD0.5~1, antioxidant 402040100.5~1, stearic acid 1~2, accelerator DPTT0.5~1, accelerator BZ0.5~1, vulcanizing agent 1~3. The flexible nitrile-butadiene rubber material may also contain one or both of anti-fatigue agents and dioctyl phthala...
