Abstract

The invention discloses a non-phthalate nitrile rubber material and a preparation method thereof, and belongs to the technical field of nitrile rubber materials and preparation methods thereof. The non-phthalate nitrile rubber material comprises the following components in percentage by weight: 35%-40% of nitrile rubber, 15%-20% of fast extruding furnace carbon black, 10%-15% of semi-reinforcing furnace carbon black, 15%-20% of light calcium carbonate, 3.0%-5.0% of zinc oxide, 0.5%-1.0% of stearic acid, 0.6%-1.0% of 4,4'-di(phenyl isopropyl)diphenylamine, 0.2%-0.5% of sulfur, 0.2%-0.5% of an accelerant TT, 0.6%-1.0% of an accelerant TET, 0.6-1.0% of an accelerant CZ, and 5.0%-10.0% of a plasticizer D-810. The preparation method comprises the following steps: mixing masterbatches; performing two-stage sulphuration on the masterbatches. The non-phthalate nitrile rubber material meets the requirements of an REACH (Registration, Evaluation and Authorization of Chemicals) rule, the performance of the material is superior to that of an existing phthalate nitrile rubber material, the price of the material is the same as that of the existing phthalate nitrile rubber material, and the cost of the material does not need to be increased.

Description

technical field [0001] The invention belongs to the technical field of acrylonitrile-butadiene rubber materials and preparation methods thereof, and more specifically relates to a non-phthalate acrylonitrile-butadiene rubber material and a preparation method thereof. Background technique [0002] With the rapid development of the global automobile industry, more and more world-renowned automobile manufacturers have set their sights on China, which provides a good opportunity for our rubber companies to enter the global rubber auto parts supplier, but at the same time we also Facing the severe test, enterprises exporting products to Europe must comply with EU REACH regulations, and must make declarations in accordance with the candidate list of 84 substances of high concern and undertake corresponding obligations. [0003] REACH is the abbreviation of Regulation Concerning the Registration, Evaluation, Authorization and Restriction of Chemicals (English: Regulation Concerning...
