Abstract

The invention provides acrylic ester rubber and a preparation method thereof. The acrylic ester rubber is characterized by comprising the following components by weight: 70-90 portions of tri-acrylate rubber AR840, 10-30 portions of butyronitrile rubber NBR, 55-75 portions of fast extruding carbon black N550, 1-2 portions of anti-aging agent RD, 1-2 portions of anti-aging agent MB, 0.5-1 portion of anti-scorching agent CTP, 3-5 portions of dioctyl phthalate DOP, 1-2 portions of dispersant rhine powder-42, 0.3-0.5 portion of common sulphur, 0.2-0.4 portion of tetramethyl thiuram disulfide TMTD, 3.5-4.0 portions of sodium stearate and 0.3-0.5 portion of potassium stearate. The sticking phenomenon is reduced and the elasticity, extensile intensity and low temperature resistance of the acrylic ester rubber are improved.

Description

technical field [0001] The invention belongs to the technical field of rubber material production, in particular to an acrylic rubber and a preparation method thereof. Background technique [0002] Acrylate rubber (ACM) is an elastomer made of specific acrylate as the basic raw material, and vulcanized monomers such as chlorovinyl acetate and acrylonitrile through multi-component copolymerization. It has a saturated main bond structure, and the side chain contains polar ester groups. Therefore, acrylic rubber has good heat resistance. The long-term use temperature is 150°C, and it can be used at 200°C for a short time; it has excellent oil resistance, especially Resistance to polar oils, such as hyperbolic gear oil (containing sulfur, phosphorus, etc.); also has ozone and ultraviolet resistance properties. Based on these characteristics, automotive oil seals are mostly processed by ACM. [0003] In recent years, with the rapid development of the automobile industry and mac...
