Abstract

The invention discloses modified ethylene propylene diene monomer. The modified ethylene propylene diene monomer is prepared from the following raw materials in parts by weight: 100 parts of ethylenepropylene diene monomer; 5 to 7 parts of POE 3020; 4.5 to 5.5 parts of zinc oxide; 1 to 1.5 parts of stearic acid; 2.0 to 3.0 parts of PEG 4000; 1.0 to 2.0 parts of an anti-aging agent; 4.0 to 5.0 parts of a vulcanization accelerator; 1.0-1.5 parts of a vulcanizing agent; 2.0 to 3.0 parts of high tear resin; 10 to 20 parts of N330; 50 to 60 parts of N550; 10 to 20 parts of a white carbon black reinforcing agent; 200 to 250 parts of a filling agent; and 80-100 parts of a softener. The added POE3020 and ethylene propylene rubber are completely dissolved with each other and are not sprayed to thesurface of the rubber, so that the problem that the surface of the product is blued and colored can be completely solved.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a modified EPDM rubber and a preparation method thereof. Background technique [0002] Compared with other general-purpose rubbers, the chemical structure of the molecular chain of EPDM rubber is that its main molecular chain is composed of ethylene and propylene unit chains, which has complete saturation and high flexibility, which makes EPDM Acrylic rubber not only exhibits excellent flex resistance, resilience and low temperature resistance, but also has good chemical structure stability, excellent ozone resistance, weather aging resistance, heat resistance, good resistance to water vapor, electricity Insulation and resistance to chemical media (drugs) and other properties. Therefore, EPDM rubber has a wide range of uses, and is widely used in many aspects such as auto parts, wires and cables, and building waterproofing membranes. [0003] This project is a high-fi...
