Abstract

The invention relates to a low smell EPDM (ethylene propylene diene monomer) for an automobile wire harness and a preparation method thereof. The EPDM is prepared by the method of: (1) firstly addingEPDM into an open mill, then adding zinc oxide, stearic acid and an antioxidant RD in order, mixing the substances evenly, then further adding carbon black and paraffin oil, mixing the substances evenly, finally adding an environment-friendly accelerator and sulfur, and conducting mixing to obtain mixed compound; (2) placing the mixed compound in a die and conducting primary vulcanization to obtain a section of vulcanized EPDM; and (3) taking out the section of vulcanized EPDM for secondary vulcanization, thus obtaining the target product EPDM. Compared with the prior art, the low smell EPDM provided by the invention meets the characteristics of rubber itself in the aspects of strength, compression set and the like, at the same time also can meet the requirements of low emission and low smell, also takes into account the low pollution characteristic, and is especially suitable for making automobile parts and the like.

Description

technical field [0001] The invention relates to the field of key parts of automobiles, in particular to a method for preparing low-odor EPDM rubber for automobile wire harnesses. Background technique [0002] With the improvement of living standards, modern humans have gradually increased their requirements for the quality of the air environment they are in. The further family popularization of passenger cars makes people not only pay attention to the living environment, but also to improve the quality of the air inside the car. Prevention and control of air pollution in cars and improvement of air quality in cars are new topics facing the development of automotive technology at home and abroad, and are also hot topics that consumers generally care about. World-renowned automobile companies have formulated their own corporate standards to monitor the odor that related substances may form in the cabin, such as SAIC GM TS-INT-001, Changan Ford WSS-M99P2222-D1, Volkswagen's VW...
