Problems solved by technology

[0003] EPDM rubber has excellent weather resistance properties, excellent comprehensive performance in terms of elasticity, medium resistance, high and low temperature resistance, etc. It is widely used as a cushioning and noise reduction material in passenger car interiors and air-conditioning systems. Traditional rubber mainly focuses on rubber The above material characteristics have no good way to solve and improve the total carbon emission, condensation emission, and odor emission of the rubber material body.
At present, the rubber products produced in the industry generally have a relatively large rubber smell, which emits disturbing odors such as rubber odor, especially in summer, when the vehicle is exposed to the sun outdoors, the odor emitted by the vehicle makes people feel disgusted, even disgusting. , Discomfort, customers complain a lot about it

Abstract

The invention relates to a low-emission and low-pollution EPDM (Ethylene-Propylene-Diene Monomer) rubber and a preparation method thereof, and belongs to the technical field of a weather-resistant material. The preparation method comprises the following steps of: firstly putting the EPDM rubber in an open mill, then sequentially putting zinc oxide, stearic acid and an antioxidant RD, continuously putting carbon black N550 and paraffin oil 2280 after uniformly mixing, putting an accelerating agent DTDM (Dithiodimorpholine), sulphur and a peroxide vulcanizing agent DCP (Dicumyl Peroxide) after uniformly mixing, and vulcanizing twice after mixing, thus obtaining the low-emission and low-pollution EPDM (Ethylene-Propylene-Diene Monomer) rubber product. The preparation method has the advantages of improving the unfavorable emission of rubber smells and simultaneously ensuring the intrinsically related material characteristics of the EPDM material; and a rubber formula is specially designed so that the rubber has various characteristics of low emission, wide applicability and the like.

Description

technical field [0001] The invention relates to an EPDM rubber with low emission and low pollution and a preparation method thereof, belonging to the technical field of weather-resistant materials. 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 compartment, such as GM's GME60276, Volkswagen's VW50180, and...
