Abstract
The invention discloses an EPDM rubber compound for a wiper bar. The EPDM rubber compound is prepared from the following raw materials in parts by weight: 45 to 60 parts of ethylene propylene dienemonomer, 10 to 25 parts of butadiene rubber, 0.1 to 0.5 part of stearic acid, 10 to 20 parts of wear-resistant carbon black, 10 to 25 parts of zincoxide, 5 to 10 parts of aluminum hydroxide, 4 to 8 parts of paraffin oil, 0.4 to 0.6 part of sulfur, 0.2 to 2.5 parts of an accelerant and 0.1 to 0.2 part of an antiager RD. According to the EPDM rubber compound disclosed by the invention, on the premise of satisfying material toughness, mechanical strength and wear resistance of the EPDM rubber compound are improved by reasonably compounding the components and precisely regulating the proportions; in addition, the EPDM rubber compound has remarkable buffering performance and low possibilities of deformation and fracture, so that the service life of the rubber compound is greatly prolonged; the industrialization cost is low, so economic benefits are favorably increased.
Description
technical field [0001] The invention relates to the technical field of rubber materials, in particular to an EPDM rubber material for a wiper strip. Background technique [0002] EPDM rubber is widely used in the automotive field because of its excellent ozone resistance, weather aging resistance and heat aging resistance, as well as good electrical insulation, heat deformation resistance and chemical corrosion resistance. Among them, the car wiper is assembled from a number of wiper strips, which are used to wipe off the raindrops and dust attached to the windshield of the vehicle, so as to improve the visibility of the driver and increase driving safety. The wiper strips are rubber materials. The rubber wiper strip can maintain sufficient humidity. Only with sufficient humidity can it have very good toughness to maintain tight contact with the window glass. However, the existing rubber materials are difficult to guarantee strength and wear resistance under the premise of ...
