Abstract
The invention relates to a rubber packing leather material used for a brake cylinder system. The rubber packing leather material comprises the following ingredients in parts by weight: 70-80 parts of butyronitrile rubber (N250S), 20-30 parts of butyronitrile rubber (N240S), 4-6 parts of zinc oxide (with the purity of 99.8%), 1.5-2.0 parts of stearic acid (industrial grade), 4.0-5.0 parts of modified methyl acrylic acid magnesium (modified), 1.0-2.0 parts of nano SiO2, 1.0-2.0 parts of Molijie TM-80, 2.0-2.5 parts of anti-aging agent RD (industrial grade), 0.5-1.5 parts of anti-aging agent BLE (Diphenylamine Condensation Compound) (industrial grade), 1.5-2.0 parts of vulcanizing agent DCP (Dibasic Calcium Phosphate) (industrial grade), 100-120 parts of carbon black, 15 parts of plasticizer MBA and 10 pars of plasticizer MDA. The rubber packing leather material used for the brake cylinder system, provided by the invention, is resist in grease, resist in fatigue, strong in permanent deformation capability resistance and long in service life.
Description
technical field [0001] The invention relates to a rubber material used in vehicle parts, in particular to a rubber cup material for a brake cylinder system and a preparation method thereof. Background technique [0002] The brake cylinder leather cup of railway freight cars is an important part of the vehicle braking system, which acts as a sealing brake. When the original rubber cup is used under the cold weather conditions in northern my country in winter, due to poor cold resistance, vehicle brake failure occurs many times, causing train delays, change points, outages, and even accidents. It not only disrupts the normal operation procedure of the train, but also directly threatens the safety of national property and people's lives. Therefore, how to provide an oil-resistant, low-temperature-resistant, wear-resistant rubber cup material is a technical problem to be solved in this field. Contents of the invention [0003] The technical problem to be solved by the presen...
