As a special rubber, neoprene is widely used in hoses, tapes, and shock-absorbing products because of its good medium resistance, heat resistance, oil resistance, and weather resistance. The price difference, after blending with other rubber materials, its ozone resistance, flex crack resistance and comprehensive physical properties have not been improved but decreased, so that the performance of vulcanized rubber cannot meet the needs of product standards

Abstract
The invention belongs to the technical field of rubber, and particularly relates to a formula of a neoprene blended anticorrosive rubber sheet. The formula of the neoprene blended anticorrosive rubbersheet comprises the following components in parts by weight: 40-30 parts of neoprene, 60-70 parts of natural rubber, 5-10 parts of zincoxide, 1-3 parts of stearic acid, 2-3 parts of 4010NA, 1-2 parts of RD, 1-2 parts of MD, 2-3 parts of a processing auxiliary agent, 30-50 parts of carbon black, 8-10 parts of nano montmorillonite, 5-8 parts of operating oil, 3-6 parts of magnesiumoxide, 2-3 parts of sulfur, and 1-2 parts of a vulcanizationaccelerant. The rubber formula provided by the invention has better ozoneaging resistance and weather resistance, in the processing process, because an inner lubricant is used, rubber is not stuck to a roller in the processing process, and the rubber is easy to demould in the vulcanization process; and the vulcanized rubber has good physical comprehensive properties, and provides a use formula with higher cost performance for processing vulcanization of the rubber sheet.
Description
technical field [0001] The invention belongs to the technical field of rubber, and in particular relates to a formula of chloroprene rubber blended anticorrosion rubber sheet. Background technique [0002] With the development of the national economy, rubber products are more and more widely used in military industry and civilian use, and the performance requirements are also raised from simple sealing to high temperature resistance, medium oil resistance, corrosion resistance, aging resistance, flex resistance and other requirements, and On this basis, there is a deeper level of improvement. As a special rubber, neoprene is widely used in hoses, tapes, and shock-absorbing products because of its good medium resistance, heat resistance, oil resistance, and weather resistance. The price difference, after blending with other rubber materials, its ozone resistance, flex crack resistance and comprehensive physical properties have not been improved but decreased, so that the per...
