Abstract

The invention discloses a water-tolerant oil-resistant rubber material which is prepared from the following raw materials in parts by weight: 20-30 parts of fluororubber TP (Tetrafluoroethylene-Propylene), 30-35 parts of nitrile silicone rubber, 45-50 parts of hydrogenated butyl rubber, 2-3 parts of a vulcanizing agent DCP (Dicalcium Phosphate), 2.3-3.4 parts of sulfur, 1.2-1.6 parts of epoxy resin, 1.7-2.7 parts of potassium acrylate, 5-8 parts of zinc oxide, 4-9 parts of magnesium oxide, 7-9 parts of aluminum oxide, 10-15 parts of baryte powder, 20-23 parts of calcite in powder, 7-9 parts of brucite powder, 1.6-3.4 parts of brominated polystyrene, 3.4-5.3 parts of brominated polystyrene, 2.8-3.7 parts of a rubber antioxidant 4010NA and 1-1.2 parts of a monoalkoxy titanate coupling agent. The water-tolerant oil-resistant rubber material disclosed by the invention has an excellent oil-resistant water-tolerant performance as well as flame retardant and heat resistant performances and ageing-resistant performance and further has high elasticity, high hardness and high strength.

Description

technical field [0001] The invention relates to the technical field of rubber materials, in particular to a water- and oil-resistant rubber material. Background technique [0002] Rubber materials are non-polar substances. According to the principle of similar compatibility, rubber materials are often easily dissolved in oil, which is not conducive to the use of rubber materials in oil-filled environments, and some rubber materials need to be used in high-humidity environments. The above two usage environments will change the physical and mechanical properties of the rubber material. In order to improve the water or oil resistance of rubber materials, people add various compounding components in the process of making rubber products from raw rubber. Various compounding agents have a great influence on the water and oil resistance of rubber products. The material still cannot meet the demand, and how to prepare a rubber material with excellent water and oil resistance has be...
