Description

technical field [0001] The invention relates to a special rubber and a preparation method thereof, in particular to a superacid-resistant rubber material and a preparation method thereof. technical background [0002] In industrial production, many equipment workpieces must work in the state of super acid medium. Such as rubber rollers used in stainless steel production lines, rubber pads in anti-corrosion equipment, etc. At present, the rubber materials used in these workpieces can generally withstand the erosion of ordinary strong acid media, but have poor resistance to superacids formed by mixing multiple strong acids (such as nitric acid, hydrochloric acid, hydrofluoric acid, etc.). Contents of the invention [0003] The object of the present invention is to provide a rubber material with good superacid resistance and abrasion resistance, as well as a method for preparing the rubber. [0004] First purpose of the present invention is achieved like this: [0005] The...
