Description

Technical field [0001] The invention relates to a special rubber and a preparation method thereof, in particular to a rubber material capable of withstanding super acid and a preparation method thereof. technical background [0002] In industrial production, many equipment parts must work in a super acid medium. Such as the rubber roller used in the stainless steel production line, the rubber liner in the anti-corrosion equipment and so on. At present, the rubber materials used in these workpieces generally can withstand the erosion of ordinary strong acid media, but have poor resistance to super acids formed by mixing various strong acids (such as nitric acid, hydrochloric acid, hydrofluoric acid, etc.). Summary of the invention [0003] The purpose of the present invention is to provide a rubber material with good resistance to super acid and abrasion resistance, as well as a method for preparing the rubber. [0004] The first objective of the present invention is achieved as ...
