Abstract

The invention discloses a mixed acid resistant rubber roller for a stainless steel production line and a preparation method of the mixed acid resistant rubber roller, and belongs to the fields of rubber rollers and preparation methods of the rubber rollers. A sizing material for the mixed acid resistant rubber roller disclosed by the invention comprises the following components in percentage by mass: 35.50%-48.91% of ethylene propylene terpolymer, 5.43%-23.67% of butadiene styrene rubber, 32.53%-38.04% of carbon black, 2.72%-2.96% of a plasticizer, 2.72%-2.96% of reinforcing resin, 0.16%-0.18% of an accelerant BZ, 0.16%-0.18% of an accelerant TMTD, 1.63%-1.78% of a crosslinking agent and 0.23%-0.24% of sulphur. The method comprises the following steps: mixing the sizing material; extruding, winding and encapsulating; vulcanizing by virtue of a vulcanizing boiler; and grinding and machining. The rubber roller disclosed by the invention is good in mixed acid corrosion resistance, high in strength, and high in inside and outside hardness and material distribution consistency; the roll surface is good in machinability; and the online service life reaches over 6 months.

Description

technical field [0001] The invention relates to a rubber roller and a manufacturing method thereof, more specifically, to a mixed acid-resistant (mixed acid of nitric acid and hydrofluoric acid) and electrolytic nitric acid corrosion-resistant rubber roller used in a stainless steel production line and a manufacturing method thereof. Background technique [0002] Stainless steel refers to a high-chromium alloy steel that is passive, corrosion-resistant and non-rusting in air, acid, alkali, salt and other corrosive media. Stainless steel has corrosion resistance and good formability, and its application fields continue to expand with the development of the economy. The stainless steel production process needs to go through hot rolling, cold rolling, annealing, electrolytic pickling, chemical pickling, cleaning and other processes. The mixed acid resistant immersion roll is used in the electrolytic pickling and chemical pickling tank of the anticorrosion section of the stainle...
