Problems solved by technology

[0006] In view of the strong corrosiveness of the mixed acid (mixed acid of nitric acid and hydrofluoric acid) in the pickling tank of the anti-corrosion section of the existing stainless steel production line, the rubber roller is corroded and soaked in the strong corrosive acid solution in the acid tank, the roller surface is sticky, and the service life is short Problem, the present invention provides a high-resistance, mixed-acid-resistant composite rubber, rubber roller and its manufacturing method. The rubber roller has a long service life under the condition of current and mixed acid working conditions, and the old roller is easy to repair and the repair cost is low.

Abstract

The invention discloses high-resistance and mixed acid resistant compounded rubber as well as a rubber roller and a preparation method of the rubber roller, belonging to the technical field of rubber rollers. The rubber roller disclosed by the invention comprises a metal roller body and compounded rubber coated outside the metal roller body; the compound rubber comprises a nitrile rubber layer, a bonding layer and a fluororubber layer from the inside out in sequence. The preparation method of the rubber roller comprises the steps of pretreating the metal roller body firstly, performing rubber coating on nitrile subbing rubber, performing presulfurization on the nitrile subbing rubber, processing the nitrile subbing rubber, coating the surface of the nitrile rubber layer with a binder, then performing rubber coating on the fluororubber layer, thereby obtaining a compounded rubber roller preliminarily; performing sulfuration on the obtained compounded rubber roller, and processing finally to obtain a finished product. The rubber roller disclosed by the invention has long on-line service life up to 7 to 8 months, for the repair of an old roller, only the fluororubber layer needs to be turned, the nitrile subbing rubber can be reused, the cost of multiple repairs is greatly lower than that of other materials, and obvious economic and social benefits are achieved.

Description

technical field [0001] The invention belongs to the technical field of rubber rollers, and relates to a high-resistance, mixed-acid-resistant composite rubber, a rubber roller and a manufacturing method thereof, more specifically, to a mixed-acid-resistant (mixed acid of nitric acid and hydrofluoric acid) used in a stainless steel production line ), a composite rubber roller resistant to electrolytic nitric acid corrosion 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. With the rapid economic development, its application fields are also expanding. In the production of stainless steel, it needs to go through processes such as hot rolling, cold rolling, annealing, electrolytic pickling, chemical pickling, cleaning, etc. The acid-resistant...
