Abstract

The invention relates to a rubber drying roller surface material and a drying roller making method. The technical problems of poor wear resistance and poor corrosion resistance of rubber drying rollers in the prior art are mainly solved in the invention. The rubber drying roller surface material is characterized in that main body rubber comprises nitrile butadiene rubber and chlorosulfonated polyethylene rubber, and the nitrile butadiene rubber comprises, by mass, 55-75% of nitrile butadiene rubber, 0.6-3.0% of sulfur, 0.1-0.3% of a promoter TT, 0.2-0.5% of a promoter M, 1.0-3.0% of an antioxidant D, 3-10% of a plasticizer SC and 25-40% of furnace carbon black; and the chlorosulfonated polyethylene rubber comprises, by mass, 50-70% of chlorosulfonated polyethylene, 10-20% of highly active magnesium oxide, 0.2-0.5% of a promoter DM, 1.0-2.0% of a promoter TRA, 1.0-3.0% of an antioxidant NBC, and 20-30% of semi-reinforcing furnace black. The material is mainly used in cold-rolled sheet enterprise electrotinning set drying rollers.

Description

technical field [0001] The invention relates to rubber products in metallurgical production equipment, in particular to a material for the surface of a rubber squeezing roller and a method for making the squeezing roller. Background technique [0002] Rubber rollers are a kind of wearing parts that are widely used in the production process of cold-rolled strip steel. In the continuous electroplating tin unit, cold-rolled strip steel needs to go through processes such as pickling, alkali washing, electroplating, rinsing, passivation, and oiling. The rubber roller needs to be exposed to a large amount of acid, alkali and organic solvent at a certain temperature. [0003] In the tinning line, in addition to the sinking roller, the squeezing roller is the rubber roller that contacts the most corrosive liquid. The squeezing roller is responsible for squeezing the corrosive liquid on the surface of the tinplate, so it needs to have good flexibility and elasticity. At the same tim...
