Problems solved by technology

Generally, new rubber rollers or rubber rollers after grinding are put on the machine under this working condition. When the unit starts to produce fingerprint-resistant steel plates, irregular spot defects will appear on the surface of the steel plate in contact with the rubber rollers, which will seriously affect the surface quality of the steel plates; In this case, the spots on the surface of the steel plate exist for at least 3 to 7 days before they gradually disappear, which affects the production efficiency of the unit

Abstract

The invention discloses a high-wear-resistant high-wettability immersed rubber roller used in a plating bath of an electrogalvanizing machine set and a producing method thereof. A rubber compound used in the rubber roller includes the following components, by weight, 48.0-52.0% of synthetic rubber, 25.5-30.3% of carbon black, 1.5-2.5% of dioctyl phthalate, 2.5-2.9% of oligomer ester, 1.5-2.3% of a tackifier, 5.4-10.6% of an inorganic filling material, 2.29-3.0% of a vulcanizing agent DCP, 0.15-0.31% of sulfur, 0.15-0.18% of an accelerant NOBS, and 0.10-0.20% of an accelerant DM. The method includes the steps of: mixing the rubber compound, wrapping a metal roller core with the mixed rubber, performing vulcanization in a vulcanizing pot, and performing lathe machining. In the method, when the rubber compound is mixed, fully dispersion and combination of the materials are achieved, so that the rubber roller is high in internal and external hardness and material distribution correspondence and is high in surface roughness correspondence. The surface of the rubber roller can be wetted by an electroplating solution. The rubber roller is excellent in heat-resistant and anti-wear property. With the rubber roller, excellent running-in of the surface of the rubber roller is achieved in a short time, and electroplating surface spots due to initial processing on the roller can be reduced or eliminated, so that a steel plate is excellent in surface quality, which can satisfy the demand of high-end users.

Description

technical field [0001] The present invention relates to a submerged rubber roller and a manufacturing method thereof, more specifically, to a rubber roller used for turning the steel strip and immersing it in the electroplating solution during the production of electrogalvanized steel sheets. Grinding, temperature resistance and long-term use under this working condition (at least 6 months), more importantly, the colloid of the new rubber roller or the rubber roller after grinding has good plating solution wettability. It can effectively eliminate surface spot defects caused by the colloidal layer on the roller surface rubbing the zinc layer in a short period of time, greatly improving production efficiency and product surface quality. Background technique [0002] With the rapid development of the automobile industry and the popularity of household appliances, electro-galvanized steel sheets with high surface quality are widely used. In the gravity electrogalvanizing proce...
