Problems solved by technology

[0002] At present, most of the sticks used in N / A hot rolling mills use rubber rollers. The molding process of the rubber rollers in this hot rolling mill is complicated, the surface treatment of the mandrel is strict, and the rubber formula design of the rubber rollers is difficult. There is no such set in China. The formula for making the rubber material of the rubber roller and the process flow for preparing the rubber roller are mature, so the rubber roller can only be obtained by importing, and the operating cost is high, so it is necessary to develop an N / A type The rubber roller on the hot rolling mill provides a set of mature silicone-based rubber formula and a molding process bonded with a brass mandrel to make up for the domestic gap

Abstract

The invention discloses a rubber roller of a hot rolling mill and a preparation method thereof. The rubber roller includes a copper-core shaft and a rubber material coating on the copper-core shaft. The rubber material of the rubber roller comprises 100-200 parts of mixed silicone rubber, 10-20 parts of precipitated silica, 5-10 parts of active calcium carbonate, 1-3 parts of iron red and 1-2 parts of 2,5-dimethyl-2,5-di(tert-butylperoxy)hexane. The rubber roller of hot rolling mill is prepared through improving a mould, preparing the rubber material of the rubber roller, pretreating the copper-core shaft, rolling the prepared rubber material of the rubber roller on the copper-core shaft, and then carrying out first-stage sulfuration and second-stage sulfuration. The rubber roller preparedby the preparation method of the invention has good comprehensive performance and the preparation method is simple and easy to operate and has high production efficiency.

Description

Technical field [0001] The invention relates to the technical field of rubber rollers and preparation methods thereof, and more specifically to rubber rollers applied to hot rolling mills and preparation methods thereof. Background technique [0002] At present, most of the sticks used on N / A hot rolling mills use rubber rollers. The rubber rollers of this hot rolling mill have complex forming processes, strict surface treatment of mandrels, and difficult rubber formula design for rubber rollers. There is no set in China. The formula for making the rubber roller rubber material and the process flow for preparing the rubber roller are mature. Therefore, the rubber roller can only be obtained by importing, and the operating cost is high. Therefore, it is necessary to develop an N / A type The rubber roller on the hot rolling mill provides a set of mature silicone rubber compound formula and a molding process bonded with the brass mandrel to make up for the domestic gap. [0003] There...
