Abstract

The invention discloses a coating rubber roller for a high-grade automobile plate production line and a manufacturing method thereof, belonging to the field of rubber rollers and preparation methods thereof. The rubber for the rubber roller comprises the following components in percentage by weight: 50.7-58.1% of ethylene-propylene rubber, 29.1-38.1% of carbon black, 2.5-2.9% of naphthenic oil, 2.5-2.9% of ester oligomer, 2.5-2.9% of tackifier, 1.0-1.2% of flow promoter, 1.9-2.2% of vulcanizing agent DCP, 0.28-0.32% of sulfur, 0.18-0.20% of accelerator BZ and 0.18-0.20% of accelerator DPTT. The method comprises the following steps: compounding the rubber; winding and rubberizing; vulcanizing in a vulcanizer; and carrying out lathe grinding. In the rubber compounding process, the materials can be sufficiently dispersed and fused. the rubberizing grain color difference on the roller surface can be eliminated, the consistency of internal and external hardness of the rubber roller is high, and the material distribution consistency and roller surface roughness consistency are high, thereby satisfies the operational requirements for the coating rubber roller for a high-grade automobile plate production line.

Description

technical field [0001] The present invention relates to a coated rubber roller and a manufacturing method thereof, more specifically, to a EPDM rubber coated rubber roller used for coating a layer of special lubricating film on the surface of a steel plate during the production of high-grade automobile sheets and its method of manufacture. Background technique [0002] With the rapid development of the automobile industry and the popularization of family cars, the demand for automobile steel plates is also increasing, which drives the rapid development of the automobile steel plate industry. However, automotive steel sheets, especially automotive outer panels and door inner panels, are prone to cracks and surface coating peeling off during stamping, which not only reduces the product quality of automotive steel sheets, but also increases the production cost of automobiles. . In order to improve the stamping formability of the steel plate and reduce the production cost, a s...
