Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0027] As shown in the accompanying drawings, the Teflon rubber roller includes a roller core 1 and a rubber layer 3 coated on the roller core, and is characterized in that: the surface of the rubber layer is provided with a Teflon coating 5 .

[0028] Shown in conjunction with accompanying drawing, the production method of this Teflon rubber roller comprises the following steps:

[0029] (1) The roller core 1 is welded by seamless steel pipe, steel plate and round steel, and is finished by lathe to meet the dynamic balance requirements;

[0030] (2) Clean the roller surface of the roller core 1 with a laser cleaning system to remove rust and oil stains on the roller surface, and at the same time create a microscopic capillary structure on the roller surface to improve the bonding strength between the rubber and the roller surface;

[0031] (3) Brush t...

Abstract

The invention relates to a Teflon rubber roller and a production method thereof. In order to solve the technical problem that the current rubber roller is high in cost and poor in wear resistance, the invention provides the Teflon rubber roller which comprises a roller core and a rubber layer coving the roller core. The Teflon rubber roller is characterized in that a Teflon coating is arranged on the surface of the rubber layer. Through arranging the Teflon coating on the surface of the rubber roller, the rubber roller has non-adhesion property and high-wearing feature, so that the service life of the roller is greatly prolonged to 18-24 months, which is improved by over 50% compared with that of a silicon rubber roller. The production method of the Teflon rubber roller provided by the invention is reasonable in process and strong in operability, and can be widely applied to the production process of Teflon rubber rollers.

Description

[0001] Technical field: [0002] The invention relates to a rubber roller and a production method thereof, in particular to a Teflon rubber roller and a production method thereof. Background technique: [0003] In the plastics industry, in the manufacture of tarpaulins, various composite packaging bags, paper-plastic composites, and aluminum-plastic composites, the molten cast film produced by the machine head must be cooled synchronously by the cooling steel rod at the lower end of the machine head and the silicon rubber roller. Elastic extrusion can be evenly compounded on the substrate. Because high-temperature molten plastic often squeezes onto the rubber roller during the compounding process, the rubber roller made of common rubber can easily cause strong adhesion between the plastic and the rubber and cause parking, so the rubber roller must be made of silicone rubber. Because of the inertia and non-stickiness of silicone rubber itself, molten plastic is not easy t...
