Problems solved by technology

This patent is only to set a polytetrafluoroethylene film layer on the surface of the rubber roller, and the polytetrafluoroethylene film layer is attached to the outer layer of glue. The thickness of the polytetrafluoroethylene film layer is not enough to easily cause peeling. And the hard glue layer also increases the processing difficulty of the product

Abstract

The invention relates to a production method of PTFE (Poly Tetra Fluoro Ethylene) rubber rollers. The production method comprises the following steps of enabling PTFE resin fine powder to be produced into a blank and placing the blank into a constant temperature furnace; placing the PTFE blank into a sintering furnace; enabling the outer shape, the inner shape and the size of the blank which is taken out to meet the needs of the rubber roller through machining, enabling a steel core of the rubber roller to be machined into a metal core rod and enabling the inner diameter of the blank and the outer diameter of the steel core to be machined according to the size ratio; enabling the size well-processed blank to be uniformly baked under the high temperature, enabling the blank to sleeve the well machined steel core directly after the blank is taken out, enabling the blank to sleeve the steel core firmly in an oil pressure pushing and squeezing mode and then cooling; enabling the steel molding blank which is cooled into the normal temperature to be machined into the various types of rubber rollers according to the figure. The PTFE rubber rollers have the advantages of overcoming the defects that the traditional rubber rollers are short in service life, easy to age and the like, greatly reducing the production cost of rubber roller users and being particularly suitable for industries of papermaking, galvanization, pickling and the like.

Description

technical field [0001] The invention relates to a preparation method of industrial rubber rollers. Background technique [0002] Existing industrial rubber rollers are cored with metal or other materials, and the roll-shaped products made of vulcanized rubber. Due to the poor wear resistance and heat resistance of this industrial rubber roller, corrosion and aging will occur once it is used in a harsh industrial environment, and its mechanical properties are poor, and its service life is short. [0003] Chinese invention patent (application number: 201210351099, application date: September 20, 2012) discloses an industrial rubber roller, including a metal core, the metal core is covered with an outer layer of rubber, and the outer layer of rubber is in contact with the metal A hard rubber layer is arranged between the cores, and a polytetrafluoroethylene film layer is pasted on the outer wall of the outer rubber layer. This patent is only to set a polytetrafluoroethylene f...
