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

Embodiment Construction

[0021] The specific embodiments of the present invention will be described in detail below in conjunction with the drawings.

[0022] Such as figure 1 The PTFE rubber roller shown includes a roller body and a metal core rod. The roller body adopts a cylindrical sleeve 1 made of polytetrafluoroethylene. The wall thickness of the sleeve 1 is 30mm. The metal core The rod passes through the sleeve 1 and is fixed to the sleeve 1, the surface of the metal core rod is axially provided with saber teeth, and the metal core rod and the sleeve 1 are tightly fitted and fixed by the sabre teeth. The metal core rod includes a metal tube body 2 and a connecting end 3, the wall thickness of the metal tube body 2 is 20mm, the metal tube body 2 is sleeved in the sleeve 1, and the connecting end 3 is sleeved on the metal tube body 2. The two ends are welded to the inner wall of the metal pipe body 2, a shaft head 5 is arranged on the connecting end 3, and a polytetrafluoroethylene sleeve 4 is slee...

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 method for preparing an industrial rubber roller. Background technique [0002] The existing industrial rubber rollers are roll-shaped products made of metal or other materials as the core and rubber covered by vulcanization. Due to the poor wear resistance and heat resistance of this kind of industrial rubber rollers, corrosion and aging occur when used in harsh industrial environments, and have poor mechanical properties and a short service life. [0003] A 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 glue, and the outer layer of glue is connected to the metal A hard glue layer is arranged between the cores, and a polytetrafluoroethylene film layer is attached to the outer wall of the outer glue layer. The patent is only to set a PTFE film layer on the surface of the...
