Teflon paint coating method

Abstract

Disclosed is a telfon paint coating method. The telfon paint coating method includes that: telfon paint made from a same material is coated in different coatings; the telfon paint made from different materials is coated in layers so as to enable a formed final coating to be provided with characteristics of teflon in multiple varieties, due to the fact that the teflon coatings made from different materials are different in permeability and permeability characteristics, permeating speeds and permeating directions of the coatings after coating in layers are further changed, and the final telfon coating comprising a plurality of materials is enabled to be longer in permeating time and service life. A plurality of coatings are coated on the surface of a workpiece, so that flatness of the surface of the workpiece after integral coating can be improved; due to the fact that paint contrasted in colors is adopted to adjacent coatings, a coating effect can be directly obtained by observing colors of the workpiece during coating, missed points of the coatings can be obviously displayed to be found and recognized, and missing rate for coating is lowered.

Description

technical field [0001] The invention relates to the technical field of paint coating, in particular to a coating method of Teflon paint which can reduce the coating omission rate and produce a coating with long service life. Background technique [0002] Teflon coating is a fluorine coating with polytetrafluoroethylene as the matrix resin. The English name is Teflon, and it is usually called Teflon, Teflon, Teflon, Teflon, etc. transliteration). Teflon coating is a unique high-performance coating, which combines heat resistance, chemical inertness, excellent insulation stability and low friction, and has comprehensive advantages that other coatings cannot compete with. Its application flexibility makes it suitable for On products of nearly every shape and size. [0003] Teflon is divided into several basic types: PTFE, FEP, PFA, and ETFE: PTFE (polytetrafluoroethylene) non-stick coating can be used continuously at 260°C, with a maximum service temperature of 290-300°C, ext...

AI Technical Summary

Problems solved by technology

[0007] Existing coating methods only generate one coating during the coating process, and the quality of this coating directly affects the entire coating effect. Omissions are prone to occur during the coating process, and paint leaks appear on the surface of the workpiece. point, and because there are subtle differences on the surface of the workpiece during processing, when the coating is thick, it is impossible to ensure that the properties of the coating at all positions are consistent, and the flatness of the surface of the workpiece after coating is poor

[0008] In addition, the existing Teflon coating process only uses a single material coating, and the resulting coating is also a single material coating, which only has the characteristics corresponding to this material
