Abstract

The invention provides a process for preparing a silicon-oxygen-fluorine coating on an organic pre-coating metal plate, and the process mainly comprises: a) implementing surface cleaning and surface activation to the organic pre-coating metal plate in the plasma environment; and b) using a plasma enhancing chemical vapor deposition method to deposit and form an SixOyFz film on an organic coating of the organic pre-coating metal plate. Using the process can improve the mechanical property of the organic coating on the organic pre-coating metal plate, meanwhile improving the properties of easy surface cleaning, low frictional coefficient, beautiful shape and fingerprint resistance.

Description

technical field [0001] The present invention relates to Si x o y f z Preparation process of organic precoated metal sheet. Background technique [0002] Organically coated metal sheets (including organic pre-coated steel sheets, organic pre-coated aluminum sheets, color-coated sheets, etc.) usually have good aesthetic properties, good corrosion resistance, etc., and are widely used in home appliances, automobiles, construction and other fields. During use, the surface mechanical properties of organic coatings, especially the wear resistance and scratch resistance, have a great impact on their performance and life, and the repair costs after scratches are also very high. Therefore, it is of great significance to improve the surface wear resistance and scratch resistance of organic coatings. [0003] In order to improve the wear resistance and scratch resistance of organic coatings, the following four methods are usually used: [0004] 1) Treat the substrate surface [Refe...
