[0003] The reaction process is attached figure 1 As shown, usually this process needs to be aged at room temperature and humidity of 40%-60% for a week in an air atmosphere to form a wear-resistant antifouling film. Because this process lengthens the production cycle, it brings a lot of inconvenience

Abstract

The invention relates to a method for rapidly preparing a wear-resistant anti-fouling membrane; the method mainly comprises that auxiliary agent components which can release water vapor at high temperatures is added into vapor plating particles, when anti-fouling membrane components are vapor-plated to a substrate surface, new released water vapor can accelerate a reaction of a siloxy group and a substrate surface hydroxyl, so that the time of a process for forming the wear-resistant anti-fouling membrane through originally requiring to age for one week under the air atmosphere with room temperature and the humidity of 40%-60% is reduced to a few minutes, so as to save a lot of time.

Description

technical field [0001] The invention relates to a method for preparing a wear-resistant and antifouling film, in particular to a vacuum evaporation method with additives added. Background technique [0002] The vacuum surface evaporation process is the main way to prepare functional films on the surface of substrates. At present, most antifouling films (AF films) widely used in lenses, mobile phones and tablet computer displays also use this process. The main component of the AF film is a fluorine-substituted hydrocarbon-based siloxy compound. After being vapor-deposited on the surface of the substrate, it reacts with the hydroxyl groups on the surface of the substrate to form a thin film with hydrophobic and oleophobic functions, which is the so-called AF film. . [0003] The reaction process is attached figure 1 As shown, usually this process needs to be aged at room temperature and in an air atmosphere with a humidity of 40%-60% for a week to form a wear-resistant antif...
