1. Field of the Invention
This invention relates to a surface treatment of glasses or the like, and more particularly to a transparent glasses made by a plastic injection has a first surface applied with a hard coating and a second surface applied with an anti-fog coating.
2. Description of the Prior Art
There are millions of glasses wearing by people at many different occasions, such as sunglasses, eyesight correction glasses and industry protection glasses. All of those glasses are made from plastic material, which are easy to collect steam and get scratches.
In order to correct the above-mentioned shortcomings, there are methods of applying hard coating and anti-fog coating on the glasses surface. However, the present techniques can apply only one membrane, either the hard coating or the anti-fog coating, thus, only one protection can be made to the glasses.
It is the primary objective of the present invention to provide a processing method to treat glasses or the like surface, which provides the glasses with both steam and scratch protections.
It is another objective of the present invention to provide a processing method to treat glasses or the like surface, which glasses life lasts longer.
A processing method to treat the surfaces of transparent glasses 1 of the present invention is to apply a hard coating 2 on a first surface 11 of the glasses 1 and an anti-fog coating 3 on a second surface 12 of the glasses 1, whereas edges 13 between the first surface 11 and the second surface 12 are also applied with anti-fog coating 3, as shown in
As shown in
The hard liquid 41 may be polyurethane (PU) series as the main formula, and the anti-fog liquid 61 may be silicon liquid. Due to the non-compatible character of the two liquids, the first surface 11 is applied with the hard liquid 41 and the second surface 12 is dipped into the anti-fog liquid 61 so that the first surface 11 is only applied with the hard coating 2 and the rest surfaces of the glasses 1 are applied with the anti-fog coating 3.
