Problems solved by technology

[0017] The birth of the patent of this invention can be said to be a matter of course, and it was also forced out by the dilemma of the market and product sales-if there is no way to increase the surface hardness of the anti-fog eyeglass lens, our anti-fog coating may not be able to continue to be promoted!

Embodiment 1

[0053] Embodiment 1: as figure 1 As shown, the matching anti-fog coating 2 is coated on the surface 1 of the substrate resin ophthalmic lens, and a layer of silicon dioxide microstructure coating 3 is vacuum-plated after curing (it can also be selected from titanium dioxide, zirconium dioxide, tantalum dioxide, oxide Indium tin, magnesium fluoride and other commonly used targets for optical glasses), can complete the manufacturing process of high hardness anti-fog glasses.

[0054] Transparent substrates such as security lenses, aviation glass, automotive glass, architectural glass, bathroom mirrors, and window products can be manufactured by this method.

Embodiment 2

[0055] Embodiment 2: as figure 2 As shown, the matching anti-fog coating 2 is coated on the substrate resin ophthalmic lens 1, and after curing, a two or more layers of silicon dioxide and metal oxides such as titanium, tantalum, zirconium, and indium tin are coated with two or more composite coatings. Microstructure coatings 3 and 4 can complete the manufacturing process of anti-fog spectacle lenses with high hardness and anti-reflection and anti-reflection functions. Of course, the selected target material should be recalculated according to the design requirements of the optical lens and the different refractive index of the target material, and the thickness of the film layer should be recalculated—it will neither damage the anti-fog effect nor affect the function of anti-reflection and anti-reflection. Other anti-fog products that require anti-reflection and anti-reflection functions can be manufactured according to this method.

Embodiment 3

[0056] Embodiment 3: as figure 1 As shown, the matching hydrophilic (hydrophobic) coating 2 is coated on the stainless steel surface 1 of the base material, and after curing, a layer of stainless steel microstructure coating 3 is vacuum-plated, and the high-hardness hydrophilic and self-cleaning stainless steel product can be completed. Manufacturing process.

[0057] The target material and base material can be selected differently, for example, the stainless steel base material chooses a silica target material, etc., whichever meets the product design and use requirements.

Abstract

A method for increasing the surface hardness of a hydrophilic anti-fogging coating, a hydrophilic self-cleaning coating and a hydrophobic self-cleaning coating comprises the following steps: the threefunctional coatings are used as primers, and a high-hardness material is used as a target material, one or more high-hardness coatings with microstructure features covers on the surface of the targetmaterial by using vacuum coating technology, so that the surface hardness of a product increases from HB to more than 5H. Meanwhile, the microstructure of the high-hardness coating per se indicates that gaps exist between the gas-phase deposited target material particles used for preparing the coatings, and the gaps can become the release passage and the outlet of the functional components such as fog-proof, hydrophile, hydrophobe and the like, thereby not influencing the hydrophilic anti-fogging effect of the product per se or the functions of hydrophilic self-cleaning and hydrophobic self-cleaning. Besides, if the target material is selected properly, the microstructure coatings can also have a certain anti-reflection effect, and a coating with a microstructure is manufactured by superposing a plurality of target materials with different refractive indexes, and the anti-reflection effect can be better. The crux of the method is to select good functional paint.

Description

Technical field [0001] The patent of the present invention belongs to a process method for improving the quality of functional products, and is an applied technology that comes from practice and returns to practice. The implementation of the patent of this invention can achieve the purpose of increasing the surface hardness of functional products, and small technologies can solve big problems. Background technique [0002] 1. It is realistic and urgent to increase the surface hardness of functional products! [0003] At present, the anti-fog or self-cleaning functions implemented on anti-fog products and hydrophilic self-cleaning products are basically realized by using hydrophilic coatings. [0004] The difference between the anti-fog coating and the hydrophilic self-cleaning coating is that the water molecule contact angle of the anti-fog coating is between 0-14 degrees, and the water molecule contact angle of the hydrophilic self-cleaning coating is between 0-90 degrees ...
