Embodiment 1

[0077] 90% by weight of SiO mixed with powder 2 , 6 weight percent Al 2 o 3 , 2 weight percent ZrO 2 , 2 weight percent TiO 2 Afterwards, polyvinyl alcohol (PVA), polyethylene glycol (PEG) and oleic acid were mixed as a binder in a ratio of 5:2:3, and then 1.2% by weight of the total powder was added and spray-dried. at 600kg / cm 2 After stamping the spray-dried powder under high pressure, it was sintered at 1150°C for 6 hours.

[0078] After placing the tempered glass in a chamber that can perform vacuum decompression, place the sintered substrate at the place where electron beam evaporation is performed, and place the anti-fingerprint chemical at the place where resistance heating evaporation is performed, and then use a vacuum pump to vacuum Decompress until 1.8×10 -4 Torr, and then use argon to etch the substrate. After the substrate has been etched, adjust the chamber to 1.5 x 10 -4 Torr, 80° C., and vapor deposition of the substrate was carried out by using an ele...

Abstract

A composition for primer layer coating of a water- and oil-repellent coating layer, which is deposited so as to enhance the durability of the water- and oil-repellent coating layer, is characterized by being a mixture which comprises at least one of a silicon oxide (SiOx), a titanium (Ti) compound, an aluminum (Al) compound, and a zirconium (Zr) compound. A preparation method therefor may comprise: a step for preparing a glass or polymer substrate; a step for forming, on the substrate, a portion on which a fingerprint-resistant layer is to be deposited within the substrate by etching; a step for depositing a primer layer consisting of the composition on the surface of the substrate which comprises a portion on which the water- and oil-repellent coating layer is to be deposited; a step for forming the water- and oil-repellent coating layer on the deposited primer layer; and a step for purging the substrate on which the water- and oil-repellent coating layer is formed. The method of the present invention has an effect of having excellent wear-resistance, salt water resistance, chemical resistance and cosmetics resistance, compared to the conventional deposition.

Description

technical field [0001] The invention relates to an evaporation material composition containing a metal compound and a preparation method. [0002] In more detail, the present invention relates to the composition and preparation method of the coating layer for wire vapor deposition when waterproof and oil-proof fingerprint vapor deposition is carried out on the surface of glass and plastics. The present invention has excellent wear resistance, salt water resistance, and Drug and cosmetic resistance. Background technique [0003] Anti-fingerprint coating is a technology that specially treats the surface of substrates such as glass to prevent the adhesion of pollutants such as fingerprints, and even if the pollutants are attached, they can be easily removed by dripping. It is a technology that provides a thin film on the surface. Surface treatment technology with waterproof and oil-proof function. [0004] In many home appliances, for the parts exposed to the appearance, that...
