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

The composition for coating a base film of a water- and oil-repellent coating film that is vapor-deposited to improve the durability of the water- and oil-repellent coating film is characterized in that the composition contains a compound of silicon oxide (SiOx) and titanium (Ti). , a mixture of at least one of aluminum (Al) compounds and zirconium (Zr) compounds. The following steps can be performed: the step of preparing a glass or polymer substrate; the step of forming the part of the above-mentioned substrate to be vapor-deposited anti-fingerprint layer by means of etching on the above-mentioned substrate; A step of evaporating a base film formed of the above-mentioned composition on the surface of a part of the above-mentioned substrate; a step of forming a water- and oil-repellent coating film on the evaporated above-mentioned base film; and removing the above-mentioned waterproof and oil-repellent coating film formed of the above-mentioned substrate steps. Compared with conventional vapor deposition, it has excellent abrasion resistance, salt water resistance, chemical resistance, and cosmetic resistance.

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...
