Abstract
This production method for a cover glass for a mobile device is a production method for a cover glass for a mobile device that includes a printing step in which the surface of a glass substrate containing an alkali metal ion is subjected to printing processing, and is characterized by: utilizing the existence of a correlation between the water (water drop) contact angle in a printing area on the surface of the glass substrate subjected to printing processing during the printing step, and the printing quality in the printed glass substrate; and performing the printing step on a glass substrate having a water contact angle that fulfills the printing quality desired in the cover glass for the mobile device.
Description
The application is the patent application 201280037921.4 (applying date: on July 31st, 2012, invention and created name: portable
Formula equipment cover-plate glass and manufacture method thereof) divisional application.
Technical field
The present invention relates to for protecting mobile phone, smart phone, PDA (Personal Digital Assistant, individual number
Word assistant) etc. portable set display picture portable set cover-plate glass (cover glass) and manufacture method thereof.
Background technology
In the portable sets such as mobile phone, smart phone, PDA, in order to protect the display devices such as liquid crystal panel, at display dress
The outside put configures transparent protection board.As protection board, it is used mostly the resins such as acrylic acid, owing to the protection board of resin is easy
Bending, so needing strengthen thickness of slab or increase the gap between display device.Guarantor accordingly, as above-mentioned display device
Backplate, glass raw material popularized the cover-plate glass formed.Glass is high due to hardness, so bending is few, can aid in
Slimming.
But, rupture such characteristic owing to glass has, so for the portable set cover plate requiring high intensity
For glass, need to improve the intensity the most not enough because of slimming.As the method for improving intensity, it is proposed that to being cut into
The glass substrate of the profile of cover-plate glass carries out chemical enhanced scheme (chemical intensification treatment).This chemical intensification treatment is utilized to exist
Surface forms the ion exchange layer that compression stress works, thus suppresses bending, and obtains enough intensity, the most fragile
Damage.
In order to carry out above-mentioned chemical intensification treatment, the glass substrate forming cover-plate glass must be the group that can implement this process
Become.Specifically, as chemical intensification treatment, carry out the alkali metal ion in glass and this alkali metal ion of ratio of ionic radii
The ion-exchange treatment that big ion swaps.When therefore carrying out chemical enhanced, the glass substrate as its object must be
Composition containing alkali metal ion.
It is however generally that, cover-plate glass is the glass by cutting out multi-disc arbitrary shape from a piece of big plate glass
Substrate the glass substrate cutting out this are processed and manufacture.Thus, the situation phase of cover-plate glass is manufactured with 11 ground
Ratio, available high productivity ratio.Further, the glass substrate cut out from plate glass the works such as above-mentioned chemical intensification treatment have been carried out
After sequence, become cover-plate glass in printings such as the word desired by the enforcement of its surface or decorative patterns.Such as in patent documentation 1,
The surface of strengthening glass sheets (glass substrate) has attached implemented word or the film of decorative pattern printing, or had carried out word or decorative pattern
Baking vanish.
Patent documentation
Patent documentation 1: Japanese Unexamined Patent Publication 2003-140558 publication
Summary of the invention
It is as noted previously, as the display picture that portable set cover-plate glass is used for protecting user the most often to watch, institute
To require high quality, and must correctly print required printed patterns.As printed patterns, except example in patent documentation 1
Outside the word that shows, decorative pattern, the most also print the frame of the surrounding's fringing to viewing area.In recent years portable set cover plate glass
Glass also requires that higher level to press quality, sometimes if it occur that by ink slightly to repel the printing caused bad, then can become
For substandard product.
The present invention is in view of above-mentioned problem, it is therefore intended that provide be prevented from printing bad, improve the portable of yield rate and set
The manufacture method of standby cover-plate glass.
In order to solve above-mentioned problem, the present inventor's probe, result is learnt after manufacturing glass substrate to printing treatment
Preservation before operation impacts printing is bad.Speculate this be due in preserving from the pollutant pair of surrounding
Glass substrate attachment, the foreign body that produced by packaging material are shifted to glass baseplate surface and adhere to or because of contained by glass substrate
So-called ablation (や け) product etc. that produces with the water (dampness) in air, carbon dioxide reaction of alkali metal ion cause
Glass baseplate surface goes bad.Therefore, the present inventor furthers investigate, it is believed that by entering the surface of rotten glass substrate
Row modification and can eliminate printing bad.
But, the glass substrate being saved can not all print bad, thus real to whole glass substrates
Execute the process of modification inefficent and cause manufacturing cost to increase.Therefore it is preferred to select printing treatment in these glass substrates
