Description
Technical field
The present invention relates to glass reinforced processing technology field, and in particular to one kind improves display plate glass edge strength
Method.
Background technology
In recent years, the equipment such as smart mobile phone, tablet personal computer is constantly popularized and updated, and its display plate glass has been in
Reveal slimming and light-weighted development trend.The problem that being thinned to bring is the intensity meeting of display plate glass
Decline with the reduction of thickness.In production process, plate glass need to cut into it is suitably sized, it is inevitable during cutting
Plate glass glass edge can be caused to produce micro-crack, collapse a little and chipping, so as to cause the compression strength of plate glass to decline.For
It disclosure satisfy that the requirement used, it is necessary to make the glass still there is high intensity under lower thickness.In order to reach this purpose, need
The edge of glass is strengthened.
In the prior art, compressive stress layer generally is formed on its surface using chemical enhanced method to plate glass, from
And the shock resistance of protective glass is improved, to ensure its edge strength.Chinese patent such as Publication No. CN1369449A is public
A kind of process for over-all strengthening of glass has been opened, it is first passivated processing to glass surface micro-crack using hydrofluoric acid pre-treatment, then
The method that progress chemical tempering, hydrofluoric acid post processing, organosilicon protection are combined carries out integrating enhancing to glass, and this method makes
Hydrofluoric acid and organosilicon can do great damage to human body and environment, it is impossible to meet environmental requirement, and chemical attack
Cheng Jingchang causes the reduction of glass surface optical property, and the intensity that glass recovers can not be lasting, and decay is extremely serious.
The content of the invention
Above-mentioned technical problem be present for prior art, it is an object of the invention to provide one kind to improve display plate glass
The method of glass edge strength, this method avoid using corrosivity forced fluid, environmental protection and can keep strength of glass.
To achieve the above object, the present invention provides following technical scheme：
A kind of method for improving display plate glass edge strength is provided, comprised the following steps：
A) plate glass is cleaned, then dried；
B) filling out for micro-crack for filling up plate glass edge and gap is coated to the edge of the plate glass
Topping up, then stand a period of time；
C) edge of the plate glass is irradiated using laser, melts the edge of plate glass, then with cooling
Agent cools down rapidly plate glass, completes the reinforcing at the plate glass edge.
Wherein, in step a, cleaning includes pickling, alkali cleaning and washing successively.
Wherein, in step b, the filling liquid is hydroxyl polysiloxane, polyimide resin, vinyl triethoxyl silicon
The mixed liquor of alkane, acrylic acid modified alkyd resin and isopropyl titanate.
Wherein, in step b, the hydroxyl polysiloxane, polyimide resin, VTES, acrylic acid
The mass ratio of modified alkyd resin and isopropyl titanate is 2:2:3:1.
Wherein, in step b, time of repose is 30~60min.
Wherein, in step c, cooling agent is cold water or concentration is 75% alcohol.
Wherein, in step c, the laser vertical gone out using laser transmitter projects irradiates the edge of the plate glass, institute
The vertical range for stating generating laser and the edge of the plate glass is 1~10cm, and the setting of the distance can ensure that laser shines
The effect penetrated.
Beneficial effects of the present invention：
A kind of method of raising display plate glass edge strength of the present invention, including step：A) plate glass is entered
Row cleaning, is then dried；B) coat for the micro-crack of filling up plate glass edge to the edge of the plate glass and
The filling liquid in gap, then stand a period of time；C) edge of the plate glass is irradiated using laser, makes plate glass
Edge melting, then plate glass is cooled down rapidly with cooling agent, completes the reinforcing at the plate glass edge.With existing skill
Art is compared, and the present invention is first filled using the filling liquid of environmental protection to the micro-crack and gap at plate glass edge, Ran Houzai
The edge of plate glass is irradiated by laser, and then eliminates micro-crack, gap and chipping etc. caused by the edge, whole mistake
Journey avoids the forced fluid using severe corrosive a kind of HF, and environment will not be polluted, more environmentally-friendly, and this method can
Preferably keep the intensity at plate glass edge；In addition, the method for the present invention is simple to operate, quick, production efficiency is improved.
