The colorize method of surface layer of glass
The present invention relates to a kind of processing method that adopts ion exchange principle to paint to glass.
On present market, color to glass needs more and more diversified, and the stained glass kind that can buy seldom, be only limited to blue, green, dark brown three big series, people are for reaching required purpose, taked method at glass surface plated film or pad pasting, film coating method is evaporation plating and magnetron sputtering substantially, though the magnetron sputtering plating difficult drop-off, color is single, the production unit costliness, current consumption is big, price height, evaporation coating often hydrolysis occurs and solar radiation comes off easily, and the engineering overall image is destroyed.For pad pasting, though its color is many, itself and glass surface are bonding to be by a kind of glue, in case run into water, range of temperature is big, will big area break away from, or produce the bubble that differs in size, moreover this class glue all contains harmful material.
At problem set forth above, the invention provides a kind of colorize method of surface layer of glass, its purpose is to solve the problem that aspects such as color is single, production unit is expensive, current consumption is big, price is high, plated film easily comes off exist.
The present invention comes to be realized by the following technical programs:
A kind of colorize method of surface layer of glass is characterized in that this method carries out according to the following steps:
A, press required color and select metal-salt, as solvent, prepare metal salt solution by water or ethanol as solute;
B, glass is heated, its glass body temperature reaches 450～700 ℃, keeps 20～90 seconds;
C, with the atomizing of the metal salt solution for preparing, under this temperature, be sprayed on glass surface;
D, process naturally cooling can obtain common colored glass; Can obtain painted toughened glass through quenching technology.
Select metal-salt and resene material to make mixture by required color, mixture is smeared or is sprayed on glass surface, then glass is heated, its glass body temperature reaches 450～700 ℃, keeps 20～90 seconds; Through naturally cooling, can obtain common colored glass; Can obtain painted toughened glass through quenching technology.
Used metal-salt is CuCl
2, AgNO
3, ZnS, (NH
4)
2S, FeCl
36H
2O, SnCl
45H
2O, SbCl
3, the resene material is oil, rosin etc.
Advantage of the present utility model and effect:
Cardinal principle of the present invention is to use the ion of glass surface and the ionizable metal salt of spraying or the coloring ion in the metal-resin salt to exchange, and makes coloring ion to the surface layer of glass internal divergence, reaches painted purpose.The present invention can select metal-salt or metal-resin salt to make the saline solution of required color as required, and the color of selection is arbitrarily, and is beautiful in colour, exquisitely carved, can satisfy the various needs of people to stained glass.Simple, the easily grasp of the method for saline solution preparation, technical process is few, and is easy to operate.Because after coloring ion and the surface layer of glass ion-exchange, coloring ion has diffused into surface layer of glass, thereby color difficult drop-off, colour-fast, and unharmful substance, deliquescence is not low to the reflection of light rate, can not cause ambient light contamination, the various indexs of glass are than all being improved to some extent originally after the ion-exchange.
The glass that adopts method of the present invention to develop is of many uses, allly needs simple glass band color and the colored requirement of toughened glass, all can be met, such as glass for building purposes door and window, curtain wall, automobile door and window wind shelves.Adopt production technique of the present invention, can on simple glass or toughened glass, make the pattern and the literal of nonvolatil many colors, can obtain different stained glass, make the purposes of glass more extensive with Mould Machining.

Accompanying drawing 2 is the process flow sheet of dry method of the present invention.
To the colorize method of surface layer of glass mainly is to be divided into the metal-salt thermal spraying or to be called wet spray ion diffusion (wet method) and metal-resin salt pyrolysis method or be called dry method ion diffusion (dry method).
Dry method ion diffusion technology is that the painted glass surface of need is smeared or be sprayed on to the metal-resin salt that modulates, after treating metal-resin salt drying, this glass is put into process furnace to be heated, the glass body temperature is reached between 450～700 ℃, after 20～90 seconds thermal treatment, finish metal coloring ion and surface layer of glass ion-exchange, coloring ion and to the surface layer of glass internal divergence, thus reach the purpose of glass coloring.If the glass after the processing through naturally cooling, can obtain common colored glass, as temperature being reached the softening preceding temperature of glass, then the glass after handling is carried out quenching, then can obtain painted toughened glass.
Wet method metal-salt diffusion technique is to prepare metal-salt as solute by required color, and its solvent is that water or concentration are 95% ethanol, makes metal salt solution.At first glass is heated, its body temperature reaches between 450～700 ℃, utilize pressurized air or pressurization with the metal salt solution atomizing for preparing, under this temperature, spray to glass surface, finish the exchange of metal coloring ion and surface layer of glass ionic, reach the purpose of metal ion, make glass coloring to the surface layer of glass internal divergence.If the glass after the processing through naturally cooling, can obtain common colored glass, as temperature being reached the softening preceding temperature of glass, then the glass after handling is carried out quenching, then can obtain painted toughened glass.The technological process of production of the present invention is seen accompanying drawing 1,2.
