The preparation method of Novel self-cleaning glassTechnical field
The present invention relates to method for glass preparation technical field, be specifically related to the preparation method of Novel self-cleaning glass.
Background technology
Glass is the indispensable integral parts of the vehicles such as buildings, automobile, is carrying many important functions, such as outward appearance, the daylighting of beautifying constructure and automobile etc., bring the open visual field and insulation or heat insulation effect to indoor and outdoor.Along with the leap of modern science and technology, the raising of people's esthetic sentiment and the pursuit to quality of the life are achieved.The glittering and translucent glass of glass is present in the every nook and cranny in people's life, and it reflects light and beauty, brings the enjoyment of material and spirit.Various glass has been come into high buildings and large mansions and huge numbers of families, as: glass tea table, dining table, screen, glass curtain wall etc.In addition, also there is a large amount of uses at various vehicles upper glasses.
A large amount of uses of glass bring bright and beautiful time, also bring many difficult problems, such as: cleaning problems, misty rain problem etc.Glass is after life-time service, and many dusts, greasy dirt can be infected with in surface, and this badly influences photopermeability and the aesthetic property of glass.Therefore need a large amount of cleanup crew to remove to carry out manual cleaning, this will consume a lot of manpower work and washings.Moreover, the cleaning of high buildings and large mansions also can threaten cleanup crew's life security, has cleanup crew to lose the life of their preciousnesses because of high-altitude application every year.In addition be infected with also can be in misty rain weather effect people's sight line at glass surface for dust, greasy dirt.Because general glass is subject to after the pollution of dust, greasy dirt, minute surface can increase the wetting angle of the globule, thereby causes its surface to overwork the tiny globule and mist pearl, and sharpness declines.Such situation just seems particularly serious to the vehicles, and it has hindered officer's sight line, badly influences traffic safety.
In prior art, have self-cleaning composition is sprayed to hot glass pane surface, final curing becomes self-cleaning film.Its system film smooth and smooth, coating speed is fast; But may solvent flashing when its consumption of materials greatly, sometimes may need repeatedly to spray, spray, surface active agent pollution environment.
Summary of the invention
The object of this invention is to provide a kind of by spray TiO on glass substrate surface2complex sol, thus make it have the functions such as super hydrophilic, decomposing organic matter and releasing negative oxygen ion, there is self-cleaning function, and the preparation method of the Novel self-cleaning glass of energy-conserving and environment-protective.
In order to solve the existing problem of background technology, the present invention is by the following technical solutions: the preparation method of Novel self-cleaning glass, and concrete steps are as follows:
(1), pre-treatment, glass substrate is cleaned with tensio-active agent washings, then rinses, dries with deionized water, stand-by;
(2), preparation TiO2complex sol, carries out proportioning by following component by weight percentage:
The positive fourth fat 6.8~20.4 of metatitanic acid
Dehydrated alcohol 72~90
Diethanolamine 1.4~5.5
Methyl ethyl diketone 0.8~1.2
Hydrochloric acid 0.1~0.3
Distilled water 0.3~1.2
(3), spray, by the above-mentioned TiO preparing2complex sol is poured in combined mist device, sprays TiO with the speed of 0.8~2.8m/min to described glass substrate surface2complex sol;
(4), dry, by glass substrate good above-mentioned spray treatment temperature be in 50~160 DEG C dry;
(5), thermal treatment, be thermal treatment in 280~330 DEG C by glass substrate after treatment above-mentioned drying in temperature, 9~15 minutes time, naturally cooling, obtains glass with clean.
The present invention has following beneficial effect: the preparation method of Novel self-cleaning glass of the present invention, comprises pre-treatment, preparation TiO2the steps such as complex sol, spraying, oven dry and thermal treatment, make it have the functions such as super hydrophilic, decomposing organic matter and releasing negative oxygen ion, have self-cleaning function, compare compared with conventional art, the light transmission rate of this glass with clean can reach more than 90%, wherein, and the TiO preparing in this preparation method2the advantages such as that complex sol has is nontoxic, tasteless, energy-conserving and environment-protective.In addition, preparation method's technique of this glass with clean is simple, cost is low, easy and simple to handle, self-cleaning effect good, is easy to promote and use.
