Method.
[background technique]
Silver color plate glass, because its special metallochrome decorative effect is widely used in the blocking material of city's interior trim
And wall surface decorative plate.At present there are two types of the conventional process methods of preparation silver color plate glass:
One is surface of plate glass is sprayed at using dedicated silver color fluorocarbon resin glass lacquer, on surface after paint curing
Silver coating, this method simple process and low cost are formed, but the coating of glass surface is organic matter, the low resistance to ag(e)ing of hardness
Can be poor, easy in use to be scratched and fallen off, normal service life is also no more than 10 years, under the conditions of intensive ultraviolet very
To less than 5 years.
Another kind is will to contain low softening point glass powder, silver pigment by the method for silk-screen printing or inkjet printing and have
The extraordinary glaze of machine aided agent is printed in glass surface, is then sintered glass by steel process, during the sintering process, has
Silver pigment is firmly adhered to glass surface by machine aided agent volatilization, low softening point glass melting, the silver color which prepares
Glass surface has the silver color glass glazings of one layer of high rigidity, and glaze layer service life is identical as plate glass matrix.
But in tempering sintering process, on the one hand, silver pigment has slight oxidative phenomena, the coloration of silver color glaze layer
It is partially dark, influence decorative effect；On the other hand, the organic additive in glaze can crack volatilization, there is certain pollution to environment.In addition
The silver color decorative layer of the glass surface either prepared using organic coating or glass glazings technique, surface smoothness is very
Height, reflecting rate is very big, both techniques can not all prepare the silver color decorative layer of matt, cannot generate the bumps on imitation stone surface
Sandstone sense effect.

Specifically, the polyethylene glycol of a certain amount of molecular weight 2000 is first added in pure water, magnesium chloride, aluminium are then added
Powder and 525 cement.In the suspension, polyethylene glycol can be adsorbed in the surface of aluminium powder and 525 cement, generate steric hindrance effect
It answers, improves the suspension of aluminium powder and cement powder.Magnesium chloride meeting partial hydrolysis in suspension, generates Mg (OH)2Micelle, Mg (OH)2
Micelle can be adsorbed in aluminium powder surface, after coating after aquation gelling during, Mg (OH)2It will form inorganic coagulation material (5Mg
(OH)2·MgCL2·8H2O), for the cementitious material in gelatinization, the relatively strong basicity environment of generation can make Al powder Surface Creation
A small amount of Al (OH)3, Al (OH)3Again with Mg (OH)2Cementitious material reaction, dehydration form Al-O-Mg key.Surface has a certain amount of
The Al powder of magnalium cementitious material can be soaked by the calcium silicates cementitious material that the hydrolysis of 525 cement generates well, improve 525 water
Cementability of the mud to aluminium powder.Silver pigment is mainly played the role of in the addition of aluminium powder in cement base coating.Big granularity silica flour
Addition form rough decorative effect mainly after cementitious coating solidification on surface, generate sandstone mechanism effect.
Step 4: prepared by cementitious coating: the cement base coating prepared by step 3 uniformly being brushed and is prepared in step 2
The modified tempered glass in surface on, tempered glass of the coating layer thickness control after 0.3-0.5mm, brushing lies against steam curing
In slot, after being conserved 4-6 hours at 80 DEG C, lies against room temperature indoor environment 7-10 days and obtained after carrying out complete aquation gelling reaction
There is the glass of silver coating.
Specifically, cement base paint brush is applied on the modified tempered glass in surface, is brushed using the method manually brushed
Tempered glass afterwards is lain against in steam curing slot, and 525 cement start to generate aquation gelatification at this time, because of tempered glass table
There is the Al of a large amount of high activity in face2O3And Fe2O3Nano particle, in the hydration process of inorganic coating, part Al2O3And Fe2O3?
The Ca (OH) that grain can be generated with hydrated cementitious2Aluminic acid dicalcium and dicalcium ferrite are generated, cementitious coating and glass can be effectively improved
Binding force, obtaining surface has the glass of silver coating, and the glass is plate glass.
It is now detailed to a kind of method for glass preparation progress for having silver coating provided by the invention with specific embodiment
