Abstract
The invention discloses a glass ware gold-plating process, wherein the process production process comprises the following steps of cleaning a glass ware, drying in air and collecting dust; spraying oily substrate to the glass ware; under a vacuum environment, electrically plating an aluminum film on the glass ware, and a spraying a layer of color water paint on the surface of the aluminum film of the glass ware, drying the layer of the water paint by using an oven, and cooling to the normal temperature after drying. The glass wire gold-plating technology disclosed by the invention can effectively reduce impurity residue on the surface of the glass ware by adopting ultrasonic cleaning and high-pressure pure water cleaning, can guarantee oily substrate to dry quicker and more sufficiently to guarantee that the oily substrate is tightly adsorbed with the surface of the glass ware by adopting staged type cooling, can reduce pollution of an organic solvent and strengthen adsorption between the paint and the aluminum film by adopting a water organic solvent, and can be beneficial to volatilizing residual water and solvent by adopting the staged type cooling; meanwhile, dropping due to deformation caused by quick cooling is avoided.
Description
Technical field
The present invention relates to glassware coating technique, be specifically related to the gold-plated technology of a kind of glassware.
Background technology
Plating is a kind of electron ion deposition process, is to utilize electrode to pass through electric current, and aluminium is attached on domestic glass surface fine pattern, and its object is for increasing the attractive in appearance of domestic glass, practicality.
Be to plate metal plating at domestic glass, change domestic glass surface properties or size.The gloss of giving domestic glass picture on surface is attractive in appearance, article are antirust, prevent abrasion; Improve conductance, oilness, intensity, thermotolerance, weathering resistance; Heat treated anti-carburizing, nitrogenize; The glass of size or abrasion is repaired.
Existing oil-base paint is containing the coating of organic solvent, containing benzene,toluene,xylene, formaldehyde, free TDI toxic heavy metal, poisonous and have the scent oil of stimulation paint with organic solvent, to make solvent, fire hazard while there is construction; Reduced topsoil.General oil paint cannot directly apply construction in wet surface and wet environment; To material surface, require high.3, oil-base paint cannot clean by water, and the consumption of cleaning solvent is larger.
Existing vacuum plating is to adopt under vacuum condition, by modes such as distillation or sputters, deposits the film coating method of various metals and nonmetal film at glass surface.By such mode, can obtain very thin overlay coating, speed is fast, and sticking power is good, and little to the pollution of environment.
Vacuum plating product coating is in the past because surface treatment is improper, the easy embrittlement of surface coating material or firm not, often easily come off, there is following defect in flow process: glassware surface cleaning is general only by common clear water soaking flushing, because common water quality is alkalescence, easily there is trickle solid residue to be adsorbed on surface; Oiliness substrate is inhaled in drying process, and uneven drying is even, causes oiliness substrate adsorptivity inadequate, and the aluminium lamination adsorptive power of electroplating in the middle of finally easily causing is inadequate, comes off; Priming paint adopts oiliness material, for dry, requires highly, and for the larger area of some humidity, if not dry, oiliness material is difficult for absorption; Because the too fast cooling of temperature-fall period after having sprayed paint causes each several part drying regime different, there is deformation and cause coming off.
Summary of the invention
For the problems referred to above, the present invention aims to provide that a kind of surface cleaning is clean, coating adsorptive power strong, spray the gold-plated technology of uniform glassware.
