Abstract
The invention discloses a pre-treatment process for glass surface chemical nickel-plating. The pre-treatment process comprises the following steps: (1) mechanical roughening: carrying out polishing treatment on the glass surface by using No.240 carborundum; (2) alkaline degreasing: putting the polished and roughened glass into a degreasing alkali solution and degreasing for 20 minutes at a temperature of 55 DEG C; (3) acid-etching roughening: putting the degreased glass into a hydrofluoric acid solution and carrying out the acid-etching roughening for 30 minutes at the temperature of 25 DEG C; (4) nickel salt activation under action of ultrasonic enhancement: soaking the glass in an activation solution which is a methanol solution of nickel acetate and sodium hypophosphite for a certain time at the temperature of 25 DEG C under the action of ultrasonic enhancement, then taking out the glass, carrying out heat treatment on the glass in a muffle furnace with the temperature of 170 DEG C and carrying out heat preservation for 30 minutes; cooling to a room temperature and then carrying out chemical sedimentation. The pre-treatment process is simple in treatment process and low in cost, hardly causes environmental pollution, and is capable of improving the activation effect of the glass surface by adopting an ultrasonic technique.
Description
Technical field
The present invention relates to a kind of pretreatment technology of chemical nickel plating, be specifically related to a kind of pretreatment technology of glass surface chemical nickel plating, belong to chemical plating nickel technology field.
Background technology
Glass, as a kind of amorphous material, has the excellent properties such as high visual transparency, high resistance, low cost of manufacture, is widely used in valve tube manufacture, the electron tube of solar water heater, the aspect such as base plate for packaging, electric light source of unicircuit.Glass is during as sealing-in base material, requirement can from different metals, the material surfaces such as alloy carry out good matched seal, because glass fragility is large, there is very large difference with the character of metal, be unfavorable for packaging sealing, can address the above problem at glass surface chemical nickel plating, but because glass is non-metallic material, in electroless nickel deposition process, its surface does not have autocatalysis activity, therefore must before chemical plating, carry out activation treatment to glass surface, what most adopted is palladium salt activating process, this technique exists cost high, complex disposal process, and use poisonous PdCl
2easily to environment.
Summary of the invention
For the problem of above-mentioned prior art existence, the invention provides a kind of pretreatment technology of glass surface chemical nickel plating, this process treatment process is simple, cost is low, environmental pollution is little, and introduces the activation effect on ultrasonic technique chilled glass surface.
To achieve these goals, the pretreatment technology of a kind of glass surface chemical nickel plating of the present invention, concrete technology comprises the following steps:
(1) mechanical alligatoring: glass surface is carried out to grinding process with 240# silicon carbide;
(2) alkaline degreasing: the glass by polishing after alligatoring is put into oil removing alkali lye is oil removing 20min under the condition of 55 DEG C in temperature;
(3) acid etching alligatoring: the glass after oil removing is put into hydrofluoric acid solution, is acid etching alligatoring 30min under 25 DEG C of conditions in temperature;
(4) ultrasound-enhanced nickel salt activation: in the ultrasound-enhanced lower activation solution that glass immersion is formed in the methanol solution of nickel acetate and sodium hypophosphite, be to soak certain hour under 25 DEG C of conditions in temperature, soak after taking out and in the retort furnace of 170 DEG C, heat-treat and be incubated 30min, can carry out electroless plating after being cooled to room temperature.
