Description

A kind of golden coated glass and its preparation process

technical field

The invention relates to the technical field of vacuum coating, in particular to a golden coated glass and a preparation process thereof.

Background technique

Golden glass products reflect wealth and luxury, so they are loved by people. At present, there are two kinds of processes in my country to achieve the golden effect on the glass surface in glass products: one is to clean the surface of glass products with industrial soft water first, then blow the water on the surface of glass products with clean air, and dry the water, and then slowly Lower the temperature of the glass product to room temperature, then use a brush to dip in gold water containing about 3% to 15% real gold to draw various patterns and characters, and finally use the glass product painted with real gold water Bake at a temperature of about 300-550°C for about 30-60 minutes and take it out to obtain a finished product. The other is to clean the surface of the glass product with industrial soft water first, then blow the water on the surface of the glass product with clean air, and dry the water, slowly lower the temperature of the glass product to room temperature, and then use the transfer printing technology to print on the surface of the glass product. Apply inorganic water-capacitive paint to make patterns, then take it and spray a layer of plastic paint, and then bake for about 60-90 minutes to take it out, and then use a vacuum evaporation aluminum plating machine to vacuum-plate a layer of 99.9% aluminum on the surface of the product Then use plastic paint to add color paste inside to adjust the simulated gold color. Spray a layer of plastic paint on the surface of the product that has been vacuum-aluminized, and finally bake it at a temperature of about 70°C for 60-90 minutes and take it out. A finished product is made.

The above two techniques are to make various golden yellow patterns on the glass surface to play a decorative effect. But there are still some deficiencies, the first one, due to the use of real gold, the price is expensive, the cost is relatively high, it is difficult for ordinary people to afford it; It contains some halogens or heavy metals, which is not friendly to the environment and the human body. On the other hand, the hardness of the gold layer on the surface of the finished product is too small, it is easy to scratch off, and the tolerance to alcohol is not high , which limits its scope of application, for example, it cannot be used as a wine glass, wine bottle, etc.

Contents of the invention

One of the objectives of the present invention is to provide a high temperature resistant, scratch resistant and alcohol resistant golden coated glass.

The second object of the present invention is to provide the preparation process of the golden coated glass.

The present invention is achieved through the following technical solutions:

A golden coated glass, comprising a glass body and a metal film layer coated on the glass body; the metal film layer is composed of three layers of metal films, with the outer surface of the glass body as a reference, and the three layers of metal film layers are successively copper inner. Membrane, titanium sandwich and titanium outer membrane.

Wherein, the copper inner film is 80%-99.999% brass plated on the glass body with a vacuum multi-arc ion machine under the protective gas of more than 99.9% argon, and the thickness of the copper inner film is 0.0005mm-0.08mm .

The titanium interlayer is 99.9%-99.999% titanium plated on the glass body with a vacuum multi-arc ion machine under the protective gas of more than 99.9% argon, and the thickness of the titanium interlayer is 0.0005mm-0.08mm. In order to increase the richness of the appearance, the titanium sandwich layer can also be replaced by pure silver, and the use of silver to reflect light can increase the aesthetics of the final product and make the plating product bright and magnificent.

The titanium outer film is 99.9%-99.999% titanium, and the thickness of the titanium interlayer is 0.0005mm-0.08mm.

The titanium outer film is a composite film composed of titanium and iron by weight percentage, wherein titanium is 90% to 99%, and iron is 1% to 10%.

The titanium outer film is plated on the glass body with a vacuum multi-arc ion machine under a nitrogen protection gas of more than 99.9%.

The preparation method of golden coated glass, the preparation steps are as follows,

Step 1, cleaning, cleaning the glass body with industrial soft water;

Step 2, baking the above-mentioned cleaned glass body to dry the moisture on its surface;

Step 3. Put the dried glass body in the vacuum multi-arc ion machine, and pump the vacuum to keep the air pressure in the operation room of the vacuum multi-arc ion machine at 1.0×10 ^-1 ~ 1.0×10 ^-3 pa; fill with argon , so that the air pressure in the operating room is kept within 1.0×10°～1.0×10 ^-3 pa;

Step 4. Release the copper target, plate the copper inner film layer, and control the temperature at 100-400°C;

Step 5. Keep the argon pressure in the operating room within 1.0×10°～1.0×10 ^-3 Pa; close the copper target, release the titanium target, plate the titanium interlayer, and control the temperature at 100～400°C;

Step 6. Vacuum out the argon, fill with nitrogen, keep the pressure of nitrogen in the operating room within 1.0×10°～1.0×10 ^-3 pa, release the titanium target, coat the titanium outer film, and control the temperature at 100～400℃;

Step 7, cooling the glass body coated with the metal film three times to normal temperature to obtain a finished product. Wherein, in the step six, the argon gas is vacuumed out, nitrogen gas is filled, the pressure of nitrogen gas in the operating room is kept within 1.0×10°～1.0×10 ^-3 pa, the titanium target is closed, and the titanium and iron combination is released. Composite target, coated with titanium outer layer, temperature controlled at 100-400°C.

The step of drawing and isolating is added between said step 2 and step 3, and the step of cleaning and isolating is also added after cooling the glass body coated with the metal film layer three times to normal temperature in corresponding step 7;

The painting isolation step is as follows: apply a quick-drying isolation powder made of Shuangfei powder on the place where the gold-plated film is not required on the glass;

The cleaning and isolation step is: washing off the isolation layer with water.

The adjustable process produces all golden glass products or glass products with a certain pattern of gold and glass natural colors.

The present invention includes a glass body and a metal film layer plated on the glass body; the metal film layer is composed of three layers of metal films, taking the outer surface of the glass body as a reference, the three layers of metal film layers are successively argon-added copper inner film, argon-added copper film, and argon-added copper film. Titanium sandwich and nitrogen-added titanium outer film. The present invention not only has bright colors, but also has low production cost; especially on the one hand, since the innermost layer is a copper film layer, and the copper film is plated under a pure argon atmosphere, so the present invention is seen from the inside of the glass product as a The natural color of transparent glass is gold, instead of the previous one, only the outer surface is gold, and the inner side is black, which greatly improves the grade and aesthetics of the product; on the other hand, because the outermost layer is pure titanium or iron When the titanium composite is plated in a pure nitrogen atmosphere, due to the chemical reaction, the original silver-gray titanium turns golden or golden-red; and the finished product prepared by the process of the present invention has the following advantages after testing:

1. High temperature resistance, will not fade or fade under high temperature of 150-200 ℃ for 2-4 hours;

2. High hardness, scratch resistance, metal utensils scratched 200 times, no fading, no scratches;

3. Alcohol corrosion resistance, soak the product in 100% ethanol for 24 hours, take it out and wipe it, it will not fade or fade.
