Problems solved by technology

[0002] The existing glass painting production process includes engraving and sanding, engraving and oil painting, engraving and engraving oil painting, laser engraving, silk screen mimeograph, oil painting on hot-melt engraving, decals, lamination, crystal carving, paint and so on. There are many kinds of oil painting or ink paint hand-painted plus primer, etc. The above-mentioned production processes have their own characteristics. They are widely used in the glass industry at home and abroad. , engraving, polishing and other technical requirements are very fine, so the yield is low; moreover, the pictures of engraved film sanding, laser engraving, and crystal engraving products only show one color, and the color is relatively monotonous; computer engraved pictures appear dull, The artistic value is not high; for painted and hand-painted products, the coloring materials used are paint, oil painting or ink pigments. Although the color is bright, it cannot be stored on the glass surface for a long time. It is not moisture-proof, not waterproof, not wear-resistant, and is easy to age , faded, peeled off, can not be used outdoors

Embodiment 1

[0054] (a) Painting on the glass: select colorless transparent glass with a thickness of 4 millimeters; select the painting pigment prepared by the above (2) formula for use, and directly paint on the glass surface to complete the drawing of the overall glass picture:

[0055] (b) Low-temperature drying: place the drawn glass painting on figure 1 The shown drying oven is dried on the bracket 13, and the drying temperature is 110°C, and the picture is completely dried;

[0056] (c) High-temperature step-by-step firing: ①Place the dried semi-finished glass painting on the figure 2 On the high-temperature-resistant gypsum powder 26 of the shown hot melting furnace, heat up, and when the temperature rises to 300°C, keep the temperature constant for 10 minutes; ②Then continue to heat up to 580°C, and keep the temperature constant for 20 minutes; ℃, keep the temperature at this temperature for 20 minutes; ④ then start to cool down, when the temperature in the furnace drops to 680 ...

Embodiment 2

[0059] (a) (b) steps are the same as in Example 1; (c) high-temperature step-by-step firing: 1. put the semi-finished glass painting on the oven dry image 3 On the high-temperature-resistant gypsum powder 26 of the shown hot melting furnace, the temperature is raised to 330°C, and the temperature is kept constant for 6 minutes; ②Then continue to heat up to 650°C, and the constant temperature is 16 minutes; ③Then heat up to 850°C, and the constant temperature is 15 minutes; When the temperature in the furnace drops to 620°C, keep the temperature constant for 6 minutes; ⑤Stop heating, so that the temperature in the furnace will automatically drop to 35°C, and then take it out of the furnace.

Embodiment 3

[0061] (a) (b) steps are the same as in Example 1; (c) high-temperature step-by-step firing: 1. put the semi-finished glass painting on the oven dry Figure 4 On the tin liquid 42 in the tin pool 41 of the shown hot melting furnace, heat up to 280°C and keep the temperature constant for 15 minutes; ②Then continue to heat up to 550°C and keep the temperature constant for 25 minutes; ③Then heat up to 750°C and keep the temperature constant for 25 minutes; Start to cool down, and when the temperature in the furnace drops to 600°C, keep the temperature constant for 8 minutes; ⑤Stop heating, so that the temperature in the furnace will automatically drop to room temperature, and take out the furnace.

[0062] The glass paintings made in Examples 2 and 3 have similar quality to the glass paintings made in Example 1. After being placed outdoors for 12 months, the color of the picture pattern is still very bright, not sticky to dust, and does not fade or fade after washing and soaking. ...

Abstract

The invention provides a process and equipment for producing a glass painting. The process comprises the following steps of: (a) painting on glass, during which, a selected painting pigment is an inorganic oxide pigment, painting of the whole glass painting is completed by directly painting on the glass surface; (b) low-temperature drying, during which, the drying temperature is less than or equal to 120 DEG C; and (c) high-temperature stepwise baking which comprises the following steps of: (1) flatwise laying a dried semi-product of the glass painting in a hot melting furnace, rising the temperature to between 280 and 330 DEG C and maintaining the temperature for 5 to 15 minutes; (2) then, rising the temperature to between 550 and 650 DEG C and maintaining the temperature for 15 to 25 minutes; (3) rising the temperature to between 750 and 850 DEG C and maintaining the temperature for 15 to 30 minutes; (4) starting to reduce the temperature, and maintaining the temperature for 5 to 15minutes when the temperature in the furnace is reduced to a temperature of between 650 and 600 DEG C; and (5) stopping heating to naturally reduce the temperature in the furnace to a temperature lessthan or equal to 50 DEG C, and taking out the product from the furnace. The equipment comprises a glass painting drying furnace and the hot melting furnace. In the glass painting produced by the method, the pattern of the painting and the glass are fused into a whole. The glass painting has the advantages of strong stereo perception, bright color of the painting pattern, dust inadhesion, washability, immersing capability, no trace after scrape, fast color and fading prevention, and can be widely applied to indoor and outdoor decoration and upholstery.
