Glass picture manufacturing process and equipment

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.

Description

technical field [0001] The invention relates to a glass painting manufacturing process and equipment. Background technique [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, th...

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
