Description
Technical field
The present invention relates to a kind of production method of stamp household electrical appliances panel, with decoration and the anti-marquis's requirement of satisfying high-grade household electrical appliances counter plate.
Background technology
Originally the household electrical appliance panel on the market has only a kind of color (being white domestic appliances usually), and this white domestic appliances outward appearance is relatively more dull.In addition, original household electrical appliances steel panel, owing to influenced by coating material restriction and coating process, using often has after a period of time finish paint to come off and the panel phenomenon of getting rusty, and has also influenced the attractive in appearance of panel.
Along with growth in the living standard, people also improving, not only require the household electrical appliances modern design to the esthetic requirement of household appliance appearance, pattern and rich color, and require that outward appearance is prolonged does not fall lacquer, colour-fast.The printed color pattern improves the effective means of high-grade household electrical appliances panel appearance beyond doubt on panel.CN201020252066.7 Chinese patent literature disclosed " blue bricks line color painted steel strip " for example, be as substrate with galvanized steel plain sheet, drawn the wood grain burr on the surface of substrate, in the substrate surface phosphatization of drawing the wood grain burr phosphate coating is arranged, be coated with successively with priming coat, printing pattern layer and finishing coat on the surface of phosphate coating, described priming coat adopts acrylic primer, and finishing coat adopts polyester finish coat, and printing pattern layer is imitative blue bricks lamina.Has anticorrosion, weather-proof, antirust, not easy to change and characteristics such as third dimension are arranged.
The printing of pattern has different process such as air brushing, offset printing, serigraphy usually.Because steel plate is compared not blotting with stationery, relatively poor with the adhesive force of printing ink, so can not directly carry out the pattern printing at surface of steel plate.Therefore, generally before the steel plate printing, to carry out primary coat earlier, promptly prime, to adhere to printing ink and to improve the steel plate corrosion resistance.Present continuous multicolor printed steel plate manufacture craft for example, adopt usually surface clean, oven dry, primary coat, oven dry, with colored roll marks flower, oven dry, face be coated with, stoving process.This technology with the continuous stamp of flower roller, because printing ink is to be coated in earlier on the colored roller that is carved with pattern, again by rubber roll with pattern transfer to steel plate, so the fineness and the third dimension of the pattern of printing on steel plate are relatively poor, being used for color steel for building can meet the demands, but is not suitable for household electrical appliances.Offset printing and serigraphy do not need can form meticulousr, clear pattern through transfer printing, and offset printing and serigraphy all belong to flat stamping technology, are unsuitable for the pattern printing of steel tape.In addition, generally only need when being used to build owing to this color steel through cutting and the die mould processing, the postorder mechanical processing technique is simple.And the household electrical appliances panel needs in process through more complicated process such as bending, punching presses, particularly in the bending machining process, often cause pull-away, the adhesive force that its reason is to constitute the printing ink of patterned layer and priming coat can not satisfy the requirement of household electrical appliances machining.
For guaranteeing that paint film does not come off in household electrical appliances panel process, normally solve at present by cover patterned plastic foil formation patterned layer at surface of steel plate, promptly earlier pattern is printed onto on the plastic foil, again plastic foil is pasted on the steel plate by adhesive.This mode is because wanting earlier on film printed patterns will carry out film more again covers, and manufacturability is poor, and cost is also high, and can produce environmentally harmful gas during subsequent treatment.Another kind of mode is transfer printing, promptly earlier by offset printing or serigraphy with pattern transfer on paper or film, paper or the figuratum one side of film are attached on the steel plate priming coat, pattern is being transferred under high temperature or the high pressure on the coating of surface of steel plate, thin out after the transfer printing as the picture on surface of the film of medium or paper, this paper or film only play the effect of transfer printing medium, have complex procedures, problem that production cost is high equally.Another kind of thinking is to increasing the auxiliary agent that improves adhesive force in bottom-coating or the printing ink, develop coating material or printing ink, but the mode of this increase auxiliary agent can increase cost.
