Abstract
The invention relates to a thermal transfer printing method of a large-area metal sheet material, which is characterized in that the method comprises the following steps: metal sheet material pickling, metal sheet material alkali washing, metal sheet material phosphating film plating, metal sheet material hot washing and drying, metal sheet material base coating processing, pattern transfer printing, pattern layer top coating processing, and PE protective film application. The metal sheet material product with decorative patterns produced in the invention has very good bending performance, stamping performance, rolling performance, and formability in subsequent application processing processes, has no pattern cracking phenomenon, and has the advantages of clear pattern, good color fastness, scraping resistance, acid and alkali resistance, water boiling resistance, excellent weatherability, low production cost, environmental protection, energy saving and the like. The method of the invention is quite suitable for transfer printing processing of large-area metal sheet materials with various thicknesses.
Description
Technical field
The present invention relates to a kind of sheet metal heat-transferring method.
Background technology
At present, the design transfer on transfer film or transfer paper is mainly contained to the technique on sheet metal surface to these are several:
One is, by the design transfer on transfer film or transfer paper to sheet metal surface, through the irradiation of ultraviolet light source, by pattern cured on sheet metal.The metal plate product that this employing ultraviolet curing process obtains, its surface rigidity is better, and resistance to acids and bases is better, resistance to scraping is also better, but is greater than 90 degree bending and punching presses, or when roll extrusion embossing, pattern top layer is easy to crack, makes metal plate product extremely be unfavorable for the processed and applied in later stage.
Another kind is, after the surface of sheet metal is processed, dust, dry, reusable heat transfer printing mode, by the design transfer on transfer film or transfer paper to sheet metal surface.This technique, in the time of demoulding or de-paper, need to consume a large amount of water, and can produce a large amount of broken films or shredded paper, is difficult to process, and causes the very high and not environmental protection of production cost.
Another is, first the surface of sheet metal is processed, then coated last layer resin heat reactive resin, then transfer paper or transfer film are laid on resin bed, with transferring glue roller, patterned layer is directly stamped on transfer paper or transfer film again, makes design transfer on transfer paper or transfer film to the resin bed of sheet metal.This technique is owing to being direct printing, more easy to wear when the reverse printing of printing rubber roll, and the pattern that impression is obtained is clear not.And the pattern of transfer paper or transfer film generally has 3-4 kind color, and each color all needs a rubber roll, makes whole piece transfer printing production line very long, investment is large, and production cost is higher.
Therefore, at present existing hot reincarnation production. art also exist product can bending, punching press, roll extrusion poor performance, production cost is high, not environmental protection, the problems such as the pattern transferring lack of resolution.
Summary of the invention
The object of the present invention is to provide a kind of product bending, stampability, roll extrusion, formability good, pattern does not ftracture, and clear patterns, color fastness is good, scratch resistance, acid and alkali-resistance, water boiling resistance, weatherability are good, production cost is low, the heat-transferring method of the large-area metal sheet material of environmental protection and energy saving.
Technical scheme of the present invention is achieved in that
A heat-transferring method for large-area metal sheet material, its feature is to comprise following method step:
(1) sheet metal of given specification is as required carried out to pickling with sour water, selecting pH value is the sour water of 3-7; Pickling is complete, with clear water flushing one time;
(2) with buck, sheet metal is carried out to alkali cleaning, selecting pH value is the buck of 3-7; Alkali cleaning is complete, with clear water flushing one time;
(3) at sheet metal surface plating one deck phosphating coat, phosphating coat mass area ratio is 0.2-1.0g/m
2; Plated phosphating coat, then passivation one deck chromizing layer on phosphating coat, with potassium bichromate solution 2-4 grams per liter wiring solution-forming, soaks and disputes after taking-up in 2-3 minute at 80-90 DEG C, with clear water cleaning one time;
(4) with the hot water of 80-100 DEG C, sheet metal is carried out to heat and wash, heat washes, and dries, and bake out temperature is 140-250 DEG C;
(5) sheet metal is carried out to primary coat processing, primary coat thickness is 5-20 υ, and primary coat is complete, dries, and bake out temperature is 140-250 DEG C;
(6) transfer film or transfer paper are executed to cloth at sheet metal surface, be cooled to after normal temperature, slough the basic unit of transfer film or transfer paper, the patterned layer of transfer film or transfer paper and invested metal sheet surface;
(7) patterned layer of metal sheet surface is carried out to face and be coated with processing, it is 5-20 υ that face is coated with thickness, and face is painted with, and dries, and bake out temperature is 140-250 DEG C;
(8) upper PE diaphragm, diaphragm thickness is 0.05-0.1mm, obtains the sheet metal product with decorative pattern.
The present invention is owing to adopting technical scheme noted earlier, the sheet metal product with decorative pattern that the present invention is produced, in the application process in later stage, its buckling performance, punching performance, roll extrusion performance, processability are all very good, and pattern there will not be cracking phenomena; But also there is clear patterns, and color fastness is good, and scratch resistance, acid and alkali-resistance, water boiling resistance, weatherability are good, the advantage such as production cost is low, environmental protection and energy saving.The present invention is highly suitable for the transfer process of the large-area metal sheet material of various thickness.
Below in conjunction with detailed description of the invention, the present invention is further illustrated:
