Description
Technical field
The utility model relates to a kind of imitative decorative pattern color coated steel sheet, and specifically a kind of high durable imitates decorative pattern color coated steel sheet.
Background technology
In order to obtain colourful decorative pattern in Coil Coating Products, adopt pre-roller coat stamp mode in the market, in original pre-roller coat color coating production technology, add one printing technology, printing-ink is transferred to painted surface, thus makes it have coloury surface profile.
The Coil Coating Products adopting said method to produce, has selected ink printing, and due to ink not UV resistant, long-time use can cause the decorative pattern of printing thin out under irradiation by sunlight until disappear.Such as, the Coil Coating Products using said method to produce is built out of doors, and use decorative pattern after a year just substantially to disappear, weather resistance is poor.
In order to pre-roller coat stamp (as imitative wood grain, marble grain) color coated steel sheet is applicable to outdoor application, need the weatherability improving color coated steel sheet, make its UV resistant performance better, the solid effect of color guarantor is more lasting.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of imitative decorative pattern color coated steel sheet, and this color coated steel sheet has high-weatherability, and color protects solid effect more lastingly, is suitable for outdoor Long-Time Service.
In order to solve the problems of the technologies described above, the technical solution of the utility model is:
A kind of high durable imitates decorative pattern color coated steel sheet, comprise basic unit, the front of described basic unit is followed successively by preprocessing layer and prime coat from inside to outside, the back side of described basic unit is followed successively by preprocessing layer, prime coat and back side enamelled coating from inside to outside, preprocessing layer outside described basic unit positive and negative is that passivating solution coating is formed, and the outer prime coat of preprocessing layer is that polyurethane primer coating is formed.
The prime coat in basic unit front is that polyurethane primer coating is formed, and the thickness of 4 ~ 6 μm has good corrosion resistance, preferably 5 μm.
Basic unit's front prime coat is outward patterned bottom chromatograph, and patterned bottom colour layer material is PE (polyester) finish paint, and the thickness of 10 ~ 14 μm can ensure weatherability, and preferred thickness is 12 μm.
Patterned bottom chromatograph is outward decorative pattern pattern layer, and decorative pattern pattern layer material is PE (polyester) finish paint, and the thickness of 1 ~ 2 μm provides bright-coloured aberration decorative pattern, and preferred thickness is 2 μm.
Decorative pattern pattern layer is outward clear coat, and clear coat material is PE (polyester) finish paint, and the thickness of 7 ~ 9 μm ensures the weatherability of decorative pattern pattern, and preferred thickness is 8 μm.
Color coated steel sheet of the present utility model has high-weatherability, and UV resistant performance is good, and color protects solid effect lastingly, is suitable for outdoor use.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the utility model structural representation.
Detailed description of the invention
As shown in Figure 1, a kind of high durable imitates decorative pattern color coated steel sheet, and basic unit 1 is zinc-plated or Al-Zn coated steel, and the front of basic unit 1 is followed successively by preprocessing layer 2, prime coat 3, patterned bottom chromatograph 4, decorative pattern pattern layer 5 and clear coat 6 from inside to outside; The back side of basic unit 1 is followed successively by preprocessing layer 7, prime coat 8 and back side enamelled coating 9 from inside to outside.
Preprocessing layer 7 outside basic unit 1 reverse side is that the passivating solution coating containing Cr VI phosphate component is formed, the prime coat 8 at basic unit 1 back side is polyurethane primer coating formation, and the back side enamelled coating 9 at basic unit 1 back side is owing to being in the back side, adopts conventional method coating to form, do not do particular/special requirement.
Preprocessing layer 2 outside basic unit 1 front is that the passivating solution coating containing Cr VI phosphate component is formed.
Basic unit 1 front is 5 μm of prime coats 3 that polyurethane primer coating is formed.
12 μm of patterned bottom chromatographs 4 that the coating of basic unit 1 front prime coat 3 outer PE (polyester) finish paint is formed.
Patterned bottom chromatograph 4 is outer is 2 μm of decorative pattern pattern layers 5 that the coating of PE (polyester) finish paint is formed.
The outer 8 μm of clear coat 6 for PE (polyester) finish paint (ultraviolet auxiliary agent can be added) coating formation of decorative pattern pattern layer 5.
The polyester finish coat of Akzo Nobel (Jiaxing) Co., Ltd selected by above-mentioned PE (polyester) finish paint.
Real after tested, the utility model product is all tested 1000 hours by ultraviolet QUV and brine spray SST tests 1000 hours, and performance is very superior, is applicable to finishing and the Side fascia of indoor and open air.
Above-described embodiment limits the utility model never in any form, and the technical scheme that the mode that every employing is equal to replacement or equivalent transformation obtains all drops in protection domain of the present utility model.
