After a period of use, the color-coated sheet will be affected by various environmental factors, and its coating performance and service life will be reduced, and it needs to be repainted. The most basic requirement for recoating is to have certain adhesion with the original coating and to have good durability. Outdoor color-coated boards can be divided into 3 categories according to the use environment. The first category is used in the natural environment and requires a certain anti-corrosion effect. Such as: the construction site is under construction, use the color-coated plate to isolate; the second category, used in the natural environment, has a certain anti-corrosion and appearance effect. Such as: prefabricated houses built outdoors; Category 3, used in some harsh environments, requires a certain period of anti-corrosion.
Color coated steel plate is a kind of composite metal plate, also known as "color organic coated steel plate", which is coated with various protective and decorative coatings after surface treatment with galvanized steel plate or cold rolled steel plate as the base. Color coated steel plate from the inside to the outside of the structural layer is cold rolled, galvanized layer, chemical conversion layer, primary coating (primer), fine coating (front and back paint). This plate surface color novel, strong adhesion, corrosion resistance and decorative, and good processing performance, can be shear, bending, drilling, riveting, crimping and so on. Commonly used coating is divided into inorganic coating, organic coating and composite coating three categories.
Color coated steel plate is mainly used as building exterior wall panel, directly used to form the wall is required to do the insulation layer; In addition, it can also be used for roofing board, corrugated board, waterproof and gas permeable board, corrosion resistant equipment and components, furniture, car shell, water baffle and so on.

According to different structures, color coated steel plates can be roughly divided into the following types.
(1) Coating steel plate
Coating steel plate is galvanized steel plate as the base, in its front and back are coated to ensure its corrosion resistance. The front side of the first layer of primer, usually epoxy primer, because of its strong adhesion to the metal, the back is also coated with epoxy or acrylic resin; The second layer used to be alkyd resin, usually polyester or acrylic paint.
(2) the PVC sheet
PVC steel plate has two types, one is produced by coating paste PVC method, known as coated PVC steel plate; The other is to have formed and printed or embossed PVC film affixed to the steel plate, known as film PVC steel plate.
PVC layer is thermoplastic, the surface can be hot processing, such as embossing can make the surface texture rich, and it also has flexibility, can be bent and other secondary processing, its corrosion resistance is also better.
PVC surface layer disadvantage is easy to aging. In order to improve this shortcoming, a new type of composite PVC steel plate with acrylic resin has been produced.
(3) Heat insulation coating steel plate
Heat insulation coating steel plate is affixed with 15 ~ 17mm thick polystyrene foam plastic or rigid polyurethane foam plastic on the back of the color coating steel plate, which can be used to improve the insulation performance of the coating steel plate.
(4) High durability coated steel plate
According to the characteristics of good aging resistance of fluorine plastics and acrylic resin, the durability and corrosion resistance of steel plate can be improved by applying high durability coated steel plate to the surface coating of steel plate.
(1) Pollution resistance. Color coated steel plate has strong pollution resistance, ketchup, lipstick, coffee drinks, edible oil and other smears on the surface of polyester coating, placed for 24 h, with washing liquid cleaning drying, the surface gloss, color no change.
(2) High temperature resistance. After continuous heating for 90 h in an oven at 120℃, the gloss and color of the coating did not change significantly.
(3) Low temperature resistance. The bending and impact resistance of colored coated steel plate do not change obviously when it is placed at -54℃ for 24 h.
(4) Boiling water resistance. After soaking in boiling water for 60 min, the surface gloss and color of all kinds of coating products do not change, and there is no bubbling, softening, expansion and other phenomena.
