[0003] At present, my country's color-coated steel plates are mainly ordinary color-coated plates for construction. The color-coated process only stays at the level of the traditional one-coat-one-baking coating process. The variety and quantity of decorative plates such as printing and other post-coating processes It can't meet the needs of economic development, and the pattern of the printed steel plate is very easy to age, because the printed steel plate is often used outdoors, directly facing the influence of the natural environment, corrosion resistance, wear resistance, aging resistance, scratch resistance and attachment Poor performance such as focus

Embodiment Construction
[0022] The following examples are used to illustrate the present invention, but are not used to limit the scope of the present invention, all equivalent technical solutions also belong to the category of the present invention, and the patent protection scope of the present invention should be defined by each claim.
[0023] from figure 1 and figure 2 As can be seen in the figure, a continuous production process for color printed steel plates, firstly, the uncoiler 1 uncoils the steel strip coil, and degreases and removes impurities on the surface of the steel strip 19 through the degreasing cleaning device 2; the steel strip after degreasing and cleaning 19 is sent into the coating device on the steel strip surface that is made up of chemical coating machine 3 and chemical coating furnace 4, respectively last one deck protective coating 20 to the front and reverse side of steel strip 19;
[0024] The steel strip 19 of upper protective coating 20 enters successively the preli...

The invention discloses a color printed steel plate continuous production process for building, shipbuilding, automobile, furniture and electrical industries and other industries. The color printed steel plate continuous production process comprises a degreasing and washing process and a printing process. According to the color printed steel plate continuous production process, a steel strip is first treated by the degreasing and washing process and then coated with protective coatings, the protective coatings are coated with undercoat coatings and finish coatings, the front side of the steel strip is printed and is coated with a protective coating, a protective film is adhered onto the front side of the steel strip, the steel strip is coiled in a steel strip coiling machine, and the finished color printed steel plate is obtained. The two times of coating and drying before printing on the surface of the steel strip strengthen the protection of the steel plate; therefore, the antiaging performance of the steel strip is increased to more than 5,000 hours, the steel strip does not fade in more than 20 years, the corrosion resistance, wear resistance, scratch resistance and adhesion force of the printed patterns are improved considerably, and the service life of the printed steel plate is the sum of the service life of the printed patterns and the service life of the finish.
Description
technical field [0001] The invention relates to a continuous production process of colored galvanized thin steel sheets widely used in the fields of construction, home appliances, decoration, automobiles, trains, ships, etc., for surface decoration, and belongs to the technical field of printed steel sheets. Background technique [0002] Color printed steel plate is a kind of product that obtains various patterns and patterns after surface printing and film treatment of galvanized substrate after coating process. It has the characteristics of light weight, beautiful appearance, good anti-corrosion performance and processability. Substituting steel for wood and stone, high construction efficiency, energy saving and pollution prevention, etc., the surface printing can play a decorative role, and the steel substrate can play a fireproof role. my country needs to import a large amount of such materials from abroad every year, which are widely used in train interior panels, ship ...
