Problems solved by technology

[0002] At present, coatings are mainly used in the double-sided composite materials used in the construction and decoration industries in the market, but the coatings do have the following defects. First, both sides of the product need to be coated with protective coatings before they can be used, and the roller coating process is harmful to the environment and humans. Both cause very serious benzene pollution; second, there are unavoidable trace residues in some coatings, which affect human health
Third, the production process is complicated, and energy waste is serious in the production process
However, the production and application of double-sided coated steel sheets for construction and decoration has begun to rise in recent years. The production technology of this kind of double-sided coated steel plates in China is relatively backward, and the product quality is unstable.

Abstract

The invention discloses a production process of a double-sided film-coated color steel plate for a building. The method comprises the following steps: heating the front surface and the back surface ofa substrate coil material through a drying oven, with adhesive layers being formed on the front and back surfaces of the substrate coil material after the substrate coil material passes through the drying oven; coating the front surface of the treated substrate coil material with front film through an upper heat-conducting film-coating steel roller and coating the back surface of the substrate with PET film through a lower film-coating rubber roller, with the upper heat-conducting film-coating steel roller being provided with an oil path heating system inside to allow the surface temperatureof the steel roller to be 90-100 DEG C; and after the double-sided film coating, immediately spraying cold water for a cooling purpose; after spraying, performing extrusion to remove water with a wringing roller, and drying water points on the front surface and the back surface through hot air blowing, with the temperature of the cooled substrate being 25-40 DEG C, and therefore, color film layersoutside the substrate are formed, and PE protective film is attached to the color film layers at room temperature. The aging resistance, damp-heat resistance, acid resistance, alkali resistance and temperature difference resistance of the steel plate provided by the invention are obviously improved.

Description

technical field [0001] The invention relates to the technical field of steel plate preparation, in particular to a production process of a double-sided film-coated color steel plate for construction. Background technique [0002] At present, coatings are mainly used in the double-sided composite materials used in the construction and decoration industries in the market, but the coatings do have the following defects. First, both sides of the product need to be coated with protective coatings before they can be used, and the roller coating process is harmful to the environment and humans. Both cause very serious benzene pollution; the second is that some coatings have unavoidable trace residues, which affect human health. The 3rd, production process is complicated, and energy waste is serious in the production process. Therefore, the double-sided lamination technology is mainly developed in the market to meet the growing demand of the construction and decoration industries, ...
