Abstract
The invention relates to a PET film-coated plate for water tank and decoration, which provides a novel material for coating a galvanized plate surface, the novel material comprises a PET base film of food sanitation grade, then a high-molecular hot-melt particle is used for casting into a glue film, the glue film is compounded on the PET base film through a transition layer, finally a layer of high-hardness resin of food sanitation grade is sprayed on the PET surface to form a PET hot-melt film with a four-layer structure and special purpose, and the film is coated on the galvanized plate surface through a hot roller at 180 ℃ to form a novel material with corrosion resistance exceeding 304 stainless steel plates.
Description
The invention provides a novel material for coating a galvanized sheet surface, which comprises the steps of selecting a food sanitation grade PET base film, casting a high-molecular hot-melt particle into a glue film, compounding the glue film on the PET base film through a transition layer, finally spraying a layer of high-hardness food sanitation grade resin on the PET surface to form a four-layer PET hot-melt film with a special purpose, and coating the film on the galvanized sheet surface through a hot roller at 180 ℃ to form a novel material with the corrosion resistance exceeding 304 stainless steel plates.
PET tectorial membrane board, its characterized in that includes:
1. 0.15 mm PET base film;
2. 0.15 mm of high-molecular hot-melt casting film;
3. 0.1 mm composite transition layer;
4. a 0.1 millimeter scratch resistant resin layer;
5. a zinc-plated substrate.
The above description is detailed in FIG. 1, which is a cross-sectional view of a PET film-coated sheet.
Description of the drawings: FIG. 1 is a cross-sectional view of a PET film-coated sheet.
The technical field is as follows: the invention relates to a special film coating process.
Background art: the corrosion resistance of the traditional plating plates such as the zinc plating and the zinc aluminum plating plates can not be compared with that of the stainless steel material, especially when the plating plates are used as water tank plates, because the galvanic corrosion generated by the galvanic couple effect is the fatal injury of the galvanic couple effect, the plate called as the coated iron is also formed by coating resin glue on a metal plate and then coating films with different colors and patterns by an adhesion curing process, the product prepared by the process is easy to bulge, crack, age and delaminate due to poor environmental and weather resistance of the resin colloid, the PET laminated board adopts a high-molecular casting hot melt film to attach the special PET hot melt film with a four-layer structure to the metal board surface, the adhesive force can reach more than two newtons per centimeter square, is not influenced by the environment, and is evaluated by a grid-cutting cup stand, boiling water for 3 hours, baking at 200 ℃ for two hours and a neutral salt spray test for 500 hours. The film coating process can be used for coating transparent four-layer structure transparent films and special films with seven-layer structures with various color and texture requirements, thereby realizing the use requirements of different grades and cost performance, and creating a new material with excellent performance-cost ratio, wherein the price of the new material is lower than half of 304.
The specific implementation mode is as follows: a low-cost low-zinc-layer steel coil is placed on a hot-coating production line, a steel plate of the low-cost low-zinc-layer steel coil is firstly unreeled, then is preheated by a drying tunnel at 150 ℃, then enters a hot roller at 180 ℃ together with a high-molecular hot melt film with a four-layer structure, and is rolled and compounded to form a film-coated plate which is the novel material.
Claims (2)
1. The preparation method is characterized in that a high-molecular hot-melt particle is selected, a high-molecular casting hot-melt adhesive film is prepared by a casting process, and a hot-melt film with a three-layer structure is formed by compounding a transition layer and a PET (polyethylene terephthalate) base film, so that the key film preparation process is realized.
2. Meanwhile, a galvanized sheet with a chromium-free passivated surface is selected on a special film coating line, a steel sheet is preheated at 180 ℃, then the constant temperature of 150 ℃ of a hot roller is accurately controlled, and the key links of the synchronism of the two materials entering the hot roller and the position rectification performance are mastered.
