Description

Technical Field

[0002] The coated pre-roller coated steel sheet is a galvanized steel sheet that has been treated with a coating. It is made by covering the preheated hot-dip galvanized steel sheet with one or more layers of organic coating.

[0003] After searching, the existing Chinese patent announcement number is: CN205343981U, a glue-free PET coated steel plate, including a galvanized steel plate substrate and a composite film, the composite film includes a PET film and a colored adhesive layer coated on one side of the PET film, and the composite film is attached to one side of the galvanized steel plate substrate through the colored adhesive layer. The coated steel plate only needs to heat the galvanized steel plate substrate to about 200 degrees, and then directly attach the composite film, and the finished product can be obtained after cooling, omitting the primer curing process, and no longer requiring thermal insulation and aging treatment, shortening the cycle, reducing energy consumption, and the film-attaching process is easy to control, with a high yield rate.

[0004] In the specific implementation method of the above patent, the galvanized steel plate substrate is heated to about 200 degrees, and the composite film can be directly attached to one side of the galvanized steel plate substrate through the colored adhesive layer, without the need for thermal insulation and aging treatment, and then the anti-corrosion back paint layer is coated on the other side of the galvanized steel plate substrate to obtain the finished product. In this patent, the primer curing process is omitted, the cycle is shortened, and energy consumption is reduced. The film-applying process is easy to control and the yield rate is high. Compared with the existing ordinary PET coated steel plate production process, different patterns and specifications of plates can be quickly converted without stopping for paint change. However, this patent does not have a wear-resistant coating for protecting the surface. Other coatings on the surface of the galvanized steel plate without a wear-resistant layer are susceptible to physical damage, such as scratches, impacts and wear, which make it easier for the galvanized steel plate to corrode.

[0020] like Figure 1-Figure 3 As shown, the sealing component includes a sealing layer 4, which is made of silicate. The sealing layer 4 is designed to improve the waterproof and anti-corrosion performance of the front side of the thin steel plate 2. The silicate can effectively prevent water penetration and moisture intrusion, and protect the substrate from damage in a humid environment. The material of the adhesion layer 3 is phenol acetic acid. Phenolic acetic acid as an adhesion layer can effectively improve the adhesion of other coatings to the steel plate. It can form a good chemical bond or physical adsorption with the surface of the steel plate, providing a more stable foundation for subsequent coatings and preventing the coating from falling off and peeling off.

[0021] The material of the wear-resistant layer 1 5 is silicone, which has excellent wear resistance and can withstand friction, abrasion, scratches and other forces without being easily damaged. The material of the wear-resistant layer 2 6 is fluorocarbon resin, which also has excellent wear resistance. It can cooperate with silicone to protect the thin steel plate 2, the adhesion layer 3 and the sealing layer 4 under various severe wear environments. The rear end of the steel body 1 is fixedly connected with a flexible buffer pad 8, and the material of the flexible buffer pad 8 is foam rubber. The foam rubber is soft and elastic, can effectively absorb and disperse impact force, provide good buffering effect, and also allow the steel body 1 to better fit the wall.

[0022] Working principle: (2) After pre-roll coating, it needs to be coated, that is, a new coating is applied on the basis of the original (2). The thin steel plate 2 is the main part of the steel body 1. The adhesion layer 3 is an adhesion layer connecting the sealing layer 4 and the thin steel plate 2, which enhances the adhesion of the coating. The phenolic acetic acid forms a good chemical bond or physical adsorption with the surface of the steel plate, providing a more stable foundation for subsequent coatings to prevent the coating from falling off and peeling off. The sealing layer 4 is made of silicate, and its purpose is to seal the thin steel plate 2 to prevent water penetration and moisture intrusion, causing corrosion to the thin steel plate 2. The wear-resistant layer 5 is a wear-resistant layer made of silicone. Silicone has excellent wear resistance and can withstand friction, abrasion, scratches and other forces without being easily damaged. Damage, and the material of the wear-resistant layer 2 6 is fluorocarbon resin, which also has excellent wear resistance. It can cooperate with silicone to protect the thin steel plate 2, the adhesion layer 3 and the sealing layer 4 in various severe wear environments. The fixing hole 7 is used to fix the steel body 1, which is convenient for the bolts to pass through. The flexible buffer pad 8 is placed behind the steel body 1, which can make the steel body 1 fit the wall better. At the same time, when the steel body 1 is hit, the steel body 1 is buffered. By cooperating with the wear-resistant layer 1 5 and the wear-resistant layer 2 6, the surface of the steel body 1 is protected, which can effectively resist the influence of friction, wear and scratches. Their combination can make up for each other's shortcomings, provide stronger wear protection, and extend the service life of the coated steel plate.
