[0023] The technical solutions in the embodiments of the present utility model are clearly and completely described below in conjunction with the accompanying drawings.

[0024] Embodiment 1

[0025] like Figures 1 to 4 As shown, the utility model provides an ultra-high surface tension epoxy powder coating, comprising an aluminum-plastic plate 1, a primer layer 2 is provided on the surface of the aluminum-plastic plate 1, a tension layer 3 is provided on the upper end of the primer layer 2, and an anti-corrosion layer 4 is provided on the surface of the tension layer 3;

[0026] The tension layer 3 comprises a glue layer 31 , a mesh cloth layer 32 is disposed on the upper end of the glue layer 31 , and a weather-resistant layer 33 is disposed on the upper end of the mesh cloth layer 32 .

[0027] Further, the primer layer 2 includes a long glue layer 21, a glass crystal layer 22 is provided on the upper end of the long glue layer 21, and a glue layer 31 is provided on the upper end of the glass crystal layer 22. The viscosity of the colloid is related to the particle size, so the long colloid has a higher viscosity than the short colloid. The distance between the particles of the long colloid in the long glue layer 21 is small, so the viscosity is relatively high. The primer can increase the adhesion, and then the glass crystal layer 22 is coated on the surface of the long glue layer 21;

[0028] The glass crystal layer 22 is a surface-treated ultrafine regular glass crystal using polar glass crystal micropowder, which can float up during the thermal solidification and melting process of the powder, forming a rough upper surface when floating to the surface, thereby making the upper surface of the base coating 2 rough, so that the tension layer 3 has better adhesion.

[0029] Furthermore, the glue layer 31 is a multi-purpose glue layer. The glue for sticking the mesh cloth layer 32 on the aluminum-plastic panel 1 should be a multi-purpose glue suitable for bonding the aluminum-plastic panel 1 and the mesh cloth layer 32. The multi-purpose glue layer can not only bond the aluminum-plastic panel 1 and the mesh cloth layer 32, but also bond other building materials, such as wood, metal and plastic, etc., and has the characteristics of high strength, good water resistance and good weather resistance, making the project more solid.

[0030] Furthermore, the weather-resistant layer 33 is a polyurethane coating, which has good waterproof effect and good weather resistance.

[0031] Furthermore, the anti-corrosion layer 4 is an epoxy resin layer, and the epoxy resin layer adopts highly transparent polyester resin, so that the texture and color of the mesh cloth layer 32 can be seen, thereby facilitating the change of the coating color and making the overall aesthetics better.

[0032] Furthermore, after the base coating 2 is coated and heated by light, a glue layer 31 is coated. The base coating 2 is a thermosetting powder coating. Since the glass crystal layer 22 is made of polar glass crystal micropowder, it floats up during the thermal curing and melting process of the powder to form a rectangular stable molecular chain, thereby improving the heat dissipation effect of the coating and facilitating the coating adhesion of the upper coating of the base coating 2 to be more firm.

[0033] Working process: first, a long glue layer 21 is coated on the aluminum-plastic panel 1, and then a glass crystal layer 22 is coated on the long glue layer 21. After being heated by light, the long molecular chains of the melted glass crystal layer 22 and the long glue layer 21 float on the surface of the base coating 2 to form a rectangular molecular chain. Moreover, the surface of the base coating 2 formed by the characteristics of the glass crystal layer 22 is relatively rough, so a glue layer 31 is coated, and the glue layer 31 is used to adhere the mesh cloth layer 32. The mesh cloth layer 32 has thickness and will protrude from the surface of the aluminum-plastic panel 1 to form a 3D three-dimensional surface, which is convenient for the surface of the aluminum-plastic panel 1 to be shaped accordingly and has better aesthetics. Then, a weather-resistant layer 33 is coated on the upper end face of the mesh cloth layer 32. The polyurethane coating is used because the aluminum-plastic panel 1 is used for home cabinet doors and interior decorative panels, especially in the kitchen. Waterproofing is particularly important, and the entire coating has a long service life. Then, an anti-corrosion layer 4 is coated on the weather-resistant layer 33. The use of highly transparent polyester resin not only makes the coating beautiful, but also makes the surface concave and convex positions smoother, and can also increase the corrosion resistance of the coating.
