Abstract
Description
Technical Field
[0001] The utility model relates to the field of coating structure technology, in particular to a metal paint coating structure. Background Art
[0002] Medium density fiberboard, generally refers to medium density fiberboard, is a kind of man-made board. In China, medium density fiberboard is made of agricultural waste or small firewood as the main raw materials, and its main components are wood fiber, resin glue, etc. It is an environmentally friendly furniture building material substitute for logs after hot grinding, drying, gluing, paving, hot pressing, post-treatment, and sanding.
[0003] Although MDF has the advantages of being cheap relative to logs, easy to process, uniform in material, good in physical properties, good in heat insulation, no aging, strong adhesion, etc., as people's material level improves, people's aesthetics of building materials also gradually improves, so building material manufacturers begin to set up coating structures on MDF to increase the aesthetics of MDF. Some manufacturers provide decorative functions for MDF by coating metallic paint on MDF. In order to pursue the reflective effect of metal, most manufacturers use bright metallic paint, but the paint layer formed by bright metallic paint lacks texture, so users cannot get a better visual effect when viewing MDF at a closer distance. Utility Model Content
[0004] In view of this, the present invention aims to solve the deficiencies in the prior art, and its main purpose is to provide a metallic paint coating structure, which can effectively solve the problem that the existing coating structure coated with metallic paint lacks texture, and users cannot obtain a better visual effect when viewing the medium-density fiberboard at a closer distance.
[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0006] A metallic paint coating structure comprises a substrate, a first primer layer, a first white primer layer, a second white primer layer and a matte metallic paint layer; the substrate is a medium-density fiberboard, and the surface of the substrate has a first polishing layer; the first primer layer is coated on the first polishing layer, and the first primer layer has a second polishing layer; the first white primer layer is coated on the second polishing layer, and the surface of the first white primer layer has a third polishing layer; the second white primer layer is coated on the third polishing layer, and the surface of the second white primer layer has a fourth polishing layer; the matte metallic paint layer is coated on the fourth polishing layer.
[0007] As a preferred embodiment, the model of the first primer layer is TB31007A.
[0008] As a preferred solution, the first white primer layer and the second white primer layer are both water-based two-component white primers, and the model number is TB66005.
[0009] As a preferred solution, the matte metallic paint layer is a water-based two-component solid color matte metallic paint, and its model is TB98001-10.
[0010] Compared with the prior art, the utility model has obvious advantages and beneficial effects. Specifically, it can be seen from the above technical solution that:
[0011] By coating a matte metallic paint layer on the fourth polishing layer, the matte metallic paint layer has a more metallic texture compared to the glossy metallic paint layer, and the user can still obtain a better visual effect when viewing the MDF at a closer distance. Combined with covering the first white primer layer and the second white primer layer on the substrate, the two layers of white primer layers can further reduce the influence of the original color of the wood and effectively enhance the visual effect of the matte metallic paint layer.
