Description

Technical Field

[0001] The utility model relates to the field of coating structure technology, in particular to a sand surface 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 relatively cheap compared to logs, easy to process, uniform in material, good in physical properties, good in thermal insulation, no aging, and strong in adhesion, as people's material level improves, their aesthetics of building materials also gradually improves, so building materials companies begin to set up coating structures on MDF to increase the aesthetics of MDF. At present, there are coating structures on the market that coat MDF with sand paint. The coating structure has excellent texture and better visual effects, but over time, consumers will experience aesthetic fatigue, leading to a decline in sales. For this reason, manufacturers generally develop a new product, but developing a new product requires manpower and material resources and a long development time, resulting in increased costs. Therefore, it is necessary to propose a new solution to solve the above problems. 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 sand-finish paint coating structure, which can effectively solve the problem of consumers' aesthetic fatigue of sand-finish paint coating structures, as well as the problem of high development costs for manufacturers to develop new products.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A sand surface paint coating structure comprises a substrate, a first primer layer, a first white primer layer, a second white primer layer, a sand surface paint layer and a transparent matte 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 sand surface paint layer is coated on the fourth polishing layer, and the surface of the sand surface paint layer is formed with a sprinkled surface by a sprinkled method; the transparent matte paint layer is coated on the sand surface paint 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 sand topcoat layer is a water-based two-component sand topcoat, and its model is TB86011-10.

[0010] As a preferred solution, the transparent matte paint layer is a water-based two-component transparent matte paint, and its model is TB82009-10.

[0011] 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:

[0012] A sprinkled surface is formed by sprinkling dots on the surface of the sand paint layer. The design of the sprinkled surface brings a new visual effect to the existing sand paint coating structure, which can eliminate consumers' aesthetic fatigue of the existing sand paint coating structure. At the same time, manufacturers do not need to redevelop new products or new decorative paints. The production line only needs to add a process step without replacing or redesigning the production line, which greatly reduces the manufacturer's development cost, labor cost and time cost.
