[0026] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0027] Reference below Figure 1-Figure 4 The automobile model part according to the embodiment of the utility model is described.

[0028] Reference Figure 1 and Figure 2 According to the embodiment of the utility model, the car model part includes: a car model body 10 and a coating 20, wherein the coating 20 is arranged on the surface of the car model body 10. The coating 20 includes a putty layer 21 and a paint layer 22, wherein the putty layer 21 is located between the paint layer 22 and the surface of the car model body 10.

[0029] The car model body 10 is made of substitute wood, and has a pore structure 11 on the surface, such as pinholes. The putty layer 21 has good leveling properties. When the putty layer 21 is matched with the car model body 10, the putty layer 21 can better fill the holes of the car model body 10 and make the surface of the putty layer 21 smooth, which is more conducive to the matching between the putty layer 21 and other paint layers 22.

[0030] In addition, the putty layer 21 has larger molecules, less shrinkage during drying, less deformation, and less surface texture. The putty layer 21 has a greater hardness, and when combined with the car model body 10, it is not easy to collapse at the hole structure 11 on the car model body 10, and the surface is smoother.

[0031] For example, refer to Figure 3 and Figure 4 The car model parts are spliced ​​parts, which are connected by pasting with adhesive layer 34. There is no hole structure 11 on the surface of the adhesive layer 34, while there is a hole structure 11 on the nearby car model body 10. When the coating 20 is added to the car model using the existing technology, when the adhesive layer 34, the car model body 10 and the primer are matched, due to the pinhole structure 11 on the car model body 10, the insufficient hardness of the primer will collapse from the hole structure 11, causing the primer on the surface of the car model to collapse, while the surface of the adhesive layer 34 is flat, so the primer on the surface of the adhesive layer 34 is relatively protruding, resulting in the surface of the coating 20 at the pasting location protruding, the shape is not smooth and beautiful, and affects the subsequent painting process of other coatings 20. By arranging the putty layer 21 between the paint layer 22 and the surface of the car model body 10, the putty layer 21 can fully fill the hole structure 11, and the putty layer 21 has a large hardness and is not easy to collapse from the hole structure 11, so that the coating 20 on the adhesive layer 34 and the coating 20 on the car model body 10 are relatively flatter.

[0032] According to the automobile model part of the embodiment of the utility model, by setting the putty layer 21 in the coating 20 of the automobile model part, the putty layer 21 has better leveling property, so that the coating 20 can more fully fill the pinholes in the automobile model body 10. When drying, the putty layer 21 shrinks less and is not easy to produce lines on the surface. The putty layer 21 has a high hardness and is not easy to collapse at the hole structure 11. The unevenness of the surface of the coating 20 can be avoided, and the surface of the automobile model coating 20 is smoother.

[0033] According to some embodiments of the present invention, reference Figure 4 The thickness of the putty layer 21 is a, and a is not less than 100 μm. By making the thickness a of the putty layer 21 not less than 100 μm, it can be ensured that the putty layer 21 has a sufficient amount to fill the pinholes on the car model body 10, and the strength of the putty layer 21 can also be ensured, making it less likely to collapse and making the surface of the putty layer 21 smoother.

[0034] According to some embodiments of the present invention, reference Figure 4, the thickness of the putty layer 21 is a, and the range of a is 100μm to 150μm. For example, the thickness a of the putty layer 21 can be 100μm, 110μm, 120μm, 130μm, 140μm, or 150μm. By making the thickness a of the putty layer 21 not less than 100μm, it can be ensured that the putty layer 21 has a sufficient amount to fill the pinholes on the car model body 10, and the strength of the putty layer 21 can also be ensured, making it less likely to collapse and making the surface of the putty layer 21 smoother. By making the thickness a of the putty layer 21 not greater than 150μm, the putty layer 21 will not be too thick, so that the putty layer 21 will not affect the shape display of the car model body 10, thereby avoiding affecting the final effect of the car model part.

[0035] According to some embodiments of the present invention, reference Figure 2 The putty layer 21 includes a first putty layer 23 and a second putty layer 24. The second putty layer 24 is located between the first putty layer 23 and the paint layer 22. The density of the first putty layer 23 is greater than that of the second putty layer 24. The first putty layer 23 has a higher density and is located between the car model body 10 and the second putty layer 24. It can better fill the hole structure 11 on the car model body 10, and has a higher strength. It can provide sufficient support to prevent the putty layer 21 from collapsing at the hole structure 11, resulting in a depression on the surface of the putty layer 21. The second putty layer 24 has a lower density and is located between the first putty layer 23 and the paint layer 22. It can make the surface of the putty layer 21 smoother and easier to cooperate with other paint layers 22. By making the putty layer 21 include the first putty layer 23 and the second putty layer 24, and the density of the first putty layer 23 is greater than the density of the second putty layer 24, the putty layer 21 can better fill the holes, and the surface of the putty layer 21 can be smooth and easier to cooperate with other paint layers.

[0036] According to some embodiments of the present invention, reference Figure 2 , the thickness of the first putty layer 23 is greater than the thickness of the second putty layer 24. By making the first putty layer 23 greater than the thickness of the second putty layer 24, the first putty layer 23 can be sufficient to fill the pinholes on the car model body 10, and the strength of the putty layer 21 can be ensured, the putty layer 21 can be prevented from collapsing, and the surface of the putty layer 21 can be flat.

[0037] According to some embodiments of the present invention, reference Figure 2 and Figure 4 A convex structure 25 is formed on one side of the putty layer 21 facing the surface of the car model body 10, and the convex structure 25 is used to fill the hole structure 11 on the surface of the car model body 10. By making the convex structure 25 of the putty layer 21 fill the hole structure 11 on the surface of the car model body 10, the putty layer 21 will not collapse at the hole structure 11, making the surface of the putty layer 21 smoother.

[0038] According to some embodiments of the present invention, reference Figure 2 and Figure 4 The paint layer 22 includes a primer layer 26, a high-gloss paint layer 27, a color paint layer 28 and a clear coat layer 29 arranged in sequence. The primer can improve the adhesion of other paint layers 22, and can better cooperate with other paint layers 22 so that other paint layers 22 can adhere firmly. At the same time, the primer has alkali resistance and can provide anti-corrosion function. The high-gloss paint layer 27 has wear resistance, which can make the car model more wear-resistant. At the same time, the high-gloss paint layer 27 makes the surface smoother, more shiny and more beautiful. The color paint layer 28 is used to give the coating 20 color, and the clear coat layer 29 can prevent oxidation and play a role in protecting the color paint.

[0039] According to some embodiments of the present invention, reference Figure 4 The thickness of the primer layer 26 is b, and the value range of b is 15μm~30μm; the thickness of the high-gloss paint layer 27 is c, and the value range of c is 30μm~40μm; the thickness of the color paint layer 28 is d, and the value range of d is 12μm~20μm; the thickness of the varnish layer 29 is e, and the value range of e is 30μm~40μm.

[0040] For example, the thickness b of the primer can be 15 μm, 20 μm, 25 μm, or 30 μm. By limiting the thickness b of the primer to 15 μm to 30 μm, it can be ensured that the primer is thick enough to provide sufficient anti-corrosion performance. Since a putty layer 21 is provided between the paint layer 22 and the surface of the automobile model body 10, the primer in the paint layer 22 can be correspondingly thinned, so that the thickness of the primer does not exceed 30 μm, so that the color lines on the coating 20 will not be bent and blurred due to excessive thickness of the primer, thereby optimizing the visual effect of the product exterior shape, improving the quality of the paint surface, and avoiding wasting paint.

[0041] For example, the thickness c of the high gloss paint layer 27 can be 30 μm, 32 μm, 34 μm, 36 μm, 38 μm, or 40 μm. By making the thickness c of the high gloss paint layer 27 range from 30 μm to 40 μm, it can be ensured that the high gloss paint layer 27 is thick enough to provide sufficient wear resistance, but not too thick to avoid wasting paint.

[0042] For example, the thickness d of the color paint layer 28 can be 12 μm, 14 μm, 16 μm, 18 μm, or 20 μm. By making the thickness d of the color paint layer 28 in the range of 12 μm to 20 μm, it can be ensured that the color will not be exposed, and the color can be fully decorated and beautiful, and the color will not be too thick to avoid wasting paint.

[0043] For example, the thickness e of the varnish layer 29 can be 30 μm, 32 μm, 34 μm, 36 μm, 38 μm, or 40 μm. By making the thickness e of the varnish layer 29 range from 30 μm to 40 μm, it can be ensured that the varnish layer 29 is thick enough to fully protect the color paint and prevent the color paint from being oxidized, and is not too thick to avoid wasting paint.

[0044] According to some embodiments of the present invention, reference Figure 2 The surface of the putty layer 21 facing the primer layer 26 is the first surface 30, the surface of the primer layer 26 facing the high-gloss paint layer 27 is the second surface 31, the surface of the high-gloss paint layer 27 facing the color paint layer 28 is the third surface 32, and the surface of the color paint layer 28 facing the varnish layer 29 is the fourth surface 33. The roughness of the first surface 30, the second surface 31, the third surface 32, and the fourth surface 33 decreases in sequence. For example, different types of sandpaper can be used to grind so that the roughness of the first surface 30, the second surface 31, the third surface 32, and the fourth surface 33 decreases in sequence. By making the surface roughness closer to the car model body 10 higher, the adhesion between different layers can be improved, making the structure more secure and not easy to fall off.
