[0020] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present utility model, and should not be construed as limiting the present utility model.

[0021] The following disclosure provides many different embodiments or examples for implementing different structures of the present utility model. To simplify the disclosure of the present utility model, components and settings of specific examples are described below. Of course, they are merely examples and are not intended to limit the present utility model.

In addition, the present utility model provides examples of various specific processes and materials, but those of ordinary skill in the art can realize the applicability of other processes and / or the use of other materials.

[0022] The paint layer structure 100 for a clay model according to an embodiment of the present utility model will be described below with reference to the accompanying drawings.

[0023] As Figure 1 shown, the paint layer structure 100 for a clay model according to an embodiment of the present utility model includes: an epoxy resin layer 1 and a high-gloss paint layer 2. The epoxy resin layer 1 is adapted to adhere to the surface of the clay model, and the high-gloss paint layer 2 is stacked on the side of the epoxy resin layer 1 facing away from the clay model. That is to say, the epoxy resin layer 1 is sprayed on the surface of the clay model, and the high-gloss paint layer 2 is sprayed on the surface of the epoxy resin layer 1. Among them, the epoxy resin has good adhesion. The paint layer structure adheres to the outer surface of the paint model through the epoxy resin layer 1, which can improve the adhesion effect between the paint layer structure and the clay model to prevent the paint layer structure from falling off the clay model. At the same time, the epoxy resin has good fluidity. Therefore, when directly attaching the epoxy resin layer 1 to the outer surface of the clay model, during the process of flowing on the outer surface of the clay model before the epoxy resin cures, it can better eliminate the defects in the production process of the clay model, and after the epoxy resin layer 1 cures, it can harden the surface of the clay model to avoid problems such as collapse, blistering, and cracking of the clay model.

[0024] In addition, the high-gloss paint layer 2 can produce a strong light reflection effect under light, and the flat surface and the defective pits reflect light at different angles. Therefore, after the high-gloss paint layer 2 is sprayed, it can highlight the defects existing on the surface of the epoxy resin layer 1, so that the defects existing on the surface of the epoxy resin layer 1 can be seen more intuitively, which is convenient for subsequent repair of the defects on the surface of the epoxy resin layer 1 to improve the surface flatness of the clay model. And after the high-gloss paint layer 2 is sprayed, it can highlight the design lines of the clay model to avoid problems such as blurred and dull lines on the surface of the clay model.

[0025] According to the paint layer structure 100 for the clay model of the embodiment of the present utility model, by attaching the epoxy resin layer 1 to the outer surface of the paint model, the adhesion effect between the paint layer structure and the clay model can be improved to prevent the paint layer structure from falling off the clay model. During the process of flowing on the outer surface of the clay model before the epoxy resin cures, the defects in the production process of the clay model can be better eliminated. At the same time, after the epoxy resin layer 1 cures, it can harden the surface of the clay model, avoiding the problems of collapse, blistering and cracking of the clay model. Moreover, after the high-gloss paint layer 2 is sprayed, the defects existing on the surface of the epoxy resin layer 1 can be highlighted, so that the defects existing on the surface of the epoxy resin layer 1 can be seen more intuitively, facilitating the subsequent repair of the surface defects of the epoxy resin layer 1 and improving the surface flatness of the clay model.

[0026] In a specific example, the epoxy resin layer 1 includes epoxy resin, epoxy resin adhesive A and epoxy resin adhesive B, and their weight ratio is epoxy resin: epoxy resin adhesive A: epoxy resin adhesive B = 3:1:1. Epoxy resin adhesive A and epoxy resin adhesive B together form epoxy resin AB adhesive. Among them, the epoxy resin can fully adhere to the surface of the clay model. The epoxy resin AB adhesive is a two-component adhesive based on epoxy resin, which has the advantages of fast curing speed, high bonding strength and high hardness after curing. Therefore, the epoxy resin layer 1 can fully adhere to the surface of the clay model, and a surface with higher hardness will be formed after the epoxy resin AB adhesive cures, thereby hardening the surface of the clay model and avoiding the problems of collapse, blistering and cracking of the clay model. At the same time, the epoxy resin can delay the curing reaction between epoxy resin adhesive A and epoxy resin adhesive B, preventing the epoxy resin layer 1 from not being able to fully cover the clay model due to the premature hardening of epoxy resin adhesive A and epoxy resin adhesive B.

[0027] In a specific example, the high-gloss paint layer 2 includes high-gloss paint, standard curing agent and standard diluent, and their weight ratio is high-gloss paint: standard curing agent: standard diluent = 2:1:0.5. Among them, the standard curing agent can react with the high-gloss paint to accelerate the curing speed of the high-gloss paint and shorten the drying time of the high-gloss paint. The standard diluent can reduce the viscosity of the high-gloss paint, facilitate the spraying of the high-gloss paint, and at the same time make the high-gloss paint flow better to ensure the uniform thickness of the high-gloss paint layer 2.

[0028] According to some embodiments of the present utility model, the epoxy resin layer 1 includes a first coating 11 and a second coating 12 which are stacked. The first coating 11 is stacked between the surface of the clay model and the second coating 12, and the thickness of the first coating 11 is less than the thickness of the second coating 12. That is to say, a relatively thin layer of epoxy resin is first sprayed on the surface of the clay model to form the first coating 11, and then a relatively thick layer of epoxy resin is sprayed on the surface of the first coating 11 to form the second coating 12. Among them, the amount of the epoxy resin sprayed for the first time is relatively small, so that the epoxy resin can flow and better fill the defects such as pits and cracks on the surface of the clay model, thereby reducing the defect degree of the surface of the clay model. At the same time, since the relatively flat first coating 11 is first formed on the surface of the clay model, the surface defects generated when the second coating 12 is sprayed on the relatively flat first coating 11 are smaller than the surface defects generated when the second coating 12 is directly sprayed on the surface of the clay model, thereby avoiding large defects on the surface of the second coating 12. Therefore, the surface flatness of the epoxy resin layer 1 can be improved. At the same time, the second coating 12 with a larger thickness can fully fill the surface defects of the first coating 11, avoid the surface defects of the first coating 11 from being exposed on the surface of the epoxy resin layer 1, and improve the surface flatness of the epoxy resin layer 1.

[0029] According to some embodiments of the present utility model, the thickness h11 of the first coating 11 satisfies: 15um ≤ h11 ≤ 25um. Among them, the smaller the thickness of the first coating 11, the smaller the defects generated by the first coating 11, the worse the adhesion effect, the smaller the hardness, the better the toughness, and the lower the cost; on the contrary, the larger the thickness of the first coating 11, the larger the defects generated by the first coating 11, the better the adhesion effect, the larger the hardness, the worse the toughness, and the higher the cost. Therefore, setting the thickness of the first coating 11 within the range of 15um to 25um can avoid the adhesion effect of the first coating 11 being too poor and the hardness being too small due to the too small thickness of the first coating 11, thereby avoiding easy detachment caused by too poor adhesion effect of the first coating 11 and easy damage caused by too small hardness of the first coating 11. At the same time, it can avoid the defects of the first coating 11 being too large, the toughness being too poor, and the cost being too high due to the too large thickness of the first coating 11, thereby avoiding poor surface flatness caused by too large defects of the first coating 11 and easy cracking caused by too poor toughness of the first coating 11. Among them, the thickness of the first coating 11 can be 15um, 18um, 20um, 23um, 25um, etc., and no specific limitation is made here.

[0030] According to some embodiments of the present utility model, the thickness h12 of the second coating 12 satisfies: 40um ≤ h12 ≤ 55um. Among them, the smaller the thickness of the second coating 12, the smaller the defects generated by the second coating 12, the worse the adhesion effect, the smaller the hardness, the better the toughness, and the lower the cost; conversely, the larger the thickness of the second coating 12, the larger the defects generated by the second coating 12, the better the adhesion effect, the larger the hardness, the worse the toughness, and the higher the cost. Therefore, setting the thickness of the second coating 12 within the range of 40um to 55um can avoid the too poor adhesion effect and too small hardness of the first coating 11 caused by the too small thickness of the second coating 12, thereby avoiding the easy shedding caused by the too poor adhesion effect of the second coating 12 and the easy damage caused by the too small hardness. At the same time, it can avoid the too large defects, too poor toughness, and too high cost of the second coating 12 caused by the too large thickness of the second coating 12, thereby avoiding the poor surface flatness caused by the too large defects of the second coating 12 and the easy cracking caused by the too poor toughness. Among them, the thickness of the second coating 12 can be 40um, 43um, 45um, 50um, 52um, 55um, etc., and no specific restrictions are made here.

[0031] According to some embodiments of the present utility model, the thickness h1 of the epoxy resin layer 1 satisfies; 55um ≤ h1 ≤ 80um. Among them, the smaller the thickness of the epoxy resin layer 1, the smaller the defects generated by the epoxy resin layer 1, the worse the adhesion effect, the smaller the hardness, the better the toughness, and the lower the cost; conversely, the larger the thickness of the epoxy resin layer 1, the larger the defects generated by the epoxy resin layer 1, the better the adhesion effect, the larger the hardness, the worse the toughness, and the higher the cost. Therefore, setting the thickness of the epoxy resin layer 1 within the range of 55um to 80um can avoid the too poor adhesion effect and too small hardness of the epoxy resin layer 1 caused by the too large thickness of the epoxy resin layer 1, thereby avoiding the easy shedding caused by the too poor adhesion effect of the epoxy resin layer 1 and the easy damage caused by the too small hardness. At the same time, it can avoid the too large defects, too poor toughness, and too high cost of the epoxy resin layer 1 caused by the too small thickness of the epoxy resin layer 1, thereby avoiding the poor surface flatness caused by the too large defects of the epoxy resin layer 1 and the easy cracking caused by the too poor toughness. Among them, the thickness of the epoxy resin layer 1 can be 55um, 58um, 60um, 69um, 76um, 80um, etc., and no specific restrictions are made here.

[0032] According to some embodiments of the present utility model, the thickness h2 of the high-gloss paint layer 2 satisfies: 30um ≤ h2 ≤ 45um. Among them, the smaller the thickness of the high-gloss paint layer 2, the smaller the defects generated by the high-gloss paint layer 2, the worse the adhesion effect, the smaller the hardness, the better the toughness, and the lower the cost; on the contrary, the larger the thickness of the high-gloss paint layer 2, the larger the defects generated by the high-gloss paint layer 2, the better the adhesion effect, the larger the hardness, the worse the toughness, and the higher the cost. Therefore, setting the thickness of the high-gloss paint layer 2 within the range of 30um to 45um can avoid the adhesion effect of the high-gloss paint layer 2 being too poor and the hardness being too small due to the too small thickness of the high-gloss paint layer 2, thereby avoiding easy peeling caused by too poor adhesion effect of the high-gloss paint layer 2 and easy damage caused by too small hardness. At the same time, it can avoid the too large defects, too poor toughness, and too high cost of the high-gloss paint layer 2 due to the too large thickness of the high-gloss paint layer 2, thereby avoiding poor surface flatness caused by too large defects of the high-gloss paint layer 2 and easy cracking caused by too poor toughness. Among them, the thickness of the high-gloss paint layer 2 can be 30um, 33um, 35um, 40um, 42um, 45um, etc., and no specific limitation is made here.

[0033] According to some embodiments of the present utility model, the paint layer structure 100 for the clay model further includes: a decorative paint layer, and the decorative paint layer includes a primer layer 3, a color paint layer 4, and a topcoat layer 5 that are sequentially laminated on the high-gloss paint layer 2. That is to say, the primer layer 3 is sprayed on the surface of the high-gloss paint layer 2, the color paint layer 4 is sprayed on the surface of the primer layer 3, and the topcoat layer 5 is sprayed on the surface of the color paint layer 4. Among them, the primer layer 3 can increase the adhesion of the color paint layer 4 and the topcoat layer 5, prevent the color paint layer 4 and the topcoat layer 5 from falling off. At the same time, the primer layer 3 can increase the surface hardness of the clay model. The color paint layer 4 can color the clay model and beautify the appearance of the clay model. The topcoat layer 5 has good gloss and light transmittance, can beautify the appearance of the clay model. At the same time, the topcoat layer 5 can block external pollutants such as moisture and dust from entering the color paint layer 4, avoid the color paint layer 4 from fading and deforming, and improve the service life of the color paint layer 4.

[0034] In a specific example, the primer layer 3 includes a primer, a standard curing agent, and a standard thinner, and their weight ratio is primer: standard curing agent: standard thinner = 4:1:2. Among them, the standard curing agent can react with the primer to accelerate the curing speed of the primer and shorten the drying time of the primer. The standard thinner can reduce the viscosity of the primer, facilitate the spraying of the primer, and at the same time can make the primer flow better to ensure the uniform thickness of the primer layer 3.

[0035] In a specific example, the color paint layer 4 includes color paint and a standard thinner, and their weight ratio is color paint : standard thinner = 1:1 - 1.5. Among them, the standard thinner can reduce the viscosity of the color paint, facilitating the spraying of the color paint, and at the same time can make the color paint flow better to ensure the uniform thickness of the color paint layer 4. Moreover, the color paint has a relatively fast curing speed and can dry quickly in the air without adding an additional standard curing agent.

[0036] According to some embodiments of the present invention, the topcoat layer 5 is a nano-ceramic paint layer. Among them, the nano-ceramic paint layer is obtained by adding nano-ceramic particles to an inorganic nano-resin, so that it has high hardness and wear resistance after curing, thereby improving the hardness and wear resistance of the topcoat layer 5, avoiding knock and damage to the paint layer structure, and improving the service life of the paint layer structure.

[0037] In a specific example, the nano-ceramic paint layer includes nano-ceramic varnish, a standard curing agent and a standard thinner, and their weight ratio is nano-ceramic varnish : standard curing agent : standard thinner = 3:1:1. Among them, the standard curing agent can react with the ceramic varnish to accelerate the curing speed of the ceramic varnish and shorten the drying time of the ceramic varnish. The standard thinner can reduce the viscosity of the ceramic varnish, facilitating the spraying of the ceramic varnish, and at the same time can make the nano-ceramic paint flow better to ensure the uniform thickness of the nano-ceramic paint layer.

[0038] According to some embodiments of the present invention, the thickness h3 of the primer layer 3 satisfies: 15um ≤ h3 ≤ 30um. Among them, the smaller the thickness of the primer layer 3, the worse the adhesion effect of the primer layer 3, the lower the hardness, the better the toughness, and the lower the cost; on the contrary, the larger the thickness of the primer layer 3, the better the adhesion effect of the primer layer 3, the higher the hardness, the worse the toughness, and the higher the cost. Therefore, setting the thickness of the primer layer 3 within the range of 15um to 30um can avoid the too poor adhesion effect and too low hardness caused by the too small thickness of the primer layer 3, thereby avoiding the easy peeling caused by the too poor adhesion effect and the easy damage caused by the too low hardness of the primer layer 3. At the same time, it can avoid the too poor toughness and too high cost caused by the too large thickness of the primer layer 3, thereby avoiding the easy cracking caused by the too poor toughness of the primer layer 3. Among them, the thickness of the primer layer 3 can be 15um, 17um, 20um, 22um, 25um, 27um, 30um, etc., and no specific limitation is made here.

[0039] According to some embodiments of the present utility model, the thickness h4 of the color paint layer 4 satisfies: 15um ≤ h4 ≤ 20um. Among them, the smaller the thickness of the color paint layer 4, the more uneven the color of the color paint layer 4, the worse the adhesion effect, the smaller the hardness, the better the toughness, and the lower the cost; conversely, the larger the thickness of the color paint layer 4, the more uniform the color of the color paint layer 4, the better the adhesion effect, the larger the hardness, the worse the toughness, and the higher the cost. Therefore, setting the thickness of the color paint layer 4 within the range of 15um to 20um can avoid the too poor adhesion effect, too uneven color, and too small hardness of the color paint layer 4 caused by the too small thickness of the color paint layer 4, thereby avoiding the easy detachment caused by the too poor adhesion effect of the color paint layer 4, the poor appearance effect caused by the too uneven color, and the easy damage caused by the too small hardness. At the same time, it can avoid the too poor toughness and too high cost of the color paint layer 4 caused by the too large thickness of the color paint layer 4, thereby avoiding the easy cracking caused by the too poor toughness of the color paint layer 4. Among them, the thickness of the color paint layer 4 can be 15um, 16um, 18um, 19um, 20um, etc., and no specific limitation is made here.

[0040] According to some embodiments of the present utility model, the thickness h5 of the topcoat layer 5 satisfies: 30um ≤ h5 ≤ 40um. Among them, the smaller the thickness of the topcoat layer 5, the better the light transmittance of the topcoat layer 5, the worse the adhesion effect, the smaller the hardness, the better the toughness, and the lower the cost; conversely, the larger the thickness of the topcoat layer 5, the worse the light transmittance of the topcoat layer 5, the better the adhesion effect, the larger the hardness, the worse the toughness, and the higher the cost. Therefore, setting the thickness of the topcoat layer 5 within the range of 30um to 40um can avoid the too poor adhesion effect and too small hardness of the topcoat layer 5 caused by the too small thickness of the topcoat layer 5, thereby avoiding the easy detachment caused by the too poor adhesion effect of the topcoat layer 5 and the easy damage caused by the too small hardness. At the same time, it can avoid the too poor light transmittance, too poor toughness, and too high cost of the topcoat layer 5 caused by the too large thickness of the topcoat layer 5, thereby avoiding the poor appearance effect caused by the too poor light transmittance of the topcoat layer 5 and the easy cracking caused by the too poor toughness. Among them, the thickness of the topcoat layer 5 can be 30um, 32um, 35um, 38um, 40um, etc., and no specific limitation is made here.
