[0048] Reference Figure 1 and Figure 2An embodiment of the present application provides a wood floor surface coating method, comprising the following steps:
[0049] S1: wire drawing, shallow wire drawing is adopted to form a wire drawing groove 110 on the surface of the substrate 100;
[0050] S2: primer coating, comprising multiple primer coating procedures and forming a primer layer 200 on the surface of the substrate 100, the primer layer 200 is attached to the inner wall of the wire drawing groove 110, wherein at least one primer coating procedure adopts a silica gel roller to perform primer roller coating, and at least one primer coating procedure adopts a brush roller to perform secondary roller coating on the primer on the surface of the substrate 100 after the primer roller coating;
[0051] S3: topcoat coating, roller coating a topcoat on the primer layer 200 to form a topcoat layer 300, the topcoat layer 300 covers the primer layer 200 and forms a texture groove 120 at the wire drawing groove 110, the depth of the texture groove 120 is less than the depth of the wire drawing groove 110.
[0052] In the wood floor surface coating method of the embodiment of the present application, the surface of the base plate 100 is subjected to the drawing treatment by adopting the light drawing process, compared with the conventional drawing process, the light drawing process can process the shallower drawing groove 110 on the surface of the base plate 100, which not only can facilitate the subsequent paint filling of the primer coating and the topcoat coating to be more uniform, but also can reduce the problem that the dirt accumulates and is not convenient to clean due to the too deep drawing groove 110 in the actual use process of the wood floor. Secondly, in the primer coating process, the primer roller coating is adopted by the silica gel roller in at least one primer coating process, compared with the conventional paint roller, the silica gel roller is softer, so that the primer can be filled into the drawing groove 110. After the primer roller coating, the primer on the surface of the base plate 100 is subjected to the secondary roller coating by the brush roller, so that the primer on the surface of the base plate 100 can be brought into the drawing groove 110 by the brush roller and the primer can be more uniformly attached to the inner wall of the drawing groove 110. The brush roller can also reinforce the primer on the surface of the base plate 100, so that the primer filling on the surface of the base plate 100 is more uniform. In addition, the texture groove 120 can be formed on the surface of the topcoat layer 300 corresponding to the position of the drawing groove 110 after the primer coating and the topcoat coating, the texture groove 120 can better show the wood texture and beauty of the wood floor, and the depth of the texture groove 120 formed after the primer coating and the topcoat coating is less than the depth of the drawing groove 110 on the surface of the base plate 100, so that the texture depth on the surface of the wood floor can be further reduced on the basis of the drawing groove 110, thereby further reducing the problem that the dust and dirt accumulate and are not convenient to clean due to the too deep texture groove 120 in the actual use process of the wood floor, so that the coated wood floor is easier to maintain. Even if the dust and dirt accumulate in the texture groove 120, the dust and dirt in the texture groove 120 can be easily cleaned by the cleaning tools such as the broom and the vacuum cleaner due to the shallow depth of the texture groove 120.
[0053] In some embodiments, in step S1, the depth of the drawing groove 110 is a, 0.05mm≥a≥0.1mm, in step S3, the depth of the texture groove 120 formed after the topcoat coating is b, 0mm>b≥0.05mm. The drawing groove 110 of 0.05mm-0.1mm is formed on the surface of the base plate 100 by the light drawing process, which can facilitate the subsequent paint filling of the primer coating and the topcoat coating to be more uniform. The texture groove 120 of 0mm-0.05mm is formed on the surface of the topcoat layer 300 after the primer coating and the topcoat coating, so that the wood texture and beauty can be shown, and the problem that the dust and dirt accumulate and are not convenient to clean due to the too deep texture groove 120 in the actual use process of the wood floor can be further reduced.
[0054] It can be understood that the depth of the wire drawing groove 110 can be specifically 0.05 mm, or can also be 0.08 mm, 0.1 mm, etc., and the present application does not make specific limitations thereon, as long as 0.05 mm≥a≥0.1 mm. The depth b of the texture groove 120 can be specifically 0.05 mm, or can also be 0.001 mm, and the present application does not make specific limitations thereon, as long as 0 mm>b>0.05 mm.
[0055] In some embodiments, step S1 comprises:
[0056] S1.1: performing a first sanding treatment on the substrate 100;
[0057] S1.2: performing a shallow wire drawing on the substrate 100, with a wire drawing depth of 0.05 mm-0.1 mm;
[0058] S1.3: performing a second sanding treatment on the substrate 100 after the shallow wire drawing.
[0059] By adopting the above method, in step S1, the substrate 100 is first subjected to a surface sanding treatment, so that the surface of the substrate 100 is smoother and more even, which not only facilitates subsequent shallow wire drawing on the surface of the substrate 100 to obtain a wire drawing groove 110 with a depth of 0.05 mm-0.1 mm, but also facilitates subsequent primer coating after the second sanding treatment on the substrate 100 after the shallow wire drawing, so that the subsequent primer coating is more uniform.
[0060] In some embodiments, the multi-pass primer coating process of step S2 comprises:
[0061] S2.1: first-pass primer coating, roll coating a water-based primer on the surface of the substrate 100 to form a first primer layer 210, and curing the first primer layer 210;
[0062] S2.2: second-pass primer coating, roll coating an adhesion primer on the surface of the first primer layer 210 to form a second primer layer 220, and curing the second primer layer 220;
[0063] S2.3: third-pass primer coating, first roll coating a first sanding primer on the surface of the second primer layer 220 using a silicone roller, then roll coating the first sanding primer on the surface of the second primer layer 220 using a brush roller to form a third primer layer 230, and curing and sanding the third primer layer 230;
[0064] S2.4: fourth-pass primer coating, roll coating a wear-resistant primer on the surface of the third primer layer 230 to form a fourth primer layer 240, and curing the fourth primer layer 240;
[0065] S2.5: the fifth pass of primer coating, roll coating a second sanding primer on the surface of the fourth primer layer 240, and then roll coating the second sanding primer on the surface of the fourth primer layer 240 by using a brush roll to form a fifth primer layer 250, and curing and sanding the fifth primer layer 250;
[0066] S2.6: the sixth pass of primer coating, roll coating a third sanding primer on the surface of the fifth primer layer 250 to form a sixth primer layer 260, and curing and sanding the sixth primer layer 260;
[0067] The primer layer 200 includes the first primer layer 210, the second primer layer 220, the third primer layer 230, the fourth primer layer 240, the fifth primer layer 250, and the sixth primer layer 260, which are sequentially stacked on the surface of the substrate 100 from bottom to top.
[0068] In the above method, the water-based primer, the adhesive primer, the first sanding primer, the wear-resistant primer, the second sanding primer, and the third sanding primer are sequentially roll coated on the surface of the substrate 100 by six passes of primer coating. Since the water-based primer has good leveling property and adhesion, the water-based primer can flow into the wire drawing groove 110 and uniformly adhere to the inner wall of the wire drawing groove 110 during roll coating in the first pass of primer coating, which is beneficial to improving the surface flatness of the first primer layer 210. Second, the first sanding primer is used in the third pass of primer coating, the first sanding primer is roll coated on the surface of the second primer layer 220 by using a silica gel roll, and then the sanding primer on the surface of the second primer layer 220 is roll coated by using a brush roll to form the third primer layer 230. The silica gel roll can fully roll coat the first sanding primer to the position of the second primer layer 220 corresponding to the wire drawing groove 110, and the brush roll can roll coat the first sanding primer on the surface of the second primer layer 220 again to uniformly and firmly roll coat the first sanding primer on the second primer layer 220. After roll coating, the second primer layer 220 is cured and sanded, which can provide a flat and strongly adhered substrate for the subsequent fourth pass of primer coating, so that the wear-resistant primer can be more firmly adhered to the third primer layer 230 in the fourth pass of primer coating. In addition, the second sanding primer is roll coated in the fifth pass of primer coating, and the third sanding primer is roll coated in the sixth pass of primer coating, which can facilitate the subsequent topcoat coating, so that the topcoat layer 300 can be more uniformly and firmly adhered to the surface of the primer layer 200.
[0069] It can be understood that the first sanding primer, the second sanding primer, and the third sanding primer described above can use the same type of sanding paint, or different types of sanding paint can be selected, which is not specifically limited in the present application and can be selected according to actual functional requirements.
[0070] It can be understood that in steps S2.3, S2.5 and S2.6, the brush roller is specifically a coconut brush roller, and the coconut brush roller is made of outer coarse fibers of coconut palm after defatting treatment to form the brush, which has good corrosion resistance and softness, can well bring the paint into the wire drawing groove 110, and make the paint coating more uniform and firm. Of course, the brush roller can also be a wool brush roller or a brush roller made of other materials, and the present application does not make specific limitation thereto.
[0071] In some embodiments, in step S2, the water-based primer, the adhesion primer, the first sanding primer, the wear-resistant primer, the second sanding primer and the third sanding primer are all UV primers. The UV primer is a kind of paint that can be quickly cured by ultraviolet irradiation, which can be quickly cured and has good environmental protection, high adhesion and good leveling property, and can be uniformly and firmly attached to the surface of the substrate 100. In addition, in step S2, all the curing processes are UV curing, and the energy value of UV curing is 50 mj, so that the cured UV primer still has certain adhesion to facilitate subsequent primer coating or topcoat coating.
[0072] In some embodiments, in step S2, the coating amount of the first primer, the second primer, the third primer, the fourth primer and the sixth primer is 10g / m 2 -15g / m 2 , and the coating amount of the fifth primer is 15g / m 2 -20g / m 2 , so that the coating of each layer of primer can be more uniform and firm, and the depth of each layer at the wire drawing groove 110 gradually decreases from bottom to top, which is beneficial to reduce the problem of dirt accumulation and inconvenient cleaning of the wood floor due to too deep texture groove 120 in actual use.
[0073] In some embodiments, step S2 further comprises S2.7: roll coating a UV back paint on the surface of the sixth primer layer 260 to form a back paint layer 270, so as to improve the coating adhesion of the topcoat in the subsequent topcoat coating process, and make the subsequent topcoat coating more firm.
[0074] In some embodiments, step S3 comprises:
[0075] S3.1: first topcoat roller coating, first topcoat is roller coated on the surface of the primer layer 200, and then the first topcoat on the surface of the primer layer 200 is roller coated by the brush roller to form the first topcoat layer 310, and the first topcoat layer 310 is cured;
[0076] S3.2: second surface paint roller coating, the second surface paint is rolled on the surface of the first surface paint layer 310 to form a second surface paint layer 320, and the second surface paint layer 320 is cured.
[0077] By setting two surface paint roller coating processes, the first surface paint coating process uses a brush roller to perform secondary roller coating of the first surface paint on the surface of the primer layer 200, so that the first surface paint can be uniformly and firmly attached to the surface of the primer layer 200, and the second process does not use a brush roller for secondary roller coating, so that the surface flatness and smoothness of the second surface paint layer 320 can be ensured, which is beneficial to improve the aesthetics of the wood floor.
[0078] It can be understood that in some embodiments, the brush roller in step S3.1 can be a wool brush roller. The wool brush roller has fine and soft peaks, which can well bring the surface paint to the positions corresponding to the wire drawing grooves 110 of the primer layer 200, and make the surface paint coating more uniform and firm. Of course, the brush roller in step S3.1 can also use a coconut brown brush roller or a brush roller made of other materials, which is not limited in the present application.
[0079] In some embodiments, in step S3.1, the first surface paint is a UV surface paint, and the curing process used is UV curing, wherein the UV curing energy is 80mj-100mj;
[0080] In step S3.2, the second surface paint is a UV surface paint, and the curing process used is UV curing, wherein the UV curing energy is 280mj-300mj.
[0081] In the above method, the first primer and the second primer both use UV surface paint, which is a coating that can be quickly cured by ultraviolet irradiation. The UV surface paint can be quickly cured, has good environmental protection, high adhesion, and good leveling, and can be uniformly and firmly attached to the surface of the primer layer 200. In addition, all the curing processes in step S3 use UV curing, wherein the UV curing energy of the first surface paint layer 310 is 80mj-100mj, so that the cured UV surface paint still has certain adhesion to facilitate the subsequent coating of the second surface paint, and the UV curing energy of the second surface paint layer 320 is 280mj-300mj, which is greatly improved compared to the curing energy of the first surface paint. Thus, the second surface paint layer 320 can be completely cured, which is beneficial to improve the surface structure strength of the wood floor and avoid scratches or other undesirable phenomena on the surface of the wood floor during actual use.
[0082] In some embodiments, the coating amount of the surface paint in the first surface paint roller coating and the second surface paint roller coating is 5g / m 2 -8g / m 2The face paint layer 300 is relatively thin, which is beneficial to better display the wood texture and further improve the aesthetics of the wood floor.

[0099] The following table is the wood floor physical and chemical performance test results obtained by using the wood floor surface coating method described above:
[0100] Test item Unit Standard specified value Test result Individual result Paint film adhesion Grade ≤3 2 Pass Paint film hardness — ≥ H, not scratched H, not scratched Pass Surface stain resistance Grade ≥ Grade 4 Grade 5 Pass
[0101] As can be seen from the above, the wood floor obtained by using the wood floor surface coating method has good paint film adhesion, paint film hardness and surface stain resistance. The surface of the substrate 100 is treated by using a shallow wire drawing process, and the substrate 100 is coated with a primer by using a multi-pass primer coating process. At least one primer coating process uses a silica gel roller for primer roller coating. The silica gel roller is softer than a conventional paint roller, so that the primer can be fully filled into the wire drawing groove 110. After the primer roller coating, the primer on the surface of the substrate 100 is secondarily coated by using a brush roller, so that the primer on the surface of the substrate 100 can be brought into the wire drawing groove 110 by the brush roller and the primer on the surface of the substrate 100 can be reinforced, so that the primer is more uniformly filled. In addition, after the primer coating and topcoat coating, the texture groove 120 can be formed on the surface of the topcoat layer 300 corresponding to the position of the wire drawing groove 110. The depth of the texture groove 120 is less than the depth of the wire drawing groove 110 on the surface of the substrate 100, so that the texture groove 120 can better show the wood texture and beauty of the wood floor. In addition, the problem of dust and dirt accumulation due to the too deep texture groove 120 during actual use of the wood floor can be further reduced, so that the coated wood floor is easier to maintain.
[0102] The embodiments of the present application are described in detail above with reference to the drawings, but the present application is not limited to the above-described embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present application. In addition, the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.
