Description

Technical Field

[0001] The present application relates to the field of floor technology, and in particular to a solid wood composite floor with yellowing UV-resistant coating. Background Art

[0002] Since wood is corroded by ultraviolet rays, visible light, oxygen, water, chemicals and microorganisms, when making solid wood composite flooring, it is necessary to ensure that the paint finish of the solid wood composite flooring has a shielding and protective effect to extend the service life of the wood.

[0003] At present, wood color and light color have become the popular style trend of home decoration. When wood color and light color solid wood composite floor are used as interior decoration materials, they are more susceptible to environmental factors and deterioration, especially under the influence of ultraviolet light, the solid wood composite floor will turn yellow, affecting the durability and experience of wood color and light color solid wood composite floor. For wood color and light color solid wood composite floor, ultraviolet light can easily penetrate general transparent UV coating, especially for transparent UV coating, there is no protective film with light shielding function or added pigments and fillers to prevent light aging, which makes wood color and light color solid wood composite floor more likely to change color under the action of sunlight, causing wood color and light color solid wood composite floor to turn yellow.

[0004] Therefore, preventing the original wood color and light-colored solid wood composite flooring from turning yellow due to light exposure has become a top priority. Summary of the invention

[0021] Reference Figure 1 , an embodiment of the present application is proposed, and the solid wood composite floor with yellowing-resistant UV coating described in this embodiment includes a substrate 10 and a yellowing-resistant UV water-based primer 20, a UV transparent adhesion primer 30, a UV hardening primer 40, a UV sanding primer 1 50, a UV sanding primer 2 60, a transparent matte topcoat 1 70 and a transparent matte topcoat 2 80 which are sequentially arranged on the front side of the substrate 10.

[0022] In the present application, the yellowing-resistant UV water-based primer 20 is colored by roller coating, and the yellowing-resistant UV water-based primer 20 is formed by mixing the yellowing-resistant primer and the water-based primer. The yellowing-resistant UV water-based primer 20 should determine the mixing ratio of the yellowing-resistant primer and the water-based primer according to their components and properties, so as to ensure that the yellowing-resistant primer and the water-based primer can penetrate the yellowing-resistant UV water-based primer 20 through the base capillaries to a certain depth inside the substrate 10 and then reinforce the base, and have good adhesion to the wood;

[0023] Therefore, the present application uses the yellowing-resistant UV water-based primer 20 as the first primer of the solid wood composite floor to protect the substrate 10 from ultraviolet erosion, thereby improving the yellowing resistance of the solid wood composite floor;

[0024] Furthermore, the five primers of the solid wood composite floor all use UV curing primer, which can resist ultraviolet rays to a certain extent, reduce the erosion of ultraviolet rays on the solid wood composite floor, and improve the yellowing resistance of the solid wood composite floor;

[0025] Furthermore, the solid wood composite floor described in the present application uses two coats of matte topcoat. The matte topcoat has a relatively low glossiness and a stronger ability to absorb ultraviolet rays, thereby reducing the amount of ultraviolet rays that penetrate the matte topcoat and irradiate the primer and substrate 10, which is beneficial to improving the yellowing resistance of the solid wood composite floor.

[0026] In this embodiment, the paint finishing process of the solid wood composite floor is: plain board sanding → yellowing-resistant UV water-based primer 20 → adhesion primer → hardening primer → wear-resistant primer → sanding primer 1 → sanding primer 2 → rolling back paint → matte topcoat 1 → matte topcoat 2.

[0027] Preferably, it further comprises an ultraviolet reflecting paint layer 90 disposed between the UV sanding primer 2 60 and the transparent matte topcoat 1 70, wherein the ultraviolet reflecting paint layer 90 is used for reflecting ultraviolet rays irradiated thereto.

[0028] In the present application, two matte topcoat layers are used to absorb ultraviolet rays, and the ultraviolet rays that are not absorbed will penetrate the two matte topcoat layers and then reach the primer layer. By setting an ultraviolet reflecting paint layer 90 between the UV sanding primer 2 60 and the transparent matte topcoat 1 70, the ultraviolet reflecting paint layer 90 can reflect the ultraviolet rays irradiated thereto, thereby reducing the ultraviolet rays incident on the primer layer, which is beneficial to reducing the ultraviolet rays irradiated to the substrate 10 and improving the yellowing resistance of the solid wood composite floor.

[0029] Wherein, the ultraviolet reflective paint layer 90 is mica paint.

[0030] Mica paint contains mica flakes. Mica is a flaky crystal that can absorb ultraviolet rays, reflect and scatter ultraviolet rays, and can also transmit visible light. When sunlight irradiates, the mica flakes reduce the ultraviolet rays that irradiate the primer and the substrate 10, which is beneficial to improving the yellowing resistance of the solid wood composite floor. The mica flakes can also refract visible light to display the color of the primer and the substrate 10, thereby improving the aesthetics.

[0031] Furthermore, the UV reflective paint layer 90 is formed by stacking several layers of mica paint, and the several layers of mica paint can be one layer, two layers or multiple layers of mica paint. When the UV reflective paint layer 90 is stacked with two or more layers of mica paint, the mica flakes in the mica paint can be distributed at different positions of the UV reflective paint layer 90 and overlap with each other, which is beneficial to improving the absorption, reflection and scattering effects of the UV reflective paint layer 90 on ultraviolet rays.

[0032] Preferably, a moisture-proof paint layer is further provided on the back side of the substrate 10 .

[0033] By providing a moisture-proof paint layer on the back side of the substrate 10, the moisture-proof paint layer can prevent the back side of the substrate 10 from being deformed due to the entry of water vapor.

[0034] Preferably, in this embodiment, the transparent matte topcoat layer 1 70 is a matte wear-resistant topcoat layer, and the transparent matte topcoat layer 2 80 is a matte scratch-resistant topcoat layer. The matte wear-resistant topcoat layer can improve the wear resistance of the paint finish on the surface of the solid wood composite floor, and the matte scratch-resistant topcoat layer can improve the scratch resistance of the paint finish on the surface of the solid wood composite floor, thereby improving the wear resistance and scratch resistance of the surface of the solid wood composite floor, improving the wear resistance and scratch resistance of the paint finish on the surface of the solid wood composite floor, and helping to extend the service life.

[0035] Of course, the present invention is not limited to the above-mentioned embodiments, and technicians familiar with the field may make equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications and substitutions are all included in the scope defined by the claims of this application.
