[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] See also Figure 1-Figure 3 The utility model provides a technical solution: a polyurethane anti-corrosion coating structure on the surface of furniture, including a first coating 1, a second coating 2 and a third coating 3, the first coating 1 is attached to the surface of the furniture, the second coating 2 is attached to the second coating 2, the second coating 2 is attached to the third coating 3, the first coating 1 is a polylactic acid anti-corrosion coating, the second coating 2 is an acrylic reflective coating, and the third coating 3 is an epoxy resin coating.

[0034] The material design of the first coating 1 makes the furniture have good anti-corrosion performance, and the material design of the second coating 2 forms a highly reflective film layer on the surface of the first coating 1, which can effectively reflect light back, thereby preventing ultraviolet rays from irradiating the first coating 1 and the furniture, preventing the first coating 1 and the furniture from aging under ultraviolet rays, and increasing the service life of the furniture;

[0035] The material design of the third coating 3 has good strength and wear resistance, which can prevent the first coating 1 and the second coating 2 from being damaged by collision, thereby increasing the service life of the first coating 1 and the second coating 2.

[0036] The first coating 1 is provided with a first groove 4, and the second coating 2 extends upward to form a first protrusion 5, the first protrusion 5 matches the first groove 4, the first grooves 4 are evenly distributed on the first coating 1, and the cross section of the first groove 4 is circular;

[0037] The second coating 2 on the top surface of the first protrusion 5 is recessed downward to form a second groove 6 , and the third coating 3 vertically extends upward to form a second protrusion 7 , and the second protrusion 7 matches the second groove 6 .

[0038] When preparing the coating, a first coating 1 can be formed on the surface of the furniture by spraying or the like, and then a plurality of first grooves 4 can be pressed out on the first coating 1 by a tool, and then the second coating 2 can be sprayed on the surface of the first coating 1. When the second coating 2 is sprayed, the first coating 1 is not flat due to the existence of the first groove 4, so the second coating 2 located at the first groove 4 will be sunken downward to form a first protrusion 5, and because the thickness of the second coating 2 and the first protrusion 5 is equal to the groove height of the first groove 4, a first groove 4 will be formed between the first protrusion 5 and the second coating 2 on both sides.

[0039] Finally, the third coating 3 is sprayed on the second coating 2. In this process, since the thickness of the third coating 3 is greater than the groove height of the second groove 6, the first groove 4 will be filled first, that is, the second protrusion 7 is combined with the first groove 4, and finally the third coating 3 is attached to the surface of the second coating 2.

[0040] After the coating is prepared, the first coating 1 and the second coating 2 are combined, and the snap connection formed by the first groove 4 and the first protrusion 5 can further increase the bonding area, thereby improving the bonding strength between the first coating 1 and the second coating 2;

[0041] The second coating 2 and the third coating 3 are combined, and the snap connection formed by the second groove 6 and the second protrusion 7 can further increase the bonding area, thereby improving the bonding strength between the second coating 2 and the third coating 3, so that there is no need to use external connectors to improve the bonding strength between the coatings.

[0042] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
