Description

Technical Field

[0001] The present invention relates to the technical field of gypsum boards, and specifically to a bactericidal and antiviral gypsum board. Background Art

[0002] Most of the gypsum boards on the market at present do not have the function of self-cleaning, and most of the boards with bactericidal functions are achieved by adding metal materials inside the boards. The antiviral effect on the surface of the boards is not obvious and the price is relatively expensive. With the improvement of living standards, more and more public places, especially outdoor public places, begin to pay attention to beauty and beautification. Some places will lay boards for beautification. For example, in toilets. However, it is still inevitable to have dust deposition. Especially after getting wet, the surface will show a "dirty face" phenomenon. Each cleaning is time-consuming and laborious, and static electricity is likely to accumulate after entering the dry season, often causing people to be defenseless against static electricity damage. It has the following defects: 1. Prone to dirt and static electricity accumulation; 2. Frequent cleaning invisibly damages the surface and shortens the service life of the board; 3. The price of antiviral boards is expensive and the antiviral effect on the surface is not good; 4. Prone to static electricity damage. Summary of the Invention

[0003] In view of the deficiencies of the prior art, the present invention provides a bactericidal and antiviral gypsum board, which solves the problems raised in the above background art.

[0004] To solve the above technical problems, according to one aspect of the present invention, more specifically, a bactericidal and antiviral gypsum board includes a self-cleaning board. The self-cleaning board sequentially includes a stone-plastic substrate layer, a pattern primer layer, an antiviral UV-curable coating layer, and a self-cleaning topcoat layer from bottom to top. The thickness of the self-cleaning board is 0.2 - 0.6 cm, and the thickness of the stone-plastic substrate layer is 0.1 - 0.4 cm; The pattern primer layer and the self-cleaning topcoat layer are water-based UV-curable coatings. The stone-plastic substrate layer contains 60 - 80% of PVC. The pattern primer layer contains silicone resin, diatomaceous earth, and phosphorylated epoxy resin. The phosphorylated epoxy resin is formed by phosphoric acid and epoxy resin at 105 - 108 °C. The self-cleaning topcoat layer is a water-based fluorocarbon-type nano-coating, and the water-based fluorocarbon-type nano-coating contains organosilicon-modified fluororesin particles, as well as nano-titanium oxide particles, nano-silicon oxide particles, and titanium phosphate particles.

[0005] Furthermore, the antiviral UV-curable coating layer contains graphene particles, super-nano titanium dioxide particles, antimony trioxide particles, zinc borate particles, carbon steel fiber particles, microcrystalline wax particles, carbon black powder, and kaolin. The particle size of the super-nano titanium dioxide particles is 1 - 20 nm.

[0006] Furthermore, the antiviral photocurable coating layer contains alkyl phosphate ethylene glycol amine salt.

[0007] Furthermore, an installation groove is provided at the edge of the self-cleaning plate. A connecting sleeve is arranged inside the installation groove. The connecting sleeve is adhesively bonded inside the installation groove through glue. The connecting sleeve includes a connecting body and a limiting head. Strip-shaped grooves are respectively provided on the left and right surface portions of the connecting body.

[0008] Furthermore, two connecting holes are provided inside the connecting sleeve. Fixed barbs are respectively provided on the inner walls of the two connecting holes. A right-angle fixing member and a straight fixing member are respectively placed in the two connecting holes. Barbs are provided at both ends of the right-angle fixing member and the straight fixing member. The barbs are in contact with the fixed barbs. Quick-drying glue is filled in the connecting holes. The right-angle fixing member and the straight fixing member are fixedly connected to the connecting sleeve through the quick-drying glue.

[0009] Furthermore, the other end of the right-angle fixing member penetrates into the wall hole and is connected to the wall through glue. The other end of the straight fixing member penetrates into the connecting sleeve inside another self-cleaning plate. The other end of the right-angle fixing member connected to another self-cleaning plate penetrates into the same wall hole.

[0010] The beneficial effects of a bactericidal and antiviral gypsum board of the present invention are as follows: (1). By rolling functional coatings such as self-cleaning coatings and antiviral coatings on the board, and supplemented by the novel characteristics of the board, the board achieves self-cleaning, antiviral properties and an affordable price. Since it contains ultra-nanoscale conductive materials, the board has the performance of preventing static electricity generation, and the hydrophobicity of the board surface is increased, making it not easy to adsorb dust. In this way, it is not necessary to consume a large amount of manpower and material resources for cleaning.

[0011] (2). By installing a connecting sleeve, a right-angle fixing member and a straight fixing member at the edge of the board, when the board needs to be installed on the wall, only by inserting the two ends of the right-angle fixing member into the wall and the connecting sleeve respectively, the board can be fixed to the wall, and multiple boards can be connected in series by using the straight fixing member, which can greatly improve the overall firmness performance of the board.

Through the characteristics of the self-cleaning topcoat layer 104 and the antiviral photocurable coating layer 103, the advantages of self-cleaning, antiviral, and affordable price of the board can be achieved. And because it contains ultra-nano-scale conductive materials, the board has the performance of preventing static electricity generation, and the hydrophobicity of the board surface is increased, and it is not easy to adsorb dust. In this way, it is not necessary to consume a large amount of manpower and material resources for cleaning.

[0017] In this embodiment, the antiviral photocurable coating layer 103 contains graphene particles, ultra-nano-scale titanium dioxide particles, antimony trioxide particles, zinc borate particles, carbon steel fiber particles, microcrystalline wax particles, carbon black powder, and kaolin. The particle size of the ultra-nano-scale titanium dioxide particles is 1 - 20 nm.

[0018] In this embodiment, the antiviral photocurable coating layer 103 contains alkyl phosphate ethylene glycol amine salt.

[0019] In this embodiment, an installation groove 2 is provided at the edge of the self-cleaning plate 1, and a connecting sleeve 6 is arranged inside the installation groove 2. The connecting sleeve 6 is adhesively bonded inside the installation groove 2 with glue. The connecting sleeve 6 includes a connecting body 601 and a limiting head 602. Strip-shaped grooves 9 are formed on both the left and right surface sides of the connecting body 601. After inserting the connecting sleeve 6 into the installation groove 2 and applying glue, the strip-shaped grooves 9 can be used to increase the contact area with the glue, so that the connecting sleeve 6 and the installation groove 2 can be more firmly fixed.

[0020] In this embodiment, two connecting holes 5 are provided inside the connecting sleeve 6, and fixing barbs 8 are arranged on the inner walls of the two connecting holes 5. A right-angle fixing member 3 and a straight fixing member 4 are respectively placed in the two connecting holes 5.

After inserting the right-angle fixing member 3 into the wall and applying glue, then insert the other end of the right-angle fixing member 3 into the connecting sleeve 6. And a straight fixing member 4 also needs to be installed inside the connecting sleeve 6. In this way, when installing other self-cleaning plates 1, only align the connecting sleeve 6 on other self-cleaning plates 1 with the straight fixing member 4 and insert them.
