Description

Technical Field

[0001] This invention belongs to the field of building materials technology, and relates to wall panels, and more particularly to an antiviral firewall panel with impact resistance and its manufacturing method. Background Technology

[0002] As living standards continue to improve, consumers have higher and higher requirements for housing. Terms such as antibacterial and antiviral are constantly appearing in consumers' field of vision, and antibacterial and antiviral have become a new development trend.

[0003] A search revealed two types of antiviral impregnated paper disclosed in patents CN115928503A and CN218812892U. These decorative papers can be used for surface finishing of facade materials, thereby giving the material surface antibacterial and antiviral effects. CN220644947U also discloses an antiviral wall panel that can be easily installed. These patents enable surface decoration on flat surfaces and allow for easy installation. However, facade materials, in addition to antibacterial and antiviral properties, also need certain decorative properties. For example, while CN220644947U achieves antiviral functionality, it does not address the impact resistance issue.

[0004] Existing wall panels still have the following shortcomings: (1) They generally lack effective impact-resistant buffer structures, which can easily cause human injury in collision scenarios; (2) The surface decorative textures are often relatively simple, making it difficult to meet personalized needs; (3) It is difficult to simultaneously achieve multiple functions such as antibacterial / antiviral properties, diverse decorative textures, impact resistance, and decoration. This invention integrates antiviral properties, 3D decorative textures, and a buffer layer simultaneously through a five-layer composite structure for the first time, effectively mitigating impact phenomena. Summary of the Invention

[0005] In view of the problems existing in the prior art, the purpose of this invention is to disclose an antiviral wall panel with obvious surface texture and impact resistance. Through a specific structure, it achieves surface antibacterial and antiviral properties while taking into account impact resistance and aesthetics.

[0006] Technical solution

[0007] An antiviral firewall with impact resistance comprises an antiviral layer, a decorative layer, a textured substrate layer, an adhesive layer, and an impact-absorbing layer stacked sequentially. The antiviral layer is a UV coating layer containing antiviral additives, which are mixed in the UV coating at a mass ratio of 1:20 to 1:25. The decorative layer is a digitally printed layer. The textured substrate layer is an ABS, PMMA, or SPC material sheet formed by extrusion molding, with its front side forming a regular or irregular 3D texture structure during the molding process. The adhesive layer is a room-temperature curing PUR adhesive layer. The impact-absorbing layer is a foamed material layer, which is a polyolefin elastomer foam (EPO) or polypropylene foam (EPP) with added flame retardants, and the amount of flame retardant added achieves a GB8624-2012 B1 flame retardant rating for the foamed material layer.

[0008] In a preferred embodiment of the present invention, the antiviral additive in the antiviral layer includes any one or a combination of anionic organic compounds, silver-loaded zeolite, and natural plant essential oils. Its effective components mainly achieve the effect of rapid virus inactivation by destroying the outer membrane of the enveloped virus.

[0009] Furthermore, the anionic organic compound is polyvinyl sulfonic acid, chitosan quaternary ammonium salt, etc.

[0010] Furthermore, the natural plant essential oil is an essential oil emulsion obtained by processes such as shearing, emulsification, and wall-forming of one or more natural plant essential oils such as sandalwood, rosewood, and mugwort.

[0011] In a preferred embodiment of the present invention, the amount of the antiviral additive added to the surface of the wall panel in the antiviral layer is 0.64 g / m². 2 ~1.20g / m 2 .

[0012] In a preferred embodiment of the present invention, the decorative layer is applied directly to the 3D textured surface of the textured substrate layer using digital printing technology.

[0013] In a preferred embodiment of the present invention, the textured substrate layer is combined with the decorative layer to achieve different texture effects such as stone texture, fabric texture, leather texture, and mirror finish. The textured substrate layer is one of the following materials: ABS, PMMA, SPC, etc.

[0014] In a preferred embodiment of the present invention, the density of the foamed material in the impact-absorbing layer is 0.03-0.2 g / cm³. 3 0.1g / cm 3 The foaming ratio is between 10 and 30 times. Generally speaking, the lower the expansion ratio (higher density), the better the rigid support of the material; the higher the expansion ratio (lower density), the better the softness, cushioning, and energy absorption of the material. The conversion relationship between density and expansion ratio is density ≈ resin density / expansion ratio.

[0015] A second objective of this invention is to disclose a method for manufacturing the antiviral firewall board with impact resistance.

[0016] A method for manufacturing an antivirus firewall panel with impact resistance includes the following steps:

[0017] S1. Select a 2-5mm thick extruded substrate (ABS, PMMA, SPC, etc.) as the texture substrate layer, and perform a roughening and sanding treatment on its back side;

[0018] S2. Apply PUR adhesive roller to the back of the textured substrate layer, with an adhesive application rate of 56~60g / m². 2 Temperature of the control roller / spreading roller: 160℃; Temperature of the coating roller: 110℃.

[0019] S3. Apply EPO or EPP foam material to the back of the textured substrate layer. The thickness of the foam material is 3-5 mm, the expansion ratio is 15-30 times, and the density is 0.03-0.2 g / cm³. 3 Then allow it to cure for 5-7 days, adjusting the temperature and humidity according to the environment;

[0020] S4. 3D digitally print patterns such as stone texture, fabric texture, leather texture, mirror finish, etc. on the front side of the textured substrate layer to form a decorative layer, and then dry and cure it;

[0021] S5. Roller-coating antiviral UV coating onto the decorative layer surface, with a coating amount of 8~12g / m². 2 The coating is applied in two coats and then cured with UV light to form an antiviral layer. The antiviral UV coating is made by mixing antiviral additives and UV coatings at a mass ratio of 1:20 to 1:25.

[0022] In a preferred embodiment of the present invention, in S1, the sanding depth is 0.15~0.25mm.

[0023] In a preferred embodiment of the present invention, in S3, the ambient temperature is 15~30℃ and the relative humidity is 40~70%.

[0024] In a preferred embodiment of the present invention, in S5, the total coating weight of the antiviral UV coating is 16-24 g / m². 2 .

[0025] Beneficial effects

[0026] The antiviral fireproof wall panel disclosed in this invention features a surface antiviral layer that effectively inhibits the survival and spread of viruses, improving hygiene and safety. Combined with a digitally printed decorative layer and the 3D texture inherent in the substrate, it allows for diverse and personalized surface textures, enhancing the decorative effect. A dedicated impact-absorbing foam layer effectively absorbs collision energy, reducing the risk of injury from collisions between the human body and the wall. The addition of flame retardants to the impact-absorbing layer gives the wall panel excellent flame-retardant properties, improving building safety. Therefore, this impact-resistant antiviral fireproof wall panel is particularly suitable for public places with high hygiene, safety, and protection requirements, such as hospitals, schools, and nursing homes.
