Description

Technical Field

[0001] The present invention relates to the technical field of furniture panels, in particular to an antibacterial and antifouling furniture panel and a manufacturing process thereof. Background Art

[0002] Currently, with the upgrading of indoor environmental health standards and consumers' increasing demands for home quality, the market demand for antibacterial and antifouling furniture panels continues to rise. However, existing products still face multiple bottlenecks in terms of technical implementation:

[0003] Traditional processes for constructing antimicrobial systems for substrates often rely on surface coating or simple impregnation, resulting in uneven distribution of antimicrobial components and weak bonding. Conventional antimicrobial layers are susceptible to component loss due to physical friction or humidity fluctuations, resulting in insufficient antimicrobial durability and an inability to effectively inhibit microbial regeneration. Regarding structural mechanical properties, conventional honeycomb panels, limited by the frame connection method and filler material properties, often suffer from uneven stress distribution and weak edge bonding strength. They are prone to deformation and warping during long-term load-bearing use, impacting the structural stability and service life of furniture. Regarding surface functional coatings, while existing technologies can achieve basic antifouling effects, they struggle to balance coating hardness and hydrophobicity. Most products experience significant degradation in surface protection after frequent friction or contact with complex contaminants, failing to meet the penetration resistance requirements of daily use. Regarding environmental performance, some panels, due to limitations in adhesive selection and process control, still release harmful substances during use. Especially in confined spaces, the slow release of chemical residues poses a potential threat to indoor air quality. Therefore, we propose an antimicrobial and antifouling furniture panel and its production process. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the existing defects and provide an antibacterial and antifouling furniture board and its production process. Through innovative material system and structural design, the synergistic improvement of antibacterial long-term effect, mechanical stability, surface protection and environmental friendliness can be achieved, which can effectively solve the problems in the background technology.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: an antibacterial and antifouling furniture panel, comprising a base plate, the upper side of the base plate being bonded to a supporting frame by PUR hot-melt adhesive, the supporting frame being formed by bonding and cutting evenly distributed hexagonal frames, the lower end of the inside of the hexagonal frame being filled with antibacterial sol, the upper side of the antibacterial sol being bonded with sound-absorbing cotton, the edge of the supporting frame being filled with reinforced foam glue, the upper side of the supporting frame being bonded to an antifouling top plate by two-component epoxy glue, the side of the reinforced foam glue being bonded with four corresponding reinforcing edge strips, the reinforcing edge strips being bonded between the base plate and the antifouling top plate, and effective antibacterial effect can be achieved by setting the antibacterial sol.

[0006] Furthermore, the antibacterial sol is a nano silver-titanium dioxide composite sol, the silver content of the nano silver-titanium dioxide composite sol is ≥6000ppm, the antibacterial rate is ≥99.9%, and the sound-absorbing cotton is melamine foam with a density of 8-12kg / m 3 , NRC ≥ 0.8, sound insulation is achieved by setting sound-absorbing cotton.

[0007] Furthermore, evenly distributed strip grooves are provided on the upper side of the base plate, and stainless steel reinforcement ribs are fixed inside the strip grooves. The diameter of the stainless steel reinforcement ribs is 2 mm, and the tensile strength is ≥520 MPa. The depth of the strip grooves is 1 / 3 of the thickness of the base plate. The strength of the base plate is improved by providing stainless steel reinforcement ribs.

[0008] Furthermore, the sides of the bottom plate, anti-fouling top plate and four reinforcing edge strips are coated with a primer, the surface of the primer is coated with a surface coating, the primer is a nano-silica composite coating with a hardness ≥9H, and the surface coating is a super-hydrophobic nano-coating containing fluorocarbon resin with a contact angle ≥110°, by setting the primer and the surface coating.

[0009] Furthermore, nano-TiO2 photocatalytic particles are added to the surface coating at a concentration of 3%-5%, and the formaldehyde purification efficiency under ultraviolet irradiation is ≥98.9%.

[0010] A process for producing an antibacterial and antifouling furniture board comprises the following steps:

[0011] S1 Base plate pretreatment: Mill the base plate to form strip grooves, embed stainless steel reinforcement ribs and fix them with cyanogen gel;

[0012] S2 honeycomb core layer assembly: The hexagonal wooden frames are glued together with epoxy resin to form a support frame. The diameter of the epoxy resin glue dots is ≤1mm.

[0013] S3 functional filling: vacuum impregnate the bottom of the hexagonal frame with antibacterial sol, the vacuum degree of vacuum impregnation is -0.08MPa, the penetration time is ≥2 hours, the penetration rate is ≥95%, and then fill the top with sound-absorbing cotton;

[0014] S4 edge reinforcement: Cut the edge of the support frame, inject polyurethane foam glue, pre-coat the reinforcement edge strip with PUR glue and bond it between the bottom plate and the anti-fouling top plate, pressurize and cure at a pressure of 0.5 MPa for 30 minutes;

[0015] S5 surface lamination: The anti-fouling top plate is laminated with the support frame by hot pressing with PUR hot melt adhesive. The coating amount of PUR hot melt adhesive is 400ml / m 2 , hot pressing composite temperature 150 ℃, hot pressing composite pressure 0.8MPa, holding time 30 seconds;

[0016] S6 coating treatment: Apply primer and surface coating on the bottom plate, anti-fouling top plate and the side of the reinforced edge strip in sequence. The curing temperature of the primer is 100℃ and the curing temperature of the surface coating is 150℃.

[0017] Furthermore, in step S3, the vacuum impregnation penetration time of the antibacterial sol is ≥2 hours, and the moisture content after curing is ≤7%.

[0018] Furthermore, in step S6, the super-hydrophobic nano-coating is applied by a chemical vapor deposition (CVD) process, with a film thickness of 50 μm and a surface roughness of Ra=0.5-2 μm.

[0019] Furthermore, in step S4, the joints between the reinforcing edge strips and the bottom plate and the anti-fouling top plate are interference fit, and the interference fit amount is 0.05-0.1 mm.

[0020] Furthermore, after hot pressing and laminating in step S5, the edges of the plate are chamfered at a chamfer angle of 45°.

[0021] Compared with the prior art, the beneficial effects of the present invention are: the antibacterial and antifouling furniture board and its production process have the following advantages:

[0022] 1. A nanosilver-titanium dioxide composite sol (silver content ≥ 6000ppm) is infiltrated into the base of the hexagonal frame through a vacuum impregnation process, achieving a three-dimensional uniform distribution of the antimicrobial components. Combined with a moisture content of ≤ 7% after curing, this ensures the long-term stability of the antimicrobial efficacy (antibacterial rate ≥ 99.9%). The synergistic design of the honeycomb support frame and polyurethane foam filling increases the compressive strength of the board by over 40%. The 0.05-0.1mm interference fit of the edge reinforcement strips further suppresses stress concentration, ensuring the structural integrity of the furniture under long-term load-bearing conditions.

[0023] 2. A dual-coating system consisting of a nano-silica composite base layer (hardness ≥ 9H) and a fluorocarbon resin super-hydrophobic surface layer (contact angle ≥ 110°) is used. A 50μm rough surface (Ra = 0.5-2μm) is formed through a CVD process, achieving both scratch resistance and self-cleaning properties. The surface layer is infused with 3%-5% nano-TiO2 photocatalytic particles, which can efficiently decompose formaldehyde under ultraviolet light (purification efficiency ≥ 98.9%), simultaneously addressing both surface and indoor air pollution issues.

[0024] 3. The porous structure formed by melamine sound-absorbing cotton (NRC ≥ 0.8) and honeycomb frame realizes the synergistic optimization of noise reduction and lightweight (density reduction of 25%-30%). PUR hot melt adhesive (VOC emission ≤ 0.1mg / m 3 ) and solvent-free coating technology, so that the formaldehyde emission of the board is ≤0.02mg / m 3, far exceeding the E0 environmental protection standard and meeting the healthy use needs of confined spaces;

[0025] 4. A -0.08MPa vacuum impregnation and 150°C gradient curing process ensures efficient penetration of functional materials and interfacial bonding strength. A 0.8MPa hot-pressing composite process creates a dense interface between the anti-fouling top plate and the core layer, with a peel strength of ≥8N / mm. Chemical vapor deposition film formation technology achieves a dense, nanoscale coverage of the super-hydrophobic coating, with a wear resistance of ≥5000 times (ASTM D4060 standard), extending the service life by 3-5 times.
