Problems solved by technology

[0006] First, the formaldehyde purification performance of ecological wood described in the CN202039549U patent technology is based on the physical structure of an inner cavity that can be filled with activated carbon, and a single formaldehyde adsorption is achieved through the physical adsorption of activated carbon, which cannot achieve formaldehyde decomposition and purification. shortcoming
[0007] Second, the negative ions, antibacterial and antifungal properties of ecological wood described in CN2707884Y, CN2763394Y, and CN1896438A patent technology are also based on the physical structure, glued or coated with a layer of coating layer impregnated with anion powder or antibacterial and antifungal agent. Layer molecular diffusion, because the product must have a dense wear-resistant layer to meet the wear-resistant requirements of wood flooring products, so it has shielding properties for the coating layer with ecological effects. At the same time, as mentioned above, between layers There are free formaldehyde and free phenol pollution problems in most of the adhesives, which run counter to the principle of maintaining ecological health
[0008] Third, the negative ions, antibacterial and antifungal properties of ecological wood described in CN102558715A and CN202131269U patent technologies are based on adding mixed powders of minerals and mineral oxides that can generate negative ions and composite antibacterial and antifungal agents to wood-plastic composite materials. Extrude, cool and shape it to wrap it in it, and also stay in the compounding of the physical structure composition, because the continuous polymer matrix in the wood-plastic structure makes the gas, molecules, visible light absorption, etc. in the product application affect the ecological performance There are slow diffusion or free breathing in the channel, and there are also ecological shielding defects; on the other hand, the wood-plastic materials based on thermoplastic polymers cause chlorine gas to be released due to high-temperature hot-melt mismatch, aging, degradation, and chromatography Scattering, affecting human health and environmental pollution, and plant fiber gelatinization, affecting the imitation wood grain texture and imitation wood feeling, which limits the application range of the product
