Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of veneer, specifically relates to a hydrophobic antibacterial three amine veneer. BACKGROUND

[0002] With the continuous improvement of people's health consciousness, the safety and health requirement of living environment is also rising, not only the furniture board needs to have the environmental protection of low formaldehyde, but also needs to meet the antibacterial and mildew resistance performance, especially in the south where there is long time plum rain weather and high air humidity, the veneer of furniture such as hanging cabinet and dining cabinet is in the state of contacting and infiltrating with water vapor for a long time, and even forms suspended water droplets on the surface of the veneer in the back-to-south season, so the antibacterial and mildew resistance performance of the veneer is particularly concerned by the users in the south.

[0003] However, most of the commercially available antibacterial boards are coated with a layer of antibacterial paint on the surface of the board, thereby forming a surface antibacterial effect, but the antibacterial coating located at the outermost side of the board is easily damaged in daily use, and it is difficult to maintain stable and effective antibacterial performance for a long time.

[0004] In order to solve the problem that the antibacterial coating located at the outermost side of the board is easily damaged, the patent document with the application number CN202320091814.5 discloses a new antibacterial veneer, which comprises a veneer, the veneer comprises a scratch-resistant and anti-static film, an antibacterial coating, a decorative layer, a fireproof high-density board and an osb board, the scratch-resistant and anti-static film is located outside the antibacterial coating, the antibacterial coating is located outside the decorative layer, the decorative layer is located outside the fireproof high-density board, and the fireproof high-density board is located outside the osb board.

[0005] The above-mentioned prior art coats an antibacterial coating on the surface of the substrate, and then covers a scratch-resistant and anti-static film protective layer, so that the prepared veneer has scratch-resistant and antibacterial properties, and the antibacterial effective period can be prolonged, but the prior art is not suitable for melamine veneer.

In the process of developing long-acting antibacterial melamine veneer, the inventors found that the above-mentioned prior art is not suitable for melamine veneer products. First, one of the main product advantages of melamine veneer is that it can present very realistic and delicate wood grain patterns and texture, and if the conventional paint and film technology is used to achieve antibacterial effect, that is, antibacterial paint is coated on the surface of the melamine veneer, and then a scratch-resistant film is covered, the wood grain pattern on the surface of the melamine veneer will lack realism and clarity, and the embossed simulated lines on the surface of the melamine veneer will also be covered and lose touch, resulting in the loss of product advantages of melamine veneer. Secondly, the existing antibacterial veneer has high hardness, which can only be attached to flat surfaces, but cannot be attached to non-planar structures such as rounded corners, chamfers, and grids, which prevents the furniture from achieving overall antibacterial function. Finally, the surface of the veneer made by the prior art still has the problem of water accumulation, which causes the veneer to be prone to mold in the future. SUMMARY
