Problems solved by technology

The decorative material prepared by the method has good surface coating bonding performance and antibacterial and antifungal properties at the initial stage of use. Unavoidable friction and collision during use, the antibacterial and antifungal coating materials on the surface are prone to fall off, affecting its antibacterial and antifungal properties, and the antibacterial life is short
A large number of patent documents and published research papers have been searched, and it has not been found that wollastonite powder and vinyl chloride-vinyl acetate copolymer resin are used as basic raw materials, and vinyl triethoxysilane, antibacterial agents, antifungal agents, and methyl mercaptan are added. Tin, etc., using coupling, dispersion, blending, banburying, extrusion, and calendering techniques to prepare high-fill antibacterial and mildew-proof laminated panels

Abstract

The invention relates to a method for preparing a high-fill antibacterial and mildew-proof veneer. The preparation method uses 73-81 parts of wollastonite powder and 12-20 parts of vinyl chloride-vinyl acetate copolymer resin as basic raw materials, adding 1.0-1.8 parts of vinyl triethoxysilane, 1.2-2.0 parts of oleic acid amide, 1.4 ~2.4 parts of antibacterial agent, 0.5~1.0 part of antifungal agent, 0.4~0.8 part of tin mercaptide, 1.5~2.5 parts of titanium dioxide, processed by coupling, dispersion, blending, banburying, extrusion and calendering to make. The veneer prepared by the method can effectively inhibit the growth and reproduction of Escherichia coli, Staphylococcus aureus, Aspergillus niger, green fungus, and yeast, and has good antibacterial and antifungal durability, and has excellent flame retardancy, waterproof, Corrosion-resistant, friction-resistant, impact-resistant, etc., suitable for veneer decoration of desktops, cabinets, door panels, and furniture.

Description

technical field [0001] The invention relates to a method for preparing a veneer, in particular to a method for preparing a highly filled antibacterial and mildew-resistant veneer. Background technique [0002] With the improvement of people's living standards, people are constantly pursuing fashion, beauty, elegance, and environmental protection in decoration materials. Various types of veneers have emerged and developed rapidly. Laminated panels, plastic laminated panels, metal foil laminated panels, etc., are widely used in furniture, cabinets, door panels, window sills, tabletops, and countertops, making the interior decoration look new, adding beauty and class. However, relevant personnel tested the hygienic performance of the surface of the veneer after one month of use, and found that the surfaces of the above four types of veneer were breeding and multiplying pathogenic bacteria such as Staphylococcus aureus and Escherichia coli, as well as Aspergillus niger, green P...
