An antibacterial and mildew-proof multifunctional formaldehyde-free straw wood-based panel and its preparation method

Abstract

The invention discloses an anti-microbial mildew-proof multifunctional type formaldehyde-free straw artificial board. The artificial board comprises a core layer, a surface layer and an anti-microbial mildew-proof negative-ion adhesive layer which is located between the core layer and the surface layer. Anti-microbial mildew-proof negative-ion adhesive comprises, by weight, 100 parts of adhesive special for the formaldehyde-free wheat straw artificial board, 0.3-1 part of an anti-microbial mildew-proof slow release preparation and 3-20 parts of a negative-ion additive. The invention further discloses a preparation method of the anti-microbial mildew-proof multifunctional type formaldehyde-free straw artificial board. According to the anti-microbial mildew-proof multifunctional type formaldehyde-free straw artificial board and the preparation method thereof, the anti-microbial mildew-proof multifunctional type formaldehyde-free straw artificial board is prepared through a formaldehyde-free environment-friendly wood adhesive technology, a negative-ion factor composite technology and an anti-microbial mildew-proof slow release technology; multiple functions such as formaldehyde removal, bacterium resistance and air purification are integrated; and the environment protection function is superior to that of similar products. The environment protection problem of home furnishing is solved; a negative-ion forest environment of an indoor space is created; and the remarkable purification effect is achieved on improvement of the indoor space environment where people live and work.

Description

technical field [0001] The invention relates to the technical field of formaldehyde-free wood-based panels; more specifically, it relates to an antibacterial and mildew-proof multifunctional formaldehyde-free wood-based panel and a preparation method thereof. Background technique [0002] Wood-based panels and their products are widely used in public environments such as vehicles, restaurants, hospitals, schools, entertainment venues and other places. Due to insufficient daily cleaning and disinfection, these places often become breeding grounds for microorganisms and bacteria, seriously affecting people's physical and mental health. Antibacterial is to inhibit the growth and reproduction of microorganisms and kill the vegetative bodies and propagules of microorganisms, showing antibacterial and antifungal properties. Non-wood particleboard made of plant materials such as corn stalks and wheat straw can reach the level of wood particleboard in terms of mechanical strength, b...

Problems solved by technology

[0003] At present, antibacterial agents or antifungal agents are mostly used for the antibacterial treatment of wood-based panels. The antibacterial effect is acceptable, but it has a great impact on the bonding strength of the panels, and there is secondary pollution. Most of the antibacterial panels are coated with antibacterial agents on the surface. Paint or add antibacterial materials to the surface veneer paper, the board itself does not have antibacterial and antifungal effects

Organic antibacterial or antifungal agents have quick effects and strong bactericidal ability, but they are prone to drug resistance to microorganisms, and have shortcomings such as short antibacterial time, easy migration, and poor heat resistance. When used, the drug release is concentrated and cannot achieve long-term effective effects. , and excessive release concentration will cause harm to the environment and human beings

In recent years, with the continuous development of nanotechnology, a number of nano-Ag, nano-ZnO, nano-TiO 2 Inorganic nano-antibacterial materials, studies have shown that they can effectively inhibit bacteria to a certain extent, but their anti-mold performance is not significant

In nature, there are countless types of bacteria and molds. A single-component antifungal agent or antibacterial agent only has a particularly effective killing effect on one or several types of bacteria, and cannot work on all bacteria.
