A kind of antibacterial medium density fiberboard and preparation method thereof

Abstract

The invention provides an antibacterial medium-density fiberboard and a manufacturing method thereof, comprising two parts of inner and outer antibacterial. Antibacterial treatment is carried out on the fiber and the adhesive used for surface decoration paper impregnation, so that the antibacterial medium density fiberboard produced has high antibacterial performance, no toxic decomposition products, environmental protection, and meets the national standard requirements for the basic physical properties of medium density fiberboard.

Description

technical field [0001] The invention relates to the field of wood-based panel decoration materials, in particular to an antibacterial medium density fiberboard and a preparation method thereof. Background technique [0002] With the rapid development of my country's economy and the rapid improvement of people's living standards, there are strict requirements on the formaldehyde emission of furniture, that is, the formaldehyde emission reaches the national standard E1 level, and does not cause harm to human health; The rainy season and occasions with high air humidity (bathroom, toilet, kitchen) can maintain good antibacterial properties, and will not cause rapid growth of bacteria after the fiberboard is damp, which will cause surface stains on decorations and furniture, decrease in mechanical strength, and odor. Pollution of indoor air, in addition, long-term exposure to bacteria by the human body will endanger human health; secondly, during the use of fiberboard, high antiba...

Problems solved by technology

In this regard, the most commonly used treatment method on the market is to directly add an antibacterial agent in a certain link in the process of manufacturing fiberboard, such as mixing the antibacterial agent with wood flour in advance and then sizing or mixing the adhesive with the antibacterial agent when sizing, and No corresponding changes have been made to the main manufacturing processes such as hot pressing process and manufacturing process. Although the antibacterial performance of wood-based panels has been improved, the physical properties of wood-based panels have also been affected to a certain extent, which is not conducive to the subsequent long-term use of users; secondly At present, the antibacterial agents commonly used in the market are still mainly organic antibacterial agents such as quaternary ammonium salts, phenol ethers, organic metals, etc. Although they have the advantages of fast sterilization speed and generally high antibacterial performance, they have a short validity period, especially the decomposition products are often toxic. , long-term exposure will cause a certain degree of damage to the human body, so it is not suitable for use in future development

For example, in patents CN 1292660C and CN104126611B, organic substances are selected as antibacterial agents, such as cetylpyridine chloride and 2n acyl isothiazolone in CN 1292660C, and isothiazolone, triclosan, and nipomol in CN 104126611B. Although gold butyl ester has achieved a strong antibacterial effect, it still affects the use of users to a certain extent because of its toxicity and irritation, and there are potential safety problems
