Abstract

The invention discloses a mildew-proof agent for artificial boards, and belongs to the technical field of additives for artificial boards. The mildew-proof agent has the advantages that mixed alcoholis added into tetrabutyl titanate which is a titanium source, adsorption thin layers are formed on the surfaces of particles, accordingly, durable and stable antibacterial and mildew-proof effects canbe guaranteed, and the stability of bacterial inhibition agents can be improved; oxidizing agents added into the mildew-proof agent are Jones reagents, alpha-site hydroxyl can be directionally oxidized by the oxidizing agents to obtain aldehyde, beta-site hydroxyl can be directionally oxidized by the oxidizing agents to obtain carbonyl, soybean proteins can be decomposed into different types of amino acid, Schiff base can be formed, accordingly, pore structures inside systems can be densely filled, and the moisture barrier and mildew-proof properties can be effectively enhanced; partial functional group locations in cross-linked networks of the systems can be occupied by added lavender essential oil in preparation procedures, the vibration intensity of covalent bonds in molecules in the cross-linked networks can be lowered, accordingly, the water-resistant performance further can be reinforced, ascorbic acid can have bacterial inhibition performance, and the problem of poor mildew-proof effects of current common mildew-proof agents for existing artificial boards can be solved by the aid of the mildew-proof agent.

Description

technical field [0001] The invention belongs to the technical field of additives for wood-based panels, and in particular relates to an antifungal agent for wood-based panels. Background technique [0002] Wood-based panels are widely used in furniture manufacturing, engineering construction, packaging materials, interior decoration of vehicles and ships, etc. Since the raw materials for the production of wood-based panels are usually biomass materials such as wood, shavings, fibers, straws, etc., in a humid environment, especially in hot and humid places in the south, ordinary fiberboards will be damp and deformed when placed in a humid environment, and they are more prone to mold and damage. Breeding bacteria not only reduces its service life and use effect, but also makes people sick due to the spread of mold spores. The use of antibacterial agents and antifungal agents can effectively kill bacteria and molds, inhibit the concentration of bacteria and molds in people's l...
