Problems solved by technology

[0004] At present, the commonly used methods to remove wood mildew are through finishing paint and chemical treatment, but the effect is poor, and the paint is easy to wear after a long time. The advantages of chemical anti-mildew are that it has a good anti-mold effect and does not damage the structure of the wood itself. The disadvantage is that the chemical agent has certain toxicity to the environment and the human body, and the treatment process is relatively complicated. Generally, it is necessary to use vacuum pressure to strengthen the penetration of the agent in the wood.

Abstract

The invention belongs to the technical field of wood processing and specifically relates to a method for preventing wood mould. The method comprises the following steps: (1) preparation of a complex enzyme preparation: dissolving 10-20 parts by weight of protease, 15-30 parts by weight of amylase and 2-5 parts by weight of a surfactant in 100 parts by weight of water to obtain the complex enzyme preparation; (2) enzyme treatment on wood surface: coating the wood surface with the complex enzyme preparation in the step (1), and standing; (3) anti-mould treatment on wood: soaking the wood treatedin the step (2) with an anti-mould solution prepared from an anti-mould agent. After being treated by the method disclosed by the invention, the anti-mould wood has a perfect anti-mould effect.

Description

technical field [0001] The invention belongs to the technical field of wood processing, and in particular relates to a method for preventing wood mildew. Background technique [0002] With the rise of the home improvement market, the customization of wood products in the whole house is more and more popular among the public, and the consumption is increasing year by year. The consumption of wood in wardrobes, cabinets and other places is relatively large. However, a humid environment is more likely to breed mold. The side of the wardrobe close to the shower in the bathroom is affected by the humid environment for a long time, which is prone to mildew and affects the appearance; the cabinet is also prone to mildew due to frequent contact with the humid environment, which affects the appearance and has a smell. Wood mildew mainly occurs on the surface and sapwood of the wood, making the wood green, black, and occasionally other colors, often flocculent or spotted, and mildew ...
