Method for coloring wood by fermenting microorganisms

Abstract

The invention discloses a method for coloring wood by fermenting microorganisms, which is characterized by comprising the following steps: thoroughly cooking whole grains and cooling to room temperature; adding white vinegar, dietary alkali or soaking filtering water of plant ash and alcohol yeast for mixing and stirring to be uniform; placing the mixture into a clean container for sealing and then placing at a place the ambient temperature of which is 0-60DEG C for over 24 hours; deslagging and filtering to obtain fermentation liquor; coating the fermentation liquor on a coloring surface of the wood; sealing and wrapping with a thin film or an agricultural film for fermentation; placing the wood at a place the ambient temperature of which is 0-80DEG C; and coloring after fermenting for over 2 hours. All raw materials used by the invention are nuisanceless; the wood can be colored under the action of fermenting the microorganisms on the wood without volatile organic solvent and toxic compound; harmful gases cannot be generated during use; and in addition, the invention can prevent the environmental pollution and ensure the health of people and has lower production cost.

At the same time, people are paying more and more attention to the pollution caused by the coloring of wood products. That is, wood products need colorants to be colored, and colorants will emit harmful gases such as formaldehyde, which will have harmful effects on the human body. It has a strong stimulating effect on the skin and mucous membranes, and it will also lead to a decrease in immunity, which will cause great harm to people's health.

Although wood products with high content of formaldehyde and other harmful gases have been banned by the country, due to the processing characteristics of wood products, existing wood products on the market will still contain a certain amount of formaldehyde and other harmful gases, and the manufacture of such products contains a certain amount of The cost of wood products with harmful gases such as formaldehyde is higher
