Description

The present invention is used for a wooden interior or wooden furniture of a building, and is related to a wood surface treatment agent having 100% natural ingredients, which is greatly improved in workability because of its excellent drying property. The present invention relates to a quick-drying wood surface treatment agent having a natural component of 100%, which has a function of improving the aesthetics of wood, such as making the wood grain stand out and further giving the surface gloss.

Various surface treatment agents are used for wood used in wooden interiors or wooden furniture of buildings, and are subjected to treatments for improving aesthetics such as making the grain stand out or glossing. In the surface treatment agent, an organic solvent such as acetone, methyl ethyl ketone, methyl acetate, dioxane, cellosolve or the like is blended as an essential component. However, these organic solvents are harmful to the human body and have high volatility. Therefore, when they are used, it is necessary to sufficiently ventilate the workplace so as not to fill the work space. In addition, when the working time is long, there is a risk of damaging the health of the worker. In addition, organic solvents easily penetrate into wood, so even if the surface is dry, organic solvents will gradually evaporate from inside the wood over a long period of time, causing residents to irritate the nose, eyes, and throat. There were many cases where the human body was adversely affected, such as complaining of headaches. In recent years, paints such as wood surface treatment agents that are friendly to the global environment have been demanded in response to regulations on environmental pollutants. In the housing and furniture industry, allergens such as formalin and other environmental hormones and so-called sick house syndrome such as chemical hypersensitivity have become social problems. Against this background, natural ingredients collected from plants are mainly used. “Eco paint” is being used.

These “eco-paints” include vegetable dry oils such as linseed oil, sesame oil, and tung oil, stand oil and boil oil processed from these dry oils, and orange citral obtained from orange. A wood surface treatment agent mainly composed of essential oil components is being developed and used. However, these products have a long work time of about 2 days and have a problem in work efficiency. In addition, the characteristic unpleasant odor is strong, and the odor gives an unpleasant feeling to the worker, and the odor remains even after drying, giving the resident an unpleasant feeling. Patent Document 1 has been reported as a technique for solving this length of drying time. This uses a lignophenol derivative which is a natural raw material, but in order to dissolve it, an organic solvent harmful to the human body such as acetone or methyl acetate is blended as an essential component. As described above, there are a lot of problems in the current “eco-paints”, and it is hoped to develop a wood surface treatment agent that has solved these problems, that is, 100% natural ingredients that are harmless to the human body and excellent in drying properties. It was rare.
