Description

Technical Field

[0001] The invention belongs to the technical field of coatings, and particularly relates to an environmentally friendly, odorless, water-boiling-resistant wood wax oil and a preparation method and application thereof. Background Art

[0002] Compared with other common paints on the market, wood wax oil cannot cover up the defects and scars on the wood, but this is both its disadvantage and its advantage. Because the wood grain of many precious woods is very distinctive, using wood wax oil can not only protect the wood, but also fully display the characteristics of the wood.

[0003] At present, in the wood paint industry, especially in the coating of solid wood furniture, wood wax oil is used more and more widely. After using wood wax oil, it can not only play a role in maintenance, but also form a protective layer on the surface of the wood, making the wood more wear-resistant, thereby extending the service life. In addition, relevant experiments have shown that when comparing wood coated with wood wax oil with wood coated with ordinary paint, the use time of wood coated with wood wax oil will be significantly longer than that of ordinary paint after the same use and maintenance.

[0004] Traditional wood wax oil is mainly extracted from zelkova oil, pine oil, plant resin and natural pigments. The problem is that it has a strong odor before and after construction, and its oily smell cannot be eliminated for a long time after drying and forming a film. In particular, some oils also emit an unpleasant rancid smell, which has long troubled consumers. In addition, traditional wood wax oil has poor water resistance and is easy to turn white and fall off.

[0005] Therefore, it is necessary to develop a kind of environmentally friendly and tasteless wood wax oil with good water resistance. Summary of the invention
