Description

Technical Field

[0001] This invention belongs to the field of coating technology, and specifically relates to an environmentally friendly, odorless, and water-resistant wood wax oil, its preparation method, and its application. Background Technology

[0002] Compared to other common paints on the market, wood wax oil cannot cover up imperfections and knots on wood. However, this is both its disadvantage and its advantage. Because many precious woods have very distinctive grain patterns, using wood wax oil can both protect the wood and fully showcase its unique characteristics.

[0003] Currently, wood wax oil is increasingly widely used in the wood coating industry, especially in solid wood furniture finishing. After applying wood wax oil, the wood not only receives maintenance but also forms a protective layer on its surface, making it more wear-resistant and extending its lifespan. Furthermore, relevant experiments have shown that, compared to wood coated with ordinary paint, wood coated with wood wax oil lasts significantly longer with the same usage and maintenance.

[0004] Traditional wood wax oil is mainly made from tung oil, pine oil, plant resins and natural pigments. Its problems are that it has a strong odor before and after application, and the 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 bothered consumers. In addition, traditional wood wax oil has poor water resistance and is prone to whitening and peeling.

[0005] Therefore, it is necessary to develop an environmentally friendly, odorless wood wax oil with good water resistance. Summary of the Invention

[0006] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention provides an environmentally friendly, odorless, and water-resistant wood wax oil, its preparation method, and its application. The wood wax oil of the present invention overcomes the defects of traditional wood wax oils, such as unpleasant odor and poor water resistance, and has the characteristics of soft gloss, smooth feel, and environmental friendliness and odorlessness after drying.

[0007] In a first aspect, the present invention provides a wood wax oil comprising a component A and a component B; the component A comprises the following raw materials: vegetable oil modified long-oil alkyd resin, acrylic resin, dispersant, hydrocarbon solvent, defoamer, anti-settling agent, matting powder, polytetrafluoroethylene wax powder, and hand feel additive; the component B comprises a hydrocarbon solvent.

[0008] The wood wax oil in this invention is mainly composed of vegetable oil-modified long-oil alkyd resin and acrylic resin, combined with dispersants, hydrocarbon solvents, defoamers, anti-settling agents, matting agents, polytetrafluoroethylene wax powder, and hand-feel additives, and is produced through a mixed processing process. The vegetable oil-modified long-oil alkyd resin exhibits good workability, excellent penetration, extremely high toughness, moderate drying speed, and excellent water resistance. The acrylic resin has good compatibility, is odorless, weather-resistant, and heat-resistant. The combination of these two components provides the wood wax oil with excellent comprehensive performance, effectively protecting the wood and significantly enhancing the value of wooden products. Furthermore, the additives help improve the storage stability of the wood wax oil; for example, matting agents adjust the gloss to meet different product gloss requirements, polytetrafluoroethylene wax powder provides moderate hardness and scratch resistance, and hand-feel additives provide a smooth touch. Through the compounding of various components, the wood wax oil is environmentally friendly, odorless, and possesses good water resistance and other properties.

[0009] In some embodiments of the present invention, the A component comprises, by weight percentage, the following raw materials: 20-30% vegetable oil modified long-oil alkyd resin, 20-30% acrylic resin, 1-2% dispersant, 35-55% hydrocarbon solvent, 0.2-0.3% defoamer, 1-2% anti-settling agent, 1-3% matting powder, 1-3% polytetrafluoroethylene wax powder, and 0.5-1% hand feel additive.

[0020] In some embodiments of the present invention, the matte powder comprises fumed silica.

[0021] In a second aspect, the present invention provides a method for preparing the wood wax oil described in the first aspect, comprising the following steps:

[0022] Prepare component A and component B separately;

[0023] The steps for preparing component A include: mixing vegetable oil-modified long-oil alkyd resin, acrylic resin, dispersant, hydrocarbon solvent, defoamer, anti-settling agent, matting agent, polytetrafluoroethylene wax powder, and hand feel additive, and stirring.

[0024] In some embodiments of the present invention, the step of preparing component A specifically involves: mixing vegetable oil-modified long-oil alkyd resin, acrylic resin, dispersant, defoamer, and a portion of hydrocarbon solvent, dispersing them evenly at a speed of 600–800 rpm, then adding polytetrafluoroethylene wax powder, anti-settling agent, and matting powder at a speed of 300–500 rpm, dispersing them at a speed of 1200–1500 rpm for 10–15 min, then adding a hand feel additive and the remaining hydrocarbon solvent, and dispersing them evenly at a speed of 600–800 rpm.

[0025] In a third aspect, the present invention provides the application of the wood wax oil described in the first aspect of the present invention in closed and open coatings for wood products.
