Wood lacquer is often used as a protective lacquer for furniture, which greatly improves the abrasion resistance, scratch resistance, and corrosion resistance of furniture, thereby increasing the service life of wood furniture.
Water-based wood paint is also an environmentally friendly product that has developed rapidly in recent years.
Water-based wood paint produced by adding water-based additives has many advantages:
1.
High film transparency, soft paint film and high solid content;
2.
The water-soluble system does not contain APEO, VOC and other harmful substances;
3.
High cost performance, harmless to the safety of construction personnel;
4.
The construction is convenient, and the bubble phenomenon is reduced;
5.
Good hand feeling, particularly smooth, water-resistant and abrasion-resistant.
However, the use of wood lacquer also requires skill.
Common problems are as follows:
Poor paint film adhesion
After the general water-based wood paint is applied, it will be found that the bonding between the coating layers is not strong, resulting in poor com" href="http://">adhesion .

White paint
It is mainly caused by the high humidity in the construction environment and the thick coating during the construction process.
The temperature in summer is high, and the air humidity in some areas is relatively high.
Cracked paint film
This phenomenon is also common in summer construction.
In the construction process, the paint film is too thick, which causes the surface layer to dry and form a film quickly, while the thick inner layer dries slowly, directly causing the primer to crack.
Paint film wrinkles
When flat coating, one-time thick coating is used, and the result is excellent.
However, at high temperatures, the surface layer of the paint film dries quickly to form a film, while the thick inner layer dries slowly.
Application of water-based wax in wood paint
How to improve the above-mentioned problems of wood lacquer has been deeply researched at home and abroad.
Studies have shown that the addition of wax emulsion can greatly improve the surface properties of wood paint.
Not only can it enhance the abrasion resistance, scratch/scratch resistance, and high temperature adhesion resistance of wood paint, but also improve the feel and gloss of wood furniture.
Production of high melting point polyolefin wax water dispersion by emulsification method
Polyethylene wax, polypropylene wax, and Fischer-Tropsch wax can be made into 4-10μm water dispersion, which can improve scratch resistance and abrasion resistance in water-based coatings.
The wax water dispersion produced by the emulsification method overcomes the dispersion problem in the coating.
The wax (oily) melted at high temperature will form dispersed particles of reasonable size under the high shear action of the emulsifier and equipment, and then turn into solid particles after cooling.
