The basic composition of the formula of water-based wood paint

Water-based wood paint is a paint with water as the dispersion medium and diluent. Different from the commonly used solvent-based paint, its formulation system is a more complex system. When formulating, it is not only necessary to pay attention to the type of polymer, the properties of emulsion and dispersion, but also to choose various additives reasonably and to make a reasonable match by considering the interaction between each component. Sometimes it is necessary to select some special additives according to special requirements, and finally form a suitable formula. 

The basic composition of water-based wood paint is as follows

1. Water. Using water as the main solvent, adhering to the concept of environmental friendliness.

2. Emulsion. This is the base material of the film, which determines the main performance of the paint film. 

3. Film-forming aids. After the water evaporates, the emulsion forms a uniform and dense film, and can improve the film-forming property at low temperature.

4. Foam inhibitor and defoamer. Inhibit the bubbles generated in the paint liquid during the production process, and can eliminate the bubbles that have already occurred.

5. Leveling agent. Provide good flow and leveling properties for the paint, improve the construction performance of the paint, and form a smooth and smooth coating. 

6. Wetting agent. Improve the wetting performance of the paint liquid on the substrate, improve the leveling property, and increase the adhesion of the paint film to the substrate. 

7. Dispersant. Promote the dispersion of pigments and fillers in the paint solution. 

8. Thickener. Increase the viscosity of the paint liquid, increase the wet film thickness of a coating, and have anti-sedimentation and anti-delamination effects on putty and solid-color paint.

9. Antiseptic and fungicide. Prevent the paint liquid from mildewing during storage. 

10. Essence. Gives the lacquer a pleasant smell. 

11. Colorant. Mainly for colored paints, making water-based paints have the desired color. Colorants include pigments and dyes. Pigments are used for solid paints (paints that do not reveal wood grain), and dyes are used for transparent paints (paints that reveal wood grains). 

12. Filling. It is mainly used in putty and solid color paint to increase the solid content. 

13. pH regulator. Adjust the pH value of the paint solution to stabilize the paint solution. 

14. Wax emulsion or wax powder. Improve the scratch resistance of the paint film and improve its feel. 

15. Special additives. Additives for the special requirements of water-based paints, such as anti-rust agent (iron can packaging to prevent premature rust), hardener (increase the hardness of the paint film), matting agent (reduce the gloss of the paint film), anti-scratch agent, Slip agent (to improve the feel of the paint film), anti-blocking agent (to prevent the coating from laminating and sticking), cross-linking agent (to make a two-component paint to improve the overall performance), water repellent (to make the coating have a lotus leaf effect) , Wear-resistant agent (increase the wear resistance of the coating), UV absorber (anti-aging of outdoor paint, prevent yellowing), etc.
