A waterborne matte varnish and a preparation method thereof
By using specific microspheres to form a microstructure in water-based matte varnishes and combining them with a single film-forming substance, the problems of decreased transparency and poor matting effect at high incident angles in existing technologies have been solved, resulting in water-based matte varnishes with high transparency and excellent matting effect.

AI Technical Summary
Existing water-based matte varnishes suffer from problems such as reduced transparency, poor scratch resistance, and poor matte durability when achieving a matte effect, especially at high incident angles where the matte effect is not ideal.
Sodium alginate microspheres, polyvinyl alcohol microspheres, or cellulose hydrogel microspheres are used as matting microspheres. Their water absorption and expansion and water loss and shrinkage properties are utilized to form a hammer-like microstructure on the paint film surface. Combined with silicone acrylic emulsion as a single film-forming substance, the difference in refractive index of multi-component systems is avoided. The particle size and addition amount of microspheres are adjusted to control the size and density of the uneven structure.
It significantly improves the transparency and matte finish of the paint film, overcomes the problem of poor matte effect at high incident angles, and enhances the scratch resistance and matte durability of the paint film.
