Embodiment 1
[0019] A super-hydrophobic outdoor water-based wood coating, including the following raw materials in parts by weight:
[0020]
[0021] Wherein, the cage silsesquioxane surfactant is formed by an amphiphilic monomer whose side groups are hydrophilic carboxyl groups and hydrophobic POSS groups, and the polymerized group is styrene.
[0022] The defoamer is Tego901W. The film forming assistant is alcohol ester-12. The dispersant is 5040. The leveling agent is Glide 410. The wetting agent is Tego-500. The thickener is SN-603.
[0023] A preparation method of super-hydrophobic outdoor water-based wood coatings. Under the medium and high-speed dispersion state of 800-1200rpm / min, various auxiliary materials are sequentially added, and the viscosity is adjusted with thickener and deionized water. Installed.
[0024] Use a contact angle measuring instrument to test the contact angle of the coating (deionized water), measure nine water droplets for each sample, and take the average valu...
