Abstract

The invention discloses an ultraviolet curable coating, which comprises the following components in parts by weight: 10-20 parts of fluorine-containing acrylate polymer, 30-45 parts of photocurable resin, 30-40 parts of acrylate active monomer, photoinitiator 3-10 parts of agent, 0.5-5 parts of coupling agent, 0.3-1 part of leveling agent and 0.5-8 parts of lotus leaf powder. Lotus leaf powder is added to the UV-curable coating of the present invention, and the super hydrophobicity of lotus leaf powder is utilized, combined with fluorine-containing acrylate polymer and photocurable resin, the hydrophobicity of the coating can be increased, and the cured coating can be made The water contact angle is greater than 150.0°, forming a "lotus leaf effect", forming a superhydrophobic coating, improving the hydrophobicity and anti-fouling ability of the cured coating, and avoiding the colloid caused by adding too much fluorine or silicon to the coating. Problems with opacity and poor strength. The invention also discloses a preparation method of the ultraviolet curing paint.

Description

technical field [0001] The invention relates to a coating, in particular to a superhydrophobic ultraviolet-curable coating and a preparation method thereof. Background technique [0002] Superhydrophobic coatings refer to coatings with a contact angle of water droplets greater than 150.0° on the surface, which is related to the chemical composition and microscopic geometry of the solid surface. For the self-cleaning and anti-fouling functions of UV light-curing coatings, the more commonly used method is to introduce low surface tension silicon or fluorine structures into the molecular structure, but the coatings obtained by this method have low water contact angles and cannot meet the requirements of superhydrophobicity. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies in the prior art and provide a super-hydrophobic, ultraviolet fast curing (water drop angle > 150.0°) coating and a preparation method thereof.
