Abstract

The invention discloses an antifouling self-cleaning nano functional paint and a preparation method thereof. The antifouling self-cleaning nano functional paint comprises a primer and a finish. The invention is characterized in that the primer is prepared by mixing a component A and a component B in a weight ratio of 10:(0.5-1); and the finish is prepared by mixing a component C and a component B in a weight ratio of 10:(1-2). The antifouling self-cleaning nano functional paint has the advantages of ultralow surface energy, superstrong hydrophobicity and oil stain resistance, can reduce the contact area between the water stain / dust and the base surface by more than 90%, and has very excellent automatic cleaning characteristic, so the water stain can roll off on the base surface like on a lotus leaf and can not leave any trace, thereby effectively prolonging the clean keeping time.

Description

technical field [0001] The invention relates to a paint and a preparation process thereof, in particular to a preparation method of an anti-fouling self-cleaning nanometer functional paint. Background technique [0002] Utilizing the lotus leaf amphiphobic mechanism of binary synergy of nanomaterials, using contemporary cutting-edge nanotechnology to produce extremely small nano-sized coloring pigments, and using special technology to make nano-sized pigments stable and long-lasting in the paint slurry. Today's technical nanopigments are usually dispersed in water or mineral oil and cannot be used in paints. [0003] The paint products with certain self-cleaning ability in the prior art are limited by water-based paints, and the contact angle with water after film formation cannot exceed 80°. Therefore, the self-cleaning function is very limited. Contents of the invention [0004] The purpose of the present invention is to overcome the deficiencies of the prior art, to pr...
