Abstract

The invention relates to an industrial super-convenient superhydrophobic finish-coat paint which is prepared from the following components: tetraethyl orthosilicate, ethanol, water, hexadecyl trimethoxy silane, and two or more than two of nanoscale colloidal silica dispersions with different sizes. The nanoscale colloidal silica dispersions with different sizes are mixtures of a nano colloidal silica aqueous dispersion R301 and a nano colloidal silica aqueous dispersion R1050 with the weight ratio of 8:2 to 3:7. The shortcomings of a conventional superhydrophobic finish-coat paint has rigor reaction, complex process and long time are overcome, and the finish-coat paint provided by the invention maintains extremely high hydrophobicity, can be industrialized, and is simple and convenient in process.

Description

technical field [0001] The invention relates to an industrialized ultra-convenient super-hydrophobic finish paint and a preparation method thereof, which are applied in the field of functional paint finishes. Background technique [0002] After the material is formed into a film, the contact angle is greater than 150° and the sliding angle is less than 10°, which is called superhydrophobicity. In nature, water droplets on the surface of lotus leaves can roll freely, water striders can walk freely on the water surface, the surface of cicada wings, the surface of rice leaves, etc. are all natural superhydrophobic phenomena. The special self-cleaning effect of the lotus leaf leaving the silt without staining has attracted great research interest from scientists, and has broad application value in daily life. For example, Shen et al prepared a superhydrophobic surface on the surface of stainless steel, which can play an anti-corrosion role. Using the super-thin surface on the ...
