Embodiment 1

[0035] A super-hydrophobic finish paint with high adhesion, which is formulated by the following components by weight:

[0036]

[0037] The preparation method of this high-adhesion superhydrophobic finish paint, it comprises the following steps carried out in sequence:

[0038] ① Add ethanol to tetraethyl orthosilicate and stir to dissolve, then add ammonia water, stir in a 60°C water bath at a speed of 450rpm for 80min, and then remove ammonia gas until there is no ammonia smell;

[0039] ②Add γ-aminopropyltriethoxysilane, γ-diethylenetriaminepropylmethyldimethoxysilane, and 0.001mol / L oxalic acid solution to the mixture prepared in step ①, and heat up to 80°C. Stir at a speed of 450rpm and react for 45min, then add hexadecyltrimethoxysilane and water, stir at a speed of 450rpm and react for 4.5h, and finally place the mixture in ice water, and wait for it to cool completely to obtain high-adhesive Focus on super-hydrophobic finishes.

Abstract

The invention relates to high-adhesion super-hydrophobic finish-coat paint which is prepared from the following components: tetraethoxysilane, ethanol, ammonia water, monoamino methoxylsilane or monoamino triethoxy methylsilane, polyamino methoxylsilane or polyamino triethoxy methylsilane, 0.0005 to 0.0015mol / L oxalic acid solution, a hydrophobic modifying agent and water. According to the paint provided by the invention, the problems that an existing preparation method is complex in process, expensive in cost, long in time consumption and the like are overcome, the paint has the advantages of simple process and low cost, has the characteristic of super high adhesion, is beneficial for maintaining the super-hydrophobicity of a paint film, the paint film contact angle is between 150 to 160 degrees, and the adhesion is 90 to 100 percent.

Description

technical field [0001] The invention relates to a high-adhesion superhydrophobic finish paint and a preparation method thereof, which are applied in the field of functional paint finish. 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 outdoor antenna can pr...
