Problems solved by technology

However, since this method requires long-term ultraviolet light to obtain a response, it cannot be applied outdoors. Even if the super-hydrophilic phenomenon is produced after long-term outdoor light, once the light is lost, it will take a long time to respond again.
However, the super-hydrophilic surface produced by surfactants can only last for a few days and cannot be used indoors for a long time.

Embodiment 1

[0034] Dissolve 20g of TEOS (tetraethyl tetrasilicate) in 80g of absolute ethanol, add nitric acid to adjust the pH to 2, stir at 45°C for 24 hours to obtain a stable sol solution, add 2g of hydroxyl-modified perfluoropolyether and 0.1ml of lauric acid Butyltin, stirred for 24H. Add 0.5g of gas-phase nano-silica, and disperse for 1H under high-speed shearing to obtain an anti-fouling nano-scale easy-to-clean coating solution. Spray the coating solution on the surface of household ceramics and glass with a pressure spray gun to make it level naturally, and test it after 24 hours.

Embodiment 2

[0036] Dissolve 20g of TEOS in 80g of absolute ethanol, add nitric acid to adjust the pH to 2, stir at 45°C for 24H to obtain a stable sol solution, add 2g of hydroxyl-modified fluorine-containing acrylic resin and 0.1ml of butyltin laurate, and stir for 24H. Add 0.5g of gas-phase nano-silica, and disperse for 1H under high-speed shearing to obtain an anti-fouling nano-scale easy-to-clean coating solution. Spray the coating solution on the surface of household ceramics and glass with a pressure spray gun to make it level naturally, and test it after 24 hours.

Embodiment 3

[0038] Dissolve 20g of tetrabutyl titanate in 80g of isopropanol, add 10% acetic acid until the pH is 4, the speed of adding acetic acid must be controlled to be very slow, and it takes at least 4 hours to complete the dropwise addition. , to obtain a stable sol solution, add 2g of hydroxyl-modified perfluoropolyether and 0.1ml of butyltin laurate, and stir for 24H. Add 0.5g of gas-phase nano-silica, and disperse for 1H under high-speed shearing to obtain an anti-fouling nano-scale easy-to-clean coating solution. Spray the coating solution on the surface of household ceramics and glass with a pressure spray gun to make it level naturally, and test it after 24 hours.

Abstract

The invention relates to a surface hydrophobing agent, particularly to an antifouling anti-scale nano easy-to-clean coating solution, and a preparation method and application thereof. The preparation method of the antifouling anti-scale nano easy-to-clean coating solution comprises the following steps: (1) dissolving a silane coupling agent or a titanate coupling agent and an active-group-containing perfluorinated organic matter in C2-C5 saturated monohydric alcohols, regulating the pH value to 2-4 by using an acidic catalyst, adding a curing agent, and performing a reaction at 40-60 DEG C to form a gel liquid; and (2) adding nano fumed silica into the transparent gel liquid obtained in the step (1), and performing uniform dispersion to obtain the antifouling anti-scale nano easy-to-clean coating solution. The antifouling anti-scale nano easy-to-clean coating solution provided by the invention is hydrophobic and oleophobic; low surface energy is achieved; the surface is easy to clean; and the coating solution is capable of resisting fouling and scales, is transparent and friction-resistant, and can be stored stably. The coating solution has the characteristics of favorable chemical stability and the like, and can be cured at normal temperature. The production technique is simple, and is suitable for large-scale production and application.

Description

technical field [0001] The invention relates to a surface hydrophobic agent, in particular to an anti-fouling nanometer easy-to-clean coating solution and its preparation method and application. Background technique [0002] Shower room and bathtub in the indoor bathroom. Surfaces such as washbasins, tiles or toilets are often left with scale due to contact with water or detergent, which is difficult to wipe off after a long time, and is prone to mold and yellow. It greatly affects the appearance. Forming a layer of low surface energy hydrophobic or hydrophilic surface on the surface of glass or ceramics can effectively prevent the occurrence of such troubles in life. [0003] The current technology mainly focuses on two directions, that is, the super-hydrophilic surface, which uses the spreading of water on the surface of the substrate to take away the dirt. The low surface energy hydrophobic surface uses the principle that the low surface energy dirt adhesion decreases,...
