Problems solved by technology

But usually this effect is not long-lasting. These hydrophilic coatings themselves are not firmly bonded to the hard surface and are easily washed away by water.
Moreover, the easy-to-clean effect of this hydrophilic coating can only be reflected in the presence of water, but it cannot prevent the deposition of pollutants in the air or other non-aqueous environments, including dust, dirt, etc. on hard surfaces.

Embodiment 1

[0065] While maintaining stirring, 10 g of 20% by weight polydimethyldiallylammonium chloride, 16.7 g of 30% by weight Nalco 1056 were sequentially added to 73.3 g of deionized water, and stirred for 10 minutes. The obtained clear and transparent solution was wiped on the glass with a paper towel, and dried naturally at room temperature for 30 minutes. The final obtained glass has a hydrophilicity of 5 and an anti-fouling ability of 5. After rinsing for 20 minutes, the hydrophilicity was 4.

Embodiment 2

[0067] While maintaining stirring, 0.1 g of 20% by weight polydimethyldiallylammonium chloride, 6.7 g of 30% by weight of Nalco 1056 were sequentially added to 93.2 g of deionized water, and stirred for 10 minutes. The obtained clear and transparent solution was wiped on the glass with a paper towel, and dried naturally at room temperature for 30 minutes. The final obtained glass has a hydrophilicity of 4 and an anti-fouling ability of 5. After rinsing for 20 minutes, the hydrophilicity is 3.

Embodiment 3

[0069] While maintaining stirring, 2.5 g of 20 wt % polydimethyldiallylammonium chloride, 0.17 g of 30 wt % Nalco 1056 were sequentially added to 97.33 g of deionized water and stirred for 10 minutes. The obtained clear and transparent solution was wiped on the glass with a paper towel, and dried naturally at room temperature for 30 minutes. The final obtained glass has a hydrophilicity of 5 and an anti-fouling ability of 5. After rinsing for 20 minutes, the hydrophilicity is 3. The solution stability is 5.

Abstract

The invention provides a surface treatment composition comprising a polymer of cationic monomers and inorganic nano particles with the particle size of 10-20nm, wherein the polymer is selected from a homopolymer of quaternary ammonium salt cationic monomers, a copolymer composed of the quaternary ammonium salt cationic monomers and acidic anionic monomers or a mixture thereof. The invention also provides a product comprising a substrate and a hydrophilic coating formed through coating the surface treatment composition on at least one part of surface of the substrate.

Description

technical field [0001] The present invention relates to a surface treatment composition and products, in particular to a surface treatment composition with an anti-fouling and easy-to-clean effect, especially a surface treatment composition for hard surfaces such as glass surfaces, and a surface treatment composition formed with the composition coated products. Background technique [0002] Surface cleaning, especially the cleaning of hard surfaces, such as glass, has always been a common concern in life. Various surface cleaners have also emerged at the historic moment, and most of these cleaners only have a cleaning effect, but do not have the preventive effect for re-pollution after cleaning. Some cleaners add hydrophilic polymers, which can form a thin layer of hydrophilic coating on the cleaned surface after cleaning, so that when water drops onto the surface, it can spread out, and it is not easy to form water stains. Contaminated dirt and dust can be easily washed a...
