Embodiment 1

[0048] Prepare a kind of hydrophobic, stain-resistant and anti-adhesive nanocomposite finish paint (percentage by weight) of the present invention according to the following ratio:

[0049] A. Silicone acrylic emulsion 10%

[0050] B. Fluorinated polyether 7%

[0051] C. Nano calcium carbonate 5%

[0052]D. Nano titanium dioxide 5%

[0053] E. Water 70%

[0054] F. Thickener NLS200 1.5%

[0055] G. Wetting and dispersing agent SK5040 1.5%.

[0056] Preparation method: first, 30 grams of nano-calcium carbonate and 30 grams of nano-titanium dioxide are added to a stainless steel container with 131 grams of water at a stirring speed of 4000 r / min. Polycarboxylate wetting and dispersing agent SK5040. After high-speed dispersion for 1 hour, a nano-colloid with a solid content of 30% was formed, and the nano-colloid was further sanded for 1 hour. Then, mix and disperse the sand-milled nano-colloid, 60 grams of silicon-acrylic emulsion, 42 grams of fluorosurfactant fluorine-co...

Embodiment 2

[0060] A hydrophobic, stain-resistant and anti-adhesive nano-composite finish coating, each component and content are as follows (percentage by weight):

[0061] A. Nano-modified silicone acrylic emulsion 5%

[0062] B. Liquid polysiloxane with functional groups 10%

[0063] C. Micron Zinc Oxide 2%

[0064] D. Submicron alumina 3%

[0065] E. Ethanol 5%

[0066] F. Water 75%

[0067] Preparation method: other steps are the same as in Example 1, except that in this example, no wetting and dispersing agent is added when the filler is dispersed into a high-concentration suspension. There is no milling process involved in dispersing the filler into a highly concentrated suspension and no thickeners are added.

Embodiment 3

[0068] Embodiment 3: a kind of hydrophobic, stain-resistant and antisticking nanocomposite finish paint, each composition and content are as follows (weight percentage):

[0069] A. Silicone resin 5%

[0070] B. Fluorinated polyether 10%

[0071] C. Nano silica 6%

[0072] E. Wetting and dispersing agent BYK180 1%

[0073] F.200# solvent oil 78%

[0074] Preparation method: first, add 60 grams of nano silicon dioxide into a stainless steel container containing 110 grams of 200# solvent oil at a high stirring speed of 4000 r / min, and 6 grams of wetting and dispersing agent BYK180 are pre-dispersed in water. After high-speed dispersion for 1 hour, a nano-colloid with a solid content of 30% was formed, and the nano-colloid was further sanded for 1 hour. Then, the sand-milled nano colloid, 50 grams of silicone resin, 50 grams of fluorine-containing polyether, 670 grams of 200# solvent oil and other components were stirred, mixed and dispersed for 30 minutes at a speed of 1000 ...

Abstract

The invention relates to a nanometer compound cover paint which has the hydrophobicity and is resistance to the pollution and the sticking. The paint contains the film forming material, the antifouling component, the filler and the diluting agent, necessary the wetting agent, dispersant and the thickener. So it can be used for the antifouling of the high-end building and the protection for the outlook of the public utility.

Description

technical field [0001] The invention relates to a paint and a preparation method thereof, in particular to a hydrophobic, stain-resistant and anti-adhesive nano-composite finish paint and a preparation method thereof. Background technique [0002] The surface of ordinary coatings has very weak anti-sticking properties, and is easily polluted by various pollutants such as dust and oil stains. The surface of the lotus leaf in nature has a good ability to reduce surface tension, so it has good water repellency, and it is not stained by sludge, so many lotus leaf effect coatings have emerged as the times require. [0003] Large-scale research on nanocomposite coatings at home and abroad began in the 1990s. The NanoTufCoatings transparent ultra-wear-resistant nano-coatings produced by TritonSystem Company of the United States add organically modified nano-china clay to the polymer resin base, and the prepared coatings can greatly improve the hardness, scratch resistance and wear...
