[0066] Correspondingly, as figure 1 As shown, the embodiment of the present invention also provides a preparation method of anti-graffiti anti-sticking nano-coating, including:

[0067] S100, add epoxy resin, glycidoxypropylmethyldiethoxysilane, phenyltrimethoxysilane, butanol, and butyl acetate into the reaction kettle, heat and stir at 50~80°C for 5~ After 7 hours, the matrix component was obtained.

[0068] Preferably, epoxy resin, glycidoxypropylmethyldiethoxysilane, phenyltrimethoxysilane, butanol, and butyl acetate are put into a reaction vessel and heated and stirred at 60-70°C for about After 6 hours, the matrix component was obtained.

[0069] S101, adding the precursor, tetraethyl orthosilicate, deionized water, butanol, and catalyst into the reaction kettle, heating and hydrolyzing at 55-80° C. for 7-9 hours to obtain the solidified component.

[0070] Preferably, the precursor, tetraethyl orthosilicate, deionized water, butanol, and catalyst are put into a react...

Embodiment 1

[0102] Add 46 parts of bisphenol A type epoxy resin, 18 parts of glycidoxypropylmethyldiethoxysilane, 13 parts of phenyltrimethoxysilane, 10 parts of butanol, and 13 parts of butyl acetate into the reactor Heated and stirred at 60°C for 5 hours to obtain the matrix components; 16 parts of aminomethylsilane, 32 parts of ethyl orthosilicate (type 28), 3 parts of deionized water, and 4 parts of hydrochloric acid were prepared by sol-gel method. Heat and hydrolyze at 60°C for 7.5 hours to obtain nano-silica colloid; dissolve 45 parts of butanol in the nano-silica colloid to obtain a cured component; mix the matrix component with the cured component at a ratio of 1:1 , to obtain anti-graffiti and anti-paste nano coatings.

[0103] The coating of Example 1 is sprayed on the specified base material, and after curing to form a film, the formed paint film is subjected to a performance test, and each performance test result and the following table:

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to an anti-graffiti and anti-sticking nano coating and a preparation method thereof. Background technique [0002] Coatings are applied to the surfaces of various objects, such as concrete, ceramics, metals, wood and other materials, to play a protective role, and are used in many industries, which shows its importance. For a long time, the weather resistance and wear resistance of coatings have been emphasized, but the stain resistance and anti-sticking properties of coatings have been ignored. In recent years, in order to improve the stain resistance and anti-sticking properties of coatings, the research on hydrophobic and oleophobic nano coatings has been intensified. [0003] Most of the stains in daily life are oily and water-based, so the hydrophobic and oleophobic properties of the coating can improve its stain resistance. At present, there are roughly two methods to make ...
