Embodiment Construction

[0012] A self-cleaning UV light-curing coating, made of the following raw materials in parts by weight (kg): epoxy acrylic resin 33, nano silicon dioxide 6, phenolic epoxy acrylic photosensitive resin 20, cardanol 8, silane coupling agent KH-550 0.7, styrene 8, isoamyl butyrate 5, pentaerythritol triacrylate 17, benzophenone 2.5, hydroxyethyl acrylate 6, additive 4.5;

[0013] The auxiliary agent is made of the following raw materials in parts by weight (kg): 5 pentaerythritol triacrylate, 6 sodium phytate, 0.4 carbon nanotubes, 1.5 polystyrene maleic anhydride, 0.05 dodecanethiol, 0.1 sodium persulfate , polyethylene wax 0.2, methyl acrylate 2.5, ethyl acetate 7, oligosaccharide 4, isoamyl butyrate 7; the preparation method is to mix sodium phytate, carbon nanotubes, and oligosaccharide at 12000 rpm Add ethyl acetate and isoamyl butyrate under stirring, stir for 8 minutes, then add pentaerythritol triacrylate, polystyrene maleic anhydride, polyethylene wax, methyl acrylate, h...

Abstract

The invention relates to a self-cleaning UV (ultraviolet) photocuring paint which is prepared from the following raw materials in parts by weight: 30-36 parts of epoxy acrylic resin, 5-8 parts of nano silicon dioxide, 18-22 parts of phenol aldehyde epoxy acrylate photosensitive resin, 6-9 parts of cardanol, 0.5-1 part of silane coupling agent KH-550, 6-9 parts of styrene, 4-7 parts of isoamyl butyrate, 16-19 parts of pentaerythritol triacrylate, 2-3 parts of diphenyl ketone, 5-7 parts of 2-hydroxyethyl acrylate and 4-5 parts of assistant. The UV (ultraviolet) photocuring paint has excellent binding property of the epoxy resin; by adding the cardanol, the toughness and hydrophobicity of the resin are enhanced, so that the paint has favorable water resistance; by adding the nano silicon dioxide, the anti-fouling and self-cleaning properties are enhanced; and the paint has the advantages of favorable dispersivity, favorable wear resistance and low tendency to yellowing, and is easy for application. The assistant enhances the dispersivity of the paint, so that the UV (ultraviolet) photocuring paint has favorable leveling property and the coating formed by the paint is smooth and bright.

Description

technical field [0001] The invention belongs to the field of coatings, in particular to a self-cleaning UV light-curing coating and a preparation method thereof. Background technique [0002] The advantages of light-curing coatings are short curing time (a fraction of a second to a few minutes), low curing temperature, and low volatile matter, which are energy-saving, resource-saving, pollution-free, and high-efficiency; but there are still some shortcomings, such as free radical type The curing process of light-curing coatings is inhibited by oxygen, poor surface curing, and a series of problems such as yellowing, explosive color, low temperature resistance, high cost, and poor corrosion resistance, all of which need to be continuously improved for different purposes to reduce production costs , to expand the use. Contents of the invention [0003] The object of the present invention is to provide a self-cleaning UV light-curing coating and a preparation method thereof. ...
