Problems solved by technology

For example: water-based anti-graffiti coatings have poorer film fullness than oil-based ones, and at the same time have the disadvantage of insufficient film hardness; PU two-component oil-based anti-graffiti coatings take a long time to dry, and are prone to dust during the drying process of the paint film. It needs to be mixed with curing agent and diluent for construction, and VOC emission is poor in environmental protection; although traditional UV light-cured coatings have the advantages of high film hardness, good wear resistance, and high curing efficiency, high-pr

[0039] Example 1

[0040] The LED-UV anti-graffiti and anti-fouling paint of this embodiment is composed of the following components by weight:

[0041] 4.5-functional fluorosilicone acrylate resin 25kg; low-energy curing special functional acrylic resin 25kg; 8-functional hyperbranched polyester acrylic resin 19.7kg; monomer 25kg; photoinitiator 4kg; wetting and dispersing agent 0.3kg; Foaming agent 0.4kg, anti-graffiti aid 0.6kg;

[0042] Get each component according to the weight shown in Example 1 in Table 1, and the preparation method is as follows:

[0043] Step 1, under the condition of avoiding sunlight or ultraviolet light, add 4.5-functional fluorosilicone acrylate resin, low-energy curing special functional acrylic resin, 8-functional hyperbranched polyester acrylic resin and monomer according to the above weight. Put it in the paint container and disperse it evenly, then add the photoinitiator and the wetting and dispersing agent in turn and stir at a stirring spee...

Abstract

The invention discloses an LED-UV (light-emitting diode-ultraviolet) anti-doodling pollution-resisting coating, which can be used to coat the surface, which is polished and cleanly dedusted in advance, of a to-be-coated object through brush coating or spray coating according to the coating weight to 80g/m<2>; photocuring is performed immediately through illuminating by a portable LED-UV lamp for 5 to 8 seconds after the brush coating is finished; the LED-UV anti-doodling pollution-resisting coating is prepared from the following components in parts by weight: 25 to 35 parts of 4.5 functional silicofluoride acrylate resin, 21 to 30 parts of low-energy cured special functional acrylic resin, 10 to 20 parts of 8 functional hyperbranched polyester acrylic resin, 20 to 25 parts of monomer, 4 to 5 parts of photoinitiator, 0.3 to 0.5 part of wetting dispersant, 0.3 to 0.5 part of defoamer and 0.6 to 0.8 part of anti-doodling additive; a paint film has excellent properties of anti-doodling, pollution prevention, easiness in cleaning, water proofing, oil resistance and chemical resistance; the paint film is compact and smooth, and is high in hardness and good in pollution tolerance.

Description

technical field [0001] The invention relates to an LED-UV functional paint, in particular to a composition of an LED-UV anti-graffiti and anti-fouling paint, a preparation method and an application method thereof. Background technique [0002] In daily life, exterior surfaces such as decorative exterior walls, bus stop signs, and communication and power facilities are often scribbled with water-based or oil-based pens or pasted with various small advertisements, which seriously affects the appearance of the equipment and the overall environment, requiring sanitation workers It is time-consuming and labor-intensive to eradicate the small advertising paper with a spatula, and to clean the graffiti and dirt with a water-based or oil-based pen with a wet towel, but it cannot be completely removed. [0003] In order to solve this phenomenon, many companies have successively developed various anti-graffiti and anti-fouling coatings such as water-based, oil-based, traditional light...
