A kind of antifouling, antiglare radiation curing coating composition

Abstract

The invention discloses an anti-flouring anti-dazzle radiation curing coating composition which comprises the following components in parts by weight: 25-40 parts of fluorine modified acrylic ester oligomer, 50-65 parts of acrylic ester oligomer, 10-20 parts of an acrylate monomer with the functionality of 1-6, 0.2-5 parts of an anti-electrostatic additive, 4-6 parts of a photoinitiator, 0.1-2 parts of an anti-flouring additive, 0.2-3 parts of anti-dazzle particles and 0.5-2 parts of an additive. Compared with the prior art, the coating composition is relatively high and long-lasting in synergistic effect of flouring prevention, electrostatic resistance and dazzle resistance, and a coating is low in coating equipment requirement, high in operability and relatively wide in coating mode.

Description

Technical field [0001] The invention relates to the field of radiation curing coatings, in particular to an anti-fouling and anti-glare radiation curing coating composition. Background technique [0002] When the eyes are stimulated by too strong light, that is, glare, they will be damaged, and it will cause dizziness and other adverse reactions. With the rapid development of electronic products, human beings have more and more contact with displays. The luminescence of the display itself and the reflected light caused by external light on the screen often cause eye fatigue, especially when exposed to strong outdoor light. Therefore, it is becoming more and more important to conduct anti-glare treatment on the surface of the display screen or other transparent protective cover to reduce the damage of glare to the eyes and body. [0003] At present, one method of anti-glare treatment is to coat or bond a matte high-hardness coating protective film on the surface of the display. Thi...

Problems solved by technology

[0004] Patent CN101299073 mentions that a kind of antifouling and antiglare coating can be obtained after adding modified silicone acrylic acid and antiglare particles to UV coating and curing. This coating does not have antistatic property and is easy to adhere to dust. The added anti-glare particles are not treated, and are prone to precipitation; CN101235244 relates to a UV light-cured coating with organic-inorganic silica particles, which improves the light transmittance of the coating, but it still does not have antistatic properties; patent No. CN1084774 mentions a kind of antistatic, anti-glare coating, but does not have antifouling performance, after sticking on the coating, it is not only difficult to wipe clean, but the more you wipe, the larger the dirt area tends to be. In addition, the coating is Thermal curing and non-UV light curing have low efficiency and high energy consumption; CN101251608, CN101354454, and CN102762644 use organic particles to achieve the purpose of anti-glare, but in the presence of monomers or solvents, organic particles will swell, and after swelling It will reduce the anti-glare effect of the coating, that is, reduce the storage time of the coating. In addition, after the organic particles settle and add swelling effect, it will form a hard lump at the bottom of the container, which is difficult to completely stir again. In addition, it does not achieve anti-glare, anti-fouling, The effective combination of antistatic three properties, its common synergistic effect also can't show; CN101679798, CN102959020, CN102676004 have antiglare function, but do not have antifouling property or antistatic property; Application number CN103555156 relates to an antifouling, antistatic Static coating, but it does not have anti-glare function; CN103351677 adds fluorine, silicon additives, antistatic additives, and antifouling resins to UV light-curing coatings, and after the matte roller embosses the matte effect, the coating has both Anti-static, anti-fouling, anti-glare three properties, but the use of rolling to obtain anti-glare performance will significantly reduce the effect of anti-fouling, anti-static, because after coating, anti-fouling, anti-static additives Only when it migrates to the surface can it fully express its effect, but the complete structure of anti-fouling and antistatic additives distributed on the coating surface will be destroyed when embossed by the matte roller. In addition, this method requires high precision and uniformity of the matte roller. With the wear of the matte roller in production, the haze and anti-glare effect will change and affect the stability of the product. Finally, this method is not suitable for thicker plates, because the adhesion of the thicker plate to the matte roller is difficult to control and the roll operation is inconvenient.
