UV-cured anti-glare coating and preparation method thereof

Abstract

The embodiment of the invention provides a UV-cured anti-glare coating and a preparation method thereof. The coating can be effectively coated on the surface of glass or a metal substrate; the adhesive force can achieve 100, an excellent anti-dazzle effect is achieved; the haze is 5.4, compared with the prior art, the UV-cured anti-glare coating provided by the embodiment of the invention has theadvantages that a coated base material does not need to be heated, room-temperature spraying and UV curing can be realized, the construction is easy, the curing efficiency is high, the energy is saved, the batch production is facilitated, and compared with a traditional matt powder-added matting process, the gloss is more uniform, the haze is lower, and the cost is lower.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a UV curing anti-glare coating and a preparation method thereof. Background technique [0002] When the position of the light source forms a specific angle with the viewpoint, the high-brightness light source will produce a strong brightness contrast with the surrounding after reflection, which will make the audience feel glare. Glare will not only cause visual discomfort, but strong glare can also damage vision and even cause blindness. Glare belongs to light pollution. For example, the glare reflected by the glass curtain walls of tall buildings in modern cities will cause visual disturbance to pedestrians and affect the normal rest of surrounding residents. The glare generated by roadside lighting decorations and night scene lighting sources will cause sudden temporary blindness and visual illusions, and will instantly block the driver's vision, which is likely t...

Problems solved by technology

CN106634103A discloses a kind of anti-glare UV curing coating composition and coating method thereof, the anti-glare coating prepared by the method has good adhesion, high pencil hardness, and large water contact angle, but its applicable base material is plastic, and the anti-glare coating prepared by the method is plastic. Or metal and other hard-to-adhesive substrates cannot effectively produce anti-glare effect

CN106811108A discloses an anti-glare and anti-flash point coating and its preparation method and application. The invention prepares a high-solid anti-glare UV coating by adding anti-glare particle slurry. The coating has excellent storage stability and anti-glare effect However, the coating is still suitable for plastic substrates and cannot produce anti-glare effects on difficult-to-adhere substrates such as glass or metal

CN106715618A discloses a method for forming an anti-glare coating on a substrate. The method is applied to the surface of the heated substrate in the form of a sol-gel composition, and a sol-gel coating with surface roughness is formed after curing , in order to achieve the anti-glare effect, but before the coating is applied, the substrate needs to be heated, and after the coating is applied, it needs to be further heated and baked to cure, the construction is cumbersome, and the energy consumption is large
