Problems solved by technology

Although the output of light-curing coatings in my country has ranked among the top in the world, overall, the product technology content is low and the added value is not high. Many resin materials and additives mainly rely on imports.

Embodiment 2

[0029] This implementation 2 is changed on the basis of Example 1. Specifically, the content of each component of the UV-cured superhydrophobic anti-fingerprint coating is different. The content of each component of the coating by mass percentage is: polyurethane acrylate resin 36.5%, 12% acrylate resin, 4% active fluorine monomer, 8% silicone resin, 3% modified nano-silica, 6% reactive diluent, 0.5% photoinitiator, and 30% additives.

Embodiment 3

[0031] This implementation 3 is changed on the basis of Example 1. Specifically, the content of each component of the UV-cured superhydrophobic anti-fingerprint coating is different. The content of each component of the coating by mass percentage is: polyurethane acrylate resin 50.45%, 10% acrylate resin, 0.5% active fluorine monomer, 5% silicone resin, 1% modified nano-silica, 5% reactive diluent, 0.05% photoinitiator, and 28% additives.

Abstract

The invention discloses an ultraviolet (UV) curable super-hydrophobic anti-fingerprint coating, which consists of a polyurethane acrylate (PUA) resin, an acrylic ester resin, an activated fluorine monomer, a silicon resin and modified nano SiO2. The UV curable coating consists of a PUA oligomer, an activated thinner, a photoinitiator and an additive. According to the UV curable super-hydrophobic anti-fingerprint coating, the UV curable coating is prepared from the high-activity PUA oligomer, the activated thinner, the photoinitiator and the like, and a monomer with a special structure is added to resist fingerprint impressions; on such a basis, the activated fluorine monomer, the silicon resin and the like are introduced to form surface-dense and stable self-demixing hydrophobic varnish, so that a self-cleaning effect is achieved; and the modified nano SiO2 is used for constructing a surface micro / nanostructure by adopting a self-assembly technology, so that the UV curable super-hydrophobic anti-fingerprint coating has high performance. The invention also discloses a preparation method for the UV curable super-hydrophobic anti-fingerprint coating.

Description

technical field [0001] The invention relates to a UV-cured coating, in particular to a UV-cured super-hydrophobic anti-fingerprint coating and a preparation method thereof. Background technique [0002] UV curable super-hydrophobic and anti-fingerprint coatings can truly be called "5E" type environmental protection coatings because of their technical, economical and ecological advantages. It is expected that the scope of application will be extremely wide, the growth rate will be extremely fast, and it will gradually penetrate into the special coatings industry. Some varieties of traditional coatings (such as epoxy, chlorinated rubber, etc.) have good protective performance but poor decorative performance, while some varieties (such as nitro paint) have good decorative performance but poor protective performance. However, polyurethane coatings combine protective and decorative properties with a high degree of mechanical wear resistance and toughness, and can be used in a wi...
