Abstract

The invention relates to the field of coatings, and concretely discloses an aqueous sterilizing and blue light resisting coating for tempered glass screen protectors, and a preparation method thereof. The aqueous sterilizing and blue light resisting coating for tempered glass screen protectors comprises, by mass, 15-30 parts of nanometer glass resin, 10-30 parts of an aqueous hydroxy acrylic emulsion, 5-20 parts of amino resin, 1-5 parts of organic silicone powder, 0.1-3 parts of a colorful pigment, 0.1-1 part of colloidal silica, 1-5 parts of nanometer barium sulfate, 0.05-0.5 part of nanometer zinc oxide, 0.1-0.2 part of a pH adjusting agent, 0.3-0.5 part of a dispersant, 0.1-0.2 part of an antifoaming agent, 0.05-0.5 part of a blue light absorbent, 2-5 parts of a film filming aid, 0.3-0.5 part of a substrate wetting agent, 0.5-1.0 part of a thickener and 5-10 parts of deionized water. The content of VOCs in the aqueous sterilizing and blue light resisting coating for tempered glass screen protectors is not more than 30 g / L, and the aqueous sterilizing and blue light resisting coating for tempered glass screen protectors has the advantages of high hardness, strong adhesion, good resistance to water, an alkali, stains and weather, self-cleaning property, good scrub resistance, blue light absorption, and lasting and mild sterilization function.

Description

technical field [0001] The invention belongs to the field of coatings, in particular to a water-based bactericidal anti-blue light coating for tempered film and a preparation method thereof. Background technique [0002] The world's top optical experts unanimously pointed out that short-wave blue light has extremely high energy and can penetrate the lens to reach the retina. Blue light irradiating the retina will produce free radicals, and these free radicals will lead to the death of retinal pigment epithelial cells, and the death of epithelial cells will cause light-sensitive cells to lack nutrients and cause vision damage, and these damages are irreversible. Taking the common LED displays on the market as an example, high-energy blue light is mainly concentrated in the wavelength range of 380-460nm. In today's era of rapid technological development, digital products such as computers, notebooks, tablets, and mobile phones can no longer be separated, and people can work, ...
