Problems solved by technology

At present, there are some anti-blue light coatings for micro-coating on the market, or the amount of anti-blue light pigment is very high, which can meet the requirements of anti-blue light effect, but the transparency is not enough, which will cause damage to the eyes, high haze, and poor sensory. Conforms to industry standards, and is not conducive to reducing the cost of micro-coating and the cost of anti-blue light protective film, or has a low amount of anti-blue light pigment, and the transparency and haze meet the requirements, but the blue light blocking rate is far from the standard
None of these coatings provide a balance of clarity, haze, and blue light blocking

Abstract

The invention discloses an anti-blue-light coating for trace coating. The anti-blue-light coating comprises resin, a solvent, a pigment and a curing agent; the mass of the solvent is equivalent to 90-95 times of the mass of the resin; the mass of the anti-blue light pigment is equivalent to 20-40% of the mass of the resin, and the mass of the curing agent is equivalent to 2-7% of the mass of the resin; the mass of the anti-blue light pigment accounts for 0.3-0.4% of the total mass of the coating; and the resin is polyester resin containing hydroxyl-terminated functional groups. On the premise that the solid content and the use amount of the anti-blue light pigment are greatly reduced, the blue-light-resistant coating disclosed by the invention can keep excellent blue-light-resistant performance, the cost is effectively reduced, the economical efficiency and the environmental protection property are improved, and the blue-light-resistant coating has wide prospects and social requirements.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to an anti-blue light coating for micro-coating of polyester films. Background technique [0002] With the development of science and technology, mobile phones, computers, and tablets have gradually become indispensable necessities in human life. While the rapid development of electronic products is enriching human life, it is also causing irreversible damage to human health, especially the human mind. Windows - eyes. In this case, anti-blue light protective film came into being, among which big brands such as JZT and AP are mainly committed to the research and development of anti-blue light protective film. At present, one of the mainstream preparation processes for anti-blue light protective film is to coat the substrate with anti-blue light coating to form an anti-blue light coating, so as to achieve the effect of preventing blue light. Due to the complexity and limitations of...
