AI Technical Summary

Technical Problem

Existing eyeglass lenses cannot effectively protect against both blue light and microwave radiation at the same time, and their water and stain resistance is insufficient, resulting in weak interlayer bonding. They are prone to peeling during long-term use, affecting their service life and safety.

Method used

It adopts a three-layer structure design, including a blue light blocking layer, a water-resistant and anti-fouling layer, and a microwave radiation blocking layer. Through a special synergistic relationship, the interfaces are well bonded. The blue light blocking layer is a hydrothermally synthesized chromium MOF structure on the surface of burr-like silica powder, the water-resistant and anti-fouling layer is a polymer network, and the microwave radiation blocking layer is a ZIF-8/iron oxide composite fiber, forming a continuous magnetic and electrical conductive path.

Benefits of technology

It achieves excellent protection against microwave radiation and blue light, prevents rainwater from adhering, enhances interlayer bonding, and improves service life and safety.

Abstract

The invention discloses an anti-microwave-radiation and anti-blue-light spectacle lens and a preparation method thereof, and belongs to the technical field of optical lenses, the anti-microwave-radiation and anti-blue-light spectacle lens is structurally divided into three layers, namely an anti-blue-light layer, a water-resistant antifouling layer and an anti-microwave-radiation layer from bottom to top in sequence, through a special synergistic relationship among the three layers, the interface bonding is good, and the anti-microwave-radiation and anti-blue-light spectacle lens is not easy to peel off; in addition, good microwave radiation prevention and blue light prevention effects are achieved, oil contamination can be prevented, adhesion of rainwater can be avoided when the waterproof and anti-glare film is used in rainy days, and the sight is prevented from being influenced; the prepared antifouling layer contains pyridine groups, the pyridine groups and cobalt metal ions of the ZIF-8 / ferric oxide composite fibers in the microwave radiation prevention layer can easily form coordinate bonds, pyridine group doping is formed, the dielectric loss angle tangent of ZIF-8 is low, and the consumption efficiency of microwave electric field energy is limited. The doping coordination of pyridine groups can promote the formation of active sites, enhance dipole polarization and interface polarization, and improve the microwave radiation resistance of the microwave radiation resistance layer.
