Boring density is 109cm-2-107cm-2。
When light is incident on two refractive index different interfaces, it will lead to a part of light and reflect, between this different medium
Reflex becomes Fresnel reflection effect.Fresnel reflection effect refers to since the refraction coefficient of two media is different, leads
It causes refraction coefficient to be in a kind of discrete state at the interface of two media, is reflected so as to cause incident light, therefore, enhancing
Anti-blue light lampshade material surface is to improve the important means of blue light filter effect to the Fresnel reflection effect of blue light.In order to increase
Fresnel reflection effect between strong interface, the interface that can be contacted on the surface of the material with air by science and technology modify one layer
The reflecting layer of refraction coefficient mutation is destroyed to increase interface reflection, can specifically pass through two o'clock：Exist first is that increasing by one layer of refraction coefficient
Reflecting layer between lampshade material and air, increases emergency light reflex, i.e., one of the major technique of current anti-blue light passes through coating technique
Multilayer film production is plated in substrate surface；Second is that by the concave-convex contoured nano-micro structure of lampshade material surface preparation, for indigo plant
Optical band design nano-cone array be equivalent to one reduction refraction coefficient dielectric layer, blue light inside nanometer light trapping structure not
Disconnected ground roundtrip reduces the diverging of blue light, therefore has preferable anti-blue light effect.
Main component of the Nano silica sol as anti-blue light film, particle is colorless and transparent, does not influence the light transmission of lampshade
Property, at the same can dirt-resisting dustproof, the Nano silica sol preferable particle size is 1-50 nanometer, and partial size will affect lampshade greater than 50 nanometers
Translucency, and will cause surface bulge, be unfavorable for the formation of nanocone matrix.
The double pentaerythritol methacrylate is as UV monomer, containing anti-there are six may participate in photocuring in each molecule
The active group answered, curing rate are exceedingly fast, and crosslink density is big, and solidification hardness is high, lampshade can be made to have excellent wear-resisting
Performance.
1- hydroxycyclohexyl phenyl ketone is as photoinitiator of the invention, after receiving UV Absorption, light absorbing energy
Amount, and then cause double pentaerythritol methacrylate and Nano silica sol generation chain polymerization, there is excellent thermal stability, together
When anti-blue light film can be made non-yellowing for a long time.
For polydimethylpolysiloxane compound as levelling agent of the invention, effect is the evaporation rate for adjusting solvent, drop
Low viscosity improves the mobility of liquid coining material, so that liquid coining material is equably covered on the top surface of light-transmitting plate, together
When can be effectively reduced surface tension between liquid coining material and light-transmitting plate, improve filming performance.
The acrylic acid fluorinated ester can make the nano particle in Nano silica sol be distributed more in liquid coining material
Uniformly, the aggregation of nano particle is avoided.
