Abstract

The invention discloses a preparation method of a self-assembled hydrophobic light-reflecting and light-converting material, and belongs to the technical field of light-reflecting and light-convertingmaterials. The preparation method has the advantages that by applying a self-assembly method, directed plasma graft polymerization and other reactions are carried out to form a light-converting layer, then hydrophobic silica is gradually compounded with a light-reflecting layer to form layer-by-layer self-assembled films, formed polymerization layers fit flat, light reflecting can be carried outby relying on a silica layer, and the light is conducted to a silane light-converting layer, which achieves the purposes of light reflecting and light converting and achieves dual signal response andmultiple functions; by adopting the layer-by-layer self-assembly principle, the preparation method is simple, the sources of raw materials are wide, the labor intensity is reduced, the service life ofthe material is prolonged, the material has hydrophobicity, the accumulation of stains and water marks is avoided, and the material can be used in the fields of dual signal materials, optical energyconversion and the like.

Description

technical field [0001] The invention relates to the technical field of light-reflecting and light-converting materials, in particular to a preparation method of self-assembled hydrophobic light-reflecting and light-converting materials. Background technique [0002] Reflective material is a kind of material with reflective properties. Generally, it is made of modified rosin resin or alkyd resin as the base material, and is prepared by adding fillers, additives, aggregates and glass beads. Can be sprayed or brushed on. Used as road markings, signs, etc. For a long time, the reflective material products used in domestic road traffic have low production efficiency, poor retroreflective performance, and poor recognition performance, while reflective light-turning materials have added light-turning and reflective functions on the basis of materials, and can be widely used. It is widely used in agriculture, identifying signals, has great potential for development, and has brigh...
