Abstract

The invention discloses anti-reflection anti-dazzle liquid for an LED glass lampshade and a preparation method of the anti-reflection anti-dazzle liquid, belonging to the technical field of glass dazzle prevention. The anti-reflection anti-dazzle liquid for the LED glass lampshade is prepared by compounding silica nano-sol and micron-order silica emulsion. The method comprises the following steps: dispersing a silicate ester in an organic solvent, adding 0.1-0.3N of alkaline solution, stirring and reacting for at least 24 hours while controlling the temperature to be 20 DEG C below zero to 25 DEG C, and performing rotary evaporation on the reaction solution after the reaction, thereby obtaining the silica nano-sol; dispersing the micron-order silica particles in the organic solvent, adding 0.5-1g of an organosilicon surfactant, and mechanically stirring, thereby obtaining the micron-order silica emulsion; adding the prepared micron-order silica emulsion into the silica nano-sol, stirring, and reacting, thereby obtaining the uniformly dispersed anti-reflection anti-dazzle liquid for the LED glass lampshade. The anti-dazzle liquid disclosed by the invention can bear high temperature, and the LED glass lampshade treated by utilizing the anti-dazzle liquid is fine in surface structure, high in yield, low in light loss, uniform in light transmission and high in light transmittance.

Description

technical field [0001] The invention relates to the technical field of anti-glare glass, in particular to an anti-reflection anti-glare liquid for LED glass lampshades and a preparation method thereof. Background technique [0002] At present, the glass anti-glare technology mainly adopts the optical scattering method. The main principle of this method is to form an irregular concave-convex structure on the glass surface, and the geometric size of the concave-convex structure is much larger than the wavelength of light. When the light is incident on the glass surface, it is diffusely reflected in various directions by these concave-convex structures without forming a specular reflection, so the reflected light intensity is evenly dispersed, and no strong reflection in a single direction is formed, thereby avoiding the glare phenomenon. This method does not change the reflectivity of the glass, only the direction in which light is reflected. There are two main methods for pr...
