Abstract

The invention discloses a high-efficiency ytterbium fluoride mixed material and a preparation process thereof, and relates to the technical field of yttrium fluoride mixed materials. The mixed material aims to solve the problems that since most reflective films in the prior art are mainly used for reflecting light, although a certain sun protection function can be achieved, ultraviolet rays in the light cannot be isolated. The mixed material comprises, by weight ratio, 90-97% of ytterbium fluoride and 3-10% of titanium dioxide. Finely ground ilmenite is reacted with sulfuric acid under the conditions of introducing air continuously and carrying out stirring to produce soluble sulfate first, wherein the reaction equation is shown as FeTiO3+H2SO4=TiOSO4+FeSO4+2H2O; finally, when the titanium dioxide is prepared, the prepared titanium sulfide (TiOSO4) is mixed with water to undergo a hydrolysis reaction, and the reaction equation is shown as TiOSO4+2H2O=TiO2 H2O / +H2SO4.

Description

technical field

[0001] The invention relates to the technical field of ytterbium fluoride mixed materials, in particular to an efficient ytterbium fluoride mixed material and a preparation process thereof. Background technique

[0002] Optical thin films are composed of thin layered media, a class of optical media materials that transmit light beams through interfaces. The application of optical films began in the 1930s. In modern times, optical films have been widely used in the field of optics and optoelectronics technology to manufacture various optical instruments; this includes reflective films, which are made by doping HR polymer optical agents and enhancing polymers in PET resins during tape casting. Plastic, to achieve light-shielding and high-reflection film, because the middle layer of the film absorbs light to a certain extent, which reduces the reflection effect. Therefore, a layer of HR dielectric film is added on the surface to achieve better reflection effec...
