Embodiment Construction

[0025] Take 600-650g of tea seeds and grind them in a crusher for 40-50 minutes to obtain tea seed powder, soak tea seed powder with 500-600mL of n-hexane, stir for 30-45 minutes, soak for 3-4 hours, filter and remove filter residue to obtain leaching liquid, Pour the leaching solution into the extraction container, extract and wash 3 to 5 times with 400 to 500 mL of water for each wash to obtain crude oil, place the crude oil in an evaporation device, heat up to 70 to 80°C, evaporate for 2 to 3 hours, remove Distill the liquid to obtain the tea seed extract; add 70 to 80 parts of the tea seed extract, 20 to 25 parts of formic acid solution with a mass fraction of 25%, and 10-12 parts of hydrogen peroxide with a mass fraction of 20% and 20-30 parts of a sulfuric acid solution with a mass fraction of 65%, heat up to 80-85°C, start the agitator, stir at a speed of 300-350r / min, and react for 2- After 3 hours, the reaction product was obtained; the reaction product was transferre...

Abstract

The invention discloses an anti-reflection film coating liquid preparation method and belongs to the technical field of film coating liquid preparation. A tea seed extracting solution of the preparation method disclosed by the invention contains rich oxidized antibacterial substances; permanent electrostatic fields exist at the peripheries of added tourmaline particles, so that metal is preventedfrom being oxidized, electrons are prevented from being taken away, and the metal is prevented from being corroded; thus, the film coating liquid has certain salt spray resistance. The tea seed extracting solution in the preparation method disclosed by the invention is subjected to oxidizing treatment, so that the surface of the tea seed extracting solution carries many hydrophilic groups. Tea saponin in the tea seed extracting solution of the preparation method disclosed by the invention is a main green natural non-ionic surface active agent and is also called as theasaponin, oil and water can be separated on the surface of a film coating matrix, and a good cleaning effect on a film layer is generated. By means of the film coating liquid disclosed by the invention, a titanium dioxide / vanadium dioxide composite membrane layer can be formed; a vanadium dioxide crystal layer can obstruct high-energy infrared light, and titanium dioxide can improve transmittance of a film layer to visiblelight; thus, light transmittance characteristic is enhanced, the film layer has a temperature adjusting capacity when applied to glass, and the film layer has a wide application prospect.

Description

technical field [0001] The invention discloses a method for preparing an anti-reflective coating solution, which belongs to the technical field of coating solution preparation. Background technique [0002] Coating solution is a product that can be widely used in automobiles, construction, mobile phones and other fields, and the service life of the product can be effectively extended through appropriate chemical means. However, the film layer applied by the coating solution often has poor adhesion to the material, is easy to peel off, and is difficult to self-repair, resulting in a shortened service life of the product. [0003] With the improvement of environmental protection awareness, the market demand for antibacterial glass is increasing day by day, and the current antibacterial glass is mainly realized by using coating solution. The current antibacterial coating solution is mainly realized by the sol-gel coating technology in colloid chemistry, and a small part is thr...
