Embodiment 1

[0035] The first step, preparation of quantum dot colloid aqueous dispersion

[0036] (1) Preparation of oil-soluble fluorescent quantum dots

[0037] a. Preparation of anion precursor complex: add selenium powder and sulfur powder to 2ml trioctylphosphine oxide, stir and dissolve at 25°C to obtain anion precursor complex mixture;

[0038]b. Preparation of cationic precursor complex: Add cadmium oxide and zinc acetate to 10ml of ODE, then add 3ml of oleic acid, then place the system under inert gas, then heat to 160°C and keep heating for 40 min Until the color of the solution is light yellow, cool down to 80°C and vacuumize the system for 30 to remove the moisture in the system;

[0039] c. Heat the obtained cation precursor complex to a reaction temperature of 320 °C. When the temperature reaches the preset temperature, quickly inject the anion and its body mixture obtained in step 1) using a syringe, and then adjust the temperature to 310 °C to keep the reaction for 10 mi...

Abstract

The invention provides colored-light waterborne functional paint applicable to indoor entertainment as well as a preparation method and application thereof and belongs to the technical field of paint,aiming at the problem of an additive of existing functional paint has influences on the performance of the paint. The colored-light waterborne functional paint is prepared by uniformly mixing a colloid water dispersion solution of red, yellow and green quantum dots having high fluorescence quantum efficiency with paint raw materials according to a certain ratio, wherein the raw materials comprise25 to 75 percent of emulsion, 15 to 70 percent of a fluorescence quantum dot colloid water dispersion solution, 0.05 to 0.1 percent of a preservative, 12 to 20 percent of other paint auxiliary agentsand the balance of water. According to the colored-light waterborne functional paint provided by the invention, a quantum dot material is a high-fluorescence material, so that the paint can have a colored-light optical property. The paint is applied on an indoor entertainment place and a wall surface can have a red, green and blue colorful effect under a common illumination condition or under theirradiation of a laser device with safe wavelength. The paint is suitable for being applied on rooms needing entertainment atmospheres, such as schools, houses, offices and restaurants, so that the rooms are very entertaining.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a colored light water-based functional coating suitable for indoor entertainment and its preparation method and application. Background technique [0002] As a decorative material, paint is widely used in the surface interface of industry and life. Based on its chemical interface characteristics, surface interfaces in different fields require coatings with different components and functions. With the continuous development of material technology, the development of functional coatings has made great progress, and the corresponding needs have also been met. [0003] In the application of indoor walls, the coating of paint plays the role of protecting and beautifying the wall, and some places have given more functions to the paint. For example, the walls of teaching places developed in recent years have writable functions, which can replace The projection screen can ...
