[0054] Another aspect of the present invention provides a method for preparing an aqueous acrylate emulsion for building exterior walls, which includes the following steps:
[0055] Add deionized water to the flask, add metal-containing compounds and mercaptoglycolic acid, adjust the pH to 10-12, heat and boil under nitrogen, and quickly add the quantization reagent.
[0056] Add initiator to the flask, stir to dissolve with acetone, and after the dissolution is complete, add methyl methacrylate, butyl acrylate, acrylic acid, hydroxyethyl acrylate and mercaptoethanol, heat and stir, condense and reflux, react for 6h-8h, then cool After reaching room temperature, sodium bisulfate and hydroxyisoquinoline were added to the reaction system, the reaction solution was heated to 80°C-100°C, and after reacting for 5 hours, the temperature of the reaction product was cooled to 35-40°C. Add ammonia and triethylamine to adjust the solution to be neutral, stir, add deionized water, and distill...

[0069] Preparation of water-soluble quantum dots:
[0070] Preparation of ZnSe quantum dots. Add 1000ml of ionized water to the round bottom flask, add 20g of ZnC1 after nitrogen gas 2 ·2.5H 2 After dissolving by magnetic stirring, add 8ml mercaptoglycolic acid, adjust the pH to 10 with NaOH (1mol / L) solution, continue to pour in nitrogen, heat to boiling, quickly add the newly prepared NaHSe solution under vigorous stirring, and boil the water to reflux.
[0071] Preparation of NaHSe: Add a small amount of secondary deionized water and 0.04g NaBH to the reaction vessel in sequence 4 ,Magnetic stirring. Wait for NaBH 4 After dissolution, add 0.04g of Se powder under the protection of nitrogen, and react at a constant temperature at 4°C. After standing for a period of time, take the upper layer of NaHSe clear solution.
[0072] Preparation of modified acrylate:
[0073] In a 500ml four-neck flask, add 1.0g of the calculated initiator azobisisobutyronitrile, pour in 100ml of acetone...
