Preparation method and application of self-repairing microcapsule and liquid type blue-light-resistant optical coating

[0037] A method for preparing a liquid-type self-repairing anti-blue light optical coating. Firstly, submicron or micron-sized microcapsules are prepared, and the microcapsules play the role of self-repairing.

[0038] The preparation method of the self-healing microcapsules of the submicron or micron order is:

[0039] The raw materials for the preparation of self-healing microcapsules are as follows:

[0040] Ammonium chloride 0.5g

[0041] Resorcinol 0.5g

[0042] Urea 3g

[0043] Sodium alkylamide ethylene sulfonate 2g

[0044] n-Butyl Phthalate 20ml

[0045] Cetyl Alcohol 0.2g

[0046] Step 1. Add ammonium chloride, resorcinol, urea, and emulsifier into 500ml of water, and stir for 1 hour.

[0047] Step 2. Then add liquid self-healing agent, stabilizer and stir emulsification for 10 minutes, transfer it into a 700W ultrasonic instrument with mechanical stirring function, ultrasonicate at 20% power and stir for 3 minutes.

[0048] Step 3. Finally, add 30ml of 37wt% for
