Embodiment 1

[0032] Prepare LED electronic display screen self-cleaning cleaning agent 1 according to the following method:

[0033] 1) Prepare Enteromorpha extract:

[0034] Step 1. Dry the fresh Enteromorpha, break it into 60-mesh powder, add 10 times the weight of Enteromorpha powder in an aqueous ethanol solution with a mass fraction of 50%, perform ultrasonic extraction at a temperature of 80°C for 4 hours, and then centrifuge and suction filter. Obtain filtrate, centrifugal condition is 3000r / min, centrifugal 10min;

[0035] Step 2. Put the filtrate in a vacuum rotary evaporator, distill under reduced pressure at 45°C to recover ethanol, and when no more ethanol is distilled out, keep the remaining liquid;

[0036] Step 3, fractionating the remaining liquid in step 2, and collecting the effluent at a temperature of 93°C;

[0037] 2) Weigh 3 parts of 2-10nm rutile nano-TiO2 powder purchased from York Company in the United States, 12 parts of Enteromorpha extract, 12 parts of citric ...

Embodiment 2

[0039] Prepare LED electronic display screen self-cleaning cleaning agent 2 according to the following method:
