Embodiment 1

[0014] A biological antistatic agent, by weight percentage, comprises 28% emulsifier sorbitol monostearate, 25% by mass percentage is 4% potassium hydroxide solution, 33% ethylene oxide, 5% % EDTA, 2% citric acid, 6% water, 1% 2-methyl-4-isothiazolin-3-one. Among them, water is preferably deionized water. In this embodiment, the commercially available Span S-60 is selected.

[0015] Its preparation method comprises the following steps,

[0016] Step 1, add emulsifier S-60 into the tetrafluoro reactor to heat and melt, start stirring, add potassium hydroxide solution with a mass percentage of 4% into the reactor, heat up, vacuum dehydrate, press nitrogen to remove air and water vapor, the temperature When it reaches 197°C, add 33% ethylene oxide, control the pressure below 0.3MPa, and react for 120 minutes;

[0017] Step 2: Sampling and testing. When the turbidity point of 1% active substance in 10% brine is 68°C, the reaction is over, cool to 65°C, and add citric acid to ad...
