Embodiment 1
[0026] A high-efficiency cleaning agent for electronic products is made of the following raw materials in parts by weight:
[0027]
[0028] The preparation method of described fluorine-containing amphoteric surfactant, comprises the steps:
[0029] 1) Dissolve 100 g of N-tris(hydroxymethyl)methyl-2-aminoethanesulfonic acid in 400 g of acetonitrile, and add 200 g of 1-bromooctadecane therein, stir and react at 40° C. for 6 hours, and then pass Rotary steaming, washing 5 times with ether, and rotary steaming again to obtain the intermediate product;
[0030] 2) 90 g of the intermediate product prepared in step 1) was dissolved in 150 g of deionized water, and then 45 g of sodium hydroxide and 36 g of tetrabutylammonium bromide were added thereto, and stirred at room temperature for 0.5 hours, and then added 75g of perfluorodecane bromide, reflux and stir at 70°C for 1 hour, cool down after the reaction, extract with dichloromethane, wash 3 times with water, take the organic...
