[0017] Preferably, the preparation method of the synergist comprises the following steps:

[0018] Step 1: Take ethanol and deionized water, prepare a mixed solvent in a volume ratio of 1:4, take two portions, each with a volume of 1L, take 100g of magnesium chloride hexahydrate and dissolve it in the first portion of the mixed solvent to obtain a magnesium chloride solution, and take 40g of sodium hydroxide solid and dissolve it in the second portion of the mixed solvent to obtain a sodium hydroxide solution;

[0019] Step 2: Add 2 g of fatty alcohol polyoxyethylene ether to the magnesium chloride solution in step 1, stir well, heat to 75°C, add the sodium hydroxide solution prepared in step 1 at a rate of 20 mL / min, and after the addition is completed, keep the reaction warm for 2 h, stand for 1 h, filter, wash, and dry to obtain magnesium hydroxide solid;
