[0025] Example 1:
[0026] The preparation method of the hydrophobic polyquaternium oil antistatic agent of the present invention includes the following steps:
[0027] Step 1: Fully dissolve methacryloxyethyl trimethylammonium chloride, isooctyl acrylate and initiator azobisisobutyronitrile in methanol to form a monomer solution. The weight ratio of methacryloyloxyethyl trimethylammonium chloride, isooctyl acrylate, azobisisobutyronitrile and methanol is 6:28:0.30:30;
[0028] Step 2: Put 40ml petroleum ether into a 500ml four-necked flask equipped with stirring, thermometer, condenser and constant pressure dropping funnel, the weight ratio of petroleum ether to monomer solution is 40:65, stir and heat up to 60℃, After the heating is completed, the monomer solution configured in step 1 is added dropwise;
[0029] Step 3: After the dripping is completed, the temperature is raised to 70°C and the temperature is kept for 4.0 hours;
[0030] Step 4: Pour the reacted solution into cold wa...
