Example Embodiment
[0030] Example 1
[0031] Preparation, formulation (mass percent) of the present invention: isomeric alcohol polyoxyethylene ether non ionic surfactant Antarox EP26 (EP26, purchased from Soli, the following) 20%; fat alcohol polyoxia Vinyl ether high molecular emulsifier N-300 (referred to as N-300, purchased from Shantou Daqian High-tech Research Center Co., Ltd., the following) 40%; antifreeze propanol 5%; complexing agent EDTA-ammonium salt 1%; Deion water is 100%.
[0032] The preparation method is to remove ionized water according to the formulation, and the reaction kettle is heated to 40 ° C to 50 ° C, and the complexing agent EDTA-ammonium brownzoate, antifreeze glycerol and functional polymer are added to the formulation ratio in the case of constant agitation. The auxiliary agent N-300; mixed with EP26 after stirring, continued to stir mix and mix, and the reaction cooled to room temperature 25-30 ° C, the product is a synergistic composition.
