The end epoxy polyether silicone oil introduces a hydrophilic polyether segment in the structure. In the subsequent block polymerization, it is not necessary to use the ED series polyether amine, and only the D series polyether amine and fat are used. Amines, alcoholamines and other low-cost organic amines can be used to synthesize block silicone oils, effectively reducing the raw material cost of block silicone oils;
