Examples
Embodiment 1
[0052] A silicone oil softener, the preparation method is: 120 parts of water, 3 parts of cationic emulsifier, 2 parts of nonionic emulsifier and 16 parts of octamethylcyclotetrasiloxane, 2.5 parts of quaternary ammonium as shown in the aforementioned formula 1 Add the salt siloxane into the reaction vessel, stir and emulsify for 0.5h; raise the temperature to 80-85°C, add 1 part of sodium hydroxide, react for 3h, and then dropwise add the polymerizable quaternary ammonium salt monomer 4 shown in the above formula 2 1 and 0.5 parts of the initiator were added to the reaction vessel and reacted at 75-80°C for 1 hour to obtain a silicone oil softener.
[0053] The cationic emulsifier is lauryl polyoxyethylene ether dimethyl dodecyl ammonium bromide, the nonionic emulsifier is polyoxyethylene ether AEO-9, and the initiator is sodium persulfate.
Embodiment 2
