| titleOfInvention | High-flash-point quaternized polyether block silicone oil and preparation method thereof |
| abstract | The invention provides a preparation method of high-flash-point quaternized polyether block silicone oil, which adopts epoxy polyether silicone oil and tertiary amine polyether as raw materials, adopts a high-flash-point alcohol solvent as a solubilizer, can replace low-flash-point isopropanol to carry out amination ring-opening reaction, and obtains polyether polysiloxane copolymer silicone oil with a terminal quaternary ammonium salt structure by a one-step method. The high flash point solubilizer selects alcohol/ether solvent with stronger dissolving capacity, and the structure of the solubilizer contains lipophilic alkyl chain segments and hydrophilic hydroxyl/ether chain segments, so that the solubilizer can dissolve hydrophobic organic silicon compounds and hydrophilic tertiary amine polyether. |
