| Name | block polyether amino modified silicone softeners |
| Synonyms | Block polyether amino modified silicone oil softener |
| PH | 4.0~6.0 |
| Physical and Chemical Properties | Light yellow transparent or semi transparent liquid. It does not contain substances prohibited by the European Union and has good self emulsifying performance. With a high solid content, it can give the fabric good smoothness and feel. Its yellowing performance, frost resistance, heat resistance, and stability are better than similar products, and its color change value and dry wet friction fastness are close to advanced products at home and abroad. During the processing and finishing process, there will be no difficult to repair finishing defects such as sticky rolls and silicone oil spots caused by demulsification issues. At the same time, this softener can adapt to poor water quality recycled water and meet the requirements of environmental protection and energy conservation and emission reduction. |
| Use | This product is used for fabric softening and finishing. |
1. Synthesis of Amino Sealing Agent
Firstly, dichloroalkyltetramethyldisiloxane is put into a reactor, replaced with nitrogen, and liquid ammonia is introduced. The reaction is stirred at a certain pressure and temperature to the boiling point, and excess ammonia is removed by reducing pressure. The remaining material is pumped into a distillation kettle for vacuum distillation to extract the amino sealing agent.
2. Synthesis of siloxane segments
Put octamethylcyclotetrasiloxane (D4), amino capping agent, and potassium hydroxide into the reaction kettle, replace them with nitrogen, stir and raise the temperature. After the reaction is completed, lower the temperature, and neutralize and filter the siloxane chain segments with a small amount of acetic acid
3. Synthesis of Double Epoxy Terminated Polyether
Put the terminated hydroxyl polyether and epichlorohydrin into the reaction kettle, stir and raise the temperature. After the reaction is completed, lower the temperature, neutralize with sodium hydroxide, and filter the double epoxy terminated polyether.
4. Preparation of Organic Silicon Finishing Agent by Block Polymerization
Put the siloxane chain segment and double epoxy terminated polyether into the reaction kettle, replace them with nitrogen, add catalyst and solvent, stir and raise the temperature. After the reaction is completed, lower the temperature, adjust it to the specified pH range with acetic acid, and filter to obtain the finished product.
