Technical progress in the preparation of hydrophilic amino silicone oil
The preparation technology of hydrophilic amino silicone oil has undergone an evolution from the modifi-cation of side chain groups to the modification of main chain groups.The side chain modification mainly includes the prep-aration of side chain epoxy polyether silicone oil by amination,the copolymerization modification of polyether modified ami-no silane coupling agent and linear hydroxyl polysiloxane,the modification of side chain amino silicone oil by epoxy butyl pdyether.With the maturity of main chain block technology,all the modified groups are changed from side chain to main chain branching.The main chain modification mainly includes the preparation of block copolymerization of end-epoxy sili-cone oil with tetramethylbis-tertiary amine,the preparation of block copolymerization of end-epoxy silicone oil with end-tertiary amine polyether amine and end-secondary amine polyether amine,and the preparation of block copolymerization of end-epoxy polyether silicone oil with primary amine polyether amine.The conformational relationships between their struc-tures and application properties are explored,laying the foundation for the subsequent production practice to be able to ac-curately design the corresponding modified silicone structures according to the application properties to be achieved by the fabric.
