Preparation of polyether epoxy silicone oil with different molecular weights and properties of hydrophilic silicone oil
8K,10K,13K and 20K hydrogen terminated silicone oils were used to undergo hydrosilylation reactions with allyl epoxy polyether 500 to prepare polyether epoxy silicone oils of different molecular weights.The polyether epoxy silicone oil was then aminated with polyether amine to produce ternary copolymer hydro-philic silicone oil.The application performance from multiple dimensions such as hand feel,hydrophilicity and stability were systematically studied,and the differences between hydrophilic silicone oils prepared from differ-ent molecular weight polyether epoxy silicone oils under the same process conditions were compared.The re-sults showed that the smaller the molecular weight of polyether epoxy silicone oil,the softer the hand feel,the faster the hydrophilicity,and the better the washing resistance.Small molecule polyether epoxy silicone oil was more suitable as a raw material for synthesizing hydrophilic silicone oil.
