Characteristics of water-soluble silicone oil (3)

As a chemical substance, water-soluble silicone oil is inactive under normal conditions and can be stored for a long time. When encountering some strong oxidants or reactive reagents, different products will be produced. For example, when encountering an epoxy reagent, here is an example of the reaction: In a dry three-necked flask, add a certain amount of polyoxyethylene propyl ether, unsaturated glycidyl ether, and toluene as the solvent. Hydrogen-containing silicone oil is added, the reaction temperature is controlled, and nitrogen is protected during the reaction. After the reaction is completed, unreacted substances and solvents are removed, and n-propanol is added as a blocking agent to obtain a pale yellow transparent liquid. This new thing is of great research value.
      Water-soluble silicone oil containing vinyl group silicone oil is a polydimethylsiloxane with a vinyl group at each end of the molecular chain. It is an excellent and lively intermediate material. In addition to smoothness, softness, gloss, temperature and weather resistance, it also has unique properties such as
      1. The vinyl at both ends has a strong reactivity, which can (under the action of a catalyst) quickly react with a hydrogen-containing silicone oil, and can also participate in many other reactions;
      2. Compared with branched-chain vinyl silicone oil, the molecule has no overhanging segments;
      3. It has better compatibility with organic materials than methyl silicone oil and is easier to be compatible with other organic materials;
      4, is the production of silicone rubber base compound, can improve the fluidity, tear resistance and other physical and mechanical properties of silicone rubber;
      5. The hydrophilic side chain of water-soluble silicone oil can be continuously adjusted and improved, which results in modified silicone oils of different compatibility types.
     In short, the application space of water-soluble silicone oil in chemical properties is also very wide.
