  • Patent number: 11608348
    Abstract: A preparation method of functional silanes comprises: substance A and substance B are added in a three-necked bottle and a certain amount of solvent is added; the resultant mixture is stirred for 0.5-24 h in the presence of catalyst under an atmosphere of argon, resulting in the crude product; after removing the remaining solvent and catalyst, the residual product is purified by chromatographic column to obtain functional silanes; the substance A is an alkene-containing silane and the substance B is an alcohol; functional silanes with various structures can be prepared, and their structures can be controlled by regulating the ratio of substance A and substance B, thereby providing ideas for the preparation of different silanes and the structural design of silane coupling agents.

  • Patent number: 11319447
    Abstract: The invention presents a preparation method of organic silicone elastomers cross-linked bypolyphenols, which comprises steps as follows: (1) Dissolve 15-250 parts (by mass) of amino-polysiloxanes in the organic solvents to get the amino-polysiloxanes solution; then, dissolve 1˜20 parts of polyphenols in 1-60 parts of water to get the aqueous solution of polyphenols; mix the said two solutions, add 2-130 parts of reinforcement fillers, stir evenly, and then pour them into the mold. (2) Cure and cross-link the mold containing the mixed solutions at 80° C.-170° C. for a period of time, and cool it to room temperature to get the organic silicone elastomer.
