| titleOfInvention | High molecular weight MQ silicon resin and synthesis method and application thereof |
| abstract | The invention provides high molecular weight MQ silicon resin and a synthesis method and application thereof. The synthesis method of the MQ silicon resin comprises the following steps: pre-reacting silicate ester and partial M unit silane monomer in a mixed solution consisting of water, a catalyst and a cosolvent; adding the rest M unit silane monomer and part of the extractant into the mixture to react under the heating condition, then adding the rest extractant, and extracting to obtain an organic phase; adjusting the organic phase to be neutral, and then distilling to obtain high molecular weight MQ silicon resin; wherein the mass ratio of the M unit silane monomer added twice is 10: 1-1: 10. The method has simple flow, does not need a large amount of water washing, has high product yield, does not need to add an additional remover to eliminate silicon hydroxyl and silicon acyloxy in the MQ silicon resin, and can control the molecular weight of a target product through the proportion of the M monomer added in batches and the proportion of the extracting agent added in batches. |
