The application provides a kind of addition type bonding glue with chemical resistance and its preparation method and application.The addition type bonding glue includes silicone composition and modified filler;The silicone composition includes 4-amino-3,5-difluorophenol modified tackifying MQ resin, vinyl silicone oil, hydrogen-containing silicone oil, catalyst and inhibitor;The modified filler is obtained by the reaction of coupling agent and filler after.The application modifies MQ resin by 4-amino-3,5-difluorophenol, introduces C-F bond, C-F bond has large bond energy, thereby gives the excellent stability of bonding glue.Meanwhile, C-F bond has low surface energy, thereby gives the excellent chemical resistance and corrosion resistance of bonding glue such as oil repellency.Secondly, modified tackifying MQ resin has electron-donating ability amino, can further improve the bonding strength of bonding glue, and its chemical resistance.
