Zusammenfassung: | The invention discloses a high temperature resistant modified epoxy resin, a preparation method thereof and use thereof. The high temperature resistant modified epoxy resin is produced by performing a modification reaction of polymethyl silicone and bisphenol A epoxy resin at 100 to 180 DEG C for 8 to 24 hours in the absence of the air. A resin material obtained by curing the modified epoxy by using a common amine curing agent can resist a temperature above 350 DEG C, has a coating adhesive force of 8 to 15MPa and is greatly improved in flexibility and impact resistance. |
