Problems solved by technology

[0010] It can be seen that when an amine curing agent or a phenolic resin curing agent is used, during the curing process, the ring-opening reaction of the epoxy group generates secondary alcoholic hydroxyl groups, and the generation of secondary alcoholic hydroxyl groups will increase the polar groups of the molecular structure, thereby The dielectric rate and water absorption rate of the material are both high, which will result in poor dielectric properties of the plate and cannot meet the requirements of high-frequency operation signals.
