Amino resin modified novolac epoxy resin, preparation method thereof and solvent-free high-temperature-resistant coating

The invention relates to the field of coating materials, in particular to amino resin modified novolac epoxy resin, a preparation method thereof and a solvent-free high-temperature-resistant coating. The amino resin modified novolac epoxy resin disclosed by the invention is small in viscosity, an organic solvent does not need to be added when the amino resin modified novolac epoxy resin is used as film-forming resin, and the prepared solvent-free high-temperature-resistant anticorrosive paint can be cured at normal temperature during use. In addition, a coating adopting the amino resin modified novolac epoxy resin disclosed by the invention as film-forming resin has the characteristics of good flexibility, salt mist resistance, seawater resistance, acid and alkali resistance, humidity and heat resistance and excellent high temperature resistance; the coating can be applied to the fields of automobiles, ships, aviation, industrial equipment and the like, such as high-temperature-resistant anti-corrosion protec
