MANUFACTURING METHOD FOR PHENOL-TRIAZINE COPOLYMER RESIN

摘要

The present invention relates to a method for producing phenol-triazine copolymer resin comprising: a step of making phenol compound, p triazine compound and p aldehyde compound react in the presence of an acidic catalyst under 100°C; and a step of maintaining condensation removal process within the temperature range of 120- 160°C for 1-3 hours, producing homogeneous phenol-triazine copolymer resin with large bonding force between phenol and melamine.
