Embodiment 1
[0024] (1) Preparation of boron modified phenolic resin adhesive
[0025] The boron modified phenolic resin adhesive is made from the following raw materials by weight: 90 parts by weight of phenol, 20 parts of formaldehyde, 5 parts of zinc borate, 3 parts of barium hydroxide, 2 parts of aniline, A151 silane coupling 2 parts of EVA agent, 4 parts of tackifying resin EVA; 90 parts of phenol, 5 parts of formaldehyde and 5 parts of zinc borate were added to the reaction kettle, and 3 parts of barium hydroxide and 2 parts of aniline were added to the reaction kettle while stirring as a composite catalyst. Stir for 15 minutes; then raise the temperature of the reactor to 75°C and react for 50 minutes; then raise the temperature to 85°C, add the remaining part of formaldehyde, and react for 20 minutes; then stop heating, adjust the pH value in the reactor to neutral with oxalic acid, and wait for the reaction When the temperature in the kettle drops below 40°C, add 2 parts of A151 s...
