Embodiment 1
[0010] Add 90g of water, 38g of sodium sulfite, and 60g (37%) of formaldehyde into a 2000ml reactor, stir at room temperature for 40min, add 11.2g of sodium hydroxide (47%), and 376g of phenol; heat up and reflux for 60min, then cool down to 60°C, and add formaldehyde 748g (37%), heat up to 80°C for constant temperature reaction, and control the curing time at 5-7min / 130°C. Immediately lower the temperature to below 40°C and discharge to make a thermosetting resin.
Embodiment 2
[0012] In 2000ml reactor, add 90g water, 22g sodium sulfite, 18g sodium bisulfite, 67g (37%) formaldehyde, stir 40min at normal temperature, add sodium hydroxide 21g (47%), phenol 420g, heat up and reflux after 50min and cool down to At 60°C, add 845g (37%) of formaldehyde, raise the temperature to 80°C for constant temperature reaction, and control the curing time at 5-7min / 130°C. Immediately lower the temperature to below 40°C and discharge to make a thermosetting resin.
Embodiment 3
[0014] Add 90g of water, 52g of sodium metabisulfite, and 75g (37%) of formaldehyde into a 2000ml reactor, stir at room temperature for 60min, add 21g of sodium hydroxide (47%), 420g of phenol, heat up and reflux for 50min, then cool down to 60°C, add formaldehyde 809g (37%), heat up to 80°C for constant temperature reaction, and control the curing time at 5-7min / 130°C. Immediately lower the temperature to below 40°C and discharge to make a thermosetting resin.
