Embodiment 1
[0044] Add 10g of deionized water, 10g of alcohol ether anionic emulsifier, and 25g of 705#VEA emulsion into the reaction pot in turn, stir well for later use, dissolve 1g of styrene, 20g of isooctyl acrylate, and 24g of n-butyl acrylate in 12g of 210# rosin After the modified phenolic resin is pumped into the high-level tank A, and mixed evenly for later use, 0.1g of ammonium persulfate is completely dissolved in 1g of deionized water and then pumped into the high-level tank B for later use; the above reaction pot is heated up, and when the temperature reaches 78°C, add 5% of the spare monomer mixture in the head tank A, add 20% of the spare ammonium persulfate solution in the head tank B after 8 minutes, keep the temperature at 78°C for 25 minutes, add the remaining monomer mixture in the head tank A within 2 hours After the monomer mixture and 60% of the ammonium persulfate solution in the head tank B are added, the temperature of the reaction vessel is controlled to be 82°C...
Embodiment 2
[0051] Add 17g of deionized water, 4g of alcohol ether anionic emulsifier, and 32g of 705#VEA emulsion into the reaction pot in turn, stir evenly for later use, dissolve 8g of styrene, 5g of isooctyl acrylate, and 30g of n-butyl acrylate in 20g of 210# rosin After the modified phenolic resin is pumped into the high-level tank A, and mixed evenly for later use, 0.7g of ammonium persulfate is completely dissolved in 7g of deionized water and pumped into the high-level tank B for later use; the above reaction pot is heated up, and when the temperature reaches 80°C, add 5% of the spare monomer mixture in the head tank A, after 5 minutes, add 20% of the spare ammonium persulfate solution in the head tank B, keep the temperature at 80°C for 20 minutes, add the remaining monomer mixture in the head tank A within 2.5 hours After the monomer mixture and 60% of the ammonium persulfate solution in the head tank B are added, the temperature of the reaction vessel is controlled to be 84°C; ...
Embodiment 3
[0058] Add 24g of deionized water, 1g of alcohol ether anionic emulsifier, and 39g of 705#VEA emulsion into the reaction pot in turn, stir well for later use, dissolve 15g of styrene, 12g of isooctyl acrylate, and 17g of n-butyl acrylate in 5g of 210# rosin After the modified phenolic resin is pumped into the high-level tank A, and mixed evenly for later use, completely dissolve 1.3g of ammonium persulfate in 13g of deionized water and then pumped into the high-level tank B for later use; heat up the above reaction pot, and add it when the temperature reaches 82°C 5% of the spare monomer mixture in the head tank A, add 20% of the spare ammonium persulfate solution in the head tank B after 8 minutes, keep the temperature at 82°C for 30 minutes, add the remaining monomer mixture in the head tank A within 2.5 hours After the monomer mixture and 60% of the ammonium persulfate solution in the head tank B are added, the temperature of the reaction vessel is controlled to be 84°C; the...
