Waterborne acrylic emulsion process introduction:
Preparation of water-based acrylic emulsion: Add all acrylic monomers, emulsifiers, and water in the raw materials including acrylic hard monomers, acrylic soft monomers, and acrylic functional monomers to the Jinzong emulsification kettle to emulsify them. Obtain a non-stratified emulsion; then add the remaining water, remaining emulsifier, and buffer to the Jinzong polymerization reactor, warm up, add the emulsion, add the initiator to react, and drop the remaining The emulsion and the remaining initiator are dripped after the set time; then the Jinzong polymerization reactor is heated to a certain temperature to keep the reaction warm, and the temperature is reduced to a certain temperature. A pH adjuster is added to adjust the pH of the reaction system to 6-7. The waterborne acrylic emulsion is prepared.
