The invention discloses a preparation method of a super-concentrated carboxyl-based ester-based
polymer. The super-concentrated carboxyl-based ester-based
polymer is prepared from the raw materials inparts by
mass: 1.2-2.7 parts of hydrophilic small
monomer for emulsification, 3.3-5.6 parts of hydrophobic small
monomer for emulsification, 16-37 parts of carboxyl small
monomer, 0.05-0.21 parts ofemulsion initiator, 2.1-5.2 parts of initiator a, 3.2-6.5 parts of initiator b, 370-440 parts of small ester-based monomers, 3.7-8.6 parts of a cross-linking agent, 3.5-7.7 parts of flexible small monomers, 19-44 parts of polyether, 0.2-0.8 part of oxidized
graphene, 0.10-0.29 part of a
chain transfer agent, 5-10 parts of a neutralizing agent, 5-10 parts of a pH
regulator, 2.0-5.0 parts of co-emulsifier, 0.4-1.0 part of liquid film
enhancer and the balance of water, the total raw materials is 1,000 parts, and the
solid content is 50%. The hydrophobic monomers are adopted to prepare the polymeremulsion with excellent water resisting property. The emulsifier is self-made super-concentrated emulsifier, the generation of bubbles during the reaction is reduced, and the initiators with different
initiation efficiency are adopted to stabilize the
reaction rate. The polyether is added in the preparation method, and the
polymer emulsion is enabled to have better connection property, and further has a good repairing effect as a waterproof
coating.
