Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a preparation method of an ultra-concentrated carboxyl ester-based emulsion polymer waterproof coating. Background technique [0002] Waterproof coatings are solvent-based, water-based coatings made of synthetic polymers, polymers and asphalt, polymers and cement as the main film-forming substances, adding various additives, modified materials, filling materials, etc. Cream or powder coatings. The paint is painted on the roof, basement, toilet, bathroom and exterior walls of buildings and other base surfaces that need to be waterproofed, and can form a continuous, integral paint waterproof layer with a certain thickness under normal temperature conditions. [0003] With the development of the times, China's waterproof market is also changing with each passing day. It has extended and expanded from traditional housing waterproofing to highways, high-speed r...
