Abstract

The invention discloses a preparation method of a cationic alkyl hyperconcentrated emulsion polymer for a coating. The polymer is mainly prepared from the following materials: 1.4 to 2.3 parts of a hydrophilic small monomer for emulsification, 4.2 to 5.5 parts of a hydrophobic small monomer for emulsification, 5 to 20 parts of a cationic small monomer, 0.05 to 0.22 part of an emulsion initiator, 3.4 to 6.2 parts of an initiator a, 2.3-4.5 parts of an initiator b, 400-430 parts of an alkyl small monomer, 20-33 parts of a fluorine functional monomer, 4.6-8.4 parts of a cross-linking agent, 0.12-0.31 part of a chain transfer agent, 10-20 parts of a neutralizer, 5-10 parts of a pH regulator, 1.0-3.5 parts of a co-emulsifier and 0.2-0.7 part of a liquid film enhancer, with the balance being water, wherein the total mass part of the components is 1000. According to the invention, the hydrophilic small monomer and the hydrophobic small monomer are subjected to hyperconcentrated emulsion polymerization to form the polymer, and the formed polymer has the same adsorbability as the hydrophilic small monomer and the same waterproofness as the hydrophobic small monomer, so the polymer has superior effect compared with traditional waterproof coating material, and has better waterproof effect and long service life.

Description

technical field [0001] The invention belongs to the technical field of building materials, relates to the field of waterproof materials, in particular to a method for preparing cationic alkyl super-concentrated emulsion polymers for coatings. Background technique [0002] With the continuous increase of new waterproof materials and new processes, as well as the continuous improvement of the application technology of building waterproof materials, the application field of building waterproof materials has gradually expanded from the field of housing construction to expressways and urban roads and bridges, subways and urban rails, and high-speed rails. In infrastructure projects such as railways, airports and water conservancy facilities, the waterproof parts of buildings have also extended from indoors to external walls. The expansion of application scope has also promoted the development of waterproof coatings. [0003] The rapid development of waterproof coatings has become...
