Abstract

The invention discloses a preparation method of a quaternary ammonium salt and quaternary phosphonium salt cationic core-shell emulsion polymer. A cation strong hydrophilic monomer and a benzene ringrigid hydrophobic monomer are used as raw materials, in an emulsification reaction system, a high-molecular polymer waterproof coating is prepared by a series of processes such as dispersion and emulsification, constant-temperature polymerization, pH adjustment and the like. The strong hydrophilic effect enhances the adhesion force with a matrix, the rigid benzene ring provides good mechanical properties and mechanical properties, the film forming hardness and the tensile strength are enhanced, and the cross-linking agent reticular combination effect significantly improves the mechanical properties and adhesion force between polymers. The waterproof coating is more environment-friendly than an oily waterproof coating, has stronger binding force to the cement surface than an anionic waterproof coating, and has a better and more durable waterproof effect; the waterproof coating disclosed by the invention is simple in preparation method, adjustable in viscosity, good in sagging property,convenient for secondary construction and suitable for large-area mechanical construction.

Description

technical field [0001] The invention belongs to the technical field of emulsion polymers, relates to the fields of surface treatment and adhesion coatings, in particular to a method for preparing a quaternary ammonium salt quaternary phosphonium salt cationic core-shell emulsion polymer. Background technique [0002] Nowadays, paints are generally applied on most building materials to avoid erosion of materials. At the same time, many buildings choose waterproof paints with pigments to achieve good waterproof and beautiful appearance. However, most of the paints on the market are waterproof. The performance and aging resistance are generally poor, and the adhesion is average. After a long period of rain, especially acid rain, and ultraviolet radiation, it will crack and fall off. It is not beautiful but also absorbs moisture and reduces the service life of the building. Traditional emulsion Coating polymerization process, not only the process is cumbersome, the final demulsi...
