Problems solved by technology

At present, the mainstream primer product on the market is anionic acrylate emulsion, which has good stability after being formulated with primer, and its performance basically meets the requirements of the market under normal circumstances, but in actual construction projects, there are often problems caused by irregular construction. As a result, the maintenance time of the cement base material is not enough, the base material is alkaline or the salt content is too high, and the exterior wall paint is pan-alkaline or blooming, which seriously affects customer satisfaction, and the film-forming primer commonly used in the market cannot be loose The wall base provides reinforcement
[0003] Cationic acrylate emulsion has excellent penetration reinforcement and anti-salt alkali resistance, but because of its unique cationicity, it has certain defects in paint preparation and workability, and cannot be used on the closed primer. Promote application

Abstract

The invention discloses a permeable closed amphoteric emulsion for a primer. The amphoteric emulsion is prepared from the following raw materials in parts by weight: 50 to 110 parts of deionized water; 10-60 parts of styrene, 5 to 20 parts of n-butyl acrylate; 5-20 parts of iso-octyl acrylate, 2-5 parts of an emulsifier, 2-5 parts of glycidyl methacrylate, 2-5 parts of dodecyl methacrylate, 2-5 parts of methyl erucate, 2-5 parts of a cationic monomer, 2-5 parts of an anionic monomer, 0.5-2.5 parts of a crosslinking monomer, 1-5 parts of a hydrophilic monomer and 0.5-2 parts of an initiator. The emulsion is zwitter-ionic amphoteric emulsion for permeable closed primer, and has excellent paint preparation stability, excellent permeation reinforcing performance and salt and alkali flooding resistance.

Description

technical field [0001] The invention relates to an amphoteric emulsion for a penetrating sealing primer and a preparation method thereof, belonging to the field of primer emulsions. Background technique [0002] With the gradual advancement of economic development and urbanization, architectural coatings have gradually become the main material for building interior and exterior wall decoration, and the role of primers has attracted more and more attention. At present, the mainstream primer product on the market is anionic acrylate emulsion, which has good stability after being formulated with primer, and its performance basically meets the requirements of the market under normal circumstances, but in actual construction projects, there are often problems caused by irregular construction. As a result, the maintenance time of the cement base material is not enough, the base material is alkaline or the salt content is too high, and the exterior wall paint is pan-alkaline or blo...
