Abstract

A core-shell styrene-acrylic emulsion for primer coatings belongs to the technical field of waterproof coatings, and includes the following components in parts by mass: 5.07-30 parts of core monomers, 5.07-30 parts of shell monomers, 0.6-12 parts of emulsifiers, 0.02-5 parts of initiator, 0.02-5 parts of chain transfer agent, 0.02-5 parts of pH buffer, 0.02-2 parts of first defoamer, 0.02-2 parts of first preservative and 40-50 parts of deionized water; The core monomer is the main monomer, and the shell monomer includes 4.93-20 parts of the main monomer, 0.02-2.55 parts of the polar monomer, 0.02-2.5 parts of the phosphate ester monomer and 0.05-2.5 parts of the urea monomer 5 servings. The present invention also provides the preparation method of the core-shell styrene-acrylic emulsion for the primer coating and the application of the core-shell styrene-acrylic emulsion for the primer coating in the water-based sealing primer coating, and the primer coating made of the core-shell styrene-acrylic emulsion It can not only ensure the film-forming, sealing and adhesion of the paint film, but also make the paint film have higher surface hardness and anti-tearing ability of masking paper.

Description

technical field

[0001] The invention belongs to the technical field of waterproof coatings, and relates to a core-shell styrene-acrylic emulsion for primer coatings and a preparation method and application thereof. Background technique

[0002] Although the current performance of water-based coatings cannot exceed that of traditional solvent-based coatings, it has become an inevitable trend in the development of coatings because of its non-pollution, environmental safety and compliance with national environmental protection policies. In particular, my country promulgated new regulations for the coatings industry at the end of 2014. And after the new regulations came into effect on February 1, 2015, water-based coatings or the water-based coatings have become the key to the sustainable development of enterprises. The original solvent-based coating companies have been gradually eliminated, and many cities have promulgated stricter regulations accordingly. The use of solvent-base...
