Abstract

The invention provides an acrylate emulsion for building interior wall paint and a preparation method thereof, and paint, and belongs to the technical field of building paint. The emulsion is preparedfrom the following raw materials, by weight: 6-20 parts of butyl acrylate, 15.5-26 parts of styrene, 6-20 parts of 2-ethylhexyl acrylate, 0.11-0.55 part of a self-crosslinking monomer, 0.15-1.3 partsof acrylamide, 0.2-3 parts of a carboxyl monomer, 0.015-0.12 part of a silane coupling agent, 0.21-0.81 part of a reactive anionic emulsifier, 0.21-0.81 part of a reactive non-ionic emulsifier, 0.1-2parts of polyethyleneimine, 0.1-0.2 part of adipic dihydrazide, 0.12-0.45 part of persulfate, 0.2-2 parts of ammonia water, and 30-60 parts of water. The emulsion is mainly used for building interiorwall paint; the emulsion can have low MFFT without adding a film forming auxiliary; and the paint prepared by the emulsion can have excellent scrubbing resistance and freeze-thaw stability, and is low in VOC content and excellent in environmental protection.

Description

technical field [0001] The invention relates to the technical field of architectural coatings, in particular to an acrylic ester emulsion for architectural interior wall coatings, a preparation method thereof and coatings. Background technique [0002] Due to its good environmental protection, low cost and excellent performance, water-based acrylate emulsion has become the mainstream resin for architectural interior wall coatings. For architectural interior wall coatings, scrub resistance, freeze-thaw stability, etc. are important performance indicators, and the most important factor affecting these indicators is the selected emulsion. In traditional methods, in order to improve the freeze-thaw stability of coatings, nonionic surfactants with higher ethoxyl numbers are often added to the emulsion, but this will reduce its scrub resistance. [0003] In addition, the minimum film forming temperature (MFFT) of the emulsion for coatings is also an important indicator for consid...
