Abstract

The invention discloses an acrylate emulsion for the high-gloss water-based finish varnish with a lotus leaf effect and a preparation method of the acrylate emulsion. The acrylate emulsion is composedof the following raw materials in parts by weight: 20-30 parts of methyl methacrylate, 10-20 parts of isooctyl acrylate, 0.1-3 parts of cross-linking monomers, 1-3 parts of carboxyl monomers, 1-3 parts of organic silicon monomers, 1.1-3 parts of an emulsifier, 0.2-1 part of an initiator, 1-5 parts of a coalescing agent, 0.5-5.5 parts of a pH regulator and 50-65 parts of deionized water. Through aproper core-shell ratio, Tg difference, complete hydrophobicity of a hard core and relative hydrophobicity of a soft shell, a paint film is provided with a structure of ''lotus leaf effect'', and useof inorganic compounds is completely avoided, so that the finish varnish prepared from the emulsion has excellent water resistance, stain resistance, yellowing resistance, stability and universality.

Description

technical field [0001] The invention relates to the technical field of organic polymer polymerization, in particular to an acrylate emulsion for high-gloss water-based finish varnish with lotus leaf effect and a preparation method thereof. Background technique [0002] In recent years, with the development of technology and the improvement of living standards, people's requirements for architectural coatings for exterior walls have become more and more stringent, not only to meet the needs of use, but also to further improve the coatings while controlling costs. All aspects of performance, such as simpler and more convenient construction, more natural and harmonious color, longer service life, better water resistance, easier cleaning and cleaning of surface dust and dirt, etc. The exterior wall coating represented by real stone paint and colorful paint is very popular among users because of its beautiful appearance, natural color, and three-dimensional effect. However, real ...
