Problems solved by technology

[0004] Due to the addition of non-polymerizable emulsifiers in conventional emulsions, which remain in the emulsion, gaps appear in the film and are incomplete. Therefore, the problems of water resistance, stain resistance and gloss of the film are caused. The electrical properties of the polymer, The optical properties and surface properties are also affected to a certain extent.
In addition, due to the poor compatibility of silicone and acrylate polymers, the two polymers are clearly phase-separated after film formation, and the existence of small molecule emulsifiers makes this incompatibility more prominent, resulting in silicone acrylic Emulsions are more prone to whitening and cracking than pure acrylic emulsions after immersion in water

Abstract

The invention discloses an acrylate emulsion for a waterborne multicolor paint and a production process of the acrylate emulsion. The acrylate emulsion as the main raw material of the waterborne multicolor paint is prepared from the components including water, an emulsifier, an initiator solution I, an initiator solution II and monomers according to the steps of sequentially preparation of the initiators, preparation of emulsifier, preparation of core liquid, preparation of shell liquid, posttreatment and filtering, wherein the monomers comprise methyl methacrylate, butyl acrylate, methacrylic acid, hydroxyethyl methacrylate and polymerizable organosilicon monomers. The water resistance of the waterborne multicolor paint prepared from the acrylate emulsion prepared according to the production process is greatly improved, and therefore the service life of wall surface paints under moist environments is greatly improved; meanwhile, the paint has good performance and relatively high practical effect, and meets the basic requirements of brushing wall surface paints.

Description

technical field [0001] The invention relates to the field of production of main raw materials of coatings with special needs, in particular to an acrylate emulsion with good water resistance for water-based colorful coatings and a production process thereof. Background technique [0002] Due to the structural characteristics of acrylic resin, its water resistance is poor. At the same time, thermoplastic acrylic resin has poor high temperature resistance, high temperature back sticking, low temperature lack of elasticity, and the film becomes brittle. Silicone has good properties such as heat resistance, weather resistance, water resistance, chalking resistance and UV resistance, but the film forming temperature is high and the adhesion is poor. If the two are combined, the performance of the material will be greatly improved and the application will be wider. [0003] Silicones conventionally used in acrylate emulsions are prone to hydrolysis and condensation due to Si-O-C...
