Organic sillicon modified acrylic ester/inorganic nano composite emulsion and its preparation

Abstract

A composite organosilicon modified acrylatel inorganic nano emulsion features that the nano-class inorganic phase (SiO2, TiO2, ZnO and CaCo3) is contained in the particles of organosilicon modified acrylate emulsion, and is prepared through reverse emulsion polymerizing and in-situ emulsion polymerizing. Its advnatages are high mechanical, self-cleaning and antistatic performance and high stability. It can be used for paint, adhesive, polishing agent and cement modifier.

Description

technical field

[0001] The invention relates to a water-based paint, in particular to an organosilicon-modified acrylate / inorganic nanocomposite emulsion and a preparation method thereof. Background technique

[0002] With the development of high-rise and large-scale modern buildings, people have higher and higher requirements for architectural coatings, especially the requirements for anti-aging, stain resistance and self-cleaning performance of coatings. For exterior wall decorations that are exposed to the outdoors for a long time, outdoor decorations that are difficult to repair, and high-rise buildings, it is hoped that the mechanical properties, anti-staining properties, anti-aging properties, self-cleaning properties and comprehensive properties of the coating will be the best. Silicone-modified acrylate emulsion coatings (silicon-acrylic emulsion coatings for short) can meet the needs in some aspects, but they have deficiencies in anti-agi...
