Abstract

The invention discloses organosilicon-acrylate ester / inorganic nanometer composite emulsion as well as a preparation method and application of the composite emulsion. The composite emulsion consists of 4.0-8.0(wt)% of inorganic nanometer grains and 92-96.0(wt)% of organosilicon-acrylate ester polymers. The preparation method comprises the following steps of (1) preparing polymer-coated inorganic nanometer grain emulsion; (2) adding an acrylate ester monomer to prepare a shell polymer; (3) adding unsaturated organosilicon monomer to obtain organosilicon modified composite emulsion; (4) carrying out chemical degassing; and (5) removing residual monomers and neutralizing to obtain target products. The prepared organosilicon-acrylate ester / inorganic nanometer composite emulsion has good stability and excellent film-forming performance, modifies the thixotropy of a coating system and also has excellent settlement resistance. Water-borne coating prepared by the composite emulsion disclosed by the invention has the advantages of high adhesion force, paint film washing resistance, alkali resistance, paint film strength, surface cleanness and paint film covering force; and the volatile matter content of the coating is very low; the water-borne coating is green and environment-friendly and also has anti-bacterial property and bactericidal property.

Description

technical field

[0001] The invention relates to a water-based, environment-friendly organosilicon-acrylate / inorganic nano composite emulsion and a preparation method thereof, as well as the application of the composite emulsion in exterior wall coatings. Background technique

[0002] With the increasing requirements for environmental protection and the increasingly stringent regulations on VOC emissions in various countries, high-performance, low-pollution water-based emulsion coatings have become the focus of research and application.

[0003] With the rise of modern high-rise buildings, the requirements for water resistance, aging resistance and stain resistance of coatings are getting higher and higher, and coatings are required to have self-cleaning properties. For outdoor decoration and high-rise buildings exposed to the outdoors for a long time, it is hoped that the anti-staining performance, anti-aging performance, self-cleaning performance and comprehensive performan...
