Production process of core/shell emulsion for environment-friendly wood coatings

Abstract

The invention discloses a production process of a core / shell emulsion for environment-friendly wood coatings. A core / shell polymerization technology is adopted, so that the aims of reducing the film-forming temperature and reducing the amount of film-forming aids are achieved. A pre-emulsification process and a semi-continuous seeded emulsion polymerization mode are adopted, and acrylate emulsion with a core / shell structure and excellent performance is prepared and can be used for environment-friendly wood coatings.

Description

[0001] technical field

[0002] The invention belongs to a core-shell emulsion production process, in particular to an environment-friendly core-shell emulsion production process for wood lacquer coatings.

[0003] Background technique

[0004] With the further improvement of environmental protection regulations, new low-VOC or zero-VOC emission coatings have become the focus of research and development, and the research and development of water-based wood coatings has attracted more attention. In my country, compared with the general application of architectural latex paint, the water-based ratio of wood coatings is far smaller than that of architectural paints. If water-based wood coatings can replace or partially replace solvent-based wood coatings, its environmental protection and social and economic benefits are very significant. At present, due to the shortcoming of "hot sticky and cold brittle" and containing a large amount of emulsifiers, acrylic emulsions are not ...
