Problems solved by technology

[0003] Existing acrylic emulsions contain a small amount of small molecule emulsifiers, which are used as film-forming substances for water-based plastic paints, which will lead to a decrease in the performance of the paint film
The small molecule emulsifier plays a role in stabilizing the emulsion particles in the emulsion synthesis, but after the emulsion is formed into a film, the small fen will float on the surface of the paint film, resulting in a decrease in the alcohol resistance of the paint film

Abstract

The invention belongs to the technical field of water-based paint. A water-based alcohol-resistant self-crosslinking nano emulsion is prepared from the following components in percentage by mass: 10 to 20 percent of alkali-soluble macromolecular stabilizer, 0.1 to 0.5 percent of sodium persulfate, 0.3 to 0.9 percent of vinyl unsaturated carboxylic acid, 1 to 10 percent of methacrylate, 8 to 15 percent of styrene, 0.1 to 2.5 percent of crosslinking monomer, 1 to 5 percent of ammonia water, 0.5 to 2.5 percent of nano silicon dioxide liquid and the balance of water, wherein the alkali-soluble macromolecular stabilizer is alkali-soluble solid resin. The emulsion adopts the alkali-soluble macromolecular stabilizer as an emulsifier of the emulsion, so that the alcohol resistance of a paint film is effectively improved, and the problem of gloss loss caused by dissolution of the paint film by ethanol is avoided.

Description

technical field [0001] The invention belongs to the technical field of water-based coatings, and in particular relates to a water-based alcohol-resistant self-crosslinking nanoemulsion and a preparation method and application thereof. Background technique [0002] Acrylic emulsion has become the largest resin coating because of its low price, good gloss and color retention, heat aging resistance and ultraviolet aging resistance. Acrylate copolymer is an amorphous polymer, which has the problems of poor gloss, hardness, fullness, abrasion resistance, chemical resistance and scratch resistance of the coating film. How to improve the film hardness and chemical resistance of water-based plastic paints with acrylate copolymer emulsions as film-forming substances is a difficult problem in the research and development and synthesis of acrylate copolymer emulsions. [0003] Existing acrylic emulsions contain a small amount of small molecule emulsifiers, which are used as film-formi...
