Abstract

The invention provides organosilicone-acrylate nanometer emulsion. The organosilicone-acrylate nanometer emulsion is prepared through the following steps that 1, nanometer zinc hydroxide is prepared; 2, organizing treatment is performed on the nanometer zinc hydroxide; 3, a mixed monomer is prepared and mixed with the organized zinc hydroxide to form a monomer mixture, and an initiator solution and an emulsifier solution are prepared; 4, the monomer mixture and an organosilicone monomer are processed through emulsion polymerization through the initiator and the emulsifier. The organosilicone-acrylate nanometer emulsion has the super hydrophobicity and the very good acid and alkali resistance.

Description

Technical field: [0001] The invention relates to a nanoemulsion, in particular to an organosilicon-acrylate nanoemulsion and a preparation method thereof. Background technique: [0002] Nanoemulsion is an isotropic, thermodynamically stable, transparent or translucent colloidal dispersion system composed of oil, water, emulsifier and co-emulsifier. Since Hoar et al. used oil, water, emulsifiers and alcohols to obtain a transparent and uniform microemulsion system in 1943, due to the particularity of the emulsion polymerization mechanism, the diversity of polymerization methods and the wide range of applications, nanoemulsions have become the most popular in the world today. One of the hot research areas. [0003] Acrylate emulsions have excellent weather resistance, film-forming properties and cohesiveness, and are widely used in coatings and adhesives, but at the same time, they have disadvantages such as poor water resistance, moisture permeability and stain resistance; o...
