Abstract

The invention discloses a fluorocarbon elastic emulsion, and belongs to the technical field of emulsions. The fluorocarbon elastic emulsion is prepared from the following components in mass percent: 35-55% of water, 1-3% of an emulsifying agent, 5-30% of a fluorine-containing monomer, 20-30% of butyl acrylate, 5-10% of methyl methacrylate, 1-3% of acrylic acid or methylacrylic acid, 0-5% of benzophenone, 0-5% of vinylalkoxy phosphate, 0-5% of ethylene glycol dimethacrylate, and 0-3% of persulfate. The invention further provides a preparation method of the fluorocarbon emulsion. Compared with a common elastic emulsion, the elastic emulsion disclosed by the invention not only has the advantages of being high in weather resistance, chemical corrosion resistance, water resistance, stain resistance and artificial ageing resistance, but also can improve the wetting and dispersing ability on pigments and fillers, and the adhesive force and water resistance of a paint film are further improved.

Description

technical field [0001] The invention belongs to the technical field of emulsions, and relates to a fluorocarbon emulsion, in particular to a fluorocarbon emulsion and a preparation method thereof. Compared with ordinary elastic emulsion, the elastic emulsion of the present invention not only has the advantages of high weather resistance, chemical corrosion resistance, water resistance, stain resistance, artificial aging resistance, etc., but also can improve the wetting and dispersing ability of pigments and fillers , to further improve the adhesion and water resistance of the paint film. Background technique [0002] Elastic architectural coatings not only have the decorative and protective functions of ordinary exterior wall coatings, but also can maintain a certain degree of resilience in a large temperature range, so that they can adapt to the cracks on the surface of buildings and keep the coating intact. Therefore, elastic coatings It occupies an increasingly importan...
