Crosslinking fluorine modified acrylic ester nanometer polymer emulsion and preparation method thereof

Abstract

The invention relates to crosslinking fluorine modified acrylic ester nanometer polymer emulsion and a preparation method thereof. The crosslinking fluorine modified acrylic ester nanometer polymer emulsion is prepared from the following six main components through half-continuous seed emulsion polymerization, wherein in the six main components, a fluorine monomer accounts for 10-25 percent of the whole monomer mass, an acrylic ester monomer accounts for 20-30 percent of the whole monomer mass, a metacrylic ester monomer accounts for 10-25 percent of the whole monomer mass, 4) crosslinking monometer methacrylic acid hydroxyalkyl ether accounts for 5-10 percent of the whole monomer mass, 5) a dimeric surfactant accounts for 1.5-3.5 percent of the whole monomer mass, and 6) a water-soluble azo initiator accounts for 1-3 percent of the whole monomer mass. The crosslinking fluorine modified acrylic ester nanometer polymer emulsion has the advantage that a latex film is high in hydrophobicity, weather resistance, chemical resistance and high-temperature resistance after nano emulsion is subjected to film formation.

Description

technical field [0001] The invention relates to a cross-linked fluorine-modified acrylate nanometer polymer emulsion and a preparation method thereof. The polymer emulsion can be used in the fields of coatings, adhesives, finishing agents, leather finishing agents and the like. Background technique [0002] The fluorine-containing acrylate polymer emulsion not only retains the good film-forming properties and adhesion of the polyacrylate emulsion, but also has the excellent performance of the fluorine-containing polymer to a certain extent, showing hydrophobic, oleophobic and anti-fouling surface characteristics. It is widely used in the fields of high performance coating, textile finishing, leather and packaging. The fluorocarbon nanopolymer emulsion also has the following unique advantages: good permeability and wettability, strong adhesion to the substrate; small particle size, can form a dense coating film, and the formed coating film has high gloss; The particle size ...
