Abstract
The invention discloses a triblock fluorosilicone acrylic ester modified polyurethane emulsion and a preparation method thereof, wherein the method utilizes double-end vinyl siloxane modified polyacrylate and fluorine-containing acrylic ester to cooperatively modify polyurethane, and adopts a segmented polymerization method to prepare aqueous polyurethane-acrylic ester emulsion with a triblock structure; the middle of the obtained product is polyurethane, one end of the polyurethane is connected with an organosilicon modified polyacrylate segment, and the other end of the polyurethane is connected with an organofluorine modified polyacrylate segment. According to the invention, the acrylic ester chain segment is introduced, and simultaneously, the organic fluorine and organic silicon groups are introduced, so that the hardness, corrosion resistance, light resistance and yellowing resistance of the aqueous polyurethane emulsion are improved, and the high temperature resistance, stain resistance, solvent resistance and water resistance of the traditional WPUA are greatly improved.
Description
Technical Field
The invention belongs to the field of water-based paint, and particularly relates to a triblock fluorine-silicon synergistic modified water-based polyurethane-acrylate emulsion and a preparation method thereof.
Background
The water-based polyurethane acrylate (WPUA) has the advantages of polyurethane and polyacrylate at the same time. Polyacrylate has the advantages of high hardness, corrosion resistance, light resistance, low production cost, yellowing resistance and the like, and excellent wear resistance, weather resistance and elasticity are excellent properties possessed by polyurethane, so that WPUA is widely used in various industries of people living and industrial production. However, WPUA introduces a certain number of hydrophilic groups or atoms or groups with strong hydrophilic ability on the molecular structure, so that the WPUA has poor hydrophobic and oleophobic ability, solvent erosion resistance and mechanical properties.

TABLE 1 test results of the three-block fluorosilicone modified waterborne polyurethane-acrylate coatings of the invention
As can be seen from the above table, the present invention utilizes a co-modified polyurethane of a double-ended vinyl siloxane modified polyacrylate and a fluoroacrylate. Under the action of an initiator, through the segmented polymerization reaction of the polyurethane prepolymer and acrylic ester, an organosilicon modified polyacrylate segment and an organofluorine modified polyacrylate segment are respectively introduced at two ends of the polyurethane. Because the organic fluorine silicon modified polyacrylate chain segment and the polyurethane chain segment have better compatibility, the problem of poor compatibility caused by directly introducing the organic fluorine silicon group is avoided, and the obtained emulsion has good storage stability and freeze thawing stability. Meanwhile, due to the introduction of organosilicon and organic fluorine groups, a large number of C-F, si-O bonds exist in a molecular chain, so that the hydrophobicity, the water resistance and the mechanical property of the coating can be effectively improved.
The embodiments of the invention are not limited to the examples described above, but all modifications and variants based on the description described above fall within the scope of protection of the appended claims, without being limited to specific details.
