Abstract

The invention discloses an anti-aging self-flame-retardant hyperbranched fluorine-containing polyacrylate emulsion and a preparation method thereof. The anti-aging self-flame-retardant hyperbranched fluorine-containing polyacrylate emulsion comprises the following raw materials in parts by mass: 50-60 parts of methyl acrylate, 20-30 parts of methacrylic acid, 15-20 parts of perfluorooctyl ethyl acrylate, 25-35 parts of pentaerythritol tetramine, 15-20 parts of itaconic acid, 10-15 parts of dicyandiamide, 3-5 parts of guanidine phosphate, 4-8 parts of amino trimethylene phosphonic acid, 1-2 parts of a catalyst, 0.5-1.5 parts of an initiator, 20-30 parts of functionalized layered double hydroxides, 2-3 parts of allyloxy nonylphenoxy propyl alcohol polyoxyethylene ether ammonium sulfate, 25 to 30 parts of N, N-dimethyl formamide and 80 to 120 parts of deionized water. The fluorine-containing hyperbranched fluorine-containing polyacrylate emulsion prepared by the method disclosed by the invention has excellent self-flame-retardant, antibacterial and anti-aging characteristics, high molecular weight, excellent solubility, hydrophobic and oleophobic properties and high film-forming stability.

Description

technical field [0001] The invention belongs to the technical field of hyperbranched polymer synthesis, and in particular relates to an anti-aging self-flame-retardant hyperbranched fluorine-containing polyacrylate emulsion and a preparation method thereof. Background technique [0002] Hyperbranched polymers are special polymers with a highly branched topology, with a large number of branch nodes and active end groups. Compared with linear polyacrylates, hyperbranched multi-arm polyacrylates have a unique spherical three-dimensional compact structure, small hydrodynamic radius of gyration, less molecular chain entanglement, more active end groups, easy to dissolve, and low viscosity. It does not change with the increase of molecular weight, showing excellent flow properties, high stability and film-forming properties. At present, there are few studies and reports on hyperbranched polyacrylates, and the development of functional hyperbranched polyacrylates or the functional...
