Antibacterial hydrophobic dendritic polyacrylate emulsion and preparation method thereof

Abstract

The invention discloses an antibacterial hydrophobic dendritic polyacrylate emulsion and a preparation method thereof. The polyacrylate emulsion comprises the following raw materials in parts by mass: 60-80 parts of methyl methacrylate, 30-50 parts of acrylic acid, 15-25 parts of a fluorine-containing acrylate monomer, 10-15 parts of vinyl silicone oil, 10-15 parts of heptanol, 15-25 parts of pentaethylenehexamine, 1.5-3 parts of a catalyst, 1-2 parts of an initiator, 20-30 parts of modified nano zirconium phosphate, 3-4 parts of allyloxy nonylphenoxy propanol polyoxyethylene ether ammonium sulfate and 120-200 parts of deionized water. According to the preparation method, heptanol and pentaethylenehexamine are used as inner cores for the first time, esterification reaction and amidation reaction are carried out on the inner cores and -COOH in an acrylic monomer, addition polymerization is carried out on the inner cores, methyl methacrylate and a fluorine-containing acrylate monomer under the action of an initiator, and a fluorine-containing polyacrylate branched chain inner shell is formed; and further graft copolymerization with vinyl silicone oil and modified nano zirconium phosphate is implemented to form the antibacterial, anti-aging and hydrophobic dendritic polyacrylate emulsion with a core-inner shell-outer shell structure.

Description

technical field [0001] The invention belongs to the field of polymer synthesis, and in particular relates to an antibacterial hydrophobic dendritic polyacrylate emulsion and a preparation method thereof. Background technique [0002] Dendrimers, also known as branched polymers, are linear polymers with dendrons on each repeating unit, similar in topology to hyperbranched polymers. Dendritic polyacrylate is a special graft polymer with polyacrylate as the main chain. It has a molecular imitation sphere structure, more active end groups are exposed, and the crosslinking density is high. It is the most promising high surface protection film. one of the materials. Dendritic polyacrylate is a dendritic polymer with polyacrylate as the main chain, which has the characteristics of good hydrodynamic properties, high solubility, and high reactivity. At present, the research and reports on dendritic polyacrylate are relatively few. Few, the research and development of functional den...
