Abstract

The invention discloses an antibacterial anti-aging flame-retardant dendritic polyacrylate emulsion and a preparation method thereof. The antibacterial anti-aging flame-retardant dendritic polyacrylate emulsion comprises the following raw materials in parts by mass: 50 to 70 parts of methyl acrylate, 20 to 30 parts of acrylic acid, 10 to 15 parts of itaconic acid, 10 to 15 parts of melamine, 3 to 7 parts of amino trimethylene phosphonic acid, 5 to 15 parts of glucose, 10 to 20 parts of tetraethylenepentamine, 1 to 2 parts of a catalyst, 0.5 to 1.5 parts of an initiator, 15 to 25 parts of modified nano zirconium phosphate, 2 to 3 parts of allyloxy nonylphenoxy propanol polyoxyethylene ether ammonium sulfate, 30 to 40 parts of N, N-dimethylformamide and 80 to 120 parts of deionized water. The preparation method comprises the following steps: carrying out amidation reaction on-NH2 in melamine and amino trimethylene phosphonic acid and-COOH in acrylic acid and itaconic acid, carrying out esterification reaction and amidation reaction on glucose and tetraethylenepentamine serving as an inner core and free-COOH of a system, or carrying out reaction on glucose and tetraethylenepentamine and-H2PO3, and carrying out copolymerization on the obtained product and methyl acrylate under the action of an initiator so as to obtain a polyacrylate branched chain inner shell, and crosslinking thepolyacrylate branched chain inner shellwith the modified nano zirconium phosphate to realize molecular modification.

Description

technical field [0001] The invention belongs to the field of polymer synthesis, and in particular relates to an antibacterial, antiaging and flame retardant 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 developmen...
