Embodiment A1

[0034] (1) Add 30 parts of water into the reaction kettle, then add 20 parts of neopentyl glycol, heat to 40°C, add 0.6 parts of hexamethylene tetraamine to adjust the pH to 8.5±0.1, and obtain buffered neopentyl glycol Joint agent solution;

[0035] (2) Keep the reactor at 40°C, add 2 parts of active nano-zinc oxide and 30 parts of nano-rutile titanium dioxide to the buffered neopentyl glycol solution, control the temperature of the material at 45°C, stir for 25min, and cool to At room temperature, a composite antibacterial agent is obtained through infiltration and coupling, that is, neopentyl glycol / zinc oxide / titanium dioxide nanocomposite antibacterial agent.

Embodiment A2

[0037] (1) Add 35 parts of water into the reaction kettle, then add 25 parts of neopentyl glycol, heat to 40°C, add 0.7 parts of hexamethylene tetraamine to adjust the pH to 8.5±0.1, and obtain buffered neopentyl glycol Joint agent solution;

[0038] (2) Keep the reactor at 40°C, add 10 parts of active nano-zinc oxide and 30 parts of nano-rutile titanium dioxide to the buffered neopentyl glycol solution, control the temperature of the material at 45°C, stir for 25min, and cool to At room temperature, a composite antibacterial agent is obtained through infiltration and coupling, that is, neopentyl glycol / zinc oxide / titanium dioxide nanocomposite antibacterial agent.

Embodiment A3

[0040] (1) Add 30 parts of water into the reaction kettle, then add 25 parts of neopentyl glycol, heat to 40°C, add 0.5 parts of hexamethylenetetramine to adjust the pH to 8.5±0.1, and obtain buffered neopentyl glycol Joint agent solution;

[0041] (2) Keep the reactor at 40°C, add 10 parts of zinc sulfate and 30 parts of nano-rutile titanium dioxide to the buffered neopentyl glycol solution, control the temperature of the material at 45°C, stir for 25min, and cool to room temperature through the jacketed water of the reactor. The composite antibacterial agent is obtained through infiltration and coupling, that is, neopentyl glycol / zinc sulfate / titanium dioxide nanocomposite antibacterial agent.

Abstract

The invention relates to a board-spectrum efficient antibacterial amino molding material. An alcohol / zinc / titanium nano-composite antibacterial agent of the board-spectrum efficient antibacterial amino molding material is composed of the following components in parts by weight: 20-30 parts of alcohol compound, 0-25 parts, excluding 0 part, of nano zinc compound, 0-35 parts, excluding 0 part, of nano titanium dioxide, 0.1-5 parts of hexamethylenetetramine and 40-50 parts of water. The antibacterial amino molding material is composed of the following components in parts by weight: 2000-4000 parts of urea, 4000-8000 parts of formaldehyde, 300-400 parts of melamine, 10-150 parts of nano-composite antibacterial agent, 50-150 parts of hexamethylenetetramine, 20-50 parts or 50-100 parts of ammonium sulfamate curing agent, 100-500 parts of filler, 1000-2500 parts of cellulose, 20-40 parts of lubricant and 1-100 parts of dispersant. The antibacterial ratio of a molded product of the amino molding material to escherichia coli, staphylococcus aureus, Klebsiella pneumonia, salmonella typhimurium and enterococcus faecalis is greater than 99.9%, and the value of the antibacterial activity of the molded product is greater than 4, and the molded product of the amino molding material is good in mechanical properties and moldability.

Description

technical field [0001] The invention relates to a broad-spectrum high-efficiency antibacterial amino molding compound. The broad-spectrum mainly refers to the antibacterial effects of amino molding compound molding products against the growth of Escherichia coli, Staphylococcus aureus, Klebsiella pneumoniae, Salmonella typhimurium, Enterococcus faecalis, etc.; Refers to the antibacterial rate of amino molding plastic molding products greater than 99.9%, and the antibacterial activity value is greater than 4; the amino molding plastic is a thermosetting compound composed of urea, formaldehyde, melamine, nanocomposite antibacterial agents and additives, mainly used as a high-grade hygiene Molding materials for sanitary ware, tableware, electrical switches, electrical casings, sockets, circuit breakers and lighting appliances. technical background [0002] Amino molding compound raw materials are cheap, free to color, high surface hardness, smooth, with excellent heat resistan...
