Problems solved by technology

[0002] Generally, antibacterial agents are divided into organic antibacterial agents and inorganic antibacterial agents. Organic antibacterial agents generally have disadvantages such as poor heat resistance, volatile, difficult to store for a long time, easy to decompose to produce harmful substances, and poor safety. Inorganic antibacterial agents are usually powder solid, difficult to disperse in water, poor solubility
In addition, the antibacterial agents on the market only have an antibacterial effect on certain bacterial species, and cannot reach the universality of antibacterial

Embodiment Construction

[0013] A preparation process of a nano antibacterial agent, the preparation raw materials are composed of nano titanium dioxide, nano silver, nano zinc oxide and water, and its mass percentage content is: nano titanium dioxide 1-25%, preferably 10-25%; nano silver 1-10% , preferably 3-8%; the composition of nano-zinc oxide is 1-50%, preferably 20-40%; the balance is water. The nano-titanium dioxide particle diameter is 10-30 nanometers, the nano-silver particle diameter is 20-60 nanometers, and the nano-zinc oxide particle diameter is 20-40 nanometers.

[0014] Put nano-titanium dioxide and water into the reaction kettle to heat up, stir to 150°C, add nano-zinc oxide and nano-silver to react for 3 hours, cool to 30°C to obtain the finished nano-antibacterial agent. .

[0015] The Institute of Poultry Diseases of the College of Veterinary Medicine of South China Agricultural University tested the avian influenza virus. The nano-antibacterial agent diluted 1:5000 times and the ...

Abstract

The invention relates to a nano antibacterial agent and process for preparation, wherein the raw materials include (by weight percent) nano titanium oxide 1-25%, nano silver 1-10%, nano zinc oxide 1-50% and balancing water. The preparing process consists of charging nano titanium dioxide into autoclave, elevating temperature and stirring to 150 deg C, charging zinc oxide and nano silver for reacting 3 hrs, finally cooling down to 30 deg. C.

Description

technical field [0001] The invention relates to a preparation process of an antibacterial agent, in particular to a preparation process of a nanometer antibacterial agent. Background technique [0002] Generally, antibacterial agents are divided into organic antibacterial agents and inorganic antibacterial agents. Organic antibacterial agents generally have disadvantages such as poor heat resistance, volatile, difficult to store for a long time, easy to decompose to produce harmful substances, and poor safety. Inorganic antibacterial agents are usually powder solid, difficult to disperse in water, poor solubility. In addition, the antibacterial agents on the market only have an antibacterial effect on certain strains of bacteria, and cannot reach the universality of antibacterial. Contents of the invention [0003] In order to overcome the shortcomings of the above-mentioned organic antibacterial agent and inorganic antibacterial agent, the invention provides a preparatio...
