Problems solved by technology

At present, the antibacterial and bactericidal preparations on the market are mostly chemical components as the main components, and the antibacterial and bactericidal effects are not ideal. Moreover, bacteria and fungi are prone to develop resistance after long-term use, and increasing the dosage will pollute the environment.

Embodiment 1

[0022] A bactericidal and bacteriostatic agent is characterized in that, calculated by mass percentage, the bactericidal and bacteriostatic agent includes chitosan 0.1wt%, cationic polymer 0.2wt%, fruit acid 0.2wt%, nanometer zinc oxide 0.5wt%, 0.1wt% of nano-silver ions, 0.8wt% of biguanide salt, and the balance is solvent.

[0023] Wherein, the solvent is pure water. The cationic polymer is an aromatic polymer material grafted with a halomethyl group on the surface, and the aromatic polymer material is polysulfone. The fruit acid is grape acid; the effective substance content in the fruit acid is greater than 99%. The particle size of the nanometer zinc oxide is less than 5 nanometers. The nano-silver ions are trivalent nano-silver.

Embodiment 2

[0025] In this embodiment, the similarities with Embodiment 1 will not be repeated. The difference is that in this embodiment, a bactericidal and bacteriostatic agent is characterized in that, calculated by mass percentage, the bactericidal and bacteriostatic agent includes Chitosan 0.2wt%, cationic polymer 0.6wt%, fruit acid 1wt%, nanometer zinc oxide 2wt%, nanometer silver ion 0.5wt%, biguanide salt 2wt%, and the balance is pure water. The cationic polymer is an aromatic polymer material grafted with a halomethyl group on the surface, the aromatic polymer material is polyarylamide, and the fruit acid is citrus acid.

Embodiment 3

[0027] In this embodiment, the similarities with Embodiment 1 will not be repeated. The difference is that in this embodiment, a bactericidal and bacteriostatic agent is characterized in that, calculated by mass percentage, the bactericidal and bacteriostatic agent includes Chitosan 0.3wt%, cationic polymer 1wt%, fruit acid 2wt%, nanometer zinc oxide 4wt%, nanometer silver ion 1wt%, biguanide salt 4wt%, and the balance is pure water. The cationic polymer is an aromatic polymer material grafted with halomethyl groups on the surface, the aromatic polymer material is aromatic polyester, and the fruit acid is malic acid.

Abstract

The invention discloses a bactericidal bacteriostatic agent. The bactericidal bacteriostatic agent is characterized by comprising the following components in percentage by weight: 0.1-0.3 percent of chitosan, 0.2-1 percent of cationic polymer, 0.2-2 percent of tartaric acid, 0.5-4 percent of nano-zinc oxide, 0.1-1 percent of nano-silver ions, 0.8-4 percent of guazatine and the balance being a solvent. The bactericidal bacteriostatic agent is rich in raw material sources and low in preparation cost and has bactericidal and bacteriostatic effects and small side effect.

Description

technical field [0001] The invention belongs to the field of bactericidal and bacteriostatic technology, and relates to a bactericidal and bacteriostatic agent. Background technique [0002] Wounds can be defined as skin defects caused by mechanical, electrical, thermal, chemical and other factors. Common injuries to human skin mainly include burns, scalds, acute or chronic ulcers, surgical wounds, etc. After a large area of ​​skin is injured, it is easy to be infected by bacteria, loss of body fluids and various complications. In severe cases, it can lead to increased metabolism, decreased body temperature, excessive loss of water and protein, and disorders of the endocrine and immune systems, etc., and even endanger the skin. Life, these are all related to the loss of skin barrier function. Most of the bacteriostatic and bactericidal preparations currently on the market are chemical components as the main components, and the bacteriostatic and bactericidal effects are not...
