Description
Technical Field
The invention belongs to the technical field of high polymer materials, and particularly relates to a high polymer material additive with an antibacterial function and a preparation method thereof.
Background
High molecular materials are ubiquitous in our lives, and bacteria also seriously threaten the safety of lives and properties of human beings, and about 1700 people die of bacterial infection every year. In response to the situation that bacteria have become more and more intense, it has been found in the research process that antibacterial agents having a remarkable preventive and antibacterial effect on bacteria can be added to polymer materials, but the antibacterial activity of some of these antibacterial agents is problematic.
Therefore, the antibacterial material has important significance for the healthy life of human beings, and the antibacterial additive is used as an antibacterial effective component in the antibacterial material, and the selection of the antibacterial additive becomes a key factor for manufacturing the antibacterial material. The key points of the selection of the antibacterial additive are as follows: 1. the antibacterial agent has broad-spectrum antibacterial property, and various germs which damage human health, such as pseudomonas aeruginosa, staphylococcus aureus, escherichia coli, klebsiella, enterococcus, certain fungi and the like, so that the antibacterial agent with a single antibacterial variety often cannot meet the requirement of antibacterial performance. 2. The antibacterial high efficiency has two meanings, firstly, the dosage is small, and the aim of antibacterial sterilization can be achieved only by using a small dosage, so that the cost is reduced, and the antibacterial material can be used in a large range; secondly, the traditional Chinese medicine composition takes effect quickly, namely a large amount of germs can be killed in a short time, and the probability of contact between a human body and the germs is reduced. 3. The antibacterial material has strong antibacterial durability, the service life of the antibacterial material on certain durable goods is long, and the replacement frequency is low, so the antibacterial material is required to have strong antibacterial durability and can keep the capability of killing germs for a long time. 4. Low toxicity, some antibacterial materials are in direct contact with exposed human tissues, and antibacterial components of the antibacterial materials enter the human body more or less along with body fluid and blood, so that the low toxicity, particularly low acute toxicity and long-term cumulative toxicity, of the antibacterial materials to the human body must be ensured. 5. The discovery and the use of antibiotics make great contribution to the health of human beings without drug resistance, but also bring great problems in the long use process, namely drug resistance, and nowadays, super germs capable of resisting various antibiotics emerge endlessly. Therefore, ensuring the non-resistance of the antimicrobial additive also becomes a key factor in the selection of the antimicrobial agent.
However, the selection of the existing antibacterial additives has more or less problems, so that the antioxidant performance of the antibacterial additives is insufficient, and the service life of the antibacterial agents is influenced.
Disclosure of Invention

Therefore, the invention provides the high polymer material additive with the antibacterial function and the preparation method thereof, the additive is fixed on a high polymer substrate for preparing the antibacterial agent material in a chemical bond mode, has strong reducibility, can play a role in antioxidation, improves the inoxidizability of the high polymer material, and prolongs the service life.
