Is antibacterial masterbatch harmful to people? Antibacterial masterbatch is to make antibacterial agents in antibacterial materials to play a good antibacterial, antibacterial long-term performance, in the use of the performance is relatively stable, but some people will think that antibacterial masterbatch may be harmful to people, in fact, there is no harm, antibacterial is to play an anti-bacterial effect, not harmful to people. One of the most harmful aspects of antibacterial agents to human body is drug resistance. So is antibacterial masterbatch harmful to people?

Common antibacterial agents can be divided into four kinds: organic antibacterial agents, inorganic antibacterial agents, polymer antibacterial agents and natural antibacterial agents. The most commonly used antibacterial agent is inorganic antibacterial agent, which is the most used antibacterial agent in China.

Effective antibacterial agents: they are similar in structure to antistatic agents, such as organic iodides, organic chlorides and their complexes, and metal salts of amino acids.

Inorganic antibacterial agent: using antibacterial metal loaded on a certain carrier, through ion exchange, adsorption, alloying or combination.

Polymer antibacterial agent: it is obtained by introducing antibacterial functional groups. According to different functional groups, it can be divided into quaternary ammonium salt type, quaternary phosphine salt type, guanidine salt type, pyridine type and organic metal copolymer.

Natural antibacterial agent: refined from plants, and now the key development is ultra-fine chitosan powder, chitin, etc.

At present, many polymer materials use inorganic antibacterial agents, such as nano silver and nano copper. If nano silver antibacterial agent is used, it will not be harmful to human body in a short time, but whether it is harmful to human body in a long time has always been a controversial topic. However, many foreign countries have data testing that nano silver can penetrate into cells and accumulate, A lot of accumulation will certainly be harmful to human body.

The above is the description of whether the antibacterial masterbatch is harmful to people, but it is generally harmless to human body, as long as it does not let the nano silver antibacterial agent accumulate for a long time, it does not matter much. Nano zinc oxide and other nano materials have made some breakthroughs in antibacterial material technology, but it still needs great efforts to open the application market of the whole plastic industry.
