Preparation Of Novel Antibacterial Agents And Application In Pastics

Rare Earth Lanthanum Coordination and guanidine antimicrobial polymeric antimicrobial agents compared with other antimicrobial,Rare Earth Lanthanum Coordination and guanidine antimicrobial polymeric antimicrobial agents have advantages such as remarkable of the antibacterial effect simple process,less volatile,difficult to transfer antibiotic group,more durable antimicrobial function, thermal stability high,easy to store,inexpensive and can be widely used in plastics, coatings, powder coatings, textile and other fields and many other advantages. The study consists of two parts:(1) By choosing oxide, cinnamic acid, imidazole was prepared by combining inorganic and organic way trying to prepare a heat resistance, excellent anti-bacterial and fluorescence properties of rare earth lanthanum ternary antimicrobial agent, was investigated ternary coordination of La antibacterial agents, thermal stability, antimicrobial and fluorescence properties of the antibacterial mechanism of antibacterial agents. The results show that La antimicrobial agent with good thermal stability and antibacterial properties. Investigated La Addition on the LDPE antimicrobial and antibacterial properties of the mechanical results show that when the amount of antimicrobial agent added to 2%,LDPE has the availability of excellent mechanical and antibacterial properties.(2) Used as antibacterial group guanidine, guanidine hydrochloride and maleic anhydride or acrylic acid amide reaction carried out, and then with the styrene copolymer, by changing reaction conditions and ratio of yield, defined polymeric guanidine antimicrobial agents and the ratio of optimal reaction conditions, and by infrared spectroscopy and thermal gravimetric analysis examined whether it contains anti-bacterial antimicrobial groups and thermal stability. The results show that the antibacterial agents containing guanidine, and have excellent thermal stability and antibacterial properties. Investigated guanidine polymer-based antimicrobial agent addition on PP mechanical, anti-bacterial, flame retardant properties. The results show that the addition of antimicrobial agents increases, growing antibacterial properties of polypropylene, but the mechanical properties and flame retardant properties have some effect, when the antimicrobial agent added reached 3%, will have a relatively good mechanical, antimicrobial, resistance combustion performance.
