Abstract
The invention discloses an antibacterial plastic used for food. The antibacterial plastic comprises, by weight: 90 parts of PE resin, 15 parts of a silver ion antibacterial agent, 7 parts of a lubricant, 3 parts of natural hydrotalcite, 10 parts of a plasticizer, and 10 parts of a composite lead salt stabilizer. The antibacterial plastic provided by the invention has an antibacterial ratio of more than 90% on Escherichia coli and Staphylococcus aureus, and has a long antibacterial time. When the antibacterial plastic provided by the invention is applied to preparation of preservative films, the preparation process is simple, the color stability, antibacterial properties, physical mechanical properties and light aging properties of the preservative films can all reach the requirements of corresponding standards.
Description
Technical field
The invention belongs to chemical material field, relate to a kind of food antibiotic plastic.
Background technology
Antibiotic plastic refers to and in plastics, adds one or several specific antiseptic-germicides, make plastics there is inherent germ resistance, be that a class has antibacterial and type material bactericidal property, thereby the bacterium of staiing at plastics and product surface thereof can be killed or suppress its breeding within the regular hour.Compare with physical disinfection method with conventional chemistry, use antibiotic plastic sterilization to there is efficient and long-lasting, not only economy but also convenient.
At present, for the antiseptic-germicide of plastics mainly: organic and inorganic, natural three large series.Because the antibiotic timeliness of inorganic antiseptic is long, and high temperature resistant, can adapt to plastic working, be widely used in antibiotic plastic.Silver zeolite is current the most frequently used plastics inorganic antiseptic, and silver zeolite complex compound has very strong anti-microbial property, and its fungistatic effect to intestinal bacteria and streptococcus aureus is better.Silver zeolite complex compound is evenly distributed in goods, and precipitation rate is mild, and anti-microbial property is good, and the time length is long.But the discoloration problem that silver ions inorganic antiseptic exists is difficult to solve always.
Summary of the invention
Technical problem to be solved by this invention is to provide the food anti-biotic material that a kind of physicals is good, colour stability is good.
For solving above technical problem, a kind of food antibiotic plastic of the present invention, the weight part of each component is as follows:
Above-mentioned silver ion antimicrobial agent be take wustite oxide complex as carrier.
Above-mentioned softening agent is dioctyl phthalate (DOP) or diphenyl phthalate.
Above-mentioned lubricant is one or more of stearic acid, oxidized polyethlene wax, calcium stearate, lead stearate and paraffin.
Further, a kind of food antibiotic plastic, the weight part of each component is as follows:
A kind of food of the present invention is with antibiotic plastic in the preparation: by each component extruding pelletization after high-speed mixing according to a conventional method.
Compared with prior art, the beneficial effect that the present invention has is:
The present invention utilizes composite oxides nanometer CuFe
2o
4as silver-colored carrier, prepare antiseptic-germicide, this antiseptic-germicide has discoloration-resistant, weathering resistance and stable on heating advantage, can be potent antibiotic, antibacterial, effect is lasting, to the antibiotic rate of intestinal bacteria and streptococcus aureus, can reach more than 90%, and the antibiotic time is permanent.Use antibiotic plastic of the present invention when preparing preservative film, preparation technology is simple, and the colour stability of preservative film, anti-microbial property, physical and mechanical properties and photooxidation aging property all reach the requirement of respective standard.
