Abstract
The invention relates to polypropylene with a bacteriostasis function. The polypropylene comprises the following ingredients by weight: 80 parts of polypropylene, 0.15-0.3 part of a compound antibacterial agent and 0.2-0.3 part of a plasticizer, wherein the compound antibacterial agent is prepared from the following raw materials by weight: 40 percent of an organic bacteriostatic agent, 35 percent of nano titanium dioxide and 25 percent of chitosan; the organic bacteriostatic agent comprises the following raw materials by weight percent: 35 percent of terpenic oil, 25 percent of a scutellaria baicalensis extract and 30 percent of clove oil. As the compound antibacterial agent is added into the polypropylene with the bacteriostasis function, the bacteriostatic effect of the polypropylene is improved, and staphylococcus aureus and colibacillus can be well inhibited; as the traditional Chinese medicine extract is mixed with nano titanium dioxide, chitosan and the like, the bacteriostatic and bactericidal effects are greatly improved, and the effect is greatly higher than the single using effect.
Description
Technical field
The invention belongs to plastic applications, be specifically related to a kind of polypropylene with bacteriostatic action.
Background technology
Polypropylene is the polymkeric substance of nontoxic, odorless, tasteless oyster white height crystallization, and density only has 0.90--, and " 0.91g/cm3 is one of kind the lightest in current all plastics.It is stable especially to water, and the water-intake rate in water is only 0.01%, molecular weight about 80,000 one 15 ten thousand.Good moldability, but because of shrinking percentage large (being 1% ~ 2.5%), thick article easily caves in, and to the higher part of some dimensional precisioies, is difficult to reach requirement, product surface good luster.Polypropylene is widely used, and be the important source material of food product pack, but existing polypropylene material does not have bacteriostatic action, causes polypropylene articles in use breed bacteria, affects the security in use procedure.
Summary of the invention
The object of this invention is to provide a kind of polypropylene with bacteriostatic action, promote the anti-microbial property of material.
The present invention is achieved through the following technical solutions:
There is a polypropylene for bacteriostatic action, comprise by weight: polypropylene 80 parts, complex antimicrobials 0.15-0.3 part, softening agent 0.2-0.3 part;
Described complex antimicrobials is made up of the raw material of following weight ratio by weight: organic fungistat 40%, nano titanium oxide 35%, chitosan 25%;
Described organic fungistat is made up of the raw material of following weight percent by weight: pine camphor oil 35%, Radix Scutellariae extract 25%, Syzygium aromaticum stem oil 30%.
Preferably, described softening agent is the one in dibutyl phthalate, diethyl phthalate.
Use organic fungistat, nano titanium oxide, chitosan used in combination in the present invention, enhance its fungistatic effect, and composite after can reduce the add-on of antiseptic-germicide, polyacrylic mechanical property can not be reduced.
Beneficial effect of the present invention: the polypropylene with bacteriostatic action provided by the invention passes through to add complex antimicrobials in polypropylene, improve polyacrylic fungistatic effect, for streptococcus aureus, intestinal bacteria, there is good inhibition, and use Chinese medical extract and nano titanium oxide, chitosan etc. used in combination, greatly improve effect that is antibacterial, sterilization, obviously promote than single use fungistatic effect, the fungistatic effects such as the food pack made are obvious.
