Abstract
The invention relates to polystyrene with a bacteriostasis function. The polystyrene comprises the following ingredients by weight: 80 parts of polystyrene, 0.1-0.25 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 silver oxide and 25 percent of chitosan; the organic bacteriostatic agent comprises the following raw materials by weight percent: 35 percent of neem oil, 25 percent of a scutellaria baicalensis extract and 30 percent of clove oil. As the compound antibacterial agent is added into the polystyrene with the bacteriostasis function, the bacteriostatic effect of the polystyrene is improved, and staphylococcus aureus and colibacillus can be well inhibited; as the traditional Chinese medicine extract is mixed with nano silver oxide, chitosan and the like, the bacteriostatic and bacteriocidal 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 polystyrene with bacteriostatic action.
Background technology
Polystyrene (PS) comprises ordinary polystyrene, polystyrene foamed (EPS), high-impact polystyrene (HIPS) and syndiotactic polystyrene (SPS).Ordinary polystyrene resin is nontoxic, odorless, colourless transparent grain, like glassy hard brittle material, its goods have high transparency, and transmittance can reach more than 90%, and electrical insulation capability is good, easy coloring, processing fluidity is good, good rigidly and chemical resistance good etc.The being property of weak point of ordinary polystyrene is crisp, and shock strength is low, easily occurs stress cracking, poor heat resistance and not resistance to boiling water etc.
Polystyrene is widely used, but existing polystyrene material does not have bacteriostatic action, causes modified styrene polymer 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 polystyrene with bacteriostatic action, promote the anti-microbial property of material, promote security.
The present invention is achieved through the following technical solutions:
There is a polystyrene for bacteriostatic action, comprise by weight: polystyrene 80 parts, complex antimicrobials 0.1-0.25 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 phase ag_2 o 35%, chitosan 25%;
Described organic fungistat is made up of the raw material of following weight percent by weight: neem 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 phase ag_2 o, chitosan used in combination in the present invention, enhance its fungistatic effect, and composite after can reduce the add-on of antiseptic-germicide, the mechanical property of polystyrene can not be reduced.
Beneficial effect of the present invention: the polystyrene with bacteriostatic action provided by the invention passes through to add complex antimicrobials in polystyrene, improve the fungistatic effect of polystyrene, for streptococcus aureus, intestinal bacteria, there is good inhibition, and use Chinese medical extract and nano phase ag_2 o, chitosan etc. used in combination, greatly improve effect that is antibacterial, sterilization, obviously promote than single result of use.
