Abstract
The invention relates to antibacterial polyvinyl chloride. The antibacterial polyvinyl chloride comprises the following components in parts by weight: 80 parts of polyvinyl chloride, 0.15-0.3 part of a composite antibacterial agent and 0.2-0.3 part of a plasticizer; the composite antibacterial agent is prepared from the following raw materials in percentage by weight: 40% of an organic antibacterial agent, 35% of nano silver oxide and 25% of chitin; the organic antibacterial agent is prepared from the following raw materials in percentage by weight: 35 % of eucalyptus oil, 25% of a radix scutellariae extract and 30% of clove oil. According to the antibacterial polyvinyl chloride, the composite antibacterial agent is added into polyvinyl chloride, so that the bacteriostatic effect of the polyvinyl chloride is improved, and the polyvinyl chloride has an excellent inhibiting effect on staphylococcus aureus and colibacillus; through mixing of the Chinese herbal extracts with nano silver oxide, chitin and the like, the bacteriostatic and the bacteriocidal effect is greatly improved, and the use effect of polyvinyl chloride is obviously improved compared with a single use effect.
Description
Technical field
The invention belongs to plastic applications, be specifically related to a kind of antibacterial polyvinyl chloride.
Background technology
The PVC molecular weight that PVC industry is produced, generally in 50,000 ~ 110,000 scopes, has larger polymolecularity, the reduction of molecular weight with polymerisation temperature and increasing; Without definite melting point, 80 ~ 85 DEG C start to soften, and 130 DEG C become viscoelastic state, and 160 ~ 180 DEG C start to change viscous state into; There is good mechanical property, about tensile strength 60MPa, shock strength 5 ~ 10kJ/m2; There are excellent dielectric properties.
PVC was once the general-purpose plastics that output is maximum in the world, and application widely.All be widely used in material of construction, mechanicals, daily necessities, flooring laminate, floor tile, leatheroid, tubing, electric wire, packing film, bottle, foam material, sealing material, fiber etc.
Polyvinyl chloride is widely used, and be the important source material of food fresh keeping membrane, but existing pvc material does not have bacteriostatic action, causes polrvinyl chloride product 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 antibacterial polyvinyl chloride, promote the anti-microbial property of material.
The present invention is achieved through the following technical solutions:
A kind of antibacterial polyvinyl chloride, comprises: polyvinyl chloride 100 parts, complex antimicrobials 0.15-0.3 part, softening agent 0.2-0.3 part by weight;
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%, chitin 25%;
Described organic fungistat is made up of the raw material of following weight percent by weight: Oil of Eucalyptus 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, chitin used in combination in the present invention, enhance its fungistatic effect, and composite after can reduce the add-on of antiseptic-germicide, extend the antibacterial cycle, the mechanical property of polyvinyl chloride can not be reduced.
Beneficial effect of the present invention: antibacterial polyvinyl chloride provided by the invention by adding complex antimicrobials in polyvinyl chloride, improve the fungistatic effect of polyvinyl chloride, for streptococcus aureus, intestinal bacteria, there is good inhibition, and use Chinese medical extract and nano phase ag_2 o, chitin 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 fresh keeping membrane made are obvious.
