Abstract
An environmentally friendly PVC film comprises, by mass, 90-110 parts of PVC resin powder, 0.1-0.2 parts of lavender essential oil, 20-25 parts of synthetic plant ester, 4-8 parts of a heat stabilizer, and 0.2-0.6 parts of a lubricant, the heat stabilizer is one or more of calcium ricinoleate, calcium stearate, zinc stearate and magnesium stearate, and the lubricant is one or more of stearin, amine, paraffin and polyethylene wax. The environmentally friendly PVC film can inhibit growth of bacteria surrounding the film; compared with common commercial PVC films, the environmentally friendly PVC film has a substantial inhibition effect on Trichoderma viride, Escherichia coli and Staphylococcus aureus; the lavender essential oil is a natural plant extraction bacterial depressant, can be used for a long term, and is safe and nontoxic; and the synthetic plant ester and tributyl citrate are used as a plasticizer, so the health problem induced by use of phthalate-containing plasticizer products can be effectively avoided.
Description
Technical field
The invention belongs to polymeric material field, be specifically related to a kind of environment-friendly PVC film.
Background technology
PVC film is widely used in the top layer of floor, top ceiling and leather, the superiors of this surface film are paint, the main component in middle layer is polyvinyl chloride, orlop is back of the body coating adhesive, compared with common veneer film, it can merge tightly with other sheet material, within 10 years, even within 15 years, does not come unglued, therefore be loved by the people, become a kind of synthetic materials be widely used.
Softening agent conventional during current industrial production PVC film is mainly phthalate, though this kind of softening agent is functional, but because it has carcinogenic potentially dangerous, its use is very limited, China also formulates relevant laws and regulations and progressively will eliminate its application in packaging material for food, medical appliance toy, along with improving constantly of people's quality of life, the application of phthalic ester plasticizer in building material material also will be very limited, and not containing having wide practical use to the PVC film of the softening agent of human health.
Traditional PVC film shortcoming bacteria resistance function, though have the research to the PVC film with bacteria resistance function at present, but still Shortcomings.
Lavandula angustifolia is perennial herb, and the Main Cultivation area of China lavandula angustifolia is in Xinjiang, and all there is big area lavandula angustifolia planting base on many ground such as Beijing, Shenyang of present China.Herba Lysimachiae foenumgraeci quintessence oil has good fungistatic effect, and the mould common to general environment and bacterium have obvious restraining effect.Current Herba Lysimachiae foenumgraeci quintessence oil is widely used in medicine and household chemicals field, but its applied research in PVC film is very few.
In sum, the deficiency how overcoming prior art existence has become existing PVC film field skill urgently to be resolved hurrily
An art difficult problem.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art and a kind of environment-friendly PVC film is provided, tool of the present invention
There is bacteria resistance function, environment-protecting asepsis, be widely used in the fields such as building materials furniture film, toy and food product pack.
Technical scheme of the present invention is as follows:
Environment-friendly PVC film, comprises the following raw material according to mass fraction meter: PVC resin powder 90-110 part, Herba Lysimachiae foenumgraeci quintessence oil 0.1-0.2 part, synthesis vegetable esters 30-35 part, thermo-stabilizer 4-8 part, lubricant 0.2-0.6 part.
Thermo-stabilizer described above is metal soap stablizer.
Lubricant described above is fatty acid acyl amine or hydrocarbon lubricants.
The preparation method of described Herba Lysimachiae foenumgraeci quintessence oil is: take 20g lavender flower, 60 mesh sieves are crossed after pulverizing, be placed in 250mL beaker, add 150-200mL normal hexane, soak 30-50min, place in ultrasonic instrument, ultrasonic 60-80min at 40-50 DEG C, be cooled to room temperature, underpressure distillation, concentrated solution is Herba Lysimachiae foenumgraeci quintessence oil.
Preparation method of the present invention: according to mass fraction polyvinyl chloride resin, Herba Lysimachiae foenumgraeci quintessence oil, synthesis vegetable esters, tributyl citrate, epoxy soybean oil, thermo-stabilizer and lubricant added in homogenizer and be warming up to 80-90 DEG C and be uniformly mixed, deliver to forcing machine, extruder temperature controls at 120-150 DEG C, after material is delivered to plastics processing mill, material loading is to rolling press again, calender temperature is 160-180 DEG C, through calendering, embossing sizing, cooling, curling, the finished product of cutting, packing.
Principle of the present invention: the Herba Lysimachiae foenumgraeci quintessence oil of pure plant extract has light lavender, to mucormycosis, trichoderma viride, streptococcus aureus and intestinal bacteria, all there is good restraining effect, especially better to the effect of mucormycosis and trichoderma viride, under the acting in conjunction of other auxiliary agents, obtained packaging film has excellent antibacterial preservative effect, by synthesis vegetable esters with tributyl citrate is composite is used as softening agent, namely some needs to have the food of specific fragrance to use its finished product packing in use, and long-term storage also can relievedly be used safely.
Beneficial effect of the present invention:
1, film of the present invention can suppress the bacteria breed around film, compared with common commercially available PVC film, all having remarkable inhibition to trichoderma viride, intestinal bacteria and streptococcus aureus, is 72% to colibacillary bacteriostasis rate, streptococcus aureus 67%, trichoderma viride 99%;
2, the fungistat that the present invention uses extracts fungistat for natural plant, can life-time service, safety non-toxic.3rd, the present invention uses synthesis vegetable esters and tributyl citrate as softening agent, can effectively avoid because using the health problem caused containing phthalic ester plasticizer product.
