Abstract
The invention relates to an antibacterial polyethylene film which comprises the following components in parts by weight: 80-100 parts of polyethylene master batch, 0.05-0.09 part of thyme essential oil, 0.6-1 part of citric acid, 3-4 parts of xylitol, 1-5 parts of maleic anhydride, 1-2 parts of nano silicon dioxide or nano calcium carbonate, 0.05-1 part of antioxidant, 2-3 parts of coupling agent and 0.4-0.8 part of dicumyl peroxide. Compared with the prior art, the film can inhibit bacteria around the film from generation. Compared with the common commercially-available PVC (polyvinyl chloride) film, the antibacterial polyethylene film has obvious inhibitory effects on Staphylococcus aureus, Escherichia coli and other bacteria. The antibacterial agent used by the antibacterial polyethylene film is a pure natural plant-extracted antibacterial agent, can be used for a long time, and is safe and nontoxic.
Description
Technical field
The present invention relates to film applications, be specifically related to a kind of polyethylene film, relate to the polyethylene film with bacteriostasis property more specifically.
Background technology
Polyethylene (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.
Traditional PVC film shortcoming bacteria resistance function, though have the research to the PVC film with bacteria resistance function at present, but still Shortcomings.Chinese patent CN103102618A, a kind of TiO2 Ag/PVC compound bacteriostatic film, though this patent adds modification TiO2 Ag in the film, makes film have good bacteriostasis property, but still containing harmful softening agent; Chinese patent CN102101928A, a kind of antimicrobial preservative film, though this patent with the addition of silver ion antimicrobial agent in preservative film, to make it have antibacterial, but wherein still containing phthalic ester plasticizer, and there are some researches show, though silver ion antimicrobial agent has stronger bacteria resistance function, if still harm can be produced to HUMAN HEALTH after accidentally taking in human body.
Thymus vulgaris, the main place of production is France in southern Europe, Spain, Mediterranean Sea state and Egypt, China, belong to evergreen shrubs herbaceous plant, highly not high, leaf is green, flower is pink, thyme oil is then from its flower of distillation and leaf, also somewhat green in moderate yellowish brown, because fragrance has strong herbal medicine and pine tar taste, after being stained with blade of grass juice, taste can be far with oneself, so southern china claims Murraya paniculata (L.) Jack or Leaf and twig of Common Jasminorange.Thyme oil has good fungistatic effect, and the mould common to general environment and bacterium have obvious restraining effect.Current thyme 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 technical barrier urgently to be resolved hurrily.
Summary of the invention
The object of the invention is to solve the problem of PVC film shortcoming bacteria resistance function in prior art, be to provide a kind of antibacterial polyethylene film, described polyethylene film has bacteria resistance function, environment-protecting asepsis, is widely used in the fields such as building materials furniture film, toy and food product pack.
Concrete technical scheme of the present invention is as follows:
A kind of antibacterial polyethylene film, comprises following raw material according to weight parts:
Preferably comprise following raw material according to weight parts:
Described antioxidant is β-positive octadecanol ester of (3,5-di-tert-butyl-hydroxy phenyl) propionic acid or four [β-(3,5-di-tert-butyl-hydroxy phenyl) propionic acid] pentaerythritol ester.
Described coupling agent is selected from the one in vinyl three ('beta '-methoxy oxyethyl group), vinyltriethoxysilane, aluminic acid vinegar coupling agent.
Thyme oil oil has fragrant and sweet and strong medicinal herbs taste, taste can spread far, the present invention adopts environmental protection pure natural plant fungistat thyme oil, adopt citric acid, Xylitol and maleic anhydride composite, utilize the synergy of itself and thyme oil, effectively suppress growing of film surrounding bacterial.
Compared with prior art, film of the present invention can suppress the bacteria breed around film, compared with common commercially available PVC film, all has remarkable inhibition to the bacterium such as streptococcus aureus, intestinal bacteria.The fungistat that the present invention uses extracts fungistat for natural plant, can life-time service, safety non-toxic.
