Abstract
The invention relates to a polyethylene film with an antibacterial effect. The polyethylene film is composed of the following raw materials in parts by weight: 80 to 100 parts of polyethylene master batch, 0.1 to 0.3 part of clove oil, 0.6 to 1 part of critic acid, 3 to 4 parts of xylitol, 1 to 5 parts of maleic anhydride, 1 to 2 parts of nano silicon dioxide or nano calcium carbonate, 0.05 to 1 part of antioxidant, 2 to 3 parts of coupling agent, and 0.4 to 0.8 part of dicumyl peroxide. Compared to the prior art, the provided film can inhibit the bacterium propagation around the film, and has a more prominent inhibiting effect on staphylococcus aureus, colibacillus, and the like, compared with that of common PVC films in the market. The used antibacterial agent is made of pure natural plants, thus can be used for a long term, 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.
Cloves originates in Indonesia, and the area producing cloves at present mainly contains Indonesia, Zanzibar and Madagascar, and India, Pakistan and Sri Lanka also produce cloves.Hainan of China, Guangdong, Guangxi, south of Yunnan also have a small amount of plantation.Syzygium aromaticum stem oil has good fungistatic effect, and the mould common to general environment and bacterium have obvious restraining effect.Current Syzygium aromaticum stem 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 polyethylene film with bacteriostatic action, 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:
There is a polyethylene film for bacteriostatic action, comprise 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.
Syzygium aromaticum stem oil, for the dry flower of plant clove of myrtaceae is through distilling the volatile oil of gained, is yellowish or colourless clear and bright oily matter, has the special aroma of cloves.Syzygium aromaticum stem oil has broad-spectrum antibacterial effect to streptococcus aureus, intestinal bacteria, yeast, aspergillus niger etc.The present invention adopts environmental protection pure natural plant fungistat Syzygium aromaticum stem oil, adopts citric acid, Xylitol and maleic anhydride composite, utilizes its synergy with Syzygium aromaticum stem oil, effectively the growing of suppression 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.
Embodiment
