Description
Technical field
The present invention relates to a kind of polyolefin film, relate to a kind of paper compound polyolefin film that can discharge anion specifically.
Background technology
Polypropylene and polyethylene film all can be with flat embrane method productions, in flat embrane method, be divided into again coextrusion progressively biaxial tension and synchronous bidirectional stretch two kinds, wherein based on progressively biaxial tension and carry out twice stretching (promptly earlier vertically afterwards cross directional stretch) of coextrusion.
Now, carrying out compound to the polyolefin film material has been a kind of known technology, for example film and film or film and the paper mode by hot pressing is combined with each other.
Film early is compound to be that mode by means of gluing realizes, for example, applies the adhesive that one deck contains benzene in the one side of thin-film material, makes it and other film or paper are realized heat seal.Adopt the shortcoming that coating technique brought in traditional paper complex technique for overcoming, eliminate the environmental pollution that the hazardous solvent volatilization causes, and overcome the low shortcoming of film initial adhesion power that traditional solvent-free combination process brings, Chinese patent ZL 200710006100.5 discloses a kind of paper supply and has moulded bidirectional stretching polypropylene film of compound usefulness and preparation method thereof, this patent has adopted the technology of biaxial tension, and side being provided with of laminated film can with the thermal synthesis layer of paper and ink lay heat seal.This Biaxially oriented polypropylene composite membrane can be directly and paper wood or preprint paper wood to carry out hot pressing compound.
Chinese patent ZL 98811126.8 relates to a kind of multi-layered high-density polyethylene film of height biaxial orientation, wherein discloses a kind of Biaxially-oriented polyethylene film.The shortcoming of this film is can not be directly and paper wood or preprint paper wood to carry out hot pressing compound.
A kind of antibiotic fresh-keeping plastic film additive is disclosed among the Chinese patent ZL 03115757.2, this patent relates to polyethylene film, this film is owing to added additive such as tourmaline micro mist, can constantly inspire hydroxyl anion and active oxygen, thereby have antibiotic, fresh-keeping function, can be used in the packaging for foodstuff.
Summary of the invention
The present invention serves as to use object with the paper joint product, according to the handling characteristics of this paper joint product traditional polyolefin films has been done further improvement.
The paper joint product, for example the student with advertisement booklet front cover, information kit, handbag surface and aircraft food series box surface etc., through being usually used in indoor or airtight relatively environment, and belongs to the article that contact with staff with book cover, meeting and exhibition.Existing biaxial tension paper laminated film though can realize good heat seal with paper and printing ink, has the environment-friendly advantage that does not contain residual solvent or poisonous fugitive constituent, the function that does not purify air.
At existing problem in the prior art, the invention provides the polyolefin film material of the compound usefulness of a kind of paper.Owing in this polyolefin film material, added an amount of anion releasing agent, thereby made this film have the function that discharges hydroxyl anion and active oxygen.
Polyolefin film material of the present invention both can realize that the strong hot pressing of cohesive force was compound with paper or the paper that is printed with printing ink, can avoid the pollution of adhesive again to environment, simultaneously can discharge anion and active oxygen, impel the microorganism in the air ambient, the effect that organic compound molecule produces oxidation Decomposition, play the effect that purifies air, improves environment, help health.
The present invention relates to a kind of compound polyolefin film that can discharge anion, this film comprises three-decker at least, be upper epidermis, intermediate layer and following top layer, the intermediate layer is polypropylene or polyethylene layer, following top layer is to realize the compound thermal synthesis layer of hot pressing with paper or preprinted paper, it is characterized in that: described top layer down is modified by maleic acid anhydride graft thing or both blends or the ethylene-vinyl acetate copolymer of ethylene-alpha-olefin copolymer, ethylene-alpha-olefin copolymer; Upper epidermis is polypropylene or the polyethylene that contains the anion releasing agent, and the component of described anion releasing agent is:
The tourmaline micro mist is the silicate 84～90% of B, Al, Si, Mg, Mn, Zn, Ti
The far infrared micro mist is one or more mixtures 4～8% of ZrO2, ZrSO3, SiO2
Fine titanium dioxide powder 1～2%
The fineness of above-mentioned micro mist: D90≤0.80 μ m.
Above compound belongs to basic chemical industry product of the prior art, all can buy from the market.
Because polyolefin film of the present invention is mainly used in the compound product of paper, at the handling characteristics of this product, promptly this product belongs to the article that contact with staff, and the present invention has done further selection to the component of its thermal synthesis layer and anion releasing agent.
Compare with the technical scheme of Chinese patent ZL 03115757.2, in the application's film, improved the content of tourmaline micro mist, strengthened it and produced the performance of its hydroxyl anion and active oxygen, to adapt to the instructions for use of paper joint product.
The negative ion concentration that the utility model film that uses the EB13 ion detector of Japanese ECO-HOLISTIC company to record is produced is above 1000/second/centimetres
3, the normal direction emissivity of sample is greater than 0.8.This performance can guarantee that the product after compound in use discharges enough hydroxyl anion and active oxygen.
