Abstract
The utility model relates to multifunctional composite film, which comprises a fibre upper layer, a fibre lower layer which is thermally sealed with the upper layer, and sodium polyacrylate type ultrafine particles positioned between the fiber upper layer and the fiber lower layer. The utility model can be made into multiple layers, and the combination of the utility model with other materials can be realized. The utility model has the advantages that favorable hygroscopic effect can be realized, because the ultrafine particles are covered by the fiber layers, large air contact area can be realized, high material using ratio can be realized, face type hygroscopic method is adopted by the composite film, and water content in a package can be fully absorbed. The utility model can be directly made into packaging bags or can be stuck at inside of packaging bags, space occupation is little, erroneously eating can be avoided, and the utility model can be used as preservative film after saturated water absorption.
Description
The utility model relates to a kind of high-mobility, multipurpose, wheeled vehicle complex film.
At present, widely used desiccant is an inorganic particulate matter on the market, and particulate matter need add packaging bag when using, both accounted for the packing material inner volume, and caused people to eat by mistake, misapply again easily, the injury health, and because of water-absorption surface is little, water-taking efficiency is not high, is difficult for again reclaiming using, in addition, still do not have a kind of high-mobility, multipurpose, wheeled vehicle film at present, film has only a kind of function mostly, therefore is necessary to provide a kind of high-mobility, multipurpose, wheeled vehicle complex film, this film has functions such as drying, and easy to use, drying efficiency is high.
The purpose of this utility model provides a kind of high-mobility, multipurpose, wheeled vehicle complex film, this membrane structure novelty, and area of contact is big, and is easy to use, and range of use is wide, effective.
For achieving the above object, the utility model is taked following design plan: a kind of high-mobility, multipurpose, wheeled vehicle complex film, comprise the fiber upper strata, and with the fiber lower floor of upper strata heat seal, and the sodium polyacrylate microparticle between fiber upper strata, fiber lower floor.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the utility model front view
Fig. 2 is the A-A section-drawing of Fig. 1
As shown in Figure 1 and Figure 2,1,3 is fiber upper strata, fiber lower floor, this fiber can use rayon nonwoven fabrics, this fiber nontoxic, certain ductility, certain intensity, pore-solids ratio height are arranged, and permeability is good, the about 1-2mm of thickness, 2 is the sodium polyacrylate microparticle, have three-dimensional cross-linked net structure, be graininess, all there is sale on ground such as this microparticle Shanxi, Jiangsu.Its particle diameter is decided according to the film water absorbing capacity, grain size between 80 orders-120 order, this particle good hygroscopicity.
All can sprinkle polyacrylic acid again and receive the class microparticle outside fiber upper strata or fiber lower floor, add a rayon layer at the microparticle layer, form a complex film again through hot pressing, same, this complex film can be that multilayer is overlapping.
Can heat seal plastic sheeting or paper in the fiber upper strata of complex film outermost or fiber lower floor, be coated with a non-drying glue layer on plastic film or the paper, non-drying glue layer covers parting paper outward, for example is coated with silicone oil paper, is affixed on when needing in the container, makes desiccant and uses.In addition, product of the present utility model can directly be made packaging bag.
Can make preservative film after this film suction is saturated and use, be used to adorn fruit and vegetable using etc.
The job operation of this film is: spread fibrage (rayon nonwoven fabrics) in mould, all spread the sodium polyacrylate microparticle above, press a rayon nonwoven fabrics above it, through hot-forming, hot pressing temperature is less than 180 ℃, this fiber upper strata, lower floor's heat seal, solid shape particle is between two layers, and for uniform particles being distributed and avoiding skidding off to side, mould can be made a plurality of grid-like, the section of lattice is square, triangle or other geometric configuratioies etc., its fiber the upper and lower corresponding recesses, this groove falls into the film of this structure for particle, good permeability (fiber is not easy to concentrate and is even), not only particle is easily fixing, and has reduced grain breakage, according to fiber layer thickness and particle grain through varying in size, the surface configuration of this complex film of processing back can be smooth, also can be waveform.
The utility model has the advantages that:
1, moisture absorption efficient height, because microparticle covers with film, thereby itself and contact with air area maximum, profit Use the rate height; This composite membrane is big with planar moisture absorption and contact with air area, can absorb rapidly gas in the packing material comprehensively Moisture in the body in residual moisture and the infiltration packing material makes packing material can not form moisture film.
2, because it can be connected with packing material, account for less the packing material inner space, also be difficult for causing and eat by mistake, Can also improve packing material intensity.
3, fiber and High molecular material (sodium polyacrylate) can with plastic packaging bag reclaiming simultaneously, free from environmental pollution.
4, since its can be integral with the packing material adhesion, after the drying can with original packing thing repeated use, save use cost.
5, production technology is simple, and is easy to use.
6, of many uses, absorbing water can be used as fruit, Vegetable Preservation film, one-object-many-purposes after saturated.
7, can make multiple complex film with paper or plastics.
