Abstract
The utility model provides a composite packaging film high in antishock performance. The composite packaging film is formed by compositing nine layers and sequentially comprises a blocking layer I, an adhesive layer, a PET film layer I, a sandwich fabric layer, a PET film layer II, an adhesive layer II, a blocking layer II, a silica gel layer and a PET release film layer from outside to inside. The composite packaging film is characterized in that the fiber fabric layer is made of synthetic fabrics filled with nanometer dispersing materials inwards, the area of the fiber fabric layer is smaller than that of the PET film layer I and that of the PET film layer II, the portions, without the fiber fabrics, of the edge of the PET film layer I and the edge of the PET film layer seal the fixed fiber fabric layer through hot melt adhesive, and the blocking layer I and the blocking layer II are nylon film layers. The composite film has the excellent antishock performance, is capable of being fixed to the surface layer of an object needing to be protected, and easy and convenient to use, and can be applied to the protection field of plastic or electronic products low in transparency requirement while high in antishock requirement.
Description
Technical field
The utility model relates to a kind of pad pasting, relates in particular to a kind of pad pasting with excellent impact resilience.
Background technology
The existence of pad pasting is for protector compound, and general pad pasting only applies to the screens such as mobile phone screen, computer screen, for the protection of screen, is not worn and has certain surge protection.And it is generally less for the pad pasting protection of other article.In commodity; especially high-grade goods as the protection of frangible section in electronic product, breakaway glass product field be a very large problem; whole anti-impact protection will take a large amount of volumes and need higher cost, therefore as can local protection will greatly reduce packing cost and can widen the range of application of protection.The utility model provides a kind of pad pasting with excellent impact resilience, and rete is thin, conveniently easily pastes, and can directly be affixed on the frangible region of required protection.
Utility model content
The technical problems to be solved in the utility model is, overcomes the above-mentioned defect that prior art exists, and provides a kind of frivolous, is simple and easy to paste, and has the packing pad pasting of excellent anti-impact.
The utility model solves the technical scheme that its technical problem adopts:
A high-impact composite packaging pad pasting, compound and obtain by 9 layers.Comprise successively from outside to inside barrier layer I, adhesive layer, PET rete I, fiber fabric layer, PET rete II, adhesive layer, barrier layer II, layer of silica gel, PET release film layer.
Described barrier layer I and barrier layer II are that nylon rete is for to obtain by nylon blow molding.Nylon membrane has excellent barrier and mechanical property, and has good wearability.
Described fiber fabric layer is by synthetic fibers as polyethylene fibre, and the braidings such as polyester fiber form, and is filled with nano-dispersed thing in fabric.
Described nano-dispersed thing is comprised of decentralized medium and nano-dispersed thing.Wherein decentralized medium is organic matter or the organic solution with viscosity higher, as glycerine, ethylene glycol, polyethylene glycol etc.Nano-dispersed thing is spherical organic and inorganic particulate, comprises nanometer SiO
2microballoon, nano pipe/polyhenylethylene, poly (methyl methacrylate) micro-sphere etc., its diameter is between 20nm-1000nm.The solid-liquid volume ratio of suspension is between 32%-54%.When being subject to impulsive force, the spherical nano particle in suspended dispersed liquid will be assembled rapidly, and " shearing retrogradation " phenomenon occurs, apparatus with shock absorbing, and after impact finishes, this gathering disappears, and suspension becomes dispersion normality again.
Except fiber fabric layer, all the other each layer of area shapes are identical, and fiber fabric layer is positioned at PET rete I and PET rete II, its Edge Distance PET rete I and PET rete II edge 1-2cm.EVA PUR heat-seal fiber fabric layer is sentenced without fabric in PET rete I and PET rete II edge.But due to heat-sealing unsealing fiber fabric layer upper and lower surface, nano-dispersed material is wherein mobile to give full play to its anti-impact effect therein.
Between described barrier layer I and PET rete I, all bonding by adhesive layer between PET rete II and barrier layer II.Adhesive phase can be esters of acrylic acid nonpoisonous adhesive.
The thickness of described barrier layer I is 0.05-0.2mm, the thickness of adhesive layer is 0.05-0.1mm, the thickness of PET rete I is 0.1-0.2mm, the thickness of fiber fabric layer is 0.4-01.2mm, the thickness of PET rete II is 0.1-0.2mm, and the thickness of adhesive layer is 0.05-0.1mm, and the thickness of barrier layer II is 0.05-0.2mm, the thickness of layer of silica gel is 0.05-0.1mm, and the thickness of PET release film layer is 0.1-0.2mm.
Feature of the present utility model is, give full play to the excellent erosion-resisting characteristics that fiber fabric layer has, the intensity that coordinates PET rete, meanwhile, thus the existence by barrier layer has intercepted entering of aqueous vapor have been avoided the dilution of nano-dispersed thing in fiber fabric layer and then has affected its erosion-resisting characteristics and service time.Layer of silica gel, PET release film layer has played with tearing with the effect of pasting.
Accompanying drawing explanation
Fig. 1 is the utility model one example structure schematic diagram.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
With reference to Fig. 1, a kind of high-impact composite packaging pad pasting, compound and obtain by 9 layers.Comprise successively from outside to inside barrier layer I1, adhesive layer 2, PET rete I3, fiber fabric layer 4, PET rete II5, adhesive layer 6, barrier layer II7, layer of silica gel 8, PET release film layer 9.
Described barrier layer I1 and barrier layer II2 are that nylon rete is for to obtain by nylon blow molding.
Described fiber fabric layer 4 is dacron fabric.In fabric, be filled with nano-dispersed material.Described nano-dispersed material is comprised of decentralized medium and nano-dispersed thing.Wherein decentralized medium is glycerine, and nano-dispersed thing is nanometer SiO
2microballoon, its diameter is between 50nm-200nm.The solid-liquid volume ratio of suspension is 52%.
Except fiber fabric layer 4, all the other each layer of area shapes are identical, and fiber fabric layer 4 is positioned at PET rete I3 and PET rete II5, its Edge Distance PET rete I3 and PET rete II5 edge 1.5cm.EVA PUR heat-sealable fiber tissue layer is sentenced without fabric 4 in PET rete I3 and PET rete II5 edge.
The thickness of described barrier layer I1 is 0.1mm, the thickness of adhesive layer 2 is 0.06mm, the thickness of PET rete I3 is 0.15mm, the thickness of fiber fabric layer 4 is 0.8mm, the thickness of PET rete II5 is 0.15mm, and the thickness of adhesive layer 6 is 0.06mm, and the thickness of barrier layer II7 is 0.1mm, the thickness of layer of silica gel 8 is 0.08mm, and the thickness of PET release film layer 9 is 0.15mm.
