The height of the honeycomb paper core is the same as that of the EVA foaming buffer layer, and the thickness of the aerogel layer is 2-6mm. The high-buffer obstructing composite packaging board has good compression resistance and buffer performances, excellent moisture protection and heat insulation properties and certain rebound elasticity and can meet the relatively high requirements on moisture protection, heat insulation and buffer performance.
Description
Technical field
The utility model relates to a kind of composite packing paper sheet material material, especially relates to a kind of composite packing paper sheet material material with excellent buffering and barrier.
Background technology
In packing, buffering is a very important performance, also is the attribute that most of packing all needs, and using the most widely, package buffer material is polyethylene EPE and styrofoam EPS.Though they have very excellent in cushioning properties can with stability, preparation is simple.But the material non-degradable can cause serious white pollution, and also can produce pollution in preparation process.So this traditional padded coaming is prohibited in part country.The substitution material that searching has excellent properties then becomes the task of top priority.At present, most typical substitution material is corrugated board, honeycomb cardboard, and paper mould etc. all extensively are used to the buffering package field.Especially in recent years the honeycomb cardboard of Xing Qiing has shock-absorbing capacity preferably, the structural design of honeycomb cardboard simulation honeycomb, be that numerous hollow three-dimensional hexagon is connected into a whole stressed member with adhering method, make honeycomb cardboard have fine many compressive properties.Simultaneously, honeycomb has increased the compressible performance of cardboard, makes it have good shock-absorbing capacity, and its absorption and thickness to energy is proportional, and more thick shock-absorbing capacity is more good.But easily to the product surface wearing and tearing, humidity effect is big for honeycomb cardboard, and overload demobilization property is poor, and processing is difficult, bad cutting, and the vertical direction shock-absorbing capacity is relatively poor, and resilience is relatively poor, and barrier property still remains to be improved.At these shortcomings, and make every effort to obtain having the more environment-friendly paperboard material of excellent properties, the utility model is at the advantage of honeycomb cardboard and the defective used separately, and it is compound that itself and difference in functionality material layer are arranged in pairs or groups, and can obtain having excellent resiliency, waterproof, heat insulation combination board material.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming that existing cardboard amortizing packaging material honeycomb cardboard exists, and a kind of have good resistance to compression and shock-absorbing capacity are provided, excellent protection against the tide and thermal insulation, and have certain elastic combination board material.Can be applicable to packaging board material field moistureproof, heat insulation and that shock-absorbing capacity has higher requirements.
The purpose of this utility model is achieved through the following technical solutions: it comprises outer facial tissue, honeycomb paper core, sandwich paper, EVA foamed damping layer, bottom facial tissue.Being honeycomb paper core between described outer facial tissue and the sandwich paper, is EVA foamed damping layer between sandwich paper and the bottom facial tissue; Be further characterized in that and be provided with the flexible carpet veneer of aeroge nano-pore between EVA foamed damping layer and the sandwich paper.Honeycomb paper core is identical with EVA foamed damping layer height, and aerogel layer thickness is 2-6mm.
Described honeycomb paper core cross sectional shape is regular hexagon or rhombus.
Described EVA foaming layer is to be major ingredient with the ethylene-vinyl acetate copolymer, and adds other auxiliary materials, as AC series blowing agent, and calcium carbonate superfine powder, bridging agent, foamed promoters etc. prepare foaming plate by press foaming technology.The EVA expanded material has excellent resilience, resistance to ag(e)ing, crack resistance, and its performance can be carried out inching according to the difference that adds auxiliary material.The abscess open-close pore structure of EVA expanded material all can, cell size is advisable with 0.05-0.2mm.
Described aerogel heat-proof flexible mat is based on the nanometer titanium dioxide silica aerogel, and silica is compound in the fiber, is prepared from by special process.The hole of nanoscale has distributed in the aeroge flexible mat, performance characteristics specific as follows: one, thermal insulation is good, thermal conductivity factor is little, the nanoporous aerogel flexible mat is the minimum heat-barrier material of present known thermal conductivity factor, thermal conductivity factor is about 0.018W/ (m.k) during its 25 ° of C, and long-term serviceability temperature can reach 400 ° of C.Two, the nanoporous aerogel flexible mat has whole hydrophobicity, has good water proofing property.Three, different with traditional aerogel plate, the aeroge flexible mat has flexibility and intensity preferably, even structure sheaf produces the crack, also can not cause the integral body fracture of aeroge nano-pore flexible mat, thereby cause heat insulation and water proofing property.Four, this aeroge flexible mat has green non-poisonous characteristics.Five, this aeroge nano-pore flexible mat quality is very light, and density is lower than 200Kg/m
3, can not increase the weight of the weight of paper board material.
Nano silicon aeroge aperture in the described aerogel heat-proof flexible mat is preferably 1-100nm.
Described outer facial tissue, bottom facial tissue can adopt brown paper, and sandwich paper can adopt fluting medium.
The available adhesive of bonding between honeycomb cardboard and facial tissue and the sandwich paper can be the corrugated board amylan, available roller gluing.
Sandwich paper and aerogel layer can adopt adhesive between aerogel layer and the EVA foaming layer, bind as thermosetting acrylic class adhesive.
The height of the utility model buffering barrier composite packaging plate combines the good shock-absorbing capacity of honeycomb cardboard, the resilience that the EVA expanded material is good, and resiliency, and in conjunction with the barrier of aerogel layer excellence.This composite plate is applicable in electronics, food, the accurate preparation class buffering, waterproof, protection against the tide, heat insulation, packaging field with high requirement.
