A nano-porous material energy absorption structure packaged by high polymer materials comprises one-layer or multi-layer polymer material outer shell and nano-porous material mixed liquid packaged in the polymer material outer shell. The nano-porous material mixed liquid is formed by the fact that nano-porous materials and non-infiltrating liquid are mixed, and the maximum mass ratio of the nano-porous materials and the non-infiltrating liquid is 3:1. The nano-porous material is zeolite or porous silicon earth or nano-porous metal or nano-porous metal oxides or a carbon nano tube or activated carbon or nano-porous polymer materials. The non-infiltrating liquid is water or an inorganic salt solution or an organic solution or an oil-based solution or liquid metal or a rubber matrix. The polymer material outer shell is made of rubber or polyethylene or chloroethylene. According to the nano-porous material energy absorption structure packaged by the high polymer materials, energy is converted into solid-liquid two-phase surface tension, friction force and deformation energy of the polymer materials, so that energy absorption is effectively improved, the structure is simple, meanwhile, the weight is relatively low, and mass production and application are facilitated.
Description
Technical field
The present invention relates to a kind of endergonic structure, be specifically related to a kind of nano-porous materials endergonic structure that utilizes macromolecular material encapsulation.
Background technique
Up to now, most of energy-absorbing materials are " soft material ", comprise fiber reinforced high polymer, honeycomb metal (aluminium)/foamed material etc.These materials, in the time being subject to external load, by the principle (large deformation, flexing, slabbing, fracture, friction etc.) of " multiple spot effect ", come energy and stress wave that impact-absorbing brings, thus protection object construction.These materials can be realized preferably energy-absorbing effect in the time being subject to linearity, low velocity impact, but, high speed impact non-linear once be subject to even repeatedly impacted, its energy-absorbing effect will significantly decline, main cause be stress area and the material response time oversize.
Along with going deep into of nano science research, relevant scholar has been found that and confirms that nano composite material can absorb energy by following three aspects both at home and abroad, thereby reaches the object of protection and protection impact failure:
(1) flexing: nano composite material, because its microstructure has the nanometer of being of a size of, therefore can reach under high speed impact, and microstructure unit has time enough to respond with the forward position of corresponding Reeb, space; In this simultaneously, in the shear band that the part " ruckbildung " occurring in traditional material endergonic process produces, the microscopic units of nano composite material can produce part " sclerosis ", thereby guarantee homogenizing rapidly of material space around, the potential of the buffering stress wave of material is brought into play.But buffering stress wave only can be dealt with the high speed of small size and collide, and collides the damage being brought and be not sufficient to absorb energy finally to alleviate large size.
(2) fracture or cracking: nanometer material is in the time being subject to load, and in a large amount of endergonic situations, nanofiber and particle meeting and matrix stripping, produce cracking phenomena.Because the energy of cracking phenomena loss is more, thereby reach energy-absorbing object.In addition the microscopic units having due to nanometer material, exceeds several orders of magnitude than traditional material.Therefore a lot of material cell participate in fracture, will consume a large amount of energy.But nano composite material is due to adding of compound phase of easy generation embrittlement, and make the interface of most nano particles and matrix be difficult to cracking, reduced energy-absorbing efficiency.
(3) material internal friction: take nano-porous materials as representative, its hole ratio can reach 30%～90%, and the surface area of material is approximately 300～2000m
2/ g.Internal material particle is being subject to telling while impacting and can moving at material internal, and now the exhibiting high surface of material internal is long-pending can rub, and is heat energy by kinetic transformation, reaches the effect of energy dissipation and absorption.Then under impulsive load, can there is permanent flexing in its hole, and after this material cannot be resisted new impact, causes it to reuse.
Summary of the invention
The problem existing in order to solve above-mentioned prior art, the object of the present invention is to provide a kind of nano-porous materials endergonic structure that utilizes macromolecular material encapsulation, by energy dress being changed to surface tension that solid-liquid two is alternate and the energy of deformation of frictional force and macromolecular material, thereby effectively raise the absorption of energy, and simple in structure, weight is also relatively light simultaneously, is convenient to mass production and application.
In order to reach above object, the present invention adopts following technological scheme:
A kind of nano-porous materials endergonic structure that utilizes macromolecular material encapsulation, comprise one or more layers macromolecular material shell 2 and be encapsulated in the nano-porous materials mixed solution 1 in macromolecular material shell 2, described nano-porous materials mixed solution 1 is for nano-porous materials and non-infiltration liquid mix, and the biggest quality of described nano-porous materials and non-infiltration liquid is than being 3:1; Described nano-porous materials is zeolite, porous tripoli, nano porous metal, nano porous metal oxide, carbon nano-tube, active carbon or nanoporous polymer material.
Described zeolite is ZSM-5 zeolite, Beta zeolite or mordenite.
Described nanoporous polymer material is nano-cellulose, nanometer Kafra fiber, nanometer porous rubber, nano level modified rubber, nanometer natural plastics or nanometer synthetic plastic.
Described nano porous metal is nano porous copper, nanoporous nickel, nanoporous aluminium, nano-porous gold, nano-porous silver, nanoporous platinum, nanoporous iron or nanoporous titanium.
Described nano porous metal oxide is porous ferric oxide nanosphere, porous magnesia nano particle, porous aluminum oxide nano ball, porous copper oxide nanosphere, porous oxidation calcium nano, porous oxidation silver nano-grain or porous zinc bloom nanosphere.
Described non-infiltration liquid is water, inorganic salt solution, organic solution, oil base solution, liquid metal or colloid.
Described oil base solution is alkyl oil solution, alkyl oil solution or coal-based oil solution.
Described colloid is alumine hydroxide colloid, siliceous colloid or starch-hydrocolloid.
Described inorganic salt solution is sodium chloride solution, Klorvess Liquid, magnesium chloride solution, sodium carbonate liquor or aqua calcis.
Described organic solution is phenyl solution, ketone group solution, alcohol based sols or carboxyl solution.
Described liquid metal is mercury, liquid lead or liquid aluminium.
The material of described macromolecular material shell 2 is rubber, modified rubber, natural plastics or synthetic plastic.
In the time that the nano-porous materials endergonic structure after encapsulation is collided or impacts, it is large that the pressure that non-infiltration liquid is subject to will become, when pressure is crossed after a critical value, non-infiltration liquid will overcome capillary resistance and enter in nanometer material hole, and the required frictional force overcoming of nano-fluid can further increase the absorption of energy.By bearing the pressure of part, there is resiliently deformable in macromolecular material shell simultaneously, thus absorption portion energy.This process be actually by mechanical energy change into solution solid-the alternate surface tension of liquid two and the process of frictional force and macromolecular material elastic deformation energy.
Compared to the prior art, the present invention has the following advantages:
(1) when this nano-porous materials endergonic structure is collided or when impulsive load, make full use of the huge specific surface area of nanometer material and the elastic deformability of macromolecular material, by energy dress is changed to solid---the surface tension that liquid two is alternate and the energy of deformation of frictional force and macromolecular material, thereby the absorption that has effectively improved energy.
(2) by changing solid-phase (as material category, hole size or hole structure) or the liquid phase (as class of liquids) of nano-porous materials; can effectively control solid---surface tension and frictional force and initial working pressure that liquid two is alternate, make this structure can extensive use and all kinds of crash protection.
(3) due to the good elastic deformability of macromolecular material, after unloading, it can return to the situation before use, and now fluid will flow out nano pore, and this nano-porous materials structure can be reused.
(4) due to the flowable of nano-fluid, in the time using macromolecular material to encapsulate, can, by changing the profile of this nano-porous materials endergonic structure, facilitate the use of this structure in all kinds of crash protections.
(5) lower cost for material that this nano-porous materials endergonic structure uses, and structural design is simple, and quality is also relatively light simultaneously, is convenient to mass production and application.

And after unloading, the deformation energy of macromolecular material shell constantly discharges, simultaneously solid---the surface of liquid interface savings can constantly discharge, and overcomes liquid flowing resistance and acting to external world.Therefore be the process that deformation energy and surface can change into heat energy and external mechanical energy, can be expressed as:
ΔE
T 2+ΔE
S 2=ΔE
D 2+ΔW
2 （2）
Wherein Δ E
s 2for the surface energy that the liquid process of oozing out discharges, Δ W
2for liquid oozes out process work to external world, Δ E
d 2for the energy that power that liquid is hampered in the process of oozing out consumes, Δ E
t 2for the elastic energy of deformation of macromolecular material shell release.
What certainly, equation (2) was described is the situation that liquid oozes out duct completely.Can be not enough to overcome for surface and ooze out required consolidating---liquid friction energy completely, liquid may residue in duct, now can be expressed as:
ΔE
T 2+ΔE
S 2>ΔE
Dr 2+ΔW
r 2 （3）
Wherein Δ E
dr 2for partially liq oozes out the friction energy of actual dissipation, Δ W
r 2for partially liq oozes out external actual work.Be that the part surface that load phase absorbs can will become the endergonic part of this structure, uninstall process can not discharge this part energy.If all remaining in duct, the liquid in all infiltrations duct do not flow out Δ E
dr 2=Δ W
2=0.
Visible by above-mentioned analysis, whether liquid residues in duct and depends primarily on Δ E
s 2with Δ E
d 2.According to Gibbs Surface Energy Formulae Δ G=σ | cos θ | Δ Ω, surface can Δ E
s 2depend primarily on solid---light-liquid interfacial tension σ, wrapping angle q, and the surface size Δ Ω forming.
Similar with it, there is Young's equation P
l=(2 σ/r) | cos θ |, wherein r is the effective radius in duct.Visible infiltration pressure and the final surface forming can depend primarily on the type of duct and liquid.
As shown in Figure 1, for the existing endergonic structure utilizing after piston structure encapsulates nano-porous materials, comprise hollow cavity 6, in hollow cavity 6, be filled with zeolite mixed solution 3, cavity lid 5 is set on hollow cavity 6, load 1 directly imposes on zeolite mixed solution 3 by piston rod 4, between piston rod 4 and cavity lid 5, be also provided with seal ring 2, this endergonic structure is in the time being impacted or collide, solution liquid easily spills, this structure is more complicated simultaneously, is not suitable for being applied in the structure being easily hit or collide.
Embodiment one
As shown in Figure 2, a kind of nano-porous materials endergonic structure that utilizes macromolecular material encapsulation of the present embodiment, this nano-porous materials is ZSM-5 zeolite, its average pore size is 0.5nm, after being mixed with water, it is configured to the solution that concentration is 1:1, the macromolecular material shell 2 that uses PVC＝polyvinyl chloride to be made encapsulates nano-porous materials mixed solution 1, consolidate-light-liquid interfacial tension of this nano-porous materials endergonic structure can be used as constant, and now the wrapping angle at solid-liquid interface depends primarily on the hydrophobicity in duct.In the situation that infiltration volume is identical, the hydrophobicity of ZSM-5 zeolite material is strong, and wrapping angle is large, and infiltration pressure is large, and surface can be also large, otherwise both all reduce.
Simultaneously under nanoscale, can not regard fluid as continuous state analysis, the mobile suffered resistance of fluid under nano-confined space is also no longer the viscous force that traditional sense upper stream has, and should be certain interaction between water molecule and solid duct crystal.When water molecule flows in nano pore, duct inwall and " shearing stress " between near the water molecule inwall of duct effect are water molecule mobile suffered Main Function power in duct.This " shearing stress " effect is relevant with the hydrophobicity of ZSM-5 skeleton, relevant with its aperture and flow velocity on the other hand on the one hand.The hydrophobicity of ZSM-5 skeleton is stronger, and it is just less to the active force of water molecule; And aperture is less, just fewer with silicon-oxy tetrahedron or the aluminum-oxygen tetrahedron of water molecule vicinity on skeleton, just less to the active force of water molecule.And the not enough 1nm in the aperture of ZSM-5 zeolite, and after heat treated, hydrophobicity is very strong, and therefore water molecule can slide very swimmingly in duct, and suffered resistance is very little.
Comprehensive analysis adds uninstall process, and no matter whether uninstall process liquid oozes out, and all has Δ E according to energy conservation
s 1=Δ E
s 2, the energy that macromolecular material shell absorbs and discharges simultaneously should equate, i.e. Δ E
t 1=Δ E
t 2.And the ZSM-5 aqueous solution can all ooze out at unloading phase, have:
Can obtain: Δ W
1-Δ W
2=Δ E
d 1+ Δ E
d 2.Being the whole energy conversion process that adds uninstall process is converted into the heat that in the process of oozing out, water molecule and duct " friction " produce for: extraneous work.
Because this structure " friction " dissipation energy is in use less, be only Δ E
d=7.460J, negligible, therefore this structure can be used as crash energy absorption equipment, is similar to a spring with buffer function, especially, under percussion, can significantly reduce the peak value of power, plays a protective role.Water molecule infiltrates the surface energy Δ E that ZSM-5 zeolite duct forms simultaneously
s=174.587J, then consider the huge deformation energy that the distortion of macromolecular material shell elasticity absorbs, this structure has realized a large amount of energy transfers in the time being collided or impact as seen, can reach good protective action to object construction.This protective action can relatively finding out by the stress-strain curves figure to Fig. 3 and Fig. 4: as can be seen from Figure 3 in the time that stress reaches 150MPa, strain is only in 0.3 left and right, and Fig. 3 is the stress-strain curves figure after endergonic structure shown in Fig. 1 loads; Fig. 4 is the stress of the present embodiment endergonic structure in loading procedure---strain curve, in the time that stress reaches 150MPa left and right, has one section of obvious platform as seen, and strain simultaneously can reach 0.5 left and right.Comparison diagram 3 and Fig. 4, can find out that, under identical stress, the energy that the present embodiment endergonic structure can absorb is more, and therefore visible structure of the present invention has good energy-absorbing effect and application scenario.
If " friction " of this structure dissipates little of ignoring, it is certain oozing out the required external force of process, is not therefore considering that aperture has under the condition of certain distribution, and the platform section of curve will be strict horizontal line.External force exceedes this value, and water molecule will infiltrate; Lower than this value, water molecule will ooze out.
