A high internal phase emulsion having an emulsion stabilizing surfactant, one or more insoluble fillers, at least 70 volume percent of a discontinous internal phase; and less than 30 volume percent of a continuous external phase containing one or more vinyl polymerizable monomer(s). Polymerizing the water-in-oil high internal phase emulsion produces an open-cell porous polymeric material having insoluble fillers incorporated into its polymeric backbone.
Description
The present invention relates to High Internal Phase Emulsion and by its prepared porous polymer material.
Emulsion is discontinuous or isolated dispersion of particles body, this discontinuous or isolated particle be commonly referred to as external phase or " outside " " interior " phase in mutually.Emulsion both can be oil-in-water (oil/water) type, and phase and water-based foreign minister in the oiliness are arranged, and can be again water-in-oil (water/oil) type, and phase and oiliness foreign minister in the water-based are arranged.It is interior phase more than 70% or 70% that emulsion can contain volume fraction, and they are commonly referred to as High Internal Phase Emulsion (HIPEs).The volume fraction of phase can be up to 90% in this emulsion, and often reaches 95%, it is reported that some HIPEs water volume fractions can reach 98%.
An early stage application of High Internal Phase Emulsion (HIPEs) is as the solid suspension medium, as U.S. Patent No. 3974116 disclosed examples.The high static viscosity of HIPEs can prevent particle precipitation, and in a similar application, HIPEs is used as and transports the transmitting fluid of particulate by pipeline, as U.S. Patent No. 3617095 disclosed examples.The high static viscosity of emulsion can prevent the solids sedimentation, but under shearing action the viscosity degradation of emulsion, can make the pipeline that passes through of emulsion highly effective by pump pressure.Because the particulate resemble the polynite can be used to breakdown of emulsion, therefore can make the ability of particle suspension in HIPEs seem somewhat wondrous, as K.J, Lissant is in " emulsion and emulsion technology " first part " preparation of emulsion and breakdown of emulsion ", the 122nd～123 page (1974).
The application of High Internal Phase Emulsion (HIPEs) aspect the preparation porous polymer material is also well-known, for example all describes to some extent at U.S. Patent No. 5210104, No.5200433, No.4536521, No.4788225, No.5147345, No.5331015, No.5260345, No.5268224 and No.6318554.In described HIPEs, typical oiliness foreign minister is made of polymerisable vinyl monomer (for example 2-EHA and vinylbenzene) and cross-linking monomer (as Vinylstyrene).Be to constitute mutually in the typical water-based by water, radical initiator (if not at oil phase) and ionogen.In order to form stable emulsion, in oil phase, adding tensio-active agent before the emulsification.Generally being used for the tensio-active agent of stable emulsion for example comprises nonionic surface active agent, as sorbitan ester (for example sorbitan monooleate and sorbitan mono-laurate).Other known stabilization tensio-active agent has Polyglycerine fat family ester, and is disclosed as United States Patent (USP) 5500451.
By the prepared porous polymer material of HIPE in a lot of fields all of great use.For example United States Patent (USP) 5260345,5268224,5331015 discloses the absorbing material that the hipe foam material is used as the diaper based article.The excellent characteristics that the HIPEs foam materials is used as absorbing material is its high void volume rate and low density, and high liquid absorption capacity is provided.If the density of supposition polymkeric substance is 1g/cc, interior is about 49 gram water/gram foam materialss (gram/gram receptivity) for the liquid absorption capacity of the foam materials of the HIPE of 98wt% preparation mutually.Both can also improve the gram/gram receptivity of foam materials by reduction density by improving the abscess rate of foam materials.On history, change one of them factor, then another factor becomes thereupon.That is to say that improving foam materials abscess rate just makes density reduce.The abscess rate is by the decision of the internal-phase ratio of emulsion example, and the internal-phase ratio example is high more, and the final abscess rate of foam materials is high more.Can polymerization how much enter foam materials but can reach many height as for the internal-phase ratio example mutually with interior, this is limited.Another method that improves hipe foam material abscess rate is that inert oil is added the foreign minister, removes inert oil after the polymerization, stays the space in polymer wall and polymer support structure, but the collection and the handling problem of inert oil after must considering polymerization process.And improve the abscess rate thin supporting structure of generation on the foam materials wall easily, so just produce more weak foamy structure.Therefore if do not improve the internal-phase ratio example or do not use inert oil and can improve the gram/gram receptivity of hipe foam material, this will be very desirable.
The Another application of hipe foam material is the barrier material that is used as heat and sound.The application of this respect is for example disclosed in U.S. Patent No. 5633291.As lagging material, stoping heat is very important by insulating material.A kind of mode that heat passes material is radiation, and at this moment infrared wave directly reaches the other side by insulation layer.If add the infrared rays barrier material, the thermal radiation part just can be reduced or eliminate, and the heat-insulating capability of hipe foam material just can be enhanced.Lagging material and soundproof material general requirement are fire retardant materials, but because the hipe foam material is an organic materials, therefore inflammable.
Ideal method is to improve the gram/gram receptivity of hipe foam material and not improve internal-phase ratio routine or do not use inert oil.In addition, and another ideal method provides water-in-oil High Internal Phase Emulsion and porous polymer material prepared therefrom, adds the heat-proof quality that the infrared rays barrier material is strengthened the foam materials product therein.If can provide the hipe foam material that adds fire retardant material then more satisfactory.
First aspect, the present invention is a kind of High Internal Phase Emulsion, contains the tensio-active agent of stable emulsion, soluble filler, volume fraction and is at least 70% interior phase and volume fraction less than 30% foreign minister, the foreign minister is contained one or more polymerisable vinyl monomers.
Second aspect, the present invention is the method for High Internal Phase Emulsion of preparation first aspect, this method comprises preparation foreign minister and Nei mutually, to wherein one mutually or add soluble filler in the two-phase, then under being enough to form the condition of emulsion with the foreign minister with Nei mix mutually.
The third aspect, the present invention is the method for High Internal Phase Emulsion of preparation first aspect, this method comprises preparation foreign minister and Nei mutually, water and oil phase is mixed being enough to form under the condition of emulsion, adds soluble filler then in emulsion.
Fourth aspect, the present invention is a kind of open cell type porous polymer material, makes by the High Internal Phase Emulsion polymerization that makes first aspect.
The 5th aspect, the present invention is a kind of open cell type porous polymer material, mixes soluble filler in its polymer backbone.
We find, High Internal Phase Emulsion (HIPEs) not only can make containing under the situation of soluble filler, and can polymerization enter foam materials, and foam materials contains soluble filler in its polymer backbone.Though it is known to contain the HIPE of specific soluble filler, but we can prepare the HIPE that contains the insoluble filler of wide region more and they can be mixed among the HIPE with the polymerizable vinyl monomer, these fillers comprise the smectites clay, and the smectites clay it is reported and can destroy HIPE (referring to above-mentioned document).And HIPE can aggregate into the open cell type foam materials and still contain soluble filler, and this is beat all.In order to form the open cell type structure, in polymerization process HIPEs must be in to a certain degree breakdown of emulsion so that on cell wall, form perforate.But breakdown of emulsion can not too form and be separated.As mentioned above, known soluble particulate can breakdown of emulsion.Therefore, make the HIPE polymerization that contains soluble particulate form open-celled structure and do not form and be separated, this is beat all.
HIPEs of the present invention is very useful aspect the preparation polymer foams, and this polymer foams both can improve or reduce density, and need not improve or reduce the internal-phase ratio example of HIPE.
Polymer foams of the present invention also can be used for lagging material and sound-absorbing material, also can be used for liquid-absorbent.
Fig. 1 is that the acoustic attenuation spectrogram of embodiment 6 and the prepared foam materials of Comparative Examples B compares.
It is about 70% that the volume fraction of the interior phase of High Internal Phase Emulsion of the present invention (HIPEs) is higher than, more Preferably volume fraction is greater than about 90%, and most preferably volume fraction is greater than about 95%; Its Foreign minister's volume fraction is less than about 30%, and more preferably volume fraction is less than about 10%, optimum What select is that volume fraction is less than about 5%; And contain insoluble filler. Preferred HIPE is the oil bag Aqueous emulsion comprises phase and oiliness foreign minister in the water-based. Contain volume fraction and be 98% or higher water-based The HIPEs of interior phase can make by the present invention. The foreign minister comprises one or more polymerizable second Alkenyl monomer, preferably the foreign minister also comprises cross-linking monomer, the interior water that comprises mutually. Typically, Water-soluble radical initiator adds water. If the use oil-soluble initiator then adds oil Phase. In addition, HIPE also comprises surfactant and soluble filler.

Preferably, the HIPE emulsion contains at least a glassy state monomer and at least a rubber The attitude monomer. Do not want to be limited by theory, the rubbery state monomer is believed to give foamed material Pliability, and should have certain quantity adding to guarantee the goods that contain this foamed material Can bear compression, bending and torsion in worker, packing, shipment, storage and the use procedure. The glassy state monomer is believed to give the globality of foamed material with structure, and should have certain Quantity to guarantee that this foamed material is subjected to dynamic force and static force is done the time spent, can be with foam Minimum is down in tearing with broken damage envelope that material suffers. Generally speaking, glass The ratio of attitude monomer and rubbery state monomer is between 1: 25 to 1.5: 1, preferably at 1: 9 In 1.5: 1.
The best usage quantity of polymerizable vinyl monomer depends on several factors, as concrete Monomeric species. In general, the operating weight scope of polymerizable vinyl monomer be whole outside The 50%-100% of phase weight is more preferably 80%-95%, most preferably is 85%-93%.

According to the purposes of final foam materials, but the oxyhydroxide that preferred soluble filler is carbon black, graphite, metal-powder, metal, the hollow packing that resembles glass or ceramic microsphere, natural or synthesis of clay, millimicro filler, metal powder, contain the polymer powder functionalized, oily swellable filler as slight crosslinked polymer powder and water-swellable material such as crosslinking sodium polyacrylate just like the fire-retardant filler copolymerization filler of phosphorus, antimony, boron, bismuth and/or halogen such as acrylate.The oxyhydroxide that preferred soluble filler is carbon black, Graphite Powder 99, metal-powder, metal, ceramic microspheres, millimicro filler and granulated metal.Most preferred soluble filler is carbon black, graphite, hibbsite, magnesium hydroxide, ceramic microspheres, Clayton APA montmorillonite silicate clay and iron powder.
Soluble filler can change many performances of hipe foam material, comprises density, modulus, tensile strength, heat conductivity, flame retardant resistance and magnetic property.Typically, the adding of the soluble filler of single variety not only changes a kind of performance.For example, add density and the ferromagnetic property that comparatively large vol fractional iron powder will improve foam materials simultaneously.In the ordinary course of things, the soluble filler of larger amt reduces the tensile strength of foam materials easily.Loss of tensile strength may be because between polymkeric substance and the filler due to the more weak binding property.By add can with the filler of polymer network generation Chemical bond or mechanical bond, can offset reducing of tensile strength.An example is that most of coupling agent is well-known in this area with the surface property of coupling agents to improve filler.Known coupling agent comprises organic functionalized silicon compound, as vinyltrimethoxy silane and γ-propyl methacrylate base Trimethoxy silane; Titanium compound is as sec.-propyl three isostearoyl base titanic acid ester and trimethylammonium acrylic isopropyl ester base titanic acid ester.Methacrylate functionalized coupling agent effect can be better, because methacrylate based group participates in polyreaction.Another example is to adopt the acrylate functional filler, it in polymerization process can with monomer generation copolymerization.Can in organic monomer, can produce firm mechanical bond by the expansible filler, because pass the expansible filler grain during monomer polymerization.
The optimum quantum of utilization of soluble filler depends on series of factors, comprises HIPE or the desired use of polymeric hipe foam material has taken place and the type of the filler that uses.As previously mentioned, behind the adding filler, often more than a kind of foam performance changes.Must adjust the usage quantity of filler like this to reach estimated performance.For example, if expect the ferromegnetism high-density foam material, can produce the HIPE that contains a large amount of iron powders so.If but the ferromegnetism of expecting and do not wish to have high-density just can be used few many iron powders, perhaps prepare iron powder and be distributed in a thin layer, hollow low density filler laminate structure at another layer.Compare with other fillers, some fillers require higher concentration is arranged to obtain required performance.For example, the carbon black add-on during less than 15wt% just with the heat transfer property of remarkably influenced foam materials, but the ATH add-on must be about 30% or the higher flame retardant properties that just can make significantly improve.Therefore, the type decided of purposes and used filler best packing density.In general, the usage quantity of soluble filler can meet or exceed 100% of external phase volume.In broad filler scope, the usage quantity of soluble filler can reach 100% of external phase volume.In wideer filler scope, the usage quantity of soluble filler can reach 50% of external phase volume.In further wide filler scope, the usage quantity of soluble filler can reach 10% of external phase volume.In the wideest filler scope, the usage quantity of soluble filler can reach 1% of external phase volume.
