Description
The present invention relates to the preparation method of the multilayer insulating panel of ad hoc structure, thus plate of obtaining of method and uses thereof.
Many fields of economic activity need dividing plate cheaply.For example, in building and field of civil engineering, the heat-proof quality that is used for the plate of roof or various body of wall tasks is basic.In transportation, fields such as refrigeration are like this equally.In these were used, it was known using multi-layer sheet, and the one deck in the multi-layer sheet has heat insulating function.One or more other layers provide whole mechanical strength and suitable outward appearance may be provided.
(near highway, airport, noisy machinery etc.) also needs sound insulation value except that heat-proof quality under some environment.In order to reach this target, now designed the multi-layer sheet that between the top layer of non-expansive material, has expanding material (foam) core., in some cases, the mechanical performance deficiency that obtains, in addition, the bonding between foam and the external skins usually is unsatisfactory.
Patent US6,673,415 disclose a kind of structure that can address the above problem, and wherein in fact foam has been full of the unit of the honeycomb that is fixed in epidermis.This structure has required isolation and mechanical strength properties usually., prepare the mode of this structure, it comprises the honeycomb that at first prepares filled and process, sticks skin (epidermis) then on its surface, and this mode is also infeasible economically.And, it is individual from beginning with regard to known thorny task producing above-mentioned thick china with the plasticity honeycomb continuously with single step, the expansion of the composition of blowing agent has exothermic phenomenon and therefore described honeycomb is easy to take place unallowed distortion because contain, and this is known.
Now, shockingly find can obtain using the excellent product of plastic core and one-step method acquisition, wherein the material of filled honeycomb expands between two epidermises.Do not wish to be bound by a theory, applicant company believes that this is because due to the thermal conductivity that obtains gradually reduces during component foaming.
Therefore the present invention relates to the method that prepare multilayer insulating panel, and this multilayer insulating panel comprises porous core and two non-expansive material skins of the frothy honeycomb based on plastics of filling, and described method comprises the steps:
An outer introducing in the former with this plate;
Honeycomb placed on the described skin and with second skin introduce former together with the composition of the blowing agent that comprises injection;
The composition that comprises blowing agent expands;
Dividing plate is shifted out from former.
The prepared according to the methods of the invention plate can be flat or crooked basically.Term " substantially " is meant the example of the plate with surface undulation especially.
They mainly be (that is, dominant aspect volume) based on for example timber, the heat-barrier material of plastics etc., but the plate made based on non-heat-barrier material (for example metal) of exclusive segment not., preferred, plate of the present invention is mainly based on plastics.
As one special preferred, the plate that is obtained by method of the present invention is the multi-layer sheet with the core that comprises at least a honeycomb, this honeycomb is based on fills frothy plastics, this foam also is made of plastics.
" honeycomb " is intended to a kind of like this object of expression, it is flat basically (whole shape in blocks) or some bending a little, comprise cavity, that is to say the unit of the opening or the sealing of any cross section, be generally circle or hexagonal cross-section, its wall is substantially parallel and perpendicular to the surface of sheet from unit to another.
According to the present invention, (fully preferred by foam-filled honeycomb, that is to say at least 90 volume % or even 100 volume %, like this so that promote the adhesion strength of plate each several part) form the plate core at least in part. " foam " should be understood as that by interpolation and be called as the additive of " blowing agent " and material that density reduces. and this class additive is well-known in plastic industry. and they can be all kinds, usually being summed up as two series: CBA and physical blowing agent. it also can be used in combination. and this content can find in numerous technical writing case studies. and the amount that density reduces has significant variation with the amount of blowing agent and use. in general, " foam " is intended to expression, under same temperature and pressure condition, the density of this material be reduced to be lower than its initial value (reactive blowing agent) 20% or be lower than this value 10% and even be lower than the 5%. preferred of this value, expanding material is plastics.
The plate core that content obtains according to the present invention is for being clipped between the two-layer non-expansive material, and non-expansive material can be plastics, timber and/or metal.Preferably, two top layers are unexpansive plastics or one, and another is metal steel for example for unexpansive plastics, aluminium, etc.The situation that two skins (epidermis) are made by plastics is especially preferred.
In the method according to the invention, all types of plastics all are suitable as composition material.Especially the material of Shi Heing is selected from the thermoplasticity kind.
Any thermoplastic polymer represented in term " thermoplasticity ", comprises thermoplastic elastomer (TPE), and composition thereof.Term " polymer " " both represented that copolymer also represented homopolymers (particularly binary or terpolymer).The example of this analog copolymer is random copolymer, shape block copolymer, other block copolymer and graft copolymer.
Thermoplastic polymer or copolymer that fusing point is lower than any kind of decomposition temperature all are fit to.Thermoplastic synthetic resin with at least 10 degrees centigrade of melt temperature distributions is especially suitable.This class examples of material comprises that its molecular weight demonstrates those of polydispersity.
Especially, halogen polymer, polyolefin, thermoplastic polyester, polyketone, polyamide and its copolymer can use.Also can use the mixture of polymer or copolymer, also can be polymeric material and inorganic, organic and/or natural stuffing, (but being not limited to) carbon for example, salt and other inorganic derivative, the mixture of natural fiber or polymer fiber.
The present invention is by following generation good result:
The material of making honeycomb is vinyl chloride-base polymer (PVC), and preferred skin also is;
Expanded material is polyurethane (PUR).
The selection honeycomb is PVC, and outer is that the structure that PUR produces demonstrates good fire resistance properties for PVC and expanded material also, if resin formula (compositions) be selection meticulously especially true.The PVC and the PUR prescription (according to NFP 92.507) that are categorized as M1 respectively bring forth good fruit.In fact the dividing plate of this class material of use of obtaining of the method according to this invention will also be classified as M1.
As for the PUR foam, based on PIC, polyalcohol, the anhydrous formulations of amine (by using catalyst) and the HFC by using blowing agent can produce good effect.In view of water is used in particular for this fact of heat energy to remove the heat release expansion reaction in the multiple composition, this prescription itself is exactly beat all.Particularly, contain MDI (methane biphenyl diisocyanate),
The anhydrous formulations of the halogenation polyalcohol of class and the HFC-365mfc (1,1,1,3,3-five butyl fluorides) by using blowing agent can produce good effect.
Above-mentioned PUR composition is preferably with regard to pure and mild isocyanate functional group and stoichiometry, and to avoid forming PIC, it can fully not bond on the most plastics.This class synthetic can and be preferably at room temperature and expands, and it can avoid the demand to baker.
As for the PVC sheet, it can be by flexibility, and semi-rigid or rigid PVC is made, preferred M1 grade.Preferably, it is based on rigid PVC.
According to preferred variant of the present invention, at least one skin (and preferred two skins) is the sheet according to known molecular orientation techniques double orientation. especially with regard to amorphous polymer and preferred PVC, generally obtain double orientation by biaxial stretch-formed the cooling then in the temperature range of PVC glass transition temperature (Tg) and Tg+30 ℃.
According to the present invention, honeycomb can only be placed on first skin, and the composition that will contain blowing agent afterwards injects honeycomb, and another skin is placed in all tops.Alternatively, plastic honeycomb at first is fixed on the skin (film/sheet), or alternatively honeycomb is fixed on two skins.This can be finished by any suitable mode according to the character of material.Decide according to concrete condition, can use adhesive.Alternatively, when honeycomb and film/sheet were same material (for example PVC) or compatible material, it can be fixing by welding.The technology of a particularly suitable is with disclosed laser welding technology among the application FR03.08843 of the application company name, and its content quotes in full in this application.Honeycomb and layer are plastics, and particularly PVC makes, and this is the significant advantage of present technique.
According to the preferred embodiments of the invention, each skin is at first put into former with honeycomb assembling and two assemblies with a determining deviation, and the composition that comprises blowing agent thus can expand and freely expand when expanding.It can allow thus to pay close attention to very much the composition, foam that is injected into the honeycomb bottom, because can self spread.Only having a honeycomb to be fixed under the outer field situation, by the top of described honeycomb and above provide free space between the skin, this is suitable for equally.But, because the less enforcement of this structure of mechanical performance.
" former " of above-mentioned indication should be understood to be in the manufacture process prepares the forcing press that the various unexpansive element with plate keeps together and allows foam to expand therein.Usually, forcing press comprises two divided portion (bottom and top), and its can be fixed (this former is called as fixedly former) maybe can be moved (this former is called as mobile former).
Usually, fixedly former is used for the discontinuous method of the plate of once production regular length (this length is equal to the length of former).In these class methods, composition to be foamed injected usually in advance be positioned at (it can provide and be with or without honeycomb) on the skin in former bottom.The top of this former is closed down in the above then, and it sets in advance another skin that supports or do not support honeycomb, and said composition expands in the unit of honeycomb then.Advantageously, in a kind of like this method, before closing former, between two parts, introduce sept so that the selection thickness of plate to be prepared to be set.When not only introducing sept around the edge but also in the centre at forcing press, these septs are also advantageously made by foam, and as preferred especially, this foam also is the foam of preparation honeycomb of the present invention.It should be noted that such former can have nonplanar wall, so it can prepare curve or arc finished product.If so, last slice and following sheet must correspondingly combine with upper strata or lower floor's wall of former.
As for the former with moving end-wall, it is particularly useful for continuity method.In fact, " moving " should be understood that to mean such a case, and promptly this wall should be with the form winding cylinder of endless belt and with identical speed rotation.In these class methods, usually, composition to be foamed is at first all injected the unit that is fixed in or places a honeycomb on the skin, and integral body is placed on the bottom of (moving) former then.Simultaneously, another skin (it can support or not support honeycomb) is fixed on another part (top) of former, also moves with same speed.The whole time of staying of the rotary speed of the length of former and cylinder control in former, it needs long enough so that desirable expansion to take place.In the method, the cylinder separation and the thickness of endless belt decision plate thus.
In the method with in discontinuous method, wherein by the thickness of sept limiting plate, can be designed to unworn plate is not directly contacted with the honeycomb of another layer, this is perhaps in order to allow foam expansion to surpass (crossing the top) honeycomb extra play of the foam that honeycomb strengthens (enter can't help).Also can design keriotheca in the method and all contact, can when finishing this method, contact with two unworn foams of filling between the frothy honeycomb with each skin of this structure.
No matter be according to continuous or discontinuous method of the present invention, fixed cellular and outer field step, can implement respectively, promptly, by the individuality different and/or in different positions and/or in different with the next step of this method. thus, from industrial point of view, produce according to plate of the present invention in order to comprise the composition of blowing agent by injection among former and expansion, prove that it may be favourable buying prefabricated external layer/honeycomb.
According to the present invention, can make composition foaming (expansion) by heating in baker, or only by mixing each component and reaction being taken place.Preferred aftermentioned method.Because this reaction is heat release, the temperature when it reacts in the composition increases and may reach a high temperature at certain point (for example 150 ℃).Surprisingly, as previously explained, it does not cause the distortion of honeycomb, may reduce the thermal conductivity of composition because expand.
No matter how this method designs, as preferably, by this composition of premixed at least 2 parts obtain will foaming composition, it only mixes before expansion.Particularly with regard to PUR, preferably at first mixing, is PIC and some blowing agents of possibility on the one hand, is polyalcohol on the other hand, amine and remaining blowing agent.These two parts are injected in the mixer to the former feed then.The amount of the mixture that uses will realize: after the foaming, reach the target density of foam, note the finished product thickness of plate and therefore with the volume that is filled.
Advantageously, all elements of plate all remain under the pressure in (foaming) process that expands, and the purpose of this behave is, especially, guarantee to bond well between each element of this structure and stablize its size.
Should be noted that, above mention, can be fixed on two skins on the honeycomb and so the composition of latter two honeycomb by wherein expand will be advantageously by foam-filled, and, as preferred especially, also will separate by the froth bed of not using (virgin) (no honeycomb).With regard to taking into account between mechanical strength and the weight, last this variant brings forth good fruit.
