The invention relates to the multilayer composite sheet of making as the matrix material resin with thermoplastic resins such as high density polyethylene (HDPE) and polypropylene that can replace using as building and the glued board used of industrial materials.
About composite plate, if research is by combining the technology made from other materials, Korea S's application for a patent for invention prospectus is for 90-16984 number about composite shuttering, it belongs to following composite plate technology, be that synthetic resin board combines with support plate, use as a plate, the section of synthetic resin board will have the waveform shape of Gu Hefeng, and is bonding as its material, will be mutually different two layers with synthetic resin.But this patented technology has the secondary operations difficulties such as one side, sawing and ailing that only can use plate, the shortcoming of complicate fabrication process.
In addition, the flat 8-42134 of Japanese kokai publication hei 5-117629 and Te Kai, French Patent (FRP) 2690221A3 are about applying face veneer, make the micro concavo-convex of face veneer keep uniform goods with the resin combination that contains inorganic pigment or reinforcing fiber filler, Japanese kokai publication sho 61-141511 relates to the three ply board that the bonding aluminium that is positioned at the top and bottom of plate, glassine paper (Glass paper) etc. form on the part of composite foamed (the Composite foam) of central core, but it also has the shortcoming of regeneration difficulty.
About composite plate, if the technology that research and utilization injection moulding press moulding mode is made, Japanese kokai publication hei 4-19935 is the manufacturing process about the wooden decorative plate, this method is included in bonding impregnation urea resin in wood powder and the cellulosic micropowder, dry then, neutralization, sneak in the thermoplastic resin, operation with the shaping of wooden decorative plates such as thin slice, and the step of reprocessing each wooden decorative plate, this step is: along the thickness direction cross section be additional decorative panel on the netted synthetic resin pallet, pressurization is then processed with predetermined shape.But, said products, owing to be in the hollow bulb of central part, so can only use the goods of certain specification, use the occasion of a part after cut-out, physical characteristic is lower, and the modulus of elasticity in static bending of density contrast is lower, therefore it has as improper for the supporting material of concentrated load, the shortcoming that production method is not easy.
In addition, Korea S's application for a patent for invention prospectus is for 96-443 number about using the template of regenerating resin, it is a regenerating resin of transferring gel state with tabular extraction, when rolling with design thickness, carry out the goods of cooling forming, but that it has is heavier, according to the kind of regenerating resin and form the physical characteristic of decision goods, the shortcoming that production method is not easy.
About composite plate, as in be formed centrally the multiple field technology of hollow form, can enumerate Korea S's application for a patent for invention prospectus 96-4300 number, it is the technology about the concrete-type mould plate, it relates to 5 layers of structural slab, it is a stacked netted fibrous material on the hollow centre layer of trellis, form with the bonding compound resin foaming layer of hot melting way thereon, but it has following shortcoming, be that arlt's strata hinders the combination between resin bed, physical characteristic is lower, the fine separation difficulty of netted dimension during regeneration, because of the center be local concentrated load of hollow form opposing and impact intensity a little less than.
About composite plate, so, can enumerate Japanese kokai publication hei 4-50900, United States Patent (USP) 4386983, Japanese kokai publication sho 58-98341, Japanese kokai publication hei 8-93217 as the technology of closing the mode that sandwich construction, central core foam.Japanese kokai publication hei 4-50900 is about the good polypropylene of hear resistance, resistance to impact, rigidity or polyolefinic industrial multiple-plate technology of polystyrene, it is characterized in that with the filamentary thermoplastic resin lamella of glass A that contains 10-45% (weight) and inorganic attritive powder, the density 0.4-1.11g/cm that contains 5-50% (weight)
3The glass reinforced resin complex composite wafer that forms as structure sheaf of thermoplastic resin foam thin slice base material layer B.But it has following shortcoming, because the density of central core is 0.84-0.85g/cm
3, global density also is 1.75-1.76g/cm
3Thereby its density is bigger, and is heavier, and impact strength is lower.
In addition, United States Patent (USP) 4386983 is about stacked leached glass fiber infiltration layer, and on the two sides of the central core that foams stacked top layer and the battenboard that forms, but it has the production method complexity of goods, uses the shortcoming of difficulty with thermoplastic resin as the matrix material resin.
The three-decker plate that Japanese kokai publication sho 58-98341 is to use Wood flour filled polypropylene compound resin, the central core foaming is formed, still, it has the lower shortcomings of physical characteristic such as the modulus of elasticity in static bending.
In addition, Japanese kokai publication hei 8-93217 uses glass fiber-reinforced PP compound resin layer at extexine, uses the three-decker plate of polyurethane foam layer at central core.In the case because be to constitute, so the regeneration difficulty, production process is discontinuous and complicated by material not of the same race.
Moreover, Korea S application for a patent for invention prospectus 96-4278 is the technology about concrete blinding, it is with the stacked netted fibrous material up and down at the central core that has foamed, and thereon with the bonding 5 layers of goods that structural slab is special sheet that contain the filamentary compound resin layer of glass and form of hot melting way, but, as being used for the method that arlt's strata is stacked, at first behind stacked fibrage on the central core that has foamed, must be in its outside with the bonding compound resin layer of hot melting way, therefore be difficult to make the foaming condition variation of central core, can not be lower than 0.6g/cm with central core density
3Mode make, thereby consequently the density of goods is higher.In addition, because the separation difficulty of lamina reticularis, so there is the shortcoming of regeneration difficulty, because the interface binding power of interlayer is lower, so have the shortcoming that is difficult to improve physical characteristic.
Korea S application for a patent for invention prospectus 96-3938 is the plastic plate about using as concrete blinding or build-in components, it is by making polypropylene carry out low-density foamedly forming base material layer, form glass fibre on base material layer, form the goods that the mode of highdensity intumescent coating forms simultaneously, smoothness and intensity have been improved thus, but there is the bigger shortcoming of bending strength linear thermal expansion lower, the matrix material resin under the high temperature in it.
Korea S application for a patent for invention prospectus 95-26675 is light weight laminated plate and the overlapping method thereof about being made of thermoplastic resin, it constitutes the stacked and sticking face that forces together of multi-layer thermoplastic resin flake, because weight is lighter, so can solve the problem that produced because of the durability of single layer structure weight low and sandwich construction in the past, it relates to the thin slice of light layer and foaming and molding or the thin slice that is installed with the thin slice in a plurality of holes or forms a plurality of projections in top and bottom and constitutes the intermediate layer thin slice be stacked between the levels thin slice that is made of thermoplasticity synthetic resin, utilizes the overlapping method of combination, utilize the overlapping method of welding, utilize the overlapping method of the bonding material of hot melting way, overlapping method that utilizes vibration welded etc. carries out stacked technology.But above-mentioned method exists impact strength and high temperature bend strength is lower, linear thermal expansion is bigger shortcoming.
The modulus of elasticity in static bending when common drawback of above-mentioned plastic plate is 30-60 ℃ is lower.In addition, the coefficient of linear thermal expansion major part is 1 * 10
-4/ K, this is higher, the environment temperature of temperature etc. changes occasion greatly in one day, can produce the problem that is caused by the expansion of plate or contraction.If increase the content of filler, just solve above-mentioned shortcoming to a certain extent, still, increase the content of filler more, density just increases more, thus can not solve the problem that causes by the weight of goods, and inconvenient problem with use.
The problems referred to above are that the intrinsic property of commercial thermal plastic high polymer causes, and therefore in the goods of making using such material, it is inevitable shortcoming.In contrast, glued board reaches 1 * 10 at the coefficient of linear thermal expansion of 0-50 ℃ of scope
-5/ K, this is very little, the modulus of elasticity in static bending is 25000-50000kg/cm
2, be high, it is little that the physical characteristic under the high temperature reduces amplitude, but it is in light weight, and its density is at 0.6-0.8g/cm
3Scope.Yet existing goods etc. be because can not simultaneously fully satisfy above-mentioned full terms, so the function of substituting for plywood fully.
Therefore, the goods of the three-decker plate that has foamed as matrix material resin, central core with the thermal plastic high polymer compound resin, lighter than existing product weight, even can further improve the hot bending elastic modelling quantity in the hot conditions below 60 ℃, it still has the higher modulus of elasticity in static bending and coefficient of linear thermal expansion is 10
-5Therefore/K, and enough little, even it is big to be necessary in the exploitation one day that temperature etc. changes, still can make convergent-divergent keep very little technology.
In addition, as the matrix material resin of synthetic resin plate of material and add CBA in widely used high density polyethylene (HDPE) and the polypropylene, crosslinked in not improving the matrix material resin and when mixing the processing of other approach of melt viscosity of function resin etc., be necessary to study send as an envoy to that its frothing percentage is improved to 50% or more, reinforcement can be made the interlayer adhesion of goods, no interformational sliding, goods that physical characteristic is very high.
Therefore, the object of the present invention is to provide the glued board that can replace to use as building and industrial materials application, make by synthetic resin, the thermoplastic polymer composite panel that replaces the three-decker glued board, the plate that is central core is that following resin combination is foamed, mixing, fusion, extrude and make, this resin combination comprises: be selected from high density polyethylene (HDPE), polypropylene, the copolymer of ethene and propylene, propylene monomer composition are the matrix material resin 74-99% (weight) of the copolymer that constitutes of propylene more than 70% and alpha-olefin, preferably more than the 84-99% (weight); Be selected from by more than one the hollow ball body in ceramic beads, glass beads and the Thermocurable macromolecule bead, perhaps be selected from more than one the needle-like filler in glass fibre and the wollastonite more than one 0-25% (weight), best 0.1-15% (weight); And the blowing agent 0.1-1% (weight) that is selected from the inorganic foaming agent that contains sodium bicarbonate and citric acid or azodicarbonamide (ADCA) organic foaming agent more than one; The plate of epidermal area carries out mixing, fusion, extrudes and make following resin combination, this resin combination comprises: be selected from the copolymer by high density polyethylene (HDPE), polypropylene, ethene and alpha-olefin, the propylene monomer composition is the matrix material resin 55-89% (weight) of the copolymer that constitutes of propylene more than 70% and alpha-olefin; Be selected from glass fibre and the wollastonite more than one needle-like filler 10-35% (weight) and be selected from ceramic beads, glass beads and the Thermocurable macromolecule bead more than one hollow ball body 1-15% (weight).
Preferably from epoxy resin, phenolic resins, use as above-mentioned thermosetting polymer bead as selecting the polyvinylidene chloride resin of base with acryloyl group, preferably with the polyvinylidene chloride of acryloyl group as base.
Therefore, the present invention is that the useful glued board that has improved the synthetic resin board shortcoming that replaces glued board in the past replaces material, as building and the glued board of industrial materials application and using the feature of composite plate of the present invention is described below so that can replace.
The first, profile is identical with glued board; The second, there are not grain pattern and hollow space on surface and inside, be uniformly, therefore carry out secondary operations such as sawing, ailing easily; The 3rd, density is 0.6-0.8g/cm
3, weight is lighter; The 4th, coefficient of linear thermal expansion is very little; The 5th, the modulus of elasticity in static bending of density contrast is 35000-50000kg/cm
2, this is very high; The 6th, the modulus of elasticity in static bending of high temperature is improved; The 7th, produce easily; The 8th, almost can supply with the price of glued board is cheap in the same manner.
The structure of goods, plate as three layers sandwich structures, constitute by central core and extexine, central core is the foaming layer that forms fine pores, extexine is made of microballon combination (Syntaotic) the foaming reinforced compoite resin layer of high-intensity reinforced compoite resin layer that is mixed with an amount of inorganic filler or content inorganic filling, and the matrix material resin of each layer is thermoplastic resins such as high density polyethylene (HDPE) or polypropylene.The density of central core is 0.2-0.6g/cm
3, the average diameter of pore is in 0.5mm.Inorganic filler as extexine is glass fibre, wollastonite etc., the preferably glass fibre of 10-30% (weight).In addition; so-called microballon combination foaming reinforced compoite resin layer is that the hollow ball body with above-mentioned inorganic filler etc. and proper proportion mixes and the compound resin layer of mixing formation; as the hollow ball body; it is ceramic beads, glass beads or thermosetting polymer hollow ball body etc., preferably its diameter at 0.1mm with interior, internal pressure strength 400kg/cm
2More than, the real density of filling 1-15% (weight) is at 0.75g/cm
3With interior ceramic beads, contain the compound resin layer of 1-30% (weight) glass fibre.
In the present invention,, in the extexine of high-intensity reinforced compoite resin layer, use microballon combination foaming technique, find following effect the foamed core layer and the inorganic filler mixing of three layers battenboards.
Effect 1):, can make weight saving though keep the high-intensity modulus of elasticity in static bending and bending strength.
The density of nearly all inorganic filler is all greater than 1.0g/cm
3, therefore and mixed with resin, forming strengthening material, the various physical characteristics of the modulus of elasticity in static bending and bending strength increase, but its density also together increases, and are unusual difficulties as the processing of the high strength goods of lightweight therefore.In contrast, in the occasion of using microballon combination foaming technique as in the present invention, foamed cell is present in the inside with the high resiliency hollow ball body of matrix good bond, during therefore inorganics filled foaming, lower phenomenon of frothing percentage and foamed gas do not take place transfer to the phenomenon that physical characteristic is reduced, though therefore keep the high-intensity modulus of elasticity in static bending and bending strength, but still can keep lighter weight.
Effect 2): physical characteristics such as the modulus of elasticity in static bending under 30-70 ℃ the high temperature, bending strength are improved.
Plastics rise with temperature, and flexibility increases, so high density polyethylene (HDPE) and polypropylene etc. have lower high-temperature physical property.Especially, the occasion with the mixing material of the high material of thermal conductivity factor and thermal capacity more increases the flexibility of matrix, thereby has lower high-temperature physics characteristic under uniform temp.Yet in the present invention; the cavity that forms in the inside of having mixed ceramic beads, glass beads or thermosetting polymer hollow ball body etc. with proper proportion has heat insulating function, thereby makes 30-70 ℃ the high temperature modulus of elasticity in static bending and the raising of bending strength physical characteristic down.
Effect 3) makes the tucking that when the slab sheet of multilayer is shaped, causes and the overlapping wavy unsettled multilayers such as shape in the interface remarkable stabilisation that flows externally by recurrent interface flowing instability.
The hollow ball body of the circulus of having added, utilization reduces the shear stress of fluidized bed in pipe, make the tucking that when the slab sheet of multilayer is shaped, causes by recurrent interface flowing instability, and unstable multilayer such as the overlapping wavy phenomenon in the interface stabilisation that flows externally.Its result has improved the outward appearance and the physical characteristic of goods.
Effect 4): because effect 3 result) can use the lower thermoplastic long fibre compound resin of viscosity as extexine, makes to extrude the multilayer die head, consequently improves the modulus of elasticity in static bending of goods and linear thermal expansion etc. significantly.
The modulus of elasticity in static bending of extexine is big more, and the modulus of elasticity in static bending of goods is also high more, therefore uses the filler of long fibre shape than used the reinforcement filler of ultimate fibre shape more effective in the past.The method of the filler of infiltration long fibre shape is very many in the matrix material resin, but most of complex procedures, so productivity ratio and economy are low.In the occasion of process than the goods of simple procedures, infiltration property is relatively poor, thereby the characteristic of goods reduces.Therefore, developed recently utilize the pultrusion method in the matrix material resin, infiltrate continuously fiber, will have the fibre cutting of long length and form plasticity long fibre compound resin, it is just widely-used.
But above-mentioned compound resin is according to the characteristics in the manufacturing process, the viscosity of matrix material resin must be lower, therefore makes the extrusion molding thin slice, and its processing is difficult, physical characteristic to improve effect also little, the slab sheet that utilizes extrusion die processing multilayer is difficulty very.Yet, in the present invention, the minute spherical body that on extexine, uses together, utilization reduces the effect of the shear stress of fluidized bed in pipe, make the tucking that when the slab sheet of multilayer is shaped, causes by recurrent interface flowing instability, and the overlapping wavy unstable multilayers such as shape in the interface stabilisation that flows externally, therefore use thermoplastic long fibre compound resin, can make to extrude the multilayer die head, its result improves the modulus of elasticity in static bending of goods and linear thermal expansion etc. significantly.
In the method for the composite plate of making sandwich construction, the synthetic resin fusion crimping method of utilizing press molding, the superposition method of utilizing the multimode head are arranged, utilize the forming process of the logical die head (Multimanifold die) of many material, carry out many sealings method of combination etc. after extruding from die head.In the present invention, use has the former of multilayer slab sheet two extruders and that flow the Die-head connecting sleeve method to make.Being described in detail as follows of manufacturing process.
Said products is such production, promptly, in an extruder of extruding as extrusion equipment of the compound resin of extexine and extrusion foaming layer, be melted the resin of extruding and regulate wedge through each Die-head connecting sleeve and distribution, from sprue adjusting wedge, with after flowing through the moving combinations of states of three laminar flows in the pipe, be sent in the T pattern head, through a branch manifold, (the lamination bonding method: the former of multilayer slab thin slice combined techniques before the die head) is produced to regulate the wedge mode by the sprue that is extruded into the multilayer tablet with a figuration width and thick worker.
The fusion thin slice of Sheng Chaning according to the method described above, dull and stereotyped and be shaped through the cooling of bonding levels.Two intervals that cooling is dull and stereotyped up and down are adjusted to identical with the final thickness of goods.The hybrid resin that has mixed acrylic resin and certain amount of foaming agent masterbatch is extruded by the foaming layer extruder, perhaps mix a certain amount of hollow ball body and extrude in said mixture, perhaps the compound resin of glass fibre and ceramic beads mixes with each filler with final required ratio and extrudes.To according to the method described above the formed article test piece specification of measuring usefulness according to each physical characteristic cut off, measure its bending strength and impact strength.
