Preferred embodiment
Below according to example shown in the drawings the present invention is described.
According to flooring material 3 of the present invention, be that the face side that is stacked in the wood powder resin composite materials 1 that is composited by wood powder and thermoplasticity synthetic resin to major general's surface decoration material 2 constitutes, the thickness of wood powder resin composite materials 1 is at least greater than 0.1mm.Herein with flooring material 3 of the present invention, roughly distinguish into following two kinds of pattern: Fig. 1 to Fig. 4, shown in Figure 9, with thickness at least greater than the wood powder resin composite materials 1 of 0.1mm as base material, the surface decoration material 2 that is made of natural veneer etc. at the substrate surface lamination constitutes the pattern of flooring material 3, extremely shown in Figure 8 with Fig. 5, at thickness at least greater than wood powder resin composite materials 1 surface of 0.1mm, the surface decoration material 2 that lamination is made of natural veneer etc. constitutes the pattern of flooring material 3 simultaneously as the back lining materials 4 of base material in the back laminate of bathvillite composite 1.
In any example all with bathvillite composite 1 as the main composition layer.The manufacturing process of the wood powder resin composite materials 1 of the main composition layer of flooring material 3 is the composite with wood powder and thermoplasticity synthetic resin among the present invention, with wood powder as filler, by thermoplasticity synthetic resin extrusion molding, because can progressive forming, the most handy extruding formation methods such as historical facts or anecdotes border production be shaped.
But, when wood powder is carried out thermoplasticity synthetic resin extrusion molding as filler, because of the particle size of employed wood meal has limited forming thickness, and size tens of microns powdery wood powder is approximately arranged also on the other hand, thus cost very high, be not suitable for the building materials purposes.Generally speaking, the general about 0.1mm of particle size is above favourable to cost.When using this wood powder, in order to manifest performance, it is essential comprising 1 wood powder in the thickness at least.Therefore, the thickness of wood powder resin composite materials 1 of the present invention is greater than 0.1mm at least, and the thickness of wood powder resin composite materials 1 can suppose to comprise at least the general general low cost more than 1, the wood powder of the about 0.1mm of particle diameter.There is 1 situation in Figure 10 (a) expression wood powder 1a at bed thickness direction A, and there is 3 situation in Figure 10 (b) expression wood powder 1a at bed thickness direction A.Size d represents the diameter of wood powder 1a among Figure 10, and dimension D is represented wood powder resin composite materials 1, and symbol 1b represents the thermoplasticity synthetic resin layer in addition.
Mix with thermoplasticity synthetic resin with as the wood powder of filler as above-mentioned, can improve the physical propertys such as intensity, case hardness, Young's modulus of thermoplasticity synthetic resin monomer.As a result, guaranteed the anti-caster sliding wear.The shortcoming of thermoplasticity synthetic resin is that coefficient of thermal expansion is big, but can improve the thermal expansion contraction that produces because of heat by adding wood powder.In addition, also because of adding the cementability that wood powder improves thermoplasticity synthetic resin and surface decoration material 2 or back lining materials 4.The promptly general now surface decoration material as flooring material is under moisture state, use aqueous adhesive to fit come bonding with hot pressing natural veneer, implement the removal of moisture simultaneously, at this time because of the moisture of bonding agent and wet type veneer is moved to wood materials, and remove moisture, so the explosion can prevent hot pressing time the and guarantee bonding force by surface evaporation.But thermoplasticity synthetic resin monomer or do not have absorptive filler and the complex of thermoplasticity synthetic resin can cause the explosion phenomenon when bonding, cause bonding bad phenomenon.
By the above as can be known, the wood powder resin composite materials more than the used thickness 0.1mm is very useful.
In order to realize above-mentioned performance, the wood powder amount in the wood powder resin composite materials 1 is more preferably greater than more than the 30wt%.In addition, be preferable below the viewpoint 70wt% by formability.In addition, in processing, for stable the manufacturing, preferably press from both sides across poisture-penetrability material layer 6 bonding between wood powder resin composite materials 1 and the surface decoration material 2.The flooring material 3 of this formation is as Fig. 2, Fig. 4, Fig. 7, shown in Figure 8.
But, wood powder resin composite materials 1 contains the epidermal area 1b ' that enriches resin because of shaping forms on the surface shown in Figure 11 (a), after epidermal area 1b ' removed with sand paper mill etc., the wood powder 1a shown in Figure 11 (b) was with exposing surface, so it is bonding to use known aqueous adhesive.
But the material that comprises thermoplasticity synthetic resin is in the sand paper mill of reality processing, and to produce exchange frequency too high because of sand paper blocks, and also produces in addition because of sand paper grinds inhomogeneous grade and causes problem in this production of cementability deviation., press from both sides between wood powder resin composite materials 1 and the surface decoration material 2 herein as above-mentioned,, under worn situation of removing epidermal area 1b ', can utilize aqueous adhesive bonding without sand paper by poisture-penetrability material layer 6 across the bonding structure of poisture-penetrability material layer 6.In addition, will remove the moisture of bonding agent and the wet type veneer that constitutes surface decoration material easily by poisture-penetrability material layer 6, simultaneously because poisture-penetrability material layer 6 makes adhesive strength stable.Promptly when the time by surface decoration material 2 cakings as the picture natural veneer, because of hot institute moisture evaporated is absorbed by poisture-penetrability material layer 6, by the moisture that disperses poisture-penetrability material layer 6 and surperficial exterior material 2 bonding planes, ornament materials 2 can not expand, explosion etc., makes the bonding possibility that becomes between surface decoration material 2 and the poisture-penetrability material layer 6.Therefore, known surface decoration material 2 need not modification such as device specification such as press.In addition, with respect to the situation that surface decoration material 2 directly is bonded in wood powder resin composite materials 1, by the adjustment of the interlaminar strength in the poisture-penetrability material layer 6, density and the impregnation effect of bonding agent, more can improve the adhesive property of surface decoration material 2, and, can make the check board that keeps these performances without detriment to case hardness or the dimensional stabilitys that characteristic produced such as flatness, humidity because of wood powder resin composite materials 1.In addition, surface decoration material 2 also can not break or problem such as change in size.
Herein, employed poisture-penetrability material layer 6 can utilize for example paper, nonwoven, wood powder etc., and these all are the obtainable materials of valency.In addition, the viewpoint that the solidification effect of the bonding agent of using from surface decoration material 2 laminations manifests preferably uses fibers systems such as paper or nonwoven to be used as poisture-penetrability material layer 6.In addition, from the bonding viewpoint of wood powder resin composite materials 1, preferably use paper, the nonwoven of the fiber system of hybrid resin fiber with poisture-penetrability material layer 6.Preferably use the resin fibre that is used as being included in poisture-penetrability material layer 6 with wood powder resin composite materials 1 identical resin again.In addition, in order to ensure the adhesive strength of wood powder resin composite materials 1 with surface decoration material 2 both sides, the following so-called dual structure of poisture-penetrability material layer 6 usefulness constitute also can: near wood powder resin composite materials 1 side, use comprises the material of resin fibre layer, near surface decoration material 2 sides, use and material that the bonding agent compatibility is high (aqueous adhesive, for example paper pulp etc.).Herein, in order to ensure sufficient adhesion strength, the resin fibre use level of injecting poisture-penetrability material layer 6 is more preferably greater than 40%.
Constitute the main layer wood powder resin composite materials 1 of flooring material 3 of the present invention, in above-mentioned any example, employed thermoplasticity synthetic resin can be selected to be fit to by the physical propertys such as rigidity after compound with wood powder, limits especially.But consider from the obtaining of material, cost, environment aspect, polyethylene, olefin-based resin such as polypropylene and other resins are compared, and are preferably.In addition, for the dispersion and rigidity that improve wood powder and thermoplasticity synthetic resin, though do not limit especially, preferably by adding sour sex change polyolefin or coming sex change by adding acid.Can illustrate acrylic acid, maleic acid etc. for sour sex change.Consider cost, performance etc., by adding maleic acid denatured resin or maleic acid, the sex change when dissolving mixing or extruding is preferable.Flooring material that will be made of this wood powder resin composite materials 1 and known flooring material compare, except improving above-mentioned anti-caster sliding wear etc., by also improving resistance to water with the compound of thermoplasticity synthetic resin.In addition, use the situation of natural veneer as surface decoration material 2, when being suppressed at floor greenhouse, air conditioner, fan heater etc. and using by wood powder resin composite materials 1, it is flexible that humidity changes the natural veneer that is caused, and the result can improve fracture-resistant.Similarly, also can improve Yin Wendu and humidity changes the warpage caused, breaks.Split in the tip that can improve slot part or chamfered section when in addition, constituting grooved or chamfering type on flooring material 3 surfaces.
Though the manufacture method of above-mentioned wood powder resin composite materials 1 does not limit especially, aforesaid extrusion molding preferably uses progressive forming.For example certain size is tabular by T type mold extrusion molding, adjusts certain thickness by the polishing rolling, utilizes cooling to make 1 progressive forming of wood powder resin composite materials.When carrying out above-mentioned extrusion molding in addition, for example carry out wood substrate by glued board or so-called MDF, during back lining materials 4 extrusion moldings of the base material that inanimate matter material constituted etc., the laminate of nonwoven, thin plate, sheet material etc. also can come lamination bonding by thermogenetic fusion.
, can use mixing in advance wood powder that forms and thermoplasticity synthetic resin during extruding herein, in addition, also wood powder and thermoplasticity synthetic resin directly can be dropped in the extruder and be shaped.Mixing in advance method can be enumerated following two kinds: thermoplasticity synthetic resin and wood powder etc. are cut off heating and are come dry wood powder and partly dissolve mixing method by high-speed stirred produced, and by malaxator thermoplasticity synthetic resin are dissolved the method etc. that mixing dry wood powder is done glomeration fully again.Though limit especially, adopt preferably that the wood powder drying carries out simultaneously the former.In addition, adopting the method that wood powder and thermoplasticity synthetic resin are directly dropped into extruder is preferably for equipment cost.
As Fig. 5, shown in Figure 6, wood powder resin composite materials 1 its thickness that is composited by wood powder and thermoplasticity synthetic resin is at least greater than 0.1mm, the surface decoration material 2 that constitutes by natural veneer etc. at its surperficial lamination, and lamination back lining materials 4 constitutes flooring material 3 overleaf.Or as Fig. 7, shown in Figure 8, wood powder resin composite materials 1 its thickness of the synthetic village of composite thermoplastic fat is at least greater than 0.1mm, the surface decoration material 2 that its clip surface comes lamination to be made of natural veneer etc. across poisture-penetrability material layer 6, and in the flooring material 3 that lamination back lining materials 4 constitutes overleaf, even use thin wood powder resin composite materials 1 also can constitute the certain flooring material of thickness 3 by lamination back lining materials 4.This flooring board material 3 has anti-caster sliding wear, fracture-resistant, dimensional stability, resistance to water and has certain thickness and can cheap constitute.The back lining materials 4 that this situation is used as base material limits especially, but the padded coaming of the synthetic resin (rubber system) that can select aptly to use the wood materials of glued board, MDF, flakeboard, OSB etc. or have resiliency according to purposes, synthetic resin expanded material, fiber based material (nonwoven etc.).Wherein, for instance, it is also passable to constitute base material that general flooring material 3 uses the wood materials 4a of above-mentioned glued board, MDF, flakeboard, OSB etc. to be used as back lining materials 4, above-mentioned wood materials because of obtain easily die also favourable to the cost aspect.In addition, carry out flooring material 3 directly during the construction of nail on the floor basal disc as the picture concrete flat slab, wait by the basal disc face that absorbs construction surface concavo-convex and to guarantee the simplification of constructing or the situation of the sound insulation in the collective residence, padded coaming 4b can be used to constitute base material as back lining materials 4.
Padded coaming 4b with resiliency is not particularly limited with regard to material, but considers weight, sound insulation value, walking sense, cost etc., and fiber is that padded coaming is relatively good.For fiber is padded coaming 4b, can illustrate the fabric of fiber crops, silk floss, monkey grass, synthetic fibers, proportion is not particularly limited, but 0.2～0.3g/cm
3Relatively good.In addition, wooden tie-plate material 4a is used to constitute the situation of base material as back lining materials 4, also can constitute saw shape groove overleaf, and at its back laminate padded coaming 4b with as the sound insulation purposes.In addition, the thickness of wood powder resin composite materials 1 also will be done suitable selection originally according to purposes, one-tenth.This formation for instance, the skin section of glued board that uses as the back lining materials 4 of base material etc. even shortcomings such as trickle slight crack or hole are arranged, also can be guaranteed anti-caster sliding wear, resistance to water, these performances of fracture-resistant.
Fig. 3, example shown in Figure 4 are represented, are made of wood powder resin composite materials 1 in the base material of flooring material 3, present the configuration example of concavo-convex concaveconvex shape portion 5 at the back side of wood powder resin composite materials 1.In this example, concaveconvex shape portion 5 by wood powder resin composite materials 1 back side, carry out flooring material 3 directly during the construction of nail on the floor basal disc as the picture concrete flat slab, have easily along the concavo-convex basal disc face of construction surface with improve advantage such as sound insulation value.In addition, according to the spring constant of this shape when using the resiliency material can improve simultaneously as the floor.The constructive method of concaveconvex shape portion 5 limits especially, but considers that the cutting swarf of padded coaming lamination reduces and the production efficiency aspect, is preferably in to heat when wood powder resin composite materials 1 is made to carry out concavo-convex shaping, rather than is shaped with methods such as cuttings.
In addition, in arbitrary example of the present invention, all enumerate as the example of surface decoration material 2 as natural veneer, though with the plate of veneer decorative pattern also can, from obtaining the viewpoint of nature woodiness touch, natural veneer is reasonable.
In addition, as Fig. 9 (a) (b) shown in, when constituting the base material of flooring material 3 with wood powder resin composite materials 1, with wood powder resin composite materials 1 as 2 layers up and down, from the surface decoration material 2 wood powder resin composite materials 1d of portion far away, its wood powder cooperates ratio, and is also more passable than the wood powder resin composite materials 1e of the portion height of close surface decoration material 2.When promptly utilizing wood materials such as natural veneer to constitute surface decoration material 2, because of the surface decoration material 2 on flooring material 3 surfaces is too big with the size changing rate difference of wood powder resin composite materials 1 part at flooring material 3 back sides, the possibility that warpage takes place is arranged probably during manufacturing.Herein, with wood powder resin composite materials 1 as 2 layers up and down, from the surface decoration material 2 wood powder resin composite materials 1d of portion far away, its wood powder cooperates ratio, than the wood powder resin composite materials 1e of the portion height of close surface decoration material 2, by this, can allow the buckling force of surface decoration material 2 parts of the wooden system of flooring material 3 face side, cooperate the buckling force of the high wood powder resin composite materials 1d of portion of ratio identical generally with the rear side wood powder, so can suppress all warpages of flooring material 3.
