The method of the present invention is described in further detail below with reference to embodiment.It should be strongly noted that of the invention
Protection scope should include but is not limited to technology contents disclosed in the present embodiment.
The production method of the natural stone composite board of plasticity processing of the present invention, the specific steps are as follows:
1) lithotome surface layer thin plate 1, the bonding preparation of the plane composite material plate of three-decker: is passed through into modified epoxy
Resin 2 is bonded on 3 surface of plastic material base；

Further, above-mentioned modified epoxy is nitrile rubber or polyacrylate.
Further, above-mentioned transparent epoxy resin is polyester resin.
Further, when above-mentioned punch forming is plane curved surface, slot segmentation is in stone material surface layer along perpendicular to arcwall face
Continuously cut parallel slot in the direction of expansion.
Further, when above-mentioned punch forming is abnormal curved surface, slot segmentation is the grid groove in stone material surface layer.
Further, above-mentioned plastic material base is aluminium sheet, copper sheet or acrylic board.
It is specifically described with reference to the accompanying drawing, the invention reside in using lithotome plate as surface layer, with ductility
Modified epoxy be adhesive layer, with mechanical plastic material (such as iron, copper, aluminium perhaps other alloy materials) or thermoplastic
Property material (such as acrylic, TPV, PE) plate be base.It is bonded the plane composite material of three-decker.And it is compound herein
The slot of the stone material surface layer cutting certain depth of material, keeps stone material surface layer holding pattern unity and coherence in writing continuous, but the plate of stress segmentation.
Make it possible plastic processing.Three steps of preparation process point:
The first step, the preparation of composite material:
As shown in Fig. 1: the bonding preparation of the plane composite material of three-decker: this modified epoxy is different from current
On the market for bonding brittle epoxy resin after the solidification of stone material, but there is elasticity and drawability, such as nitrile rubber or poly-
Acrylate etc. makes composite material in deformation, plays plastic deformation of the resin of adhesive effect with base's phase-contact surface with base
And it stretches, compress, but still maintain indeformable with stone material contact surface.And after the compression of ordinary epoxy resin Tensile, such as stone material
As fragmentation so that stone material layer and base material are detached from.
Step 2: composite material pre-processes:
In the stone material surface layer of the synthetic material prepared, certain thickness internal cutting slot segmentation makes surface layer form whole texture
Continuously, but the entirety locally isolated of stress.Product according to final molding is that plane curved surface or abnormal curved surface are divided into two kinds and cut
Cut mode: if it is plane curved surface, then in stone material surface layer along perpendicular to arcwall face expansion direction continuously cut in parallel, one
The slot of fixed width degree；If it is abnormal curved surface, then the grid groove of one fixed width is cut in stone material surface layer, and mesh segmentation slot can be
Arbitrary graphic pattern, however it is not limited to co-ordination.Make composite plate in punching course and stress after molding produces local stone material surface layer
Raw tensile strength and bending strength is lower than the yield limit of stone material, thus embrittlement or crushing during avoiding.And make corresponding surface
The peel strength of stone material-resin is less than its bonding force in product, and stone material and base is avoided to be detached from.
The spacing of slot segmentation and the Computing Principle of width: to reach the texture globality of the stone material surface layer after punching press most
It is good, the width of slot segmentation should be reduced as far as possible in the case where meeting above-mentioned stress condition, and increase the spacing of slot segmentation.
1, slot segmentation minimum widith calculate: slot segmentation separating large region be small area region stress while,
The surface area of seam also acts as the effect for allowing redundancy to deform, and as shown in Fig. 2, i.e., when stretching, the surface area of composite material increases
Add (such as extrados)；When compression, surface area reduces (such as intrados).Although the modified epoxy as adhesive is with base
The stretchable compressive deformation of plastic material changes area, but the stone material on surface layer does not have plastoelastic feature, and surface area is immutable.By
The difference of product-forming, each position in the design of the stretching die influence and continuous curve surface different with Sheet Metal Forming Technology, on direction
Radius of curvature variation, surface area stretching/compressing is than different.Enough slot segmentations are reserved in corresponding site according to process characteristic
Width makes total surface area of the resin after extension (compression) in the position slot add the sum of stone material total surface area equal to Pressing Deformation
The total surface area of base afterwards.
2, the maximum distance computation (density of slot segmentation in specified region) of slot segmentation: for any stone material surface selected
Raw material used by layer, the yield limit value through its bending strength and tensile strength known to actual sample test.To one at
The complete continuous curve surface of type does region segmentation according to local radius of curvature, by calculating stretching suffered by the stone material surface layer made in region
Intensity and bending strength are less than its yield limit.And reduce the density of slot segmentation as far as possible to obtain optimal texture continuity effect
Fruit.
With the outer spherical cambered surface (abnormal curved surface) for using stamping die that a radius of curvature is made as R to BxD rectangular region
For (attached drawing 5): when composite plate does Pressing Deformation, mold outer layer (cavity plate 5) presses F for stone material surface layer, thus
On the point of mold and face layer contacts, the power F1 for being tangential to spherical radius R is generated by frictional force, this contact point is rectangular in BxD
J, M in four angle point JKLM(sectional views in shape region).And mold internal layer (punch-pin 6) for base supporting point in the region BxD
Central point C(base and mold internal layer-radius be r spherical surface point of contact).This power F1 is equivalent to through resolution of vectors to stone material surface
Layer produces horizontally pulling force；Vertically to generation pressure,
And an equivalence is generated in the reversed removing pulling force F ' of F to resin and stone material binding site.When this pulling forceJ-M is acted on to cut
Face is more than the ultimate tensile strength (generally 15Mpa) of stone material, and stone material is pulled off；OrPressure is more than stone for C point torque
When bend yield strength noted (according to U.S.'s ASTM-C880 standard, being typically in the range of 400-1600psi, i.e. 2.8-10.3Mpa) of material,
Stone material surface layer can fracture in C point and generate comminuted damage；Or concentrate on the removing pulling force F ' of C point, intensity be greater than resin with
The bonding force of stone material, then surface layer and base are separated.
Above-mentioned solution is that shown part bXd small cube is divided into the region stone material surface layer BxD.(this is vertical vertical
Crosscutting secant simply to illustrate that embody a kind of scheme, in fact, slot segmentation can be arbitrary graphic pattern, however it is not limited to co-ordination.)
Attached drawing 3,4.The contact point of cutting in this way, cavity plate and surface layer is on the angle point of each bXd small cube, to make pressure F
It is uniformly distributed on the angle point of each bXd small cube, and punch-pin is made equally to take a walk in each bXd the supporting point of base
The central point of small cube.When pressure F is constant, the stress of composite material has obtained very because being dispensed on each small cube
Big improvement.Force analysis is as shown in Fig. 6:
Theoretically, in a given region BxD, the value of b, d are smaller, i.e. cutting groove density is bigger, and stress condition is got over
It is good.But density is bigger, the texture continuity of lithotome destroys bigger.When b, d value calculate stress meet stone material stretching and
When being bent yield limit, b, d value should be made to maximize.
After the pretreatment of the composite material of second step, this material is stamped/hot bending machine-shaping and to obtain curved surface vertical
The finished product of body.
Step 3: the repairing of finished product:
Using it is transparent (conventionally used for repairing stone material hole, hole, split line etc. solidification after in brittle) epoxy resin is (in industry
Referred to as polyester resin) joint filling, fill and lead up cutting groove again concordant with stone material surface layer, and polish to be formed completely through normal polishing program
Surface decoration layer.Because the region each fritter bxd is remained unchanged in the relative position of BxD, the continuity of stone texture
It is maintained.It is influenced by eye-observation angle, the surface after filling and leading up seems still to be complete whole, the aesthetic feeling of lithotome
It remains unchanged.Certainly, in order to obtain special decorative effect, cutting groove can not do joint filling processing.Obtained is exactly special
Columnar arrangement (abnormal curved surface) or (plane curved surface) arranged in parallel not only part, but also continuous curved surface and texture.
The present invention is using modified epoxy bonding lithotome surface layer thin plate and plastic material base, by pre-segmentation slot
Working process can be used plane composite material plate and stretch die stamping and plastic processing, realizes plane curved surface with planar materials
With the product of abnormal curved surface.Than two kinds of curved surface processing methods of aforementioned conventional, the use of material is saved, reduces material cost,
It is particularly evident in the luxurious grade stone material of high value；The pollution in material loss and process is also reduced, and makes product can be with
Large-scale batch production greatly improves labor productivity.And since lightweight manufactures, improve the applicable model of product
It encloses, and greatly reduces logistics cost and product breakage rate.
The foregoing is merely presently preferred embodiments of the present invention, all equivalent changes done according to scope of the present invention patent with
Modification, is all covered by the present invention.
