Abstract

The utility model belongs to the technical field of building materials, and particularly relates to an ultrathin bendable natural stone composite board. The stone composite board comprises a wax layer, a stone layer, an adhesive layer and a metal base plate layer which are arranged from the outside to the inside in sequence, wherein the wax layer is oily wax; the stone layer is marble or granite with the thickness of 1-1.5mm; the smallest bending radius of the stone composite board is 500-600mm; the adhesive layer is a polyurethane adhesive with the thickness of 0.15-0.2mm and the elongation percentage being larger than 120%; and the metal base plate layer is a 5052-type alloy aluminium plate with the thickness of 0.8-1mm. The ultrathin bendable natural stone composite board breaks through the traditional concept that the natural stone board can not be bent and deformed, and proves that the composite board combined by the stone layer, the adhesive layer and the metal base plate layer can have certain degree of bending and deformation without fracture when the thickness of the stone layer is less than 1.5mm, thus opening up a new path for manufacturing arc-shaped natural stone composite boards.

Ultrathin bendable natural stone composite board

Technical field

The utility model belongs to building material technical field, and particularly a kind of ultrathin bendable natural stone composite board can be used for the face of cylinder of building or the incrustation of metope curved surface.

Background technology

Outside the building facing and interior facing often need be decorated stone material plates such as various natural marbles, granite, wherein for the cylinder and the used stone material plate of curved surface metope of building, as shown in Figure 1, conventional method is directly to cut out arc stone material plate by desired radian on the stone material raw material, wherein shows arc stone material plate 11 and stone material raw material 22.The leftover pieces that this method produces are a lot, waste very much stone material, and minimum thickness of slab general requirements less than 35mm, then adding man-hour as thickness of slab greater than 35mm, and the stone material plate is easy to generate fracture.In order to save lithotome, people begin to adopt thinner stone material plate and make stone composite board with the metal sheet applying, and the thickness of stone material plate is reduced greatly.At present, for the plane stone composite board, the minimum thickness of stone material plate can reach 5mm, if thickness less than 5mm, therefore the insider it is generally acknowledged that stone material can rupture when bending, can not produce.

Below in conjunction with the drawings and specific embodiments technical solutions of the utility model are elaborated.

The specific embodiment

Fig. 2 is the schematic diagram of the not case of bending of the utility model embodiment, comprises stone material layer 1, metal substrate layer 2, glue-line 3 and wax layer 4.

Stone material layer 1 can adopt natural marble and granite, and it adopts special processing method to make the thickness of stone material layer is 1-1.5mm, and its surface that combines with glue-line is the surface through coarse processing, makes itself and glue-line form indenting bonding surface.

Metal substrate layer 2 requires to have medium hardness and static strength and corrosion resistance, can adopt the metal of medium work-hardened condition, is that 4-6 level, the trade mark are 5052 alloy aluminium sheet as hardness level, and its main component is for containing aluminium 96-97%, magnesium 2.2-2.8%.The resilience after bending of the too high then substrate of intensity is bigger, is unfavorable for setting, and intensity is crossed low then substrate the plastic strain folding line is easily taken place after bending, is unfavorable for keeping perfect curve also to cause the stone material fault rupture easily.When the stone material layer thickness was 1mm, the metal substrate layer thickness was 0.8mm, and when the stone material layer thickness was 1.5mm, the metal substrate layer thickness was 1mm.

Glue-line 3 adopts elongation per unit length greater than 120% bonding adhesive, and as polyurethane adhesive, it is the elongation per unit length height not only, and still has flexibility after curing, makes stone composite board in the end during bending forming, and glue-line can not ftracture.When gluing, adopt ad hoc approach, so that glue fully infiltrates the rough surface and the curing of stone material layer.Bondline thickness is 0.15-0.2mm, and the consumption of bonding adhesive is 0.5-1kg/ square metre, generally uses 0.7kg/ square metre.

Wax layer 4 covers the upper surface of stone material layer 1, none provisioning request of its thickness, and for the stone material laminar surface of polishing, the wax layer is thinner, and for unpolished stone surface, the wax layer is thicker.For adapting to the bending forming of stone material layer, adopt the oiliness wax in the industrial wax product.

Fig. 3 is the schematic diagram of the bending forming state of the utility model embodiment.

For the thick stone material layer of 1mm, stone composite board minimum bending radius R is 500mm, and for the thick stone material layer of 1.5mm, stone composite board minimum bending radius R is 600mm.In other words, for the thick stone material layer of 1mm, the radius of curvature R of stone composite board of the present utility model can change according to product requirement between infinitely great (dull and stereotyped state) at 500mm.Length (arc length) as for stone composite board is also decided according to product requirement.For example, be 1 meter cylinder for diameter, can adopt the stone material layer thickness is that two stone composite boards of 1mm surround cylinders, the length of every stone composite board (arc length) is about 1.57 meters (pi/2s), can certainly be with the stone composite board more than or three.

The utility model has been broken through the lithotome plate can not diastrophic traditional concept, proof stone material layer is combined the composite plate made from glue-line and metal substrate layer, when stone material layer thickness during less than 1.5mm, can have certain flexural deformation and can not rupture, thereby open up a new road for making the arc natural stone composite board. Because product of the present utility model has certain crooked free degree, can be according to the curved surface requirement of building cylinder or metope, the plate bending of the ultrathin natural stone material composite plate made is become desired shape, therefore compare with arc lithotome plate, greatly improved working (machining) efficiency and the waste that has reduced lithotome. In a word, adopt the utility model can reach the good result of saving natural resources, reduction product cost and weight, convenient making and construction.
