Compared with related technology, the application's has the beneficial effect that：
(1) extrusion die of the composite board of the coextrusion mold of the embodiment of the present invention, the composite board of the embodiment of the present invention,
The mental section for selecting open-type, does not use silent shape, has both ensured ash wall body plate fundamental strength, saved rolled steel dosage, simultaneously
Realize that the expanded material for being passed through molten creates condition for extrusion die.It is arranged in pultrusion extrusion die, foaming layer
Raw material can enter mental section by runner from mental section opening position, then pass through the first mold core hence into the first chamber
Then room is foamed in first chamber, form foaming layer, and such wood moulding, mental section and foaming layer form a compound entirety,
Enhance the thermal and insulating performance of composite plate.
Anchorage point is located to the position of embedded metal proximate matter when Wood plastic wall board carrys additionally weight, is fundamentally solved
Anchoring load-bearing problem of the Wood plastic wall board when hanging the weights such as air-conditioning, television set, by the portion of embedded metal thin plate in Wood plastic wall board
Position with house supporting frame carry out screw or bolt fastening link, fundamentally eliminate wood moulding as a whole wallboard intensity pacify
Full hidden danger；Wood-plastic material and the integral strength of metal structure are improved simultaneously, and has been disperseed because of metal material with wood moulding because of material
The stress that expands with heat and contract with cold that difference generates reduces flexible difference that two kinds of materials are generated by variation of ambient temperature to combined strength bination
Negative effect is conducive to after mental section and wood plastics composite the integral strength and mechanical strength of wallboard as a whole.
Since interior metal proximate matter effectively provides mechanical strength, mental section, foaming layer and wood moulding frame composite integrated
Change, thus the intensity requirement of wood moulding frame is reduced, foaming technique may be used in the material of wood moulding frame, to not only save
Wood moulding materials also substantially increase the heat insulating and sound insulating performance applied as ash wall body plate.
(2) first chamber of the composite board of the coextrusion mold of the embodiment of the present invention, wood moulding frame is provided with embedded or wears
Cross the protrusion of the pre-manufactured hole of mental section, such mental section forms embedded structure with wood moulding frame, allows wood moulding frame Cheng Jin
The compound realization integration of genotype material, " you are part of me, and I am part of you " further reduce two kinds of materials because variation of ambient temperature is produced
Negative effect of the raw flexible difference to combined strength bination, be more advantageous to mental section with after wood plastics composite wallboard as a whole it is whole
Body intensity and mechanical strength.

m2K is satisfied with the standard requirement of national novel wall heat preservation energy-saving 65%, higher by three than ordinary reinforced concrete wall thermal insulating effect
Times or more, it need not in addition increase installation insulating layer, there is good heat insulation effect.Also there is heat-insulated, sound insulation property simultaneously, it is simultaneous
The inside and outside Self-decorating performance of tool and the high feature of structural strength.Composite board flame retardant property is up to B1 grades.
(4) composite board of the coextrusion mold of the embodiment of the present invention, profiled metal composite board fully combine and have played steel
High intensity feature and wood moulding heat insulating and sound insulating, corrosion-resistant, good weatherability, do not crack, be indeformable, be easy to molding, incrustation
Property it is good the features such as, plate surface can carry out as needed the incrustations such as application, embossing, transfer, overlay film processing.
(5) composite board of the coextrusion mold of the embodiment of the present invention can be according to drawing directly from work when being used as ash wall body plate
Factory's blanking cutting, being transported to building site can be assembled directly such as building blocks, which can be pressed as needed
The various decorations processing such as flower, application, transfer, overlay film.The composite board is disposably solved from interior to outdoor wall,
Have the performances such as heat preservation, heat-insulated, sound insulation, indoor outer surface no longer needs other processing, the scenes of being greatly saved such as heat preservation to apply
Between working hour, onsite application caulking agent, face coat, nail, foaming fluid sealant etc. process are not needed, light house is obviously improved
While construction efficiency, live almost no pollution, almost without construction rubbish scene residual.Rapid construction, same ground base
The general same day can complete a whole set of villa under plinth and frame conditions.
(5) composite board of the coextrusion mold of the embodiment of the present invention, monolithic composite panel material section are designed as horizontal and vertical
Multi-chamber structure, multi-chamber structure are obviously improved heat insulating and sound insulating performance, and the only composite metal profile in a wherein chamber,
Can be solved the problems, such as in this way with relatively small number of mental section dosage Wood plastic wall board carry additionally weight and with the anchoring of load-carrying members.

Difference is：There are one the first mold core 34 and two the second mold cores 32 for setting in extrusion die 3, using in Figure 16
Shown in mental section 2,.
As shown in figure 16, the composite board setting produced is parallel in the first separation together of 1 plane of wood moulding frame
Muscle 11 with perpendicular to 1 plane of wood moulding frame together with second separate in muscle 12, first separate in muscle 11 and second separate in muscle 12
Wood moulding frame 1 is separated into one first and separates chamber and two second separation chambers, the wall surface of the first separation chamber is bonded with
Mental section 2, and foaming layer is filled and is bonded with, two second separation chambers are vacant.In the mental section 2 and Fig. 1 of Figure 16
Position of the mental section 2 in composite board it is different, the web of mental section 2 and the outer layer of composite board in Figure 16 (lean on
The inner wall on nearly composite board surface) mutually it is bonded.
Although disclosed herein embodiment it is as above, the content is only to facilitate understanding the present invention and adopting
Embodiment is not limited to the present invention.Any those skilled in the art to which this invention pertains are not departing from this
Under the premise of the disclosed spirit and scope of invention, any modification and change can be made in the implementing form and in details,
But the scope of patent protection of the present invention, still should be subject to the scope of the claims as defined in the appended claims.
