Description
Technical field
The present invention relates to a kind of wood plastic product, enhance wood plastic product in especially a kind of fiber.
Background technology
The common section structure of wood plastic product is square hole, circular hole, solid etc. at present, and there are the following problems：Conventional wood moulding system
The mechanical property of product compares the mechanical property of solid wood there are huge gap, and intensity and modulus differs greatly with solid wood, thus
Conventional wood plastic product is as structural member with being severely limited, and there are serious for the use in the fields such as furniture, outdoor plank road
Security risk；In addition, since conventional wood plastic product contains a large amount of resin base material, the heat resistance of product is excessively poor,
It is easy buckling deformation in applied at elevated temperature environment, dimensional stability has a serious defect, and the intensity of the general universal product is also
In 20MPa or so.
Invention content
Based on this, being provided it is an object of the invention to overcome in place of above-mentioned the deficiencies in the prior art enhances in a kind of fiber
Wood plastic product.
To achieve the above object, the technical solution used in the present invention is：A kind of fiber is interior to enhance wood plastic product, including this
Body and the clamping groove being set at left and right sides of the ontology, the ontology lower surface are equipped with multiple grooves, two neighboring groove
Between form support leg, fibre reinforced materials compatible with the body outer surface shape is distributed in the body interior.
The structure design of enhancing wood plastic product in fiber of the present invention, it is contemplated that single side uses, and can reduce use to the greatest extent
Material, while keeping intensity；Material materials part can reduce by 20~40%, using planar support, because product corner location is thin
Weakness or stress point, fibre reinforced materials are equipped with multiple " supporting racks ", in embedded support leg, can further increase plate surface
The integral strength of bearing capacity and product；Meanwhile resistance to deformation and anti-shrink ability also further strengthen.
Fibre reinforced materials is distributed to the surrounding edge portion of proximate matter by the design of fibre reinforced materials of the present invention as far as possible
Position, makes the anti-deforming force of product effectively be promoted, can obtain fibre reinforced materials the moment of inertia as big as possible, will be fine
Dimension reinforcing material is distributed to the surrounding edge position of proximate matter and saves fibre reinforced materials as possible as far as possible；Moreover, product and fibre
The contact area for tieing up reinforcing material is bigger, is more conducive to the release of the internal pressure in extrusion, is further able to improve product
Integral strength.
Preferably, the cross section of the groove is arch or trapezoidal.
The design of arcuate recess and trapezoidal groove increases the contact area between ontology and fibre reinforced materials, contact
Area is bigger, is more conducive to the release of the internal pressure in extrusion；Be conducive to the raising of interface bond strength, support leg is embedding
Enter into material, play the role of " rivet ", increase the combination of ontology and fibre reinforced materials, when product is by outer force effect
When, using faying face, slow down the transmission of power, while improving integral strength.
Preferably, the thickness of the fibre reinforced materials is more than 2mm.Present inventor passes through a large amount of exploration discoveries, on
The fibre reinforced materials for stating thickness is more preferable to the enhancing effect of wood plastic product.
Preferably, on the longitudinal section for enhancing wood plastic product in the fiber, the fibre reinforced materials area of section
Accounting is more than 25%.Present inventor passes through a large amount of exploration discoveries, and the fibre reinforced materials of above-mentioned section accounting can be into one
Step reduces fibre reinforced materials dosage, further saves on the basis of cost, more preferable to the enhancing effect of wood plastic product.
Preferably, the shortest distance of the fibre reinforced materials and described surface layer is not less than 2mm.
Closer to this surface layer, support enhancing effect is more apparent for the position of fibre reinforced materials；If but fiber reinforcement simultaneously
When material is too close to body upper surface or ontology lower surface, the wood plastic product surface be susceptible to marginal portion lack material,
It is recessed, has the problems such as white line.Present inventor has found by numerous studies, when the fibre reinforced materials and described body surface
When the shortest distance of layer is not less than 2mm, the ratio at the high position of possibility of wood plastic product exterior quality decline is caused to inhibit to exist
Low-level, as molded product entirety, it can be ensured that good decorative cover can realize good decorative appearance.
Preferably, the support leg lower surface is equipped with multiple dentation bound feets.The design of dentation bound feet, it can be ensured that material is pacified
Dress is secured.
Preferably, the fibre reinforced materials is fiber-reinforced polymeric resin；Wherein, the fluoropolymer resin be PBT,
At least one of PET, AS, ABS, PA, PVC, PE, PP；The fiber is glass fibre, carbon fiber, Kev drawing, basalt fibre
At least one of dimension, plant fiber, steel fibre.
It is highly preferred that the fluoropolymer resin is AS, the fiber is glass fibre or carbon fiber.
Compared with the existing technology, beneficial effects of the present invention are：
The structure design of enhancing wood plastic product, the fiber reinforcement knot of arcuate recess and trapezoidal groove in fiber of the present invention
Structure designs, it is contemplated that single side uses, and can reduce to the greatest extent with material, while keeping intensity；Material materials part can reduce by 20~
40%, using planar support, because product corner location is weak spot or stress point, fibre reinforced materials is equipped with multiple " supports
Frame " is embedded in support leg, can further increase the bearing capacity of plate surface and the integral strength of product；Meanwhile resistance to deformation and
Anti-shrink ability also further strengthens.
