Enough achieve the purpose that save material.And thermoplasticity core material (polypropylene PP, polyethylene terephtalate, polythene PE,
Polyamide PA or polyurethane PU material) because the characteristics such as big, good toughness of light weight, intensity are shown one's talent, more and more opened
Hair utilizes.Even if under some high-temperature work environments, it is also desirable to using thermoplasticity core material as material (such as the automobile being often exposed to the sun
Inside gadget etc.), but the mechanical property decaying of cellular thermoplastic battenboard at high temperature is obvious, and attenuation amplitude reaches 50% or more,
Under high temperature environment easily aging, damage, influence using, production, also cause security risk.Therefore it provides a kind of light weight, strong
Degree is big, good toughness, it is nontoxic, tasteless, recyclable and can cellular thermoplastic core plate resistant to high temperature become the urgent of this field
It needs.
Patent 201610513726.4 discloses a kind of using paper honeycomb core as the application of the battenboard of sandwich layer.The battenboard is adopted
With paper honeycomb core, and surface layer is the glass fibre felted terxture of polyurethane adhesive dipping, preparation method are as follows: by two glass mats
Tiling, the face-up placement that wherein glass mat is contacted with honeycomb paper core, to glass mat even application polyurethane adhesive.It should
Although the smell of method is better than wood-fiber board or hemp fibre board, but still can not meet automotive upholstery with other to odor requirements
The requirement of stringent product.
Patent 201621067499.9 discloses a kind of cellular board of PP sandwich layer, and the bending property of the product at high temperature declines
Subtract about 50%.Client is unable to satisfy to the mechanical property requirements under product high temperature.
Summary of the invention
Present invention aim to address the various defects of honeycomb board in the prior art, provide a kind of light weight, intensity it is big,
Good toughness, it is nontoxic, tasteless, recyclable and can cellular thermoplastic plate resistant to high temperature, in 80 DEG C of bending property retention
70% or more.Testing standard is GBT 1456-2005 sandwich structure bending property testing standard.
Above-mentioned purpose of the invention is achieved by the following technical programs:
A kind of high-temperature-resistant thermoplastic honeycomb board is provided, is combined by upper and lower deck panels and intermediary cellular core layer,
It is characterized in that, the honeycomb core plate has cellular unit, and the production raw material of honeycomb core plate includes basic material and high temperature resistant addition
The partial size of material, the high temperature resistant additive is R, and high temperature resistant additive partial size R (mm) and the ratio of cellular unit height H (mm) are
A=R/H, wherein 10-4≤A≤10-3；The high temperature resistant additive accounts for the mass percent W and cellular unit of the production raw material
Height H (mm) ratio be B=W/H, wherein 10-3≤B≤10-1。
Preferably, 10-4≤A≤5*10-4, 10-3≤B≤5*10-2。
Further, the high temperature resistant additive is talcum powder, calcium carbonate, mica, wollastonite, kaolin, diatomite etc.
One of or it is a variety of.Preferably talcum powder and calcium carbonate.
Further, the height H of the cellular unit is 5-30mm.
Further, the honeycomb core plate arranged adjacent one another is made of the cellular unit of hollow regular hexagonal prism.
Further, hot conditions are 80 DEG C.
Further, the high-temperature-resistant thermoplastic honeycomb board under the high temperature conditions, bending property retention 70% with
On.
Further, two-layer panel thickness is identical, and plate thickness 0.3mm-2mm, plate thickness is preferably 0.5-1mm.
Further, the basic material is thermoplastic material, one kind or several selected from PP, PET, PE, PA or PU material
The composite material of kind.
Further, the material of the panel is consistent with the basic material of the honeycomb core plate.
After honeycomb core plate is squeezed out by extruder serialization, hexagonal honeycomb core is shaped to by honeycomb core particular mold
Structure, then honeycomb core structures and upper and lower panel first heat in compound press, then cooling and shaping under a certain pressure,
Honeycomb core plate and upper and lower panel are bonded together, honeycomb board product is processed into.
Beneficial effects of the present invention:
The present invention is used in the honeycomb core plate production of high-temperature-resistant thermoplastic honeycomb board, and high temperature resistant additive is added, from
And reach cellular thermoplastic plate characteristic resistant to high temperature.Applicants have found that the height of cellular unit and the addition of additive
Measurer has exponential relationship；Additive too high levels, heat resistance increase, but since to account for total raw material specific gravity excessive for additive,
Lead to the toughness and intensity decline of product.Additive content is too low, and toughness is stronger, but heat-resisting ability is inadequate.Through
Cross Experimental comparison, it is found that 10-3≤B≤10-1It is more appropriate, 10-3≤B≤5*10-2When it is more preferable；On this basis, apply
There is also exponential relationships for the height and the partial size of additive that people has found cellular unit；The partial size of additive is excessive, influences the tough of plate
Property, intensity, heat-resisting ability are also weak；And if partial size is too small, the intensity and toughness of plate are also inadequate.A value range is 10-4≤A
≤10-3When have preferable effect, and A value meet 10-4≤A≤5*10-4When, plate properties reach most preferably, intensity and
Toughness with common product mean value difference with insignificance
