Description
Technical field
The invention belongs to geotechnical grid technical fields, more particularly to a kind of HDPE composite for geotechnical grid.
Background technique
High density polyethylene (HDPE) (High Density Polyethylene, referred to as " HDPE "), be a kind of crystallinity it is high,
Nonpolar thermoplastic resin.The milky appearance of ortho states HDPE, in meagre section in a degree of translucent.PE tool
There is the characteristic of excellent resistance to most of lives and chemicals for industrial use.Some kinds of chemicals can generate chemical attack, such as
Corrosive oxidation agent (concentrated nitric acid), aromatic hydrocarbon (dimethylbenzene) and halogenated hydrocarbon (carbon tetrachloride).The polymer is non-hygroscopic and has
Steam-preventing, can be used for packaging applicationss.HDPE has good electrical property, especially dielectric strength high, makes it very
Suitable for wire and cable.In to high molecular weight grades have fabulous impact resistance, room temperature even under -40F low temperature
So.
Using geotechnical grid made of HDPE sheet material, due to being limited by HDPE sheet material Material Strength itself, with
Engineering material is compared, and structural strength is lower,
Summary of the invention
The purpose of the present invention is to provide a kind of HDPE composite for geotechnical grid, by using HDPE lamella,
PE plastic layer and aluminum foil metal layer are mutually combined into a high-strength composite HDPE band, by using the compound HDPE band system of which
At geotechnical grid have high intensity, toughness and stability are good, solve existing geotechnical grid, due to by HDPE sheet material
The limitation of Material Strength itself, compared with engineering material, the problems such as structural strength is lower.
In order to solve the above technical problems, the present invention is achieved by the following technical solutions:
The present invention is a kind of HDPE composite for geotechnical grid, including base, cladding layer and HDPE lamella are described
Base is I-shaped PE plastics, and compound one layer of cladding layer is distinguished in the base two sides；Wherein, the cladding layer is one layer of aluminium foil
Layer；The outer surface of the cladding layer and HDPE lamella are compound.
Further, the base with a thickness of 0.5mm-1.5mm, the cladding layer is compounded in base by adhesive
On two sides.
Further, the range with a thickness of 0.05-0.1mm of the cladding layer.
Further, the range with a thickness of 0.5-2mm of the HDPE lamella；The HDPE lamella is by adhesive and melts
Coating is compound.
Further, the cladding layer is compounded in base by adhesive, and the HDPE lamella is compounded on cladding layer
Afterwards, by will be combined under cladding melting layer and HDPE lamella and base's high temperature.Cladding layer is compounded in base by adhesive,
The HDPE lamella is again melted base and HDPE lamella by the high temperature for generating cladding layer fusing after being compounded on cladding layer
In conjunction with.
Further, after combining under the cladding melting layer and HDPE lamella and base's high temperature, then pass through mechanical press
Compression moulding.Suppressed by mechanical press with guarantee it is integrally-built uniformly, be consistent the thickness of structure and dynamics.
The invention has the following advantages:
The present invention is mutually combined into a high-strength composite HDPE by using HDPE lamella, PE plastic layer and aluminum foil metal layer
Band has high intensity with manufactured geotechnical grid by using the compound HDPE of which, and toughness and stability are good, using direct
After pasting positioning, the compound of HDPE lamella and PE plastic layer is carried out by heating and melting aluminum foil metal layer, finally passes through machine again
Tool pressure compression moulding, an integrally-built strength and stability of enhancing.
Certainly, it implements any of the products of the present invention and does not necessarily require achieving all the advantages described above at the same time.
