Description

Three-layer common squeezing plastic-aluminum composite sectional bar
Invention field:
The present invention relates to a kind of composite material of making by metallic material and macromolecular material.
Background technique:
Patent CN200510007264.0, patent CN00267020.8 disclose a kind of PVC plastic-aluminum co-extrusion section bar of being made with single PVC plastics by the aluminium alloy lining parcel, the shortcoming of above-mentioned section bar is that the surface layer plastic material needs ageing, and anti performance, crocking resistance, shock resistance, appearance property because the outer surface material of aluminium alloy lining needs different performances with core material.Inner layer material requires with aluminium alloy extrusions bonding firmly, and anti-shock-absorbing capacity is coordinated the contraction internal stress that produces because of linear expansion coeffcient between aluminium alloy lining and the hard macromolecular material of surface layer.Above-mentioned functions can't be finished with single macromolecular material.
Summary of the invention:
The objective of the invention is to give full play to the effect of core material and surface material, reduce cost, obtain the composite material of high performance-price ratio by use the core material and the surface material of different performance at the aluminium alloy lining outer surface.
The three-layer common squeezing plastic-aluminum composite sectional bar that the present invention proposes comprises the surface layer macromolecular material, sandwich layer macromolecular material and metal inner core, inner core is an aluminium alloy extrusions, aluminium alloy extrusions outer wrap sandwich layer macromolecular material, sandwich layer macromolecular material outer wrap surface layer macromolecular material.For increasing the adhesive strength of core material and aluminium alloy extrusions, in the sandwich layer macromolecular material, be mixed with binding agent or between inner core aluminium alloy extrusions and parcel sandwich layer macromolecular material gluing or inner core aluminium alloy extrusions outer surface establish boss or groove, increase the area of contact of aluminium alloy extrusions and sandwich layer macromolecular material, increase join strength.
When the inner core aluminium alloy extrusions was hollow profile, the sandwich layer macromolecular material was wrapped in the aluminium alloy extrusions outside, and the surface layer macromolecular material is wrapped in sandwich layer macromolecular material outside.The sandwich layer macromolecular material also can be wrapped in aluminium alloy extrusions part outer surface, and the surface layer macromolecular material is wrapped in sandwich layer macromolecular material outside, and the aluminium alloy extrusions of wrapping portion is externally not exposed.When the inner core aluminium alloy extrusions was the opening section bar, the sandwich layer macromolecular material was wrapped in the aluminium alloy section surface outside, open interior centreless floor height molecular material, and the surface layer macromolecular material is wrapped in sandwich layer macromolecular material outside, and the open interior aluminium alloy extrusions is externally exposed.Use amount for lightening core floor height molecular material reduces cost, and is porose in the sandwich layer macromolecular material.
Macromolecular material is PVC, PE, PC, PP, ASA, PMMA, mould wood, PPO (PPO), Noryl (MPPO), polyphenylene sulfide (PPS), modification polycarbonate (PC), polyether sulfone (PES), polyether-ether-ketone (PEEK), polyimide (PI), Polyetherimide (PEI), PAEK (PAEK), polyethersulfone ketone (PPESK), polyether-ketone (PPEK), liquid-crystalline polymer (LCP), polysulfones (PSF), usually, sandwich layer adopts with surface layer and adds different auxiliary agents, different fillers, the macromolecular material of heterogeneity.Surface material requires to have anti ageing property, weatherability, thermostability and antiultraviolet and good shock resistance function, and requirement has color, pattern, the decorative pattern of decorative effect on the surface layer macromolecular material.Core material requires with aluminium alloy extrusions good adhesive property is arranged, and has good compatibility with surface material, and has the internal stress that coordination produces because of linear expansion coeffcient is different because of aluminium alloy extrusions and surface material.Because the surface layer macromolecular material requires different with the sandwich layer macromolecular material, the sandwich layer macromolecular material adopts different macromolecular materials with the surface layer macromolecular material, the auxiliary agent and the filler that use are also inequality, as: the surface layer macromolecular material adopts ASA, and the sandwich layer macromolecular material adopts PVC or plastic-wood material.The surface layer macromolecular material adopts PPO, and the sandwich layer macromolecular material adopts Noryl.The surface layer macromolecular material adopts and adds the colored polycarbonate of fire retardant, antiageing agent and filler, and the sandwich layer macromolecular material adopts and adds the binding agent polycarbonate.
