Abstract

The invention provides a three-layer coextrusion aluminium-plastic composite profile, comprising a surface layer made of polymer material, a core layer made of polymer material and a metal internal core which is made of aluminium alloy profile; the exterior of the alumina is wrapped by the polymer material of the core layer; the exterior of the polymer material of the core layer is wrapped by the polymer material of the surface layer.

Description

Field of invention: [0001] The invention relates to a composite material made of metal material and polymer material. Background technique: [0002] Patent CN200510007264.0 and patent CN00267020.8 disclose a PVC-aluminum-plastic co-extrusion profile made of a single PVC plastic wrapped by an aluminum alloy lining. Different properties are required, and the surface layer plastic profiles require high anti-aging performance, friction resistance, impact resistance, and appearance performance. The inner layer material is required to be firmly bonded to the aluminum alloy profile, have anti-buffer performance, and coordinate the shrinkage internal stress between the aluminum alloy inner lining and the hard polymer material of the surface layer due to the linear expansion coefficient. The above functions cannot be accomplished with a single polymer material. Invention content: [0003] The purpose of the present invention is to use core materials and surface materials with dif...
