Abstract
The invention discloses a steel-plastic co-extruded energy-saving profile full coated with hard PVC (polyvinyl chloride) and relates to the technical field of profiles. The profile comprises a hard PVC layer (1), a PVC foamed layer (2) and a cavity steel-liner (3). The PVC foamed layer (2) is arranged on the inner side of the hard PVC layer (1), the cavity steel-liner (3) is arranged on the inner side of the PVC foamed layer (2), and the hard PVC layer (1), the PVC foamed layer (2) and the cavity steel-liner (3) are engaged into a whole tightly. The profile is simple in structure and convenient to manufacture. According to the excellent heat-insulation performance of PVC foamed materials, the high strength of steel and the attractive appearance, the maintenance easiness and the weldability of the hard PVC, defects that common PVC plastic doors and windows are low in elasticity modulus and poor in wind load resistance, steel windows and aluminum-alloy windows are poor in sound insulation and the like, existing steel-plastic co-extruded door and window profiles are easy to be aged, poor in welding and prone to brittle rupture are overcome, and physical properties of doors and windows are improved remarkably.
Description
Technical field:
The present invention relates to section bar technical field, be specifically related to a kind of three-in-one plastic-steel (aluminium) energy saving composite material.
Background technology:
That current building doors and windows section bar mainly contains is wooden, aluminium alloys, PVC plastics and bridge-cut-off aluminum etc. are several.Timber window can enrich but aging ability in moulding, cold and hot flexible large, perishable after exposing to the sun and rain.Alumium alloy door and window have good weatherability and ageing resistance but heat-insulating sound-insulating weak effect, and plastic door-window has good heat-insulating sound-insulating and airtight of water tightness, not only anticorrosion but also insulation but have the low process of the intensity phenomenon of easily using inferior materials and turning out substandard goods.Bridge-cut-off aluminum has had compared with its tool higher-strength and heat insulation performance of much progress, but price and cost of manufacture are all higher, and the uneven difficult quality guarantee of its heat insulating strip.It combines the intensity of steel (aluminium) and the advantages such as heat-insulating sound-insulating of PVC foamed plastic to have occurred again in recent years a kind of steel (aluminium) plastic co-extrusion section bar, but due to the restriction of formula with production technology, there is serious embrittlement problem in the micro-foaming layer of surface plastics, and easily deliquescing is aging under sun direct projection or high-temperature condition.
Summary of the invention:
The object of this invention is to provide the full steel-plastics covered co-extrusion of hard PVC energy-saving profile, it can be simple in structure, easily manufactured, have good sound-insulating and heat-insulating heat-insulating property, and wind resistance anti-pressure ability is high, handsome in appearance, easily safeguards and can weld.
In order to solve the existing problem of background technology, the present invention is by the following technical solutions: it comprises hard PVC layer 1, PVC foaming layer 2, die cavity steel lining 3, hard PVC layer 1 inside is provided with PVC foaming layer 2, PVC foaming layer 2 inside are provided with die cavity steel lining 3, and hard PVC layer 1, PVC foaming layer 2 and the tight interlock of die cavity steel lining 3 three are integrated.
The skin of described door-window section bar is that hard PVC layer 1 is entirely coated.
Described die cavity steel lining 3 for diameter be the steel lining of 0.8 millimeter of above roll forming.
Production technology of the present invention:
A, the steel lining of roll forming heats after being coated with affinity agent in advance, then by conveyer, is sent into the co-extrusion die head of preheating;
B, PVC foamed material are clamp-oned the co-extrusion die head of preheating through twin-screw foam extrusion machine, through independent runner, be attached to steel lining around and combine closely;
C, hard PVC compound are extruded the co-extrusion die head that enters preheating through double screw extruder, be attached to foaming layer form one deck PVC topping outward through independent runner bag;
D, trilaminate material are extruded through a co-extrusion die head, then through shaper sizing die cavity steel lining, hard PVC, the PVC three-layer co-extruded section bar that foams.
The present invention has following beneficial effect: it can be simple in structure, easily manufactured, utilized the good heat preservation and insulation of PVC foam material, the high strength of steel and hard PVC attractive in appearance, the advantages such as easy maintenance and solderability, have overcome the low resisting wind press capacity of common PVC plastic door-window modulus of elasticity poor, the shortcomings such as steel sash aluminum window heat insulation beat, overcome again the poor easily crisp defect of the easy aging welding of existing steel-plastic coextrusion door-window section bar, obviously improved the physical property of door and window.

The skin of described door-window section bar is that hard PVC layer 1 is entirely coated.
Described die cavity steel lining 3 for diameter be the steel lining of 0.8 millimeter of above roll forming.
The production technology of this specific embodiment:
A, the steel lining of roll forming heats after being coated with affinity agent in advance, then by conveyer, is sent into the co-extrusion die head of preheating;
B, PVC foamed material are clamp-oned the co-extrusion die head of preheating through twin-screw foam extrusion machine, through independent runner, be attached to steel lining around and combine closely;
C, hard PVC compound are extruded the co-extrusion die head that enters preheating through double screw extruder, be attached to foaming layer form one deck PVC topping outward through independent runner bag;
D, trilaminate material are extruded through a co-extrusion die head, then through shaper sizing die cavity steel lining, hard PVC, the PVC three-layer co-extruded section bar that foams.
This specific embodiment has following beneficial effect: it can be simple in structure, easily manufactured, utilized the good heat preservation and insulation of PVC foam material, the high strength of steel and hard PVC attractive in appearance, the advantages such as easy maintenance and solderability, have overcome the low resisting wind press capacity of common PVC plastic door-window modulus of elasticity poor, the shortcomings such as steel sash aluminum window heat insulation beat, overcome again the poor easily crisp defect of the easy aging welding of existing steel-plastic coextrusion door-window section bar, obviously improved the physical property of door and window.
