Description
Technical field
The present invention relates to a kind of plastic-steel section bar and preparation method are and in particular to a kind of new co-extrusion plastic-steel section bar composite
And preparation method thereof.
Background technology
Plastic-steel section bar abbreviation plastic-steel, main chemical compositions are pvc, are therefore also pvc section bar.It is widely used
A kind of new construction material, this material property is excellent, easy to process, of many uses, due to its physical property such as rigidity, bullet
Property, corrosion-resistant, ageing resistace is excellent, and being typically used as is the good substitute of the non-ferrous metals such as copper, zinc, aluminium.In building construction
It is mainly used in push-and-pull, the application of horizontally-opening windows and doors, guardrail, tubing and ceiling material.Plastic-steel section bar is to be main with pvc resin
Raw material, adds a certain proportion of stabilizer, colouring agent, filler, ultra-violet absorber etc., extruded institute forming material., plastic-steel
Why section bar can large-area be promoted is suitable for, and progressively replaces wooden and aluminium door and window, and its unique advantage is inseparable
's.Plastic-steel door and window has a following advantage than aluminium and wooden doors and windows:
1st, low price, the price of plastics is far below the aluminium with equality strength and life-span, due to being substantially increased of metal price
This advantage is more obvious.
2nd, rich color: being suitable for many good looks of increasing of building of chromatic plastic-steel section bar.Used wooden doors and windows in the past,
Perfect harmony with architectural appearance in order to reach door and window, how in door and window surface spray paint, ultraviolet easily aging stripping met by paint
Fall, have more than is needed several years just changed beyond recognition, very inharmonious with the life-span of building.Invented colored aluminium door and window later, but price
Costliness, ordinary consumer holds dares not accept.Plastic door-window solve this problem using perfection, pasted color-membrane section bar even can
To make the wood grain effect mixed the spurious with the genuine.
3rd, durable in use: to add enhanced type steel in section bar die cavity, so that the intensity of section bar is greatly improved, have anti-
Shake, weatherproof effect.In addition the multi-cavity structure of section bar, individual row water cavity, makes water cannot be introduced into enhanced type steel chamber, it is to avoid shaped steel is rotten
Erosion, the service life of door and window is improved.The addition of uvioresistant composition also makes the weather resisteant of plastic-steel section bar be improved, even if
The very strong torrid areas of ultraviolet also can be safe to use.
4th, good heat insulating: research shows, room summer of same type uses the room indoor temperature of plastic-steel door and window relatively
Aluminium door and window room averagely low 5-7 DEG C, winter different regions then to be exceeded 8-15 DEG C.
Widely using with plastic-steel section bar, some shortcomings also come out therewith, in a large number discarded plastic-steel section bar or life
Produce underproof plastic-steel section bar recycle improper easily cause white pollution, affect environment.
