Description
Technical field
It is a kind of production work of door and window composite steel-plastic sections the present invention relates to the processing method technical field of composite material
Skill and its production line.
Background technology
With the development of technology, to the performance requirement of building doors and windows also more and more higher, good building doors and windows must be same for user
When possess good anti-wind pressure, air-tightness, watertightness, heat insulation property, daylighting and sound insulation property, and use single one at present
Planting the door and window based on material can not fully meet above-mentioned requirements.Therefore, current aluminum alloy doors and windows be by using it is nonmetallic every
Between hot bar carries out disconnected heat to section bar to solve the problems, such as that material thermal conductivity is high, but the hot aluminum alloy doors and windows that break have two aluminium section bars
In small distance, it is impossible to more cut-off heat radiations, the thermal effect that breaks is not enough and relatively costly；PVC plastic door and window is then in door-window section bar
Install steel lining in cavity additional to improve the intensity and anti-wind pressure of section bar, be not to be fitted close due to steel lining and plastic material inwall,
The effect of increase intensity that can only be limited and anti-wind pressure, while PVC material easy weather stain out of doors.
A kind of manufacturing process of composite steel-plastic sections is disclosed in Chinese invention patent CN200810233281.X, it is described
Manufacturing process be specially：Steel profile and plastic material are first prepared respectively, then again both is prepared together, and it is prepared one
Rise idiographic flow be：--- gluing --- wearing bar --- pressurization is compound for fixed section bar.This manufacturing process has the following disadvantages：
1st, process is complicated, including slitting, clod wash prepare steel profile, and extrusion prepares plastic section bar, then fixed by steel profile, gluing,
Wear bar, the operation such as compound of pressurizeing and prepare composite steel-plastic sections, production process qualifying point is more, and production is unstable.
, after steel profile and plastic material composite surface gluing, composite surface viscosity is very big, by 6 meters of plastic section bars long through
Machine for stringing is needed between two steel profiles 6 meters of strokes long and a larger power output, and power output it is larger when, easily
Damage plastic material.
