Technical Field

The invention belongs to the technical field of aluminum profile structures, and particularly relates to a heat-insulating composite profile with good heat-insulating property, which is suitable for doors, windows, curtain walls and the like.

background

The long-strip-shaped heat insulation strip is used for producing heat insulation aluminum profiles and is used for improving the heat insulation performance of the aluminum profiles when doors and windows are manufactured. The heat insulating strip with low heat conducting coefficient can prevent cold air in winter from being conducted to indoor space and hot air in summer from being conducted to indoor space.

The long-strip-shaped heat insulation strips are extruded (penetrated) along the areas of the edges of the aluminum alloy profiles respectively to assemble the indoor aluminum profiles and the outdoor aluminum profiles together.

Insulation mats made of polymeric materials have not only good insulation properties but also high load capacity and are designed to be loaded with (outdoor and indoor) aluminium alloy profiles. The material most commonly used to make the insulating strips is Polyimide (PA) reinforced with glass fibers, but some other material, such as polyester fibers, is also used. Acrylonitrile-butadiene-styrene (ABS) terpolymers, polyethylene terephthalate (PET) or Noryl^TMAmorphous mixtures of (polyphenylene ether, polystyrene). The shape of the insulating strips may vary, in addition to the material: straight type, omega shape (see cross section), cavity type, complex type, etc.

The door and window structure made of aluminum profiles is exposed to the atmosphere (cold and hot). The high temperature (temperature difference between the indoor profile and the outdoor profile) causes the outdoor profile to expand more than the indoor profile, thereby making the profile susceptible to deformation (so-called bimetallic effect, which generally refers to the different thermal expansion characteristics of an element consisting of two metals, respectively, at a particular temperature, but in the present case it is said that the various parts of a metal are exposed to different temperature conditions). Due to the different expansion characteristics of the outdoor and indoor aluminum profiles forming the door and window, an arch is generated, thereby losing the air tightness and heat insulation effect of the door and window.
