Aluminum coated plastic heat broken bridge solid door and window profile and cold aluminum coating process thereof

Abstract

The invention relates to an aluminum coated plastic heat broken bridge solid door and window profile. The aluminum coated plastic heat broken bridge solid door and window profile comprises aluminum alloy and a plastic profile, wherein the aluminum alloy is adhered to the surface of the decorative surface of the plastic profile and tightly attached to the plastic profile; the plastic profile formsa heat broken bridge between the aluminum alloy; the plastic profile is a recycled composite plastic solid profile, inside which a plurality of bubbles are distributed. The aluminum coated plastic heat broken bridge solid door and window profile integrates the advantages of solid wood, PVC (polyvinyl chloride) and broken bridge aluminum door and window profiles and overcomes the shortcomings of traditional door and window profiles, and meanwhile is green, environmentally friendly capable of preserving heat and saving energy; besides, the aluminum coated plastic heat broken bridge solid door and window profile is high in overall strength, retards the ageing and deformation progress, endows shaped windows with colorful appearances and high color selectivity and prolongs the service life of doors and windows; matched with a cold aluminum coating process, the aluminum alloy and the plastic profile can be tightly combined.

Description

technical field [0001] The invention relates to the technical field of doors and windows, in particular to an aluminum-plastic-coated integral thermal break bridge solid door and window profile and its cold-clad aluminum process. Background technique [0002] Now the commonly used door and window profiles on the market: [0003] Solid wood windows: Since China's basic national policy focuses on protecting forest resources, there are basically no logs used to process windows. At present, solid wood in the Chinese market basically relies on imports, which are expensive. [0004] PVC is the mainstream civil window in Europe, and its product quality and thermal insulation performance can meet the performance requirements of civil windows. Due to the poor quality of PVC profiles in China, it cannot meet the performance requirements of processing high-quality windows, and it is basically in the production of low-end windows. [0005] Broken bridge aluminum was invented by Schüco ...

AI Technical Summary

Problems solved by technology

[0005] Broken bridge aluminum was invented by Schüco in Germany. In the European market, it is mainly used for doors and windows with large openings. It is rarely used in civil buildings. The main problem is that the broken bridge aluminum profile is a passive nylon and aluminum alloy composite structure. The expedient technology adopted is as follows: Reduce the high conductivity coefficient of aluminum alloy, but the conductivity coefficient of the profile itself is still very high, and the strength of nylon is lower than that of aluminum alloy, so the strength coefficient of the profile is greatly reduced, and the thermal expansion and contraction coefficients are not equal to the problem of service life It is also shortened accordingly, and effective heat insulation can only be formed when the nylon cavity of the broken bridge is larger than 20mm. At present, most of the nylon broken bridge cavities of domestic broken bridge aluminum alloys are less than 15mm

[0006] After the broken bridge aluminum alloy is made into windows, there are still insurmountable congenital defects. For example, the waterproof problem of the corners can only be solved with glue. At present, there is no qualified corner glue in China except German guard glue. The cold air in northern China seeps into the cavity and the broken bridge is useless

Due to the complex structure of the window, the processing and installation and maintenance of the window are very complicated.
