Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building doors and windows, and in particular to an inner plastic outer aluminum profile. BACKGROUND

[0002] Plastic steel profiles and doors and windows are important components of modern buildings, and are widely used in various buildings due to their aesthetic appearance, durability, energy saving and other characteristics. These materials not only enhance the visual appeal of buildings, but also improve the energy efficiency of buildings to some extent. With the continuous development of the construction industry, there is an increasing demand for high-performance and high-reliability building door and window materials. Plastic steel profiles, as a composite material combining the advantages of plastic and steel, have gradually become one of the mainstream choices in the market.

[0003] In order to address the problems of insufficient strength and poor weather resistance of plastic steel profiles, and to improve the overall performance of the profiles, common methods include but are not limited to the following: one is to use composite materials, that is, to combine the advantages of different materials, such as combining metal and plastic to have both the strength of metal and the corrosion resistance of plastic; two is to add additional sealing devices, such as adding sealing strips between the profiles to improve the sealing effect; three is to improve the structural design of the profiles, such as reducing heat transfer by adding thermal insulation layers, or preventing water accumulation by optimizing the drainage system. These methods have improved the performance of door and window profiles to some extent, but still have some problems.

[0004] In view of the related technology in the above, the above method solves some common problems of door and window profiles to some extent, but still has some defects. For example, the existing composite profiles are often too complex in structural design, resulting in high production cost and inconvenient installation and maintenance. In addition, although the existing sealing devices can improve the sealing performance to some extent, they are prone to aging and failure after long-term use, thereby affecting the overall performance of the doors and windows. In particular, in rainy days, rainwater can easily seep through the gaps between the profiles, causing water accumulation inside the profiles and affecting the service life of the doors and windows. Therefore, how to simplify the structural design, reduce the cost, and improve the sealing performance and waterproof performance has become a technical problem to be solved.
