Description

Technical Field

[0001] The utility model belongs to the field of aluminum profiles, and in particular relates to a novel thermally-insulated aluminum alloy profile. Background Art

[0002] The "bridge" in the name "broken bridge aluminum" refers to the "cold-hot bridge" in the materials science sense, while the "break" refers to the act of interrupting the bridge. Because aluminum alloy is a metal with high thermal conductivity, when there is a large temperature difference between indoor and outdoor, the aluminum alloy acts as a "bridge" for heat transfer, resulting in poor thermal insulation performance of doors and windows. Broken bridge aluminum is achieved by severing the aluminum alloy in the middle and connecting the broken parts with hard plastic, thus blocking the heat transfer path and improving the material's thermal insulation performance.

[0003] The current production process of thermal break aluminum profiles uses a rolling machine to insert nylon strips into the aluminum alloy. Although the existing thermal break aluminum processing technology is relatively mature, the processing cost is also relatively high, mainly in the rolling machine, site fees, labor costs, material costs and other costs, making processing costs the main obstacle to current market competition. In order to improve the competitiveness of products, the development of new aluminum profiles is urgently needed by existing companies. Utility Model Content
