Problems solved by technology

Existing insulation strips for broken bridge aluminum use PA66 heat insulation strips. Although PVC heat insulation strips appear on the market to save production costs, the heat insulation effect, heat resistance and aging resistance of PVC heat insulation strips are better than those of PA66 insulation strips. The difference of the hot strip can shorten the service life of the broken bridge aluminum profile

Abstract

The invention relates to the technical field of bridge-cut-off aluminum profiles, in particular to a bridge-cut-off aluminum profile and a preparation method thereof. The bridge-cut-off aluminum profile comprises a first aluminum alloy component, a second aluminum alloy component and a heat insulation strip arranged between and connected with the first aluminum alloy component and the second aluminum alloy component, wherein hook-shaped embedded blocks extend from the two sides of the heat insulation strip, and the hook-shaped embedded blocks on the two sides of the heat insulation strip are fixedly connected with the first aluminum alloy component and the second aluminum alloy component correspondingly. The heat insulation strip comprises the following raw materials: polyvinyl chloride, nitrile rubber powder, glass fibers, graphene, a cross-linking agent, a cross-linking activating agent, a hydrolysis-resistant agent and an antioxidant. According to the bridge-cut-off aluminum profile, the stability of the bridge-cut-off aluminum profile is improved through the hook-shaped embedded blocks of the heat insulation strip; the heat insulation strip uses polyvinyl chloride as a main rawmaterial, so cost is lower than the cost of a PA66 raw material; and other raw materials are added to jointly improve the heat insulation property, toughness and environmental aging resistance of theheat insulation strip, so the service life and heat insulation effect of the bridge-cut-off aluminum profile are improved.

Description

technical field [0001] The invention relates to the technical field of broken bridge aluminum profiles, in particular to a broken bridge aluminum profile and a preparation method thereof. Background technique [0002] Broken bridge aluminum is also called heat-insulated broken bridge aluminum profile, heat-insulated aluminum alloy profile, broken bridge aluminum alloy, broken cold and hot bridge profile, and broken bridge aluminum-plastic composite profile. It has better performance than ordinary aluminum alloy profiles. [0003] The principle of the heat-insulating broken bridge aluminum alloy is to penetrate the heat-insulating strip in the middle of the aluminum profile, break the aluminum profile to form a broken bridge, and effectively prevent heat conduction. The existing thermal insulation strips for broken bridge aluminum mostly use PA66 heat insulation strips. Although PVC heat insulation strips appear on the market to save production costs, the heat insulation eff...
