Description

technical field [0001] The invention belongs to the technical field of engineering plastics production, and in particular relates to a heat insulation strip for aluminum alloy doors and windows and a preparation method thereof. Background technique [0002] In order to achieve the purpose of energy saving, in the 1990s, my country's aluminum alloy doors and windows adopted adiabatic cold bridge technology, which is to divide the aluminum alloy door and window frame into three parts - the outer aluminum alloy frame, the inner aluminum alloy frame and the middle core connecting the inner and outer aluminum frames Part, and the middle core part, that is, the heat insulation strip, is called "insulated cold bridge". As a heat insulation strip for aluminum alloy doors and windows, it is required to have excellent mechanical properties, especially transverse tensile properties, and has the characteristics of high gloss, good dimensional stability, good thermal insulation, good fire...
