Abstract
A composite aluminum alloy profile and a preparation method therefor. The composite aluminum alloy profile includes an outer decorative profile, a polyurethane elastomer structural adhesive, and an inner frame profile. The inner frame profile is an integral component of alkali-free glass fibers and polyurethane resin formed by one-time extrusion, and the inner frame profile comprises one upper closed cavity and one lower closed cavity for a total of two cavities and a reinforced heat insulation rib plate between the upper closed cavity and the lower closed cavity; and the outer decorative profile is connected to the inner frame profile through the polyurethane elastomer structural adhesive. The preparation method includes: preparing glass fibers and polyurethane materials of components A and B into a glass fiber resin reinforced profile by a compound strip-threading and injection machine, adhering the inner frame profile to the outer decorative profile through the polyurethane elastomer structural adhesive, and rolling the same. The profile has the features of heat and sound insulation and is easy to produce.
