Embodiment 1

[0029] A method for surface treatment of heat-insulating and corrosion-resistant aluminum alloy doors and windows, comprising the steps of:

[0030] 1) Cut the two ends of the aluminum alloy profile 1 that needs to be framed to 45°, and set a dovetail at both ends of the aluminum alloy profile 1;

[0031] 2) Connect four aluminum alloy profiles 1 end-to-end, and use dovetail joints to connect the four pieces by extrusion to form a frame;

[0032] 3) polishing the outer surface of the frame;

[0033] 4) Mix epoxy resin glue, silicon dioxide, calcium silicate and coupling agent in the following parts by weight to obtain a low-melting adhesive layer paste: 30 parts of epoxy resin, 12 parts of silicon dioxide, 10 parts of silicon carbide Parts, 10 parts of coupling agent;

[0034] 5) Apply the adhesive layer paste evenly on the outer surface of the frame, and air-dry it at room temperature, and then use a laser beam at 500°C to anneal the adhesive layer paste to form an adhesive...

Abstract

The invention discloses a heat insulation and corrosion resistant aluminum alloy door window surface treatment method. The heat insulation and corrosion resistant aluminum alloy door window surface treatment method totally comprises nine steps. The outer surface of an aluminum alloy door window is treated by adopting the mode that assembly and polishing are conducted firstly and then coating is conducted, damage to a coating layer on the outer surface in the assembly process is avoided, and thus the integrity of the coating layer is ensured; it is ensured that functional layers cannot permeateto one another through the mode of layer-by-layer coating, and the functionality of the coating layer is ensured; annealing treatment is conducted by adopting lasers, operation can be conducted moreflexibly, and large-size annealing equipment is not needed; and a heat insulation layer is arranged in the middle so that heat generated in the annealing process can be effectively prevented from being transmitted to the aluminum alloy door window, and accordingly the aluminum alloy door window is protected effectively.

Description

technical field [0001] The invention relates to the field of surface treatment of aluminum alloy doors and windows, in particular to a heat-insulating and corrosion-resistant surface treatment method of aluminum alloy doors and windows. Background technique [0002] Aluminum alloy doors and windows refer to doors and windows made of aluminum alloy extruded profiles as frames, stiles, and fans. They are called aluminum alloy doors and windows, or aluminum doors and windows for short. Aluminum alloy doors and windows include doors and windows made of aluminum alloy as the base material of the force-bearing rod (the rod that bears and transmits its own weight and load), and wood and plastic composite doors and windows, referred to as aluminum-wood composite doors and windows, aluminum-plastic composite doors and windows. The quality of aluminum alloy doors and windows can be roughly judged from the selection of raw materials (aluminum profiles), the surface treatment of aluminu...
