Aluminum alloy door and window seam plugging method for coastal areas

Abstract

The invention discloses an aluminum alloy door and window seam plugging method for coastal areas. The method comprises the following steps that an aluminum alloy door and window installation hole is cleaned and trowelled, hot air drying treatment is carried out, a waterproof coating is brushed to form a first waterproof layer, the waterproof coating is brushed to form a second waterproof layer, analuminum alloy door and window is installed, waterproof roll construction and polyurethane foaming adhesive filling are carried out in a seam, a sealant is injected into an installation gap, and thewaterproof coating is brushed in the installation gap. According to the method, the aluminum alloy door and window installation hole is cleaned and subjected to hot air drying, so that the combinationtightness between the subsequent seam filling material polyurethane foaming adhesive and the aluminum alloy door and window installation hole can be improved, and a water seepage channel is avoided;and the seam is filled alternately in a mode of laying the waterproof roll and filling the polyurethane foaming adhesive during seam filling, so that the tightness of the filled seam can be improved,the water seepage prevention capacity of the filled seam is greatly improved, and the filled seam can effectively adapt to the coastal strong wind and rain environment.

Description

technical field [0001] The invention relates to the technical field of installing aluminum alloy doors and windows, in particular to a method for plugging aluminum alloy doors and windows in coastal areas. Background technique [0002] Aluminum alloy doors and windows refer to doors and windows made of aluminum alloy extruded profiles as frames, stiles, and fan materials. They are called aluminum alloy doors and windows, referred to as aluminum doors and windows. Composite doors and windows, referred to as aluminum-wood composite doors and windows, aluminum-plastic composite doors and windows.

[0003] Water seepage after caulking of aluminum alloy doors and windows has always been a relatively common phenomenon in the quality of housing construction projects. In the existing treatment of aluminum alloy doors and windows, polyurethane foam is generally used for filling, but for coastal areas , there will often be extremely heavy wind and rain, and the bonding stability of polyurethane foam in the gaps will be destroyed under strong winds, resulting in larger gaps in aluminum alloy doors and windows, and an increase in the incidence of water seepage. Therefore, the present invention proposes a Aluminum alloy door and window plugging method in coastal areas to solve the deficiencies in the prior art
