Abstract

The invention discloses sealing heat-insulating foam filler for aluminum alloy door and window. The filler includes: 30-35 parts of polyurethane, 8-10 parts of zinc dimethyldithiocarbamate, 10-25 parts of acetone, 10-13 parts of CaCO3, 2-4 parts of polyvinyl acetate, 4-6 parts of polyether polyol, 5-8 parts of lauryl sodium sulfate, 3-4 parts of zinc stearate, 1-3 parts of ammonium sulfate, 3-7 parts of azodicarbonamide, 8-13 parts of rosin, 2-4 parts of bisdimethylaminoethyl ether, 2-4 parts of dipropylene glycol, 4-8 parts of dibutyl phthalate and 2-4 parts of diethylidenetriamine. In the foam filler, through the additives such as polyether polyol, lauryl sodium sulfate and ammonium sulfate, the physical properties of the polyurethane foam filler is enhanced, so that the product has stronger adhesion force, is rapid to foam and solidify, has certain thermal resistance, can fill and fit the gap between the aluminum alloy door and window and wall well, and has sealing and heat-insulating effect.

Description

technical field [0001] The invention relates to the field of building decoration materials, in particular to a sealing and heat-insulating foam filler for aluminum alloy doors and windows. Background technique [0002] As the mainstream of the market, polyurethane foam filler has a wide adjustable range of performance, strong adaptability, good wear resistance, and high mechanical strength. Inversely correlated, that is, the higher the degree of pollution, the worse the adhesion and bonding effect. In the process of filling and bonding the gap between aluminum alloy doors and windows and the wall, polyurethane foam is very easy to produce gaps when the adhesion state is not good, resulting in poor installation of doors and windows, and the gaps indirectly lead to indoor space damage. poor insulation effect. In addition, the texture of polyurethane is brittle after filling and molding. After long-term use of door frames and other parts, it is easy to cause the foam polymer ...
