Description

Aluminum-plastic aluminum door and window sealing device

technical field

The utility model relates to an aluminum-plastic-aluminum door and window sealing device, which belongs to the technical field of aluminum-plastic-aluminum door and window sealing.

Background technique

At present, the profiles used in building doors and windows are mainly plastic profiles and aluminum profiles. Plastic profiles have low bending strength, poor impact resistance, and are easy to fade. After long-term use, not only the surface turns yellow, but also tends to age and become brittle or deformed; Profiles have poor thermal insulation ability, poor sound insulation and noise reduction performance, poor airtightness and watertightness. Therefore, building doors and windows made of aluminum-plastic-aluminum composite profiles have gradually appeared on the market. Aluminum-plastic-aluminum composite profiles combine plastic profiles and aluminum profiles. Advantages, so that their advantages complement each other, and various performances are improved. However, the existing aluminum-plastic-aluminum doors and windows are mainly sealed on the inner and outer sides of the doors and windows. With this sealing structure, the sealing and noise reduction effects are relatively poor.
