Technical Field

[0001] The utility model relates to the technical field of sealed window frames, in particular to a window frame comprising a C-shaped foamed EPDM rubber strip. Background Art

[0002] Water tightness and air tightness are the main performance indicators of the connection between door and window frames. In order to achieve these two indicators, the sealing design between the door and window frames is the key. For fixed door and window frames, a good sealing effect can be achieved by using sealants; for doors and windows that need to be opened, sealing strips are mainly used to seal between the door and window frames.

[0003] After searching, the utility model patent with Chinese patent publication number CN216788232U discloses a weather-resistant sealing strip for door and window frames, including a sealing strip body, the sealing strip body including a base layer, the top of the base layer is fixedly connected with a first functional layer, the first functional layer includes an EPDM rubber layer and a silicone rubber layer, the bottom of the base layer is fixedly connected with a second functional layer, the second functional layer includes a nitrile rubber layer and a chloroprene rubber layer; although the device improves the sealing effect of the strip body, in actual use, the service life of the strip is limited, and it only relies on glue to stick it, resulting in a lack of fixing effect and easy falling off.
