Polyurethane thermal insulation sealing element, preparation method thereof and door and window sealing structure
The invention relates to a polyurethane heat preservation and insulation sealing piece, a preparation method thereof and a door and window sealing structure. The preparation method comprises the steps that a first nylon clamping piece and a second nylon clamping piece are prepared; the first nylon clamping piece comprises a first vertical plate, a first transverse plate is arranged at the top of the first vertical plate, an upper cavity is defined by the first vertical plate and the first transverse plate, the second nylon clamping piece comprises a second vertical plate, a second transverse plate is arranged at the bottom end of the second vertical plate, a lower cavity is defined by the second transverse plate and the second vertical plate, and the upper cavity and the lower cavity are filled with the upper end and the lower end of the polyurethane core material respectively; the first nylon clamping piece and the second nylon clamping piece are put into a mold, polyurethane is poured, and after curing forming, the polyurethane heat preservation and heat insulation sealing piece is obtained; according to the preparation method of the polyurethane heat-preservation and heat-insulation sealing element, the polyurethane heat-preservation and heat-insulation sealing element is obtained, a gap between a fixed frame profile and glass is filled with the polyurethane heat-preservation and heat-insulation sealing element, the heat-preservation and waterproof effects are achieved, the heat transfer coefficient of a whole window is not affected, and it is guaranteed that the heat transfer coefficient (UF value) of a window frame body is smaller than 0.7 W/m < 2 > K.
本发明涉及一种聚氨酯保温隔热密封件、其制备方法及门窗密封结构，步骤为制备第一尼龙卡件和第二尼龙卡件；第一尼龙卡件包括第一立板，第一立板顶部设有第一横板，第一立板和第一横板围设有上空腔，第二尼龙卡件包括第二立板，第二立板底端设有第二横板，第二横板和第二立板围设有下空腔，聚氨酯芯材上下两端分别填充上空腔和下空腔；第一尼龙卡件和第二尼龙卡件放入模具中，灌注聚氨酯，固化成型后，获得聚氨酯保温隔热密封件；通过聚氨酯保温隔热密封件的制备方法的提出，获得聚氨酯保温隔热密封件，填充固定框型材与玻璃间的缝隙，起到保温防水作用，不影响整窗的传热系数，保证窗框体传热系数(UF值)小于0.7W/m2K。
