Beschreibung
Zusammenfassung:	The utility model discloses an acrylic acid modified waterborne polyurethane preparation device which comprises a reactor and a neutralizer which are sequentially connected, and further comprises a first heating mechanism and a steam removal mechanism, the first heating mechanism is used for heating the neutralizer; and the steam removal mechanism is used for removing steam in the neutralizer. After the neutralizer is heated, water is evaporated to form steam, and then the steam is discharged through the steam mechanism, so that the water content of a product in the neutralizer can be effectively reduced. 本实用新型公开了一种丙烯酸改性水性聚氨酯制备装置，包括依次连接的反应器和中和器，其中，还包括第一加热机构和蒸汽除去机构；所述第一加热机构用于使所述中和器升温；所述蒸汽除去机构用于除去所述中和器内的蒸汽。所述中和器升温后水分蒸发形成蒸汽，然后通过蒸汽机构排出，可以有效地降低中和器内产物的水含量。
