Waterborne polyurethane foaming and foam stabilizing aid and preparation method thereof

The invention discloses a waterborne polyurethane foaming and foam stabilizing aid and a preparation method thereof, and the waterborne polyurethane foaming and foam stabilizing aid comprises the following components in parts by weight: 10-20 parts of ethoxylated organosilicon compound; 25 to 45 parts of alkyl polyglucoside; 10 to 25 parts of a span emulsifier; 5 to 10 parts of high alcohol; 0.1-1 part of a preservative; and 80 to 160 parts of deionized water. According to the invention, the ethoxylated organosilicon compound and the alkyl polyglucoside mainly play a foaming role; the Span emulsifier and the higher alcohol play foam stabilizing and thickening roles, so that the waterborne polyurethane foam stabilizer can play roles of a foaming agent and a foam stabilizer at the same time, extremely fine and uniform foam holes can be formed through mutual consideration of the dosages of the foaming and foam stabilizing components, and the high stability of foam is kept; the cost is low. 本发明公开一种水性聚氨酯发泡稳泡助剂及其制备
