| titleOfInvention | Slow-expansion type water-swelling polyurethane sealant and preparation method thereof |
| abstract | The invention relates to the technical field of sealants, in particular to a slow-expansion water-swelling polyurethane sealant and a preparation method thereof. This slowly expand type water-swelling polyurethane sealant includes: the slow-swelling polyurethane prepolymer comprises a slow-swelling polyurethane prepolymer, a plasticizer, a filler, an adhesion promoter, a thixotropic agent, a high water-absorbent resin, a catalyst, an antioxidant and a water removal agent; the slow-swelling type polyurethane prepolymer comprises: random block polyether diol, isotactic block polyether diol, random block polyether triol, isotactic block polyether triol, polyisocyanate, plasticizer and catalyst. The preparation method of the slow-expansion water-swelling polyurethane sealant comprises the following steps: firstly, preparing a slow-swelling polyurethane prepolymer; secondly, stirring in vacuum; thirdly, drying and mixing; and fourthly, mixing and stirring. The sealant has good slow expansion effect, and is particularly suitable for sealing and waterproofing irregular gaps, such as deformation joints and post-cast strips of underground construction engineering, water supply dam construction, urban pipe gallery engineering and the like. |
