| Abstract: | The preparation of the onecomponent polyurethane sealant was studied. And the molecular weight of polyether, the content of fillers and catlyst on the properties of the polyurethane sealant was also investigated. Selecting the suitable polyol and diisocyanate, with the appropriate proportion, the sealant could be synthesized. And its property is as good as that of the same products made in foreign countries. And it can also meet the demands of industrialization manufacture. |
