| titleOfInvention | Low-modulus MS sealant for assembly type building outer wall and preparation method thereof |
| abstract | The invention relates to a low-modulus MS sealant for an assembly type building outer wall, and a preparation method thereof. The adhesive is prepared by mixing 40-60 parts by weight of silane modified polyether, 20-45 parts by weight of inorganic filler, 10-15 parts by weight of thixotropic agent, 10-15 parts by weight of plasticizer and 0.5-1.5 parts by weight of silane coupling agent. The high molecular weight silane terminated polyether is successfully prepared by adopting terminal alkenyl polyether, bifunctional secondary amine compound and terminal hydrogen silane through Michael addition reaction and hydrosilylation reaction. The synthetic route has mild reaction conditions, simple and convenient process and no by-product. Based on the silane terminated polyether, the MS sealant with excellent comprehensive performance can be prepared. The product does not contain a urethane bond in a molecular chain, is crosslinked through a Si-O-Si bond, has excellent weather resistance, and can be applied to the caulking of the outer wall of an assembled building. |
