▎ 摘  要

NOVELTY - A polysulfide sealant comprises 1-20 pts. wt. polyether trihydric alcohol, 1-15 pts. wt. sulfur alcohol, 1-30 pts. wt. isocyanate, 1-26 pts. wt. liquid polysulfide, 1-18 pts. wt. graphene oxide, 1-10 pts. wt. propylene oxide butyl ether, 1-20 pts. wt. acrylic ester emulsion , 1-28 pts. wt. phenolic resin, 1-9 pts. wt. dibutyl(sic), 5-80 pts. wt. filler, 0.5-6 pts. wt. tackifier, and 1-10 pts. wt. plasticizer. USE - Polysulfide sealant. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparing the sealant comprising mixing and kneading the raw materials, stirring for 20-30 minutes at 30-50 degrees C, adding filler, tackifier, and plasticizer, pumping vacuum and heating slowly to 50-60 degrees C, keeping vacuum, heat preserving and stirring for 1-2 hours, cooling, and filtering.
