description The invention discloses a foaming sealant for space filling, which can improve the initial adhesion and the foaming rate. The foaming sealant comprises the following components by weight percentage: 25 to 30 weight percent of nitrile rubber, 10 to 15 weight percent of OBSH foaming agent, 15 to 20 weight percent of calcium carbonate filling agent, 20 to 30 weight percent of plasticizer, 1 to 5 weight percent of antiager, 5 to 10 weight percent of adhesion imparting agent, and 1 to 4 weight percent of vulcanizing agent. The foaming sealant improves the initial adhesion through the self-expansion phenomenon of the sealant, enlarges space filling force by improving the foaming rate, enlarges filling effect, and effectively improves the generation of noises during the driving of automobiles.
