Room-temperature vulcanized fluororubber sealant

The invention discloses a room-temperature vulcanized organic fluororubber sealant which is prepared from two components, namely base paste and vulcanized paste. The base paste comprises fluororubber,a mixed solvent, an acid acceptor, a reinforcing agent and a tackifier; and the vulcanized paste comprises a fluororubber vulcanizing agent and a solvent. The sealant is good in mechanical property and excellent in fuel oil resistance, the use temperature range can be adjusted according to fluororubber types, and the sealant is a good aviation sealant. 本发明公开一种室温硫化有机氟橡胶密封剂，它是由基膏和硫化膏两个组分制备而成。其中基膏包含氟橡胶，混合溶剂，吸酸剂，补强剂，增粘剂；硫化膏包含氟橡胶硫化剂，溶剂。该密封剂力学性能良好，耐燃油性能优异，可根据氟橡胶胶种调节使用温度范围，是一种良好的航空密封剂。
