The invention discloses a basalt nano high-temperature sealant which comprises the following components: a matrix resin, a telechelic polymer, basalt powder, a vulcanizing agent and a cross-linking agent; and the basalt nano high-temperature sealant comprises the following components in parts by weight: 21-30 parts of the matrix resin; 35 to 45 parts of the telechelic polymer, 40 to 60 parts of basalt powder, 5 to 10 parts of the vulcanizing agent, and 2 to 7 parts of the cross-linking agent. According to the technical scheme, the telechelic polymer is added into the sealant, so that the telechelic polymer can be crosslinked into a net structure under the conditions of the vulcanizing agent and heating, the problem that the sealant becomes thin and sticks to a mold at high temperature is solved, and the structural strength of the sealant and the form stability of the sealant in a high-temperature environment can be greatly improved by taking basalt powder as a filler. 本发明涉及一种玄武岩纳米高温密封胶，包括如下组分：主体树脂、遥爪聚合物、玄武岩粉末
