The present invention relates to the technical field of aerogel fibers, and more specifically, to a heat-generating and heat-insulating nano-aerogel fiber and a method for preparing the same, comprising the following components: a composite aerogel, a modified wool fiber, and a phase change material. The addition of borides can absorb infrared radiation and convert it into heat energy, thereby improving the heating efficiency of the fiber; borides can also enhance the infrared emission capability of the fiber itself. When the fiber temperature rises, it can better dissipate heat in the form of infrared radiation, maintaining a warm environment around it. Vanadyl acetylacetonate can enhance the structural stability of the aerogel through synergistic effects with other materials, allowing it to maintain good mechanical properties under multiple cycles of compression, torsion, and other loads.

The invention relates to the technical field of barrier explosion suppression materials, in particular to a barrier explosion suppression material with mildew resistance and a preparation method and application thereof. The invention discloses a barrier explosion suppression material with mildew resistance. The barrier explosion suppression material is prepared from the following raw materials in parts by weight: 50-80 parts of polytetramethylene ether glycol, 10-20 parts of polybutylene adipate glycol, 0.1-0.2 part of a catalyst, 1-2 parts of isocyanate, 4-5 parts of a foaming agent, 4-5 parts of an anti-mildew agent, 5-8 parts of a chain extender and 2-4 parts of a stabilizer. According to the barrier and explosion suppression material, the antifungal agent and the polyhydric alcohol component are used in a composite mode, the lasting antifungal performance of the barrier and explosion suppression material is achieved, the prepared barrier and explosion suppression material also has the explosion suppression performance and the fuel oil compatibility, and the problem that an existing barrier and explosion suppression material is prone to mold breeding in a humid or warm environment is solved.

The invention relates to the technical field of aerogel fibers, in particular to a heating and warm-keeping nano aerogel fiber and a preparation method thereof, and the heating and warm-keeping nano aerogel fiber comprises the following components: composite aerogel, modified wool fiber and a phase change material. The added boride can absorb infrared radiation and convert the infrared radiation into heat energy, so that the heating efficiency of the fiber is improved; the boride can also enhance the infrared emission capability of the fibers, and when the temperature of the fibers rises, heat can be better dissipated in an infrared radiation mode, and the surrounding warm environment is maintained. The vanadyl acetylacetonate can enhance the structural stability of the aerogel through the synergistic effect with other materials, so that the aerogel can still keep good mechanical properties under loads such as multiple cyclic compression and distortion.

The invention provides a heat preservation and water storage device for vegetation planting in a lignite mining area, which comprises an annular protective cylinder, an annular heater mounted on the inner side of the annular protective cylinder, a shielding ring net mounted at the top end of the annular protective cylinder, a water storage ring cavity formed in the inner side of the annular protective cylinder, and a plurality of drainage holes formed in the inner wall of the annular protective cylinder, the water storage ring cavity irrigates soil in the inner space of the annular protection cylinder through the drainage holes; one side of the annular heater is connected with the inner space of the water storage annular cavity, and the annular heater can heat soil on the inner side and a water source in the water storage annular cavity together. Soil and a water source can be heated, the soil temperature is increased, a warm environment is created for vegetation roots, cold in a mining area is resisted, and the survival rate of seedlings is increased; soil in the annular protection barrel is irrigated through the water storage annular cavity and the drainage holes formed in the inner wall, water is provided for vegetation, the drought condition of the mining area is improved, the water retention capacity of the soil is enhanced, vegetation growth is guaranteed, and carbon sequestration of the vegetation can be achieved through photosynthesis and the root system carbon sequestration effect.
