The invention relates to the technical field of sodium metal batteries, and discloses a composite negative electrode for a low-temperature sodium metal battery, which comprises sodium metal and NaF embedded on the surface or inside the sodium metal, the preparation method comprises the following steps: S1, preparing NaF powder by adopting a freeze-drying method; and S2, rolling the NaF powder prepared in the step S1 into a metal sodium foil by adopting a mechanical rolling mode to prepare the NaF-Na composite negative electrode material. According to the technical scheme, the problems that in the prior art, the preparation process is complex, danger is high, and mass production cannot be achieved can be solved, and meanwhile it is ensured that the composite negative electrode has high specific discharge capacity and excellent cycle performance in the low-temperature environment.

The utility model relates to a flexible and easy-to-bend gap five-layer pipe which is characterized by comprising a lining pipe, a flat steel wire spring layer is armored outside the lining pipe, flat steel wires of the flat steel wire spring layer are uniformly armored outside the lining pipe in a gap mode, a straight steel wire layer is arranged outside the flat steel wire spring layer, a reinforcing flat belt layer is arranged outside the straight steel wire layer, and the reinforcing flat belt layer is arranged outside the straight steel wire layer. A plastic-coated layer is arranged outside the reinforcing flat belt layer, the direction of the flat steel wire spring layer is right-handed rotation, the direction of the straight steel wire layer is left-handed rotation, and the direction of the reinforcing flat belt layer is right-handed rotation. Due to the arrangement of the armored flat steel wire spring layer, compared with a conventional structure, the gap five-layer pipe of the structure is excellent in bending performance and soft. After cutting, the lining pipe and the plastic coating layer have no obvious core shrinkage phenomenon, the steel wire has no obvious protruding phenomenon, and the assembling efficiency and the service life of the sheath pipe are guaranteed.

The invention discloses a high-temperature-resistant heat-proof coating material and a preparation method thereof, and aims to solve the problems that the existing organic heat-proof coating material is poor in shape maintaining property and insufficient in mechanical strength at high temperature. The coating material disclosed by the invention is prepared from the following raw materials in parts by mass: 0.5 to 5 parts of octa-aminopropyl polyhedral oligomeric silsesquioxane, 80 to 120 parts of hydroxyl-terminated polymethylphenylsiloxane, 3 to 12 parts of curing agent, 0.1 to 5 parts of catalyst, 20 to 80 parts of low-temperature bonding glass material and 20 to 80 parts of high-temperature melt eutectic mineral aggregate. By increasing the rigidity of the matrix resin and combining the characteristics of the low-temperature bonding glass material and the high-temperature melting eutectic mineral material, the organosilicone heat-proof coating capable of being vitrified at high temperature is prepared, and then the shape maintaining property and the mechanical property of the protective material in a wide temperature range are improved.
