According to the battery pack, the battery cell module and the bottom wall are arranged at an interval, and the heat insulation part is arranged between the battery cell module and the bottom wall, so that on one hand, the heat insulation part can reduce heat transferred to the bottom wall by the battery cell module during thermal runaway, and on the other hand, the heat insulation part has a fireproof function, and the risk that the bottom wall is directly burnt when the battery cell module is on fire is reduced.

This invention discloses a water-based coating with fire-retardant and thermal insulation functions, its preparation method, and its application, relating to the field of water-based coatings. This water-based coating with fire-retardant and thermal insulation functions, through an innovative raw material ratio, combines inorganic and organic flame retardants, along with surface-treated insulating glass microspheres and a specific ratio of inorganic hybrid emulsion, successfully enabling the coating to simultaneously possess excellent fire-retardant and thermal insulation properties. Test results of Examples 1-3 show that the coatings all achieve a 1-hour fire resistance rating, with the lowest thermal conductivity reduced to 0.042 W / (m·K), far exceeding the performance of the control example, which only possesses basic fire-retardant functions and insufficient thermal insulation performance. When this multifunctional coating is applied to building exteriors, industrial equipment surfaces, and vehicle interiors, it can effectively prevent the spread of fire, ensure personnel safety, reduce energy consumption, and improve energy efficiency.
