Composite thermal insulation material integrally formed with battery shell and preparation process of composite thermal insulation material
The invention provides a composite thermal insulation material integrally formed with a battery shell, wherein the composite thermal insulation material comprises an aerogel material and inorganic fibers, the mass ratio of the aerogel material is 0.5%-60%, and the mass ratio of the inorganic fibers is 40%-99.5%. The invention has the following beneficial effects: the aerogel has low thermal conductivity due to the unique network structure and high porosity of the aerogel, but the internal pore size distribution of the aerogel is non-uniform, the pressure difference between pores is large, and the internal structure is easy to deform and crack; in this way, through integral forming, the auxiliary supporting effect of the additive can be fully utilized, and the macroscopic deformation of the aerogel material in the thermal battery assembly process is avoided, so that the unique pore structure in the aerogel is maintained, and the thermal insulation performance of the aerogel is fully exerted.
本发明提供一种与电池壳体一体成型的复合保温材料，包括：气凝胶材料和无机纤维，其中，所述气凝胶材料的质量占比为0.5％‑60％，所述无机纤维的质量占比为40‑99.5％。本发明的有益效果是气凝胶独特的网络结构和高孔隙率使其具有低热导率，但气凝胶内部孔径分布不均，孔与孔间的压力差大，内部结构易发生变形破裂，通过一体成型，可以充分利用添加剂的辅助支撑作用，并避免气凝胶材料在热电池装配过程中的宏观变形，维持气凝胶内部的独特孔结构，充分发挥其绝热保温性能。
