Nano aerogel fireproof felt for new energy automobile battery and processing device thereof
The invention discloses a nano aerogel fireproof felt for a new energy automobile battery, and belongs to the technical field of battery packaging. The nano aerogel fireproof felt is prepared by the steps that a dilute acid solution and a dilute alkali solution are subjected to a replacement reaction and modification to obtain a composite aerogel, the composite aerogel is immersed in felt, the combined part of the composite aerogel and the felt is used as a middle layer, and PP-GF glass fabric is added to the upper layer and the lower layer of the composite aerogel for bonding to form the nano aerogel fireproof felt with a sandwich structure. According to the invention, the composite aerogel obtained by using the dilute acid solution and the dilute alkali solution through solvent replacement and modification is uniform in pore distribution and good in mechanical property, and the mass percentage of the aerogel composite material is 15-22%, so that the nano aerogel fireproof felt can adapt to high-temperature, compression, vibration and other environments, has the characteristics of environmental protection, no odor, fire prevention, low thermal conductivity and the like, and achieves a good heat insulation effect.
