Beschreibung
Zusammenfassung:	The invention provides a PET (polyethylene terephthalate) film for new-energy vehicle lithium battery packs.The PET film comprises a first adhesive layer, a first PET layer, a second adhesive layer, a second PET layer and a release coating, wherein each adhesive layer comprises, by weight, 80-120 parts of acrylic acid pressure-sensitive adhesive, 50-80 parts of solvent, 8-15 parts of color paste, 0.7-1.5 parts of isocyanate, 0.1-0.5 part of lithium salt, 0.1-0.5 part of retarder and 0.5-5 parts of auxiliaries, the solvent comprises 30-60wt% of ethyl acetate and 40-70 wt% of butanone, and the color paste comprises 80-85 wt% of blue paste, 10-20wt% of white paste and 1-5 wt% of yellow paste.The PET film is high in flexibility and insulativity, resistant to puncture and high temperature, good in lithium battery aluminum case adhesivity, free of residual stripping adhesive and capable of effectively protecting the lithium battery packs during driving of new-energy vehicles. 本发明提供种用于新能源汽车锂电池组的PET薄膜，其从下到上依次包括第胶粘层、第
