The invention discloses a temperature-resistant and easy-to-peel CPP protective film, an adhesive tape and a preparation method thereof, which comprises a temperature-resistant and easy-to-peel CPP protective film. The protective film comprises a CPP film, a temperature-resistant and easy-to-peel adhesive layer and a release material layer. The CPP film is a steaming-resistant CPP film; the release material layer is an organic silicon release material prepared by a method in the prior art; the temperature-resistant easy-to-peel adhesive layer is prepared from 100 parts of acrylate adhesive; the acrylate adhesive is prepared from the following components in parts by weight: 10 parts of butyl acrylate, 90 parts of 2-ethylhexyl acrylate, 9 parts of acrylic acid, 0.9 part of 4-hydroxybutyl acrylate, 0.9 part of vinyl acetate, 0.09 part of azodiisobutyronitrile and 180 parts of methylbenzene. According to the invention, the high temperature resistance of the protective film adhesive tape isimproved, the phenomena
