The invention discloses a high-temperature-resistant PP honeycomb tube and a preparation method and application thereof.The high-temperature-resistant PP honeycomb tube is composed of a plurality of PP tubes which are fixedly bonded into a whole, the inner diameter of each PP tube is 3-10 mm, and the wall thickness of each PP tube is 0.1-1 mm; the PP pipe comprises a pipe body and a bonding film layer arranged on the surface of the pipe body, the pipe body comprises the following components: PP resin, the melt index of the PP resin under the test conditions of 230 DEG C and 2.16 kg is 15-70 g/10 min, the melt index of the PP resin under the test conditions of 230 DEG C and 2.16 kg is 15-70 g/10 min, and the bonding film layer is arranged on the surface of the pipe body. The adhesive film layer comprises the following components: POE (Polyolefin Elastomer) resin, and the melting temperature of the POE resin is 100-130 DEG C; the weight ratio of the PP resin to the POE resin is (80-95): (4-15). The high-temperature-resistant PP honeycomb tube disclosed by the invention has the advantages of low odor, low content of harmful substances and recyclability, and also has excellent high-temperature mechanical properties.
