Abstract: This paper provides an in-depth study around the adhesive properties and influencing factors of PSP. First, based on the background of material science and composite pipe technology, the preparation method of metal mesh skeleton and plastic composite material is emphasized, including the selection and structural design of the metal mesh skeleton, and the performance analysis and suitability assessment of the plastic material, to assure that the composite pipe has highly efficient bonding performance. The adhesive properties of PSP were also discussed in depth, and the bonding performance of the composite pipe at different stages was evaluated by sorting out the mechanical principle of bonding and chemical reaction mechanism, and combining with advanced testing methods, such as thermal analysis and mechanical stretching. Finally, the paper detailed analysis of the multiple factors affecting the adhesive properties of PSP. It provides scientific basis and technical guidance for improving the production process and use performance of PSP.
