The application discloses a method for degrading PE pipe material by using a temperature-sensitive response two-phase molten salt catalyst. The method comprises the following steps: providing a temperature-sensitive response two-phase molten salt catalyst; the temperature-sensitive response two-phase molten salt catalyst is prepared by reacting an inorganic phase, an organic phase and an amino phosphonate coordination regulator; the inorganic phase comprises Lewis acid metal salt, alkaline earth metal halide and inert salt; the organic phase comprises temperature-sensitive quaternary ammonium salt; the PE waste pipe material is subjected to swelling treatment, then the obtained product is mixed with the temperature-sensitive response two-phase molten salt catalyst to react, and after-treatment is performed, so that the catalytic degradation of the PE waste pipe material is realized. The application firstly constructs an "organic-inorganic temperature-sensitive two-phase molten salt system", proposes a "temperature-two-phase state-active site" linkage mechanism, solves the limitation of the prior art "single phase state adapting to single plastic", and realizes the precise degradation of PE pipe materials with different crystallinities and different components by temperature regulation, without replacing the catalyst.

This invention provides a polyurethane with poly(quaternary ammonium phosphonate copper) side chains, prepared by using bis(hydroxypropyl tertiary ammonium phosphonate copper) as a functional polyol, through addition polymerization with polyisocyanates and quaternization reaction with alkylating agents. The tertiary amine group in the bis(hydroxypropyl tertiary ammonium phosphonate copper) molecular structure is characterized by quaternization reactions with halogenated hydrocarbons, and also acts as a catalyst for the addition reaction of its hydroxypropyl group with polyisocyanates, as well as an N-ligand for complexing copper ions. Furthermore, the low solubility of copper phosphonate in water allows for the formation of a polyurethane composite material with macromolecular side chains that chelate copper ions, achieving a slow-release effect of copper ions in aqueous systems. Furthermore, the quaternary ammonium cations generated by the nucleophilic substitution reaction between the tertiary amine group in the poly(hydroxypropyl tertiary aminophosphonate copper) molecular structure and halogenated hydrocarbons have hydrophilic, water-absorbing, surfactant, antibacterial and bacteriostatic functions. Combined with the phosphonate ions generated by the dissociation of copper phosphonate in water, they pair to form two phosphonium zwitterionic structural units, which is of great significance for improving the antibacterial and bacteriostatic efficacy, biocompatibility, and hydrophilicity of polyurethane.
