The invention belongs to the technical field of polyurethane foam plastic, and particularly relates to high self-adhesive environment-friendly combined polyether for stainless steel freezer cabinets,a preparation method and application thereof. The combined polyether is prepared from the following raw materials in parts by weight: 20 to 50 parts of polyether polyol I; 20 to 30 parts of polyetherpolyol II, 30 to 50 parts of polyether polyol III, 10 to 15 parts of an additive, 0.2 to 0.6 part of a catalyst I, 1.0 to 2.0 parts of a catalyst II, 0.5 to 1.5 parts of a catalyst III, 0.5 to 1.0 part of a catalyst IV, 5 to 10 parts of a foam stabilizer, 2.1 to 3.1 parts of water, and 26 to 36 parts of a foaming agent. The preparation method is simple, and foam prepared by the reaction of the combined polyether and crude MDI has high compressive strength, good dimensional stability, low thermal conductivity, and high bonding strength with stainless steel plates. The foam performance meets therequirements of use, and has the characteristics of zero DOP, low GWP and good environment-friendly performance.
