Abstract

The invention discloses a low-moisture permeability light thermal-insulation material. The low-moisture permeability light thermal-insulation material comprises polyethylene foamed plastic and aluminum foil hot-pressed to upper and lower surfaces of the polyethylene foamed plastic. The polyethylene foamed plastic comprises, by mass, 90-95% of polyethylene resin, 1-2% of a cross-linking agent, 1-6% of a foaming agent and 1-3% of a stabilizing agent. The polyethylene foamed plastic has a microporous cellular inner structure and has cellular pore sizes of 0.01-0.05 micrometers and the cellular pores are filled with air. The low-moisture permeability light thermal-insulation material has excellent water tightness and steam separation performances and has light weight, good endurance and long thermal-insulation time.
