More Information
Summary:The invention relates to a foamed polyolefin thermal insulation material for a cold region tunnel and application and a construction method thereof, and the foamed polyolefin thermal insulation material for the cold region tunnel comprises the following raw materials in parts by mass: 60-80 parts of polyethylene, 3-5 parts of nanoscale aluminum hydroxide, 6-8 parts of polypropylene, 15-25 parts of a flame retardant, 20-30 parts of a foaming master batch and 5-8 parts of a silane coupling agent; the flame retardant is tubular polyphosphazene coated with hexadecyl trimethyl ammonium chloride and sodium lignin sulfonate; the foaming polyolefin thermal insulation material is used for constructing a cold region tunnel structure, the flame-retardant and thermal insulation effects are good, the tunnel structure construction method enables layers to be tightly attached, air and water are prevented from entering the tunnel structure to the maximum extent, and invasion of seepage water frost heaving force is reduced. 本
