The invention provides a degradable material for preparing a cooling pipe. The degradable material is prepared from the following components in parts by mass: 10 to 50 parts of modified multi-walled carbon nanotubes, 15 to 70 parts of a phase change material, 50 to 80 parts of a biodegradable material and 0 to 10 parts of a hydrated salt compound, the modified multi-walled carbon nanotube is a hydroxylated multi-walled carbon nanotube modified by sodium p-methylstyrene sulfonate. The modified multi-walled carbon nanotubes are introduced into the degradable material, the modified multi-walled carbon nanotubes have a crystallization induction effect on the biodegradable material, the crystallization performance is improved to achieve the energy storage effect of the phase change material, and the effect of reducing the smoke temperature of the heat-not-burn cigarette is remarkable. 本发明提供了一种用于制备降温管的可降解材料，包括以下质量份的组分：改性多壁碳纳米管10-50份、相变材料15-70份、生物可降解材料50-80份、水合盐类化合物0-10份；所述改性多壁碳纳米管为对甲基苯乙烯磺酸钠改性的羟基化多壁碳纳米管。本发明向可降解材料中引入
