Heating cigarette cooling material and preparation method and application thereof

The invention provides a heating cigarette cooling material as well as a preparation method and application thereof. The heating cigarette cooling material is prepared from the following components in parts by weight: 10 to 40 parts of polylactic acid, 1 to 10 parts of polycaprolactone, 1 to 8 parts of polyethylene glycol, 1 to 8 parts of 4-hydroxybutyrate, 1 to 5 parts of trichloromethane and 1 to 5 parts of solvent. According to the heating cigarette cooling material, polylactic acid (PLA) serves as a main phase change material, cooling is carried out according to the phase change principle, meanwhile, polycaprolactone, polyethylene glycol and 4-hydroxybutyrate are added and cooperate with one another, the long-acting cooling effect of the material can be achieved, and the mechanical strength of the material can be greatly improved. 本发明提供了一种加热卷烟降温材料及其制备方法和应用，所述加热卷烟降温材料按重量份数计包括聚乳酸10-40份、聚己内酯1-10份、聚乙二醇1-8份、4-羟基丁酸酯1-8份、三氯甲烷1-5份、溶剂1-5份。本发明的加热卷烟降温材料以聚乳酸(PLA)为主要相变材料，利用其相变原理进行降温，同时添加聚已内酯、聚乙二醇和4-羟基丁酸酯，三者协同配合，不仅可以使材
