The invention discloses a cooling and filtering material as well as a preparation method and application thereof. 
Plant fiber dispersion liquid and PLA 
fiber dispersion liquid are evenly mixed, then 
papermaking is conducted, then calendaring is conducted, and the cooling and filtering material is obtained. Good folding resistance and high-
temperature resistance of 
plant fibers are fully utilized,the 
plant fibers support the 
composite material, the 
fracture problem of a 
polylactic acid film in the folding and rolling process is solved, and the problems that 
polylactic acid serves as a coolingmaterial, contracts and collapses as a 
phase change material after absorbing heat and blocks a 
smoke channel are solved; the filtering effect, namely the filtering performance, generated by the adsorption and interception effects of the adopted 
plant fibers is reduced, so that the cooling and filtering material is more suitable for producing non-combustible cigarettes with smaller 
smoke generationamount, the 
aroma saturation of 
smoke is favorably improved, and the smoking experience is improved. The cooling section and the filtering section are combined into one section, so that the cooling section is longer, and the 
cooling effect is better. Meanwhile, the production cost is reduced, and the production process is simplified.
