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.
