The invention provides a method for preparing a tobacco base material high in
smoke loading capacity and incombustible after heating. Water is added into cigarette waste tobacco, standby
slurry is formed through pulping after stirring and soaking, then needlebush pulp and
hardwood pulp are prepared, the standby
slurry with the weight accounting for 40-60% that of over-dried substances is added into a
slurry mixing tank, then the needlebush pulp with the weight accounting for 20-30% that of over-dried substances and the
hardwood pulp with the weight accounting for 10-30% that of over-dried substances are added, the materials are stirred to obtain mixed slurry, the mixed slurry is diluted, then diatomite,
activated carbon and
guar gum are added, and formed slurry is obtained; a base material with the over-
dry weight being 40-60 g / m<2> is obtained after the formed slurry is formed by a former and dehydrated, the base material is dried,
cut and coiled, and the tobacco base material is obtained. The prepared incombustible tobacco base material can absorb a large number of low-temperature volatile flavoring components extracted from tobacco, and can generate a large amount of tobacco
flavor under the
combustion-free low-temperature heating condition, and compared with traditional
combustion-smoking type cigarettes, the base material is good in similarity in the aspect of
smoke and taste, sufficient in fragrance and good in coordination.
