Abstract

The invention relates to a modified polyactic acid composition for a cigarette filter stick and a preparation method thereof. The composition comprises following parts of raw materials, by weight, 100 parts of polyactic acid, 0.02-3 parts of polyactic acid-beta-cyclodextrin, 0.08-5 parts of sodium carbonate, 0.05-5 parts of sodium pyrrolidonecarboxylate, 0.01-4 parts of vitamin and 0.01-8 parts of polyacrylamide. The filter stick prepared through the polyactic acid composition is better in absorbing performance on smoke compared with the prior art and good in comprehensive performance, and a part of indexes of the filter stick exceed those of a cellulose acetate filter stick.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to a modified polylactic acid composition for cigarette filter rods and a preparation method thereof. Background technique [0002] The development of filter tip is the product of cigarette development to a certain stage. When the filter first appeared, it was mainly used as a mouth-shaped part of the cigarette for decoration. With the development of cigarette technology and people's pursuit of low-harm cigarettes, the filter has gradually changed from a dispensable position to an indispensable part of cigarettes, and has assumed the function of reducing tar and harm. [0003] Cigarette filters have the functions of filtering, blocking and absorbing harmful components such as nicotine and tar in the smoke. In addition to the above functions, a good filter should also be able to improve the taste of the smoke, reduce the stimulation of the smoke on the mouth and the human body. Hea...
