Composition of thermoplastic starch, natural colloid and polymer as well as preparation method and application of composition

Abstract

The invention relates to a composition of thermoplastic starch, natural colloid and a polymer as well as a preparation method and application of the composition in a cigarette filter rod, and belongsto the technical field of cigarettes. The method comprises the following three steps: preparation of the thermoplastic starch, preparation of a natural colloidal aqueous solution, and preparation of the composition of the thermoplastic starch, the natural colloid and the polymer. According to the method provided by the invention, the composition of the thermoplastic starch, the natural colloid andthe polymer is used as a substrate, flavor substances and pigments are selectively added, and a linear solid with a fixed form is directly formed on the axis of a filter rod, which is different froman existing filter rod form; the novelty and interest of the cigarette filter rod are increased through a visual form, meanwhile, and the adsorption effect and the moist feeling of the filter rod on harmful substances of cigarette smoke are enhanced, therefore, the composition is easy to popularize and apply.

Description

technical field [0001] The invention belongs to the technical field of cigarettes, and in particular relates to a composition of thermoplastic starch, natural colloid and polymer, a preparation method thereof and an application in cigarette filter sticks. Background technique [0002] The development of the tobacco industry has been basically mature from tobacco leaf planting to cigarette production. Today, as the demands of the cigarette market become more and more diversified, internationalized and differentiated, consumers pay more attention to products with innovative visual design and enhanced functions. In the current tobacco industry (mainly in the field of cigarette production), nearly 80% to 90% of new inventions come from filter products. There is not much room for innovation in how the tobacco leaves are processed, and to what extent the outer wrapping paper or packaging might be improved. [0003] At present, the common forms of filter rods include core wire fi...

Problems solved by technology

[0004] In the patents of "A Slow-release Fragrance Filter Stick and Its Preparation Method" with application number "201610789606.7" and "Aroma Slow-release Material Composition and Slow-release Fragrance Colloid and Its Use" with application number "201710156063.X", Both are made of a mixture of polyethylene glycol polymers and natural colloid-binding additives to prepare cigarette filter rods. This method first aims to add the slow-release function of flavors, and the blend of materials has a very strong flow during processing. Poor plasticity, and can only exist in the form of natural irregularities. At the same time, because of its strong compactness, it has poor adsorption of harmful substances in mainstream cigarette smoke.
