Filter core, filter cigarette holder containing filter core and preparation method thereof

Abstract

The invention relates to the technical field of a cigarette filter and a preparation method of the cigarette filter, in particular to a filter element, a novel cigarette filter tip comprising the filter element and a preparation method of the novel cigarette filter tip. The filter element comprises components in percentage by weight as follows: 30-90% of plastic and 10-70% of a rare metal. The rare metal is evenly dispersed into the plastic, then the fluffy, curly, cylindrical or square filter element is prepared through the step, and the filter element has excellent contraction performance and can be mounted in a hollow case conveniently. When smoke of cigarettes passes through the filter element, the contact area is large, the permeability is high, the smoke can be fully contacted with the rare metal, the rare metal can effectively adsorb harmful substances such as nicotine and the like in the smoke, foreign smells of the cigarettes are reduced, the smell of the cigarettes is mellower and more abnormal, besides, the filtering effect is more durable, each cigarette filter tip can filter 20-40 cigarettes, the filter element can be replaced, the preparation method is simple in step, large-scale industrial production and application can be realized, and the product cost is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of a cigarette filter device and a preparation method thereof, in particular to a filter element, a filter cigarette holder containing the filter element and a preparation method thereof. Background technique [0002] With the increasing number of smokers around the world, various cigarette filter devices emerge in endlessly. The more common ones on the market are triple filter cigarette holders, which pass through plastic filter elements, silica gel filter beads and acetate fiber filter cotton in turn.
