A kind of sepiolite antibacterial cigarette filter stick paper and its preparation method

Abstract

The invention discloses sepiolite antibacterial cigarette filter tip paper and a preparation method. According to the sepiolite antibacterial cigarette filter tip paper and the preparation method provided by the invention, [alpha]-sepiolite fibers, after being purified, are exposed to microwave radiation, and then the [alpha]-sepiolite fibers are subjected to potassium diformate loading modifyingtreatment, so that the adsorptivity and the antibacterial performance of the paper are improved, and when the [alpha]-sepiolite fibers are blended with plant fibers, OH+ active groups, metal cations and the like in [alpha]-sepiolite crystals can participate in an affinity effect with fibers having negative charges, which is beneficial for reserving the [alpha]-sepiolite fibers; meanwhile, flocculent three-dimensional structures, which are mutually interpenetrated, are constituted by rigid mineral crystal fibers and flexible wood fibers, so that the air permeability of the paper can be improved, and then coating liquid is applied to one side of the paper in one time, so that the prepared cigarette filter tip paper is high in tensile strength, high in breaking resistance and folding resistance and strong in adsorption capacity; the paper can take a selective adsorption effect on nitrile, acetone, acraldehyde and the like which can cause harm to human body health; and the paper is free from foreign smell, low in cost and free from influence to smoking taste.

Description

technical field [0001] The invention relates to the technical field of cigarette paper, in particular to a sepiolite antibacterial cigarette filter stick paper and a preparation method thereof. Background technique [0002] Smoking affects human health, and reducing harmful substances in cigarette smoke has always been a key research topic for tobacco scientists. Cigarette filters have evolved several times since their introduction in the 1920s and are now an important tool in altering tobacco tar and nicotine delivery. About 90% of the currently used filter filter materials are made of cellulose acetate, which mainly reduces the particulate matter in the smoke through mechanical filtration. While filtering out a large number of harmful components, there will still be considerable harmful components, especially extremely harmful components. Sexual compounds are inhaled into the human body, and the strength of cellulose acetate is low, and the cost of making filter materials...

Problems solved by technology

[0004] However, in the prior art, the combination between sepiolite fiber and plant fiber is difficult, and the strength of sepiolite fiber is low, and the obtained cigarette filter rod paper has poor anti-mildew and antibacterial properties, which not only reduces the service life of the filter rod paper but also endangers smoking. People who are healthy can easily cause respiratory diseases, cerebrovascular diseases, nasal cavity inflammation and other diseases
