Example Embodiment

[0020] Example 1

[0021] Pour oxalic acid, citric acid and water into a beaker according to the mass ratio of 3:1:20, stir and dissolve with a glass rod for 30 minutes to obtain an organic acid solution; after the sepiolite is ball milled, pass through a 500-mesh sieve, and pass the sieve After mixing the sepiolite and the organic acid solution at a mass ratio of 1:20, ultrasonically immerse for 3h at an ultrasonic frequency of 55kHz and a temperature of 55℃ to obtain an impregnating solution, and transfer the obtained impregnating solution to the rotary evaporator. At a temperature of 75°C and a pressure of 600kPa, under reduced pressure and concentration for 5 hours, the No. 1 concentrate is obtained. The obtained No. 1 concentrate is dried at a temperature of 95°C for 4 hours and then transferred to a tube furnace. Under the condition of 400℃, heat preservation and roasting for 60min, cooling to room temperature with the furnace, and discharging to obtain pretreated sepiolite...

Abstract

The invention discloses a preparation method of a composite aerogel type cigarette filter material, belonging to the technical field of preparation of filter materials. The preparation method comprises the following steps: mixing sepiolite with an organic acid solution, carrying out ultrasonic immersing, carrying out concentration under reduced pressure, carrying out drying, carrying out roasting,thus obtaining pretreated sepiolite, enabling the pretreated sepiolite to react with organic alkali, carrying out concentration under reduced pressure, carrying out drying, thus obtaining modified sepiolite, adding carbomer, phospholipid and carrageenan into water, carrying out ultrasonic dispersion, adding glycoprotein, carrying out constant-temperature stirring reaction, thus obtaining a mixedsolution, stirring the modified sepiolite and the mixed solution at constant temperature, injecting the obtained mixture into a mold, carrying out low-temperature precooling, carrying out vacuum freeze drying, and carrying out demolding, thus obtaining the composite aerogel type cigarette filter material. The composite aerogel type cigarette filter material prepared according to the technical scheme provided by the invention has the excellent adsorption property, has the obvious adsorbing effect for hazardous substances in cigarettes, has good mechanical property, and can reserve the fragranceof the cigarettes.

Description

technical field [0001] The invention discloses a preparation method of a composite airgel type cigarette filter tip material, which belongs to the technical field of filter material preparation. Background technique [0002] Cigarette filters were originally designed to prevent cigarette paper from sticking to the lips and prevent tobacco from being sucked into the mouth during smoking. However, after the researchers released the epidemiological research results on the harmfulness of smoking to health, consumers' recognition of the appearance of the end face of the acetate filter tip and the effect of tar reduction led to a sharp increase in the market share of the acetate filter tip, and the filter tip became an indispensable part of cigarettes. . As society pays more and more attention to smoking and health issues, researchers in the tobacco industry have carried out a lot of research in the fields of filter material modification and development, filter parameter optimiza...
