Composite filter stick capable of selectively reducing releasing amount of harmful phenol in main stream smoke of cigarettes
A technology for mainstream cigarette smoke and composite filter rods, which is applied to e-liquid filter elements, tobacco, nanotechnology for material and surface science, etc., can solve problems such as reducing the amount of phenol released, and achieve low cost, coke reduction and harm reduction. The effect is obvious and the price is low

Embodiment 1
[0047] 60 parts by mass of polypropylene F401, 10 parts by mass of anhydrided polypropylene (maleic anhydride graft rate 0.5wt%), 20 parts by mass of organically modified sodium montmorillonite I.44P and 10 parts by mass of Nickel oxide is mixed at room temperature, and then added to the twin-screw extruder, and the polyolefin mixture is obtained after being melted and granulated; the polyolefin mixture is placed in a crucible, covered and placed in a 950°C muffle In the furnace, take it out after heating for 10 minutes, and cool it to room temperature in the air to obtain the carbon nanotube mixture.
[0048] The carbon nanotube mixture is used as a filter additive material, sieved to 100 mesh particles, and the particles are evenly distributed in the acetate fiber to obtain a carbon nanotube mixture / acetate fiber composite, and the carbon nanotube mixture / acetate fiber composite The carbon nanotube mixture was made into a composite filter rod with a length ratio of 1:1, and ...
Embodiment 2
[0051] Prepare a solution of ferric chloride, sodium silicate and zinc acetate at a molar ratio of 1.5:4.0:0.3, adjust the pH value to 11.2, put it in an autoclave and react at 160°C for 24 hours to obtain iron-based montmorillonite; Mix the above-prepared iron-based montmorillonite and octadecyltrimethylammonium bromide at a ratio of 1:2, add it to distilled water at a liquid-solid mass ratio of 80ml / g, and heat and stir at 100°C for 5h After centrifugation, it is washed with distilled water until it becomes neutral, and the organically modified iron-based montmorillonite is obtained after drying.
[0052] 90 parts by mass of polypropylene F401, 1 part by mass of anhydrided polypropylene (maleic anhydride graft rate 3wt%), 8 parts by mass of organically modified iron-based montmorillonite and 1 part by mass of iron oxide at room temperature Mix at low speed, then add to the twin-screw extruder, melt and granulate, and then discharge to obtain the polyolefin mixture; put the p...
Embodiment 3
[0056] 80 parts by mass of polyethylene 5000s, 5 parts by mass of anhydrided polyethylene (maleic anhydride graft rate 2.5wt%), 10 parts by mass of organically modified sodium montmorillonite I.31PS and 5 parts by mass of Cobalt hydroxide is mixed at room temperature, then added to a twin-screw extruder, and then fed into a polyolefin mixture after being melted and granulated; the polyolefin mixture is placed in a quartz tube, fed with nitrogen and oxygen according to the volume Mixed gas with a ratio of 9:1, put the quartz tube in a tube furnace at 750°C, take it out after heating for 20 minutes, and cool to room temperature to obtain a carbon nanotube mixture.
[0057] The carbon nanotube mixture is used as a filter tip additive material, sieved to 200 mesh particles, and the particles are uniformly distributed in the acetate fiber to obtain a carbon nanotube mixture / acetate fiber composite, and the carbon nanotube mixture / acetate fiber composite The carbon nanotube mixture ...
