example 1

[0028] Preparation of micro-carbonized fragrant wood powder:

[0029] Put the tobacco leaves into a pulverizer and pulverize 3 to obtain tobacco leaf powder. Put 200g of tobacco leaf powder and 250mL of water into a beater for beating for 2 hours to obtain tobacco leaf pulp. Sodium solution, heated up to 100°C, heat-preserved and cooked for 4 hours, filtered and separated to remove the filtrate to obtain delignified wood pulp;

[0030] Put the above-mentioned delignified wood pulp in a stirring tank, add 30 mL of aluminum chloride solution with a mass fraction of 5% to the stirring tank, start the stirrer, stir and mix at a speed of 200 r / min for 30 min, and then pour it at room temperature Aromatherapy gas is passed into the wood pulp at a ventilation rate of 30mL / min. The aromatization gas is a mixed gas of propylene and acetyl chloride with a volume ratio of 3:1. After aeration for 30 minutes, the stirring tank is sealed and stirred for 3 hours to obtain aromatization wood....

[0039] Preparation of micro-carbonized fragrant wood powder:

[0040] Put the tobacco leaves in a pulverizer for 3.5 hours to obtain tobacco leaf powder, put 210g of tobacco leaf powder and 270mL of water into a beater for beating for 3 hours to obtain tobacco leaf wood pulp, add 45mL of hydrogen with a mass fraction of 40% to the tobacco leaf wood pulp Sodium oxide solution, heated up to 105°C, heat-preserved and cooked for 4.5 hours, filtered and separated to remove the filtrate, to obtain delignified wood pulp;

[0041] Put the above-mentioned delignified wood pulp in a stirring tank, add 35 mL of aluminum chloride solution with a mass fraction of 5% to the stirring tank, start the stirrer, stir and mix at a speed of 230 r / min for 35 min, and then pour it at room temperature The aromatization gas is passed into the wood pulp at a ventilation rate of 35mL / min. The aromatization gas is a mixed gas of propylene and acetyl chloride with a volume ratio of 3:1. After ventilation ...

[0050] Preparation of micro-carbonized fragrant wood powder:

[0051] Put the tobacco leaves in a pulverizer for 4 hours to obtain tobacco leaf powder, put 220g of tobacco leaf powder and 300mL of water into a beater for beating for 3 hours to obtain tobacco leaf wood pulp, add 50mL of 40% hydrogen peroxide to the tobacco leaf wood pulp Sodium solution, heated up to 110°C, heat-preserved and cooked for 5 hours, filtered and separated to remove the filtrate to obtain delignified wood pulp;

[0052] The above-mentioned delignified wood pulp was placed in a stirring tank, 40 mL of aluminum chloride solution with a mass fraction of 5% was added to the stirring tank, the stirrer was started, and after stirring and mixing at a speed of 250 r / min for 40 min, it was poured at room temperature. Aromatherapy gas was introduced into the wood pulp at a ventilation rate of 40mL / min. The aromatization gas was a mixture of propylene and acetyl chloride with a volume ratio of 3:1. After aerat...

Abstract

The invention discloses a preparation method of a filter tip material, and belongs to the technical field of preparation of filter materials. Based on the principle that olefin and acid halide are subjected to a Friedel-Crafts reaction to generate corresponding [alpha],[beta]-unsaturated ketone, an aluminum chloride solution is dispersed in wood pulp, then mixed gas of propylene and acetyl chloride is introduced into the wood pulp to generate trans-3-pentene-2-ketone, which has a fruity flavor; and unsaturated ketones can react with hydroxyl groups in wood pulp fibers, so that the distance between the fibers and unsaturated ketone molecules is reduced, and the adsorption capacity of the filter tip material on wood offensive gas is enhanced. Roots and rhizomes of Platycodon grandiflorum andlicorice roots in the flavor enhancer can absorb nitrosamine gas in smoke and have the effects of relieving cough and reducing sputum. Sugar in corn flour and protein in egg white can be subjected toa Maillard reaction under a heating condition to generate aroma molecules. Agilawood powder can obviously cover cigarette offensive gas, so that the smoke is fine and mellow, and nitrosamine substances can be converted into nitrosamine salt to be adsorbed in the porous gel of the konjak. The product has a wide application prospect.

Description

technical field [0001] The invention discloses a method for preparing a 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. At present, the materials for preparing cigarette filters mainly include cellulose acetate fibers and polypropylene fibers. In addition to the properties of the material itself, the filter tip made of cellulose acetate fiber can also obtain a network structure with excellent properties such as filtration, blocking and adsorption through non-toxic adhesives, so it is generally used in high-end cigarettes . Although the cigarette filter made of cellulose acetate fiber has various excellent comprehensive properties, since cellulose acetate fiber is made of wood, it needs to undergo α-cellulose extraction, esterification, sapo...
