Embodiment 1

[0021] Adjust the water content of the corn cob to 25%, then place it in a microwave expansion device, expand it under 1200w power for 60 seconds, spray the expanded corn cob with distilled water repeatedly to make the moisture content of the corn cob 25%, and store it at room temperature After standing for 6 hours, it was pulverized and sieved to obtain 50-mesh particles. Weigh 500g of the sieved particles and put them into 1kg copper chloride solution (concentration: 1%, pH: 3), stir evenly at the solution temperature of 60°C for 2h, cool to room temperature naturally, put the solvent-removed particles in In a microwave expansion device, dry for 30 seconds under the condition of a power of 600W, and place it at room temperature, and the desired modified corncob porous material is prepared.

Embodiment 2

[0023] Adjust the water content of the corn cob to 28%, then place it in a microwave expansion device, expand it for 90 seconds at a power of 1200w, spray the expanded corn cob with distilled water repeatedly to make the moisture content of the corn cob 25%, and store it at room temperature After standing for 10 hours, it was pulverized and sieved to obtain 80-mesh particles. Weigh 500 grams of copper chloride and 300 grams of zinc chloride and dissolve them in 10.2 kg of water and adjust the pH value of the solution to 2. Weigh 5 kg of sieved particles and put them into the mixed solution, and stir evenly at the solution temperature of 80 ° C for 2 hours , after naturally cooling to room temperature, the solvent-removed particles were placed in a microwave expansion device, dried for 60s under the condition of a power of 800W, and placed at room temperature, that is, the desired modified corncob porous material was prepared.

Embodiment 3

[0025] Adjust the water content of the corn cob to 20%, then place it in a microwave expansion device, expand it for 90 seconds at a power of 1500w, spray the expanded corn cob with distilled water repeatedly to make the moisture content of the corn cob 25%, and store it at room temperature After standing for 12 hours, it was pulverized and sieved to obtain 60-mesh particles. Take by weighing 500 grams of zinc sulfate, 800 grams of ferric chloride and 200 grams of copper chloride and dissolve them in 20.5kg of water, and adjust the pH value of the solution to 3, take by weighing 10kg of sieved particles and put them into the mixed solution. Stir evenly at 90°C for 2 hours, cool to room temperature naturally, place in a microwave expansion device, place the solvent-removed particles in a microwave expansion device, dry for 60 seconds under the condition of a power of 1000W, and place it at room temperature to prepare the obtained The desired modified corn cob porous material. ...

Abstract

The invention discloses a modified corncob porous material and application thereof to cigarettes. The porous material is obtained by performing procedures of microwave expansion, crushing granulation, modification with a modifier, microwave expansion drying and the like on corncobs. The modified corncob porous material is added to a cigarette filter to prepare a binary composite filter which is applied to the cigarettes, wherein the addition of the modified corncob porous material is 18 to 52 percent based on the total weight of the filter. Actual application shows that components such as tar, nicotine, hydrogen cyanide, phenol and crotonaldehyde in cigarette smoke can be effectively reduced. The modified corncob porous material is convenient to operate and low in cost, and has broad application prospect.

Description

technical field [0001] The invention belongs to the technical field of cigarette materials, and in particular relates to a porous material prepared by using corn cobs through chemical modification. At the same time, the invention also relates to the application of the porous material in cigarette processing. Background technique [0002] Corn is the main food crop in my country, and its total output and export volume both rank first in the world. The total annual output of corn in my country is about 150 million tons, and it can produce more than 20 million tons of corn cobs every year. Corncob, like wood, is a plant fiber raw material, mainly composed of 35% to 40% hemicellulose, 32% to 36% cellulose, 17% to 20% lignin and 1.2% to 1.8% ash. Moreover, the corn cob has uniform structure, appropriate hardness, good toughness, strong water absorption, and is easy to process. In addition to being partially used as raw materials for products such as furfural and xylitol, a larg...
