Description
Technical Field
The invention relates to the technical field of packaging materials for cigarettes, in particular to a preparation method of a carton material for cigarettes.
Background
China is used as a large country for tobacco planting, and the annual yield of tobacco is the first place in the world, but about millions of tons of waste tobacco leftovers are wasted because the waste leftovers cannot be used for preparing tobacco, wherein the tobacco stems are the main. Tobacco stems are coarse hard midribs in tobacco leaves, and account for about 25-30% of the weight of the tobacco leaves. At present, the tobacco stems are mainly utilized: preparing a coating and plastic product; chemical raw materials and chemical fertilizer raw materials are obtained from tobacco stems or the tobacco stems are used for preparing activated carbon; extracting nicotine from tobacco stalk material to prepare pesticide and bactericide.
In the early stage, most of traditional smoke boxes are prepared by taking wood plates as raw materials, but along with the continuous rising of the price of the wood and the gradual enhancement of the environmental protection consciousness of consumers, the requirements of manufacturers on cost and the requirements of great trends on environmental protection are gradually difficult to meet by the wood plate smoke boxes. The tobacco stems are used as raw materials for preparing the tobacco boxes, so that not only can the resource waste be avoided, but also the effects of reducing the cost, being biodegradable and reducing the environmental pollution can be achieved. However, as the tobacco stems have certain hydrophilicity, the energy consumption requirement is increased in the mechanical pulping or chemical pulping process, and the tobacco stems are difficult to be directly applied to papermaking paper.
Therefore, how to provide a preparation method of a carton material for cigarettes, which has simple process, low cost and good biodegradability, becomes a problem to be solved by the technicians in the field.
Disclosure of Invention
In order to solve the technical problems, the invention provides the preparation method of the cigarette packaging material, which takes the tobacco stems as raw materials, not only meets the national 'low-carbon economy' requirement, but also further enriches the raw material warehouse of the cigarette carton material, not only can avoid resource waste, but also can achieve the effects of reducing cost, biodegradability and environmental pollution.
The invention provides a preparation method of a carton material for cigarettes, which comprises the following steps:
S1, putting a tobacco stalk raw material into a bionic enzyme solution for pretreatment to obtain first slurry;
S2, performing first sterilization treatment on the first slurry to obtain second slurry;
S3, adding white rot fungi into the second slurry for treatment to obtain a third slurry;
S4, performing second sterilization treatment on the third slurry to obtain papermaking slurry.
At present, tobacco stems are generally discarded as leftover materials, so that not only is natural resources wasted, but also environmental pollution is generated. Researches show that lignin with smaller molecular weight in tobacco stems is mostly hydrophilic, and the lignin has the defect that the energy consumption is increased in the mechanical pulping or chemical pulping process, so that the lignin is difficult to directly apply to paper making, and therefore, the lignin must be treated before pulping to remove the lignin.
According to the invention, tobacco stems are used as raw materials, the tobacco stems are subjected to bionic enzyme treatment and then subjected to white rot fungi treatment, lignin in the tobacco stems is removed, and the slurry with high cellulose content is obtained and used for manufacturing paper and paper box materials for cigarettes.
The bionic enzyme is a substance which is synthesized by a chemical method and has the same effect after components which play a leading role are screened out from natural biological enzymes. The substance has the characteristics of specificity and high efficiency of enzyme, simple chemical substance structure and stable property. Under specific culture conditions, the substrate is used as a catalyst to identify, combine and catalyze.
White rot fungi have a set of unique enzymatic degradation systems, including lignin peroxidase, manganese peroxidase, laccase. The white rot fungus degrading lignin mainly comprises two stages: ① In cells, white rot fungi are stimulated by external conditions, and intracellular metabolism synthesizes various lignin-degrading enzyme systems, including an H 2O2 -producing enzyme system and a lignin-degrading enzyme system. ② In the extracellular, the catalytic function of lignin degrading enzyme plays a role in catalyzing lignin with high efficiency, the catalytic product and the existing components thereof generate H 2O2, a series of free radical chain reactions are triggered, and after the enzyme intermediate with high reactivity is generated, lignin is oxidized into a plurality of different free radicals, and finally, the lignin is degraded into CO 2 and H 2 O.
Preferably, in step S1, the bionic enzyme in the bionic enzyme solution comprises the following raw materials in parts by weight: 45-55 parts of magnesium sulfate, 25-30 parts of ferrous nitrate, 20-25 parts of sodium carboxylate and 25-30 parts of potassium carboxylate.
In the biomimetic enzyme treatment process, mgSO 4、Fe(NO3)2 is added with water to be dissolved to generate Fe 3+、Mg2+, and under the influence of aspartic acid and cysteine in the tobacco stems, the Fe-Mg dimeric metalloenzyme is formed. Under the action of the iron-magnesium dimerization metalloenzyme, lignin pectin which is originally combined between fibers is removed, a bridging connection of water molecules, iron-magnesium dimerization metalloenzyme and water molecules is formed between the fibers, fe 3+、Mg2+ is positioned at the C end of triose isomerase and is connected by a hydroxyl group serving as a bridge, along with the reduction of temperature and the reduction of substrates (lignin and pectic substances), the enzymatic reaction speed is reduced, the iron-magnesium dimerization metalloenzyme is removed from the bridging connection, the connection of two water molecules is unstable, one water molecule is removed, and a water bridge connection is formed between the fibers. The connection between fibers is facilitated by the treatment of the bionic enzyme, and the physical strength of the finished paper is improved.
Preferably, the concentration of the bionic enzyme in the bionic enzyme solution is 0.6mol/L-0.85mol/L.
Preferably, the mass ratio of the tobacco stalk raw material to the bionic enzyme solution is 4:1-5:1.
Preferably, in step S1, the temperature of the pretreatment process is 25-35 ℃ and the time is 4-6h.
Preferably, in step S1, aeration is maintained while maintaining the temperature.
Preferably, in step S1, the pretreatment process is performed for 4.5-5.5 hours.
Preferably, in step S1, the aeration treatment is to reflux the liquid by a water pump.
Preferably, in the step S1, the liquid is pumped out by a water pump and then flows back to the reaction system, so that on one hand, materials can be mixed more uniformly, and the reaction is more complete; on the other hand, air is mixed while the reaction system is refluxed, so that the oxygen in the reaction system is ensured to be sufficient, and the reaction is facilitated.
Preferably, in the step S3, the addition amount of the white rot fungi is 2-3% of the mass of the second slurry.
Preferably, in the step S3, the addition amount of the white rot fungi is 2.2% -2.8% of the mass of the second slurry.
Through researches, in the process of degrading lignin by white rot fungi, firstly, long-bond hydrocarbon with large molecular weight is cut off to generate short-bond hydrocarbon with small molecular weight, a cyclic structure is opened, the lignin is cracked to form chain compounds, the number of hydroxyl groups, methylene groups and carboxyl groups is continuously increased, and lignin is degraded into micromolecular acids or lipids to be further utilized by the growth and metabolism process of the white rot fungi.
Preferably, in the step S3, phosphate buffer solution with pH value of 7.2-7.4 is added in addition to white rot fungi, and the adding amount of the phosphate buffer solution is 20-30% of the mass of the second slurry.
