Embodiment 1

[0014] Take by weighing 100g of pigment, 300g of combustion enhancer and 200g of spice substance, mix it and be mixed with 6000ml of 10% mixed solution, stir evenly to prepare microcapsule core material, add microcapsule core material to the mixture made of ethyl cellulose and hydroxypropyl cellulose Base cellulose in 3000ml mixed solution with a concentration of 3% mixed at a mass ratio of 1:1, use a high-speed disperser at 800r / min, keep the temperature at 40°C, and continue emulsifying for 30min to form a uniform emulsion. Use 20% acetic acid solution to adjust the pH value of the system to 4.0, reduce the stirring speed to 300rpm to make the wall material coagulate, and keep the temperature for 5 minutes. Cool the above coagulation system to 10°C, adjust the pH to 5.5 with 10% sodium hydroxide solution, add 4.5 g of transglutaminase, and keep stirring at a low speed of 100 rpm to solidify the microcapsules to obtain coating liquid microcapsules. Apply the microcapsules of ...

Embodiment 2

[0016] Take by weighing 200g of pigment, 150g of combustion enhancer and 100g of fragrance substance, mix it with 4500ml of 10% mixed solution, stir evenly to prepare microcapsule core material, add microcapsule core material to ethyl cellulose and hydroxypropyl cellulose In 1500ml of mixed liquid with a concentration of 2% mixed with cellulose-based cellulose at a mass ratio of 1:2, use a high-speed disperser at 1500r / min, keep the temperature at 45°C, and continue emulsifying for 20 minutes to form a uniform emulsion. Use 20% acetic acid solution to adjust the pH value of the system to 3.0, reduce the stirring speed to 500rpm to make the wall material coagulate, and keep the temperature constant for 10 minutes. Cool the coagulation system above to 15°C, adjust the pH to 6.0 with 10% sodium hydroxide solution, add 3.6 g of transglutaminase, and keep stirring at a low speed of 150 rpm to solidify the microcapsules to obtain coating liquid microcapsules. Apply the microcapsules...

Embodiment 3

[0018] Take by weighing 400g of pigment, 200g of combustion enhancer and 500g of fragrance substance, mix them to make 11000ml of 10% mixed solution, stir evenly to prepare microcapsule core material, add microcapsule core material to the mixture made of β-cyclodextrin and poly Vinyl alcohol mixed with 1:3 mass ratio in 2750ml of mixed solution with a concentration of 2%, use a high-speed disperser at 3000r / min, keep the temperature at 45°C, and continue to emulsify for 10min to form a uniform emulsion. Use 20% acetic acid solution to adjust the pH value of the system to 5.0 to make the wall material coagulate, and keep the temperature constant for 8 minutes. Cool the above coagulation system to 15°C, adjust the pH to 6.5 with 10% sodium hydroxide solution, add 13.7 g of transglutaminase, and keep stirring at a low speed of 200 rpm to solidify the microcapsules to obtain coating liquid microcapsules. Apply the microcapsules of the coating solution to the reconstituted tobacco ...

Abstract

The invention relates to a method for preparing colorful recombined tobacco leaf paper by microencapsulation of coating liquid. According to the method, substances such as pigments, a combustion improver and spices in the coating liquid are wrapped by a microencapsulation technology to prepare a core material, ethyl cellulose, hydroxypropyl cellulose and the like are adopted as wall materials, a complex coacervation method is adopted for preparing coating liquid microcapsules, and the coating liquid microcapsules are applied to recombined tobacco leaf paper in an airblade coating way to prepare the colorful recombined tobacco leaf paper. The colorful recombined tobacco leaf paper is good in color-fixing capability and free from fading, has slow-releasing and fragrance-keeping effects, and can be effectively improved in appearance quality and smoking quality.

Description

technical field [0001] The invention relates to the field of cigarette auxiliary materials, in particular to a method for preparing colored recombined tobacco leaf cigarette paper by microencapsulating coating liquid. Background technique [0002] Cigarette paper is a special type of paper that occupies a place in the tobacco packaging industry. The cigarette paper used in daily packaging is made of bleached whole wood pulp fibers, which can wrap tobacco and provide visual effects. Colored cigarette paper is a new product that has appeared at home and abroad in recent years, and has been loved by more and more smokers. Chinese patent CN101886355B discloses a method for preparing colored cigarette paper by using natural tobacco extract and food coloring as the raw material basis for double-sided sizing and dyeing by dip coating; Chinese patent CN102409577A discloses a method that uses different The dyeing agent is formulated into a coating solution, and the coating solution ...
