Description
Technical Field
The invention belongs to the technical field of heating non-combustion type cigarette filter rods, and particularly relates to a cooling section material of a composite filter rod for heating non-combustion type cigarettes.
Background
With the increasing severity of the global smoking control environment and the growing concern of consumers on health, the development of a novel tobacco product capable of comprehensively and greatly reducing the release amount of harmful components in tobacco gradually becomes the key point of the tobacco industry of all countries in the world. The cigarette without burning is a novel tobacco product which heats the cut tobacco by a special heat source (below 500 ℃ or even lower) and only heats the cut tobacco without burning. Researches show that the release amount of harmful components in tobacco smoke is closely related to heating and burning temperature, and the release amount of the harmful components in the smoke can be obviously reduced by reducing the heating or burning temperature.
The heating non-combustion type tobacco products are developed and researched by large international tobacco companies such as Philippi Morris production company (called Feimo for short) and R.J. Reynolds tobacco company (called Reynolds for short), and particularly, intellectual property layout is carried out on heating non-combustion type cigarette cigarettes. Chinese patents CN96194107.3, CN201190000997.0, CN201280018570.2, CN201280026033.2, CN201280054623.6, CN201280048973.1, CN201280054563.8, CN201180016009.6, CN 101778578A, CN 103889254 a, etc. applied by the company finmo tobacco; chinese patents CN201180031721.3 and CN200780045783.3, etc. applied by Reynolds tobacco corporation all disclose the cigarette technology of heating non-combustion type cigarette. In China, tobacco companies such as Yunan Zhongyan and Zhejiang Zhongyan also perform related intellectual property protection on the heating non-combustion type cigarettes (CN201710643438.5, CN201520442651.6, CN201710393624.8 and CN 201710391934.6).
However, market tests of the first two commercial electric heating type non-burning cigarette products (Accord, HeatBar) proposed by Felmo have not been successful so far, which further illustrates that the electric heating type non-burning cigarette products are still in the early growth stage at present, and still have many problems, wherein the problem particularly at the core is that the electric heating type non-burning cigarette has poor smoking feeling, which limits the market popularization to a certain extent, and the specific characteristics are as follows: high smoke temperature, poor smoke suction uniformity and the like.
At present, the research on heating non-combustion type cigarettes at home and abroad mainly focuses on cigarette devices, cigarette design, cigarette paper, heating modes, heater types and the like, and related documents and patent reports are few for materials at the cooling section in the cigarettes. Therefore, a material which can effectively reduce the temperature of smoke and is used in the composite filter rod is urgently needed.
Disclosure of Invention
The invention unexpectedly obtains a material capable of effectively reducing the smoke temperature, and the material can be used in a composite filter rod to effectively electrically heat the smoke temperature of a non-burning cigarette. Meanwhile, the material also has the advantages of selective adsorption, biodegradability and environmental friendliness.
The degradable cooling section material is prepared from a biodegradable polylactic acid raw material through a film obtained through a blow molding process, the thickness of the film is 0.01-0.06 mm, and the film is rolled and cut into a cylinder with the length of 8-10 mm and the diameter of 3-8 mm after embossing.
Preferably, the melt index of the biodegradable material polylactic acid raw material is 8.70-13.00.
Preferably, the blow molding process is: the temperature of the screw 1-4 area is 150 ℃, 175 ℃ and 170 ℃ in sequence, and the rotating speed of the screw is 100 pr/min.
Preferably, the thickness of the film is 0.02-0.05 mm
The invention has the beneficial effects that: the invention unexpectedly discovers that when the degradable temperature-reducing section material is selected to be made into a cylindrical rod body for heating a composite filter tip of a non-combustion type cigarette, the temperature-reducing amplitude can reach 50 percent to the maximum; the maximum cooling amplitude of the cylindrical rod body made of common polylactic acid is 27.9 percent. Meanwhile, the degradable cooling section material also has the advantages of biodegradability and environmental friendliness.

Detailed Description
Example 1
Selecting polylactic acid with the melt index of 8.70, preparing a polylactic acid-based film by adopting a blow molding film forming mode, adjusting the temperature of a screw rod 1-4 area to 150 ℃, 175 ℃ and 170 ℃ in sequence, adjusting the rotating speed of the screw rod to 100pr/min, and adjusting the traction speed of a film blowing auxiliary machine to prepare a smooth film with the thickness of about 0.04 mm. Embossing the film by an embossing machine, rolling into a rod body with the outer diameter of 5.7mm, cutting into a cooling section with the length of 10mm, and preparing into a heating non-combustion type cigarette. After passing the cooling test, the cooling amplitude reaches 44%.
Example 2
Selecting polylactic acid with a melt index of 13.00, preparing a polylactic acid-based film by adopting a blow molding film forming mode, adjusting the temperature of a screw rod 1-4 area to 150 ℃, 175 ℃ and 170 ℃ in sequence, adjusting the rotating speed of the screw rod to 100pr/min, adjusting the traction speed of a film blowing auxiliary machine, and preparing the smooth film with the thickness of about 0.03 mm. Embossing the film by an embossing machine, rolling into a rod body with the outer diameter of 5.2mm, cutting into cooling sections with the length of 8mm, and mixing to prepare the heating non-combustion type cigarette. After passing the cooling test, the cooling amplitude reaches 36%.
Example 3
Selecting polylactic acid with a melt index of 10.00, preparing a polylactic acid-based film by adopting a blow molding film forming mode, adjusting the temperature of a screw rod 1-4 area to 150 ℃, 175 ℃ and 170 ℃ in sequence, adjusting the rotating speed of the screw rod to 100pr/min, adjusting the traction speed of a film blowing auxiliary machine, and preparing the smooth film with the thickness of about 0.05 mm. Embossing the film by an embossing machine, rolling into a rod body with the outer diameter of 5.0mm, cutting into a cooling section with the length of 9mm, and preparing into the heating non-combustion type cigarette. After passing the cooling test, the cooling amplitude reaches 40%.
Example 4
A cooling section (control 1) made of a common cooling material such as a polyvinyl acetate fiber under the same conditions; a cooling section (control 2) made of a rod body prepared under the same conditions after polylactic acid with the melt index of not 8.70-13.00 is blown; the temperature of the zone in the film blowing conditions 1 to 4 was not 150 ℃, 175 ℃ and 170 ℃ and the temperature of the rod obtained under the same conditions after the film blowing at the screw rotation speed of not 100pr/min (comparative example 3) was compared with the temperature reduction range of the rod obtained in example 1 to 3, as shown in the following table.
| Cooling section | Extent of temperature reduction |
| Control 1 | 23.6％ |
| Control 2 | 27.9％ |
| Control 3 | 22.4％ |
| Example 1 | 44％ |
| Example 2 | 36％ |
| Example 3 | 40％ |
The cooling amplitude is defined as follows:
as can be seen from the table above, the polylactic acid with the melt index of 8.70-13.00 is selected, and the film obtained by blow molding is prepared into the cooling section material under the conditions that the temperature of the 4 zones is 150 ℃, 175 ℃ and 170 ℃ in sequence and the rotating speed of the screw is 100pr/min, and the cooling amplitude is obviously improved when the film is used for heating the composite filter rod of the non-combustion type cigarette. This effect is unexpected to those skilled in the art.
