Description
Technical Field
The invention belongs to the field of composite materials, and particularly relates to application of a moisturizing three-layer material to regulation and control of microenvironment humidity of cigars
Background
The cigar is produced, stored and sold, and finally, the cigar can be in the hand of the consumer for 1-2 years, and the temperature of 18-20 ℃ and the relative humidity of 65-70% are the most suitable conditions for preserving and maintaining the cigar. However, the environment outside the cigar undergoes different humidity and temperature variations, and the moisture content of the cigar will change dramatically if there is no effective moisture retention measure. Cigars with high water content are difficult to ignite and keep burning, and the smoking quality is also influenced; when the water content is low, even the eggplant clothes crack and other adverse phenomena can occur. Therefore, regulating the humidity of the cigar preservation microenvironment is of great significance in the transportation, storage and sale processes of cigars. Therefore, how to regulate and control the humidity of the cigar packaging microenvironment, maintain the sensory quality of cigar products and improve the market competitiveness of cigar storage is an important problem to be solved urgently.
Disclosure of Invention
The invention is based on hydrogel designed by special molecules containing moisturizing factors, a layer of hydrophobic elastomer with adjustable free volume is constructed on the surface of the hydrogel, and the efficient and safe cigar microenvironment humidity-regulating material is prepared by regulating the osmotic pressure of the hydrogel and the physical and chemical structure of the hydrophobic barrier elastomer, so that the controllable release and absorption bidirectional regulation function of the moisturizing material on water molecules is realized. According to different packaging materials of the cigar box, the humidity adjusting material suitable for cigar packaging microenvironment in different environments and different materials is prepared by regulating and controlling the formula and the process design. A feasible material production process and a feasible bonding process are obtained through exploration, the humidity regulating function of a cigar packaging microenvironment is finally realized, technical support is provided for the difficult problem of humidity control in the storage and transportation processes of cigars, and the market competitiveness of the cigar storage technology is improved. In addition, the developed intelligent humidity-regulating hydrogel can also be used for portable storage devices of cigars, and the storage form of cigar products is enriched.
The invention aims to provide application of a composite material with excellent humidity regulation performance to regulation and control of microenvironment humidity of cigars, and particularly adopts the following technical scheme:
use of a moisture retaining tri-layer material for the regulation of the humidity of a cigar microenvironment, said moisture retaining tri-layer material being disposed within a cigar preservation device; the moisturizing three-layer material is formed by chemically connecting an upper-layer elastomer, a middle-layer hydrogel and a lower-layer brush-shaped elastomer through a coupling agent;
the hydrogel is polyacrylamide hydrogel containing a moisturizing factor and a coupling agent, and the elastomer is brominated butyl rubber containing the coupling agent; the brush-shaped elastomer is an elastomer with brush-shaped polysiloxane as a matrix;
the polyacrylamide hydrogel is formed by polymerizing monomers under the action of an initiator, a catalyst and a cross-linking agent, and the monomers comprise acrylamide.
The cigar retention device includes, but is not limited to, a cigar pack.
The total thickness of the three layers of moisturizing materials is 1-50 mm, for example, the total thickness of the three layers of moisturizing materials can be 1mm, 5mm, 10mm, 15mm, 20mm, 25mm, 30mm, 35mm, 40mm, 45mm, 50mm and the thickness represented by any number in between. The total thickness of the moisture-keeping three-layer material is 1-50 mm, and the thickness ratio of the elastomer, the hydrogel and the brush-shaped elastomer is (0.2-10): (0.5-30): 0.2-10).

Experimental example 1 characterization of the Properties of the three-layer Material used according to the invention
1. Experimental methods
(1) Mechanical Property test
The tensile stress-strain behavior of examples 1 and comparative examples 1 to 2 (comparative example a, comparative example B) was tested with a universal tensile tester Instron 5567 at a tensile rate of 100mm/min, the samples were stretched until breaking and the stress-strain curves were recorded.
(2) Characterization of adhesive Properties
And (3) peeling the upper layer elastomer from the other two layers of materials, and observing the condition of the hydrogel remained on the surface of the peeled upper layer elastomer. In addition, to distinguish whether the three-layer material was crushed during the peeling process due to poor mechanical properties of the hydrogel, a uniaxial tensile test was performed on a bulk hydrogel having the same thickness as the hydrogel in the three-layer material, and the mechanical properties were evaluated.
(3) Test for moisture retention
The materials of example 1, comparative example 1 and comparative example 2 were weighed at 25 ℃ at different time points within 12 hours after saturation in water absorption, and the moisture retention rate was calculated according to the following formula to evaluate the moisture retention capacity of the materials:

in the formula: w is the moisture retention rate, m1Mass of sample saturated with water, m2Is the mass of the sample when weighed.
(4) Performance test for regulating and controlling humidity of cigar microenvironment by material
The moisturizing material obtained in example 1 was placed in a cigar pack, and a blank cigar pack without the moisturizing material was used as a control. The two groups of cigar boxes are respectively placed in the environment of 40% RH and 90% RH, and the change of the internal humidity of the cigar boxes along with time is monitored, so that the regulation and control effect of the material on the microenvironment humidity of the cigar is examined.
2. Results of the experiment
As can be seen from fig. 1, the humidity control material C of example 1 of the present invention has a three-layer structure, in which the upper and lower layers are the silicone elastomer layer and the brush-like elastomer layer, respectively, and function as a buffer barrier and control of water diffusion; the middle part is a hydrogel layer which has the functions of releasing and absorbing water.
As can be seen from FIG. 2a, after the upper layer elastomer of the three-layer material obtained in example 1 of the present invention was peeled from the other two layers, a large number of hydrogel fragments of the middle layer remained on the surface of the upper layer elastomer, indicating that good adhesion was formed between the elastomer and the hydrogel. In addition, the middle layer hydrogel was found to have good mechanical properties by tensile testing alone (fig. 2b), which demonstrates that the formation of hydrogel debris during peeling is not due to poor mechanical properties of the hydrogel itself, but rather due to good adhesion between the elastomer and the hydrogel.
From fig. 3, it can be found that the breaking strength and breaking strain of comparative example a of the two-layer structure formed of the brominated butyl rubber and the hydrogel are 0.84MPa and 430% respectively, and the breaking strength and breaking strain of comparative example B of the two-layer structure formed of the hydrogel and the brush elastomer are 0.43MPa and 240% respectively. The rupture strength and the rupture strain of the moisturizing three-layer material C in the embodiment 1 are respectively 1.53MPa and 825%, and are higher than the mechanical properties of the comparative examples A and B, even obviously higher than the sum of the mechanical properties of the comparative examples A and B, which shows that the mechanical properties of the bionic skin moisturizing material are improved by the composite cooperation of the brominated butyl rubber, the hydrogel and the brush-shaped elastomer three-layer material.
As can be seen from fig. 4, the moisturizing rate of the moisturizing three-layer material C of example 1 of the present invention was higher than the corresponding moisturizing rates of comparative examples 1(a) and 2(B) within 12 hours, indicating that the biomimetic skin moisturizing material of the three-layer structure had more excellent moisturizing performance than the brominated butyl rubber and hydrogel or hydrogel and brush-like elastomer of the two-layer structure.
As can be seen from fig. 5, after the cigar box is placed at 40 ℃ and 40% RH for 48 hours, the humidity inside the blank cigar box without the moisture retention material is reduced to below 60% RH, while the humidity control material C of the present invention can increase the humidity inside the cigar box to about 70% RH; after the cigar box is placed for 48 hours at the temperature of 40 ℃ and the RH of 90 percent, the internal humidity of the blank cigar box is increased to about 90 percent RH, and the humidity conditioning material C can control the internal humidity of the cigar box to about 80 percent RH. The above results show that the humidity control material of the present invention can control the release and absorption of moisture in the material according to the change of external humidity, so as to prevent the loss of moisture of the cigars in the low humidity environment and inhibit the absorption of moisture of the cigars in the high humidity environment, thereby reducing the influence of the external environment and maintaining the constant moisture content of the cigars.
