Hereinafter, the present invention will be described in more detail with reference to the following examples. The preparation and testing of paper using coffee powder, coffee extract, coffee extract-impregnated fly ash, etc. , Respectively.
1. Effect of coffee powder on rodent repellent effect
The present invention uses at least one coffee powder selected from the group consisting of coffee bean powder, roasted coffee bean powder, and coffee bean powder remaining after extracting coffee as a rodent repellent agent. The results are shown in Table 1.
Three groups of healthy male SPF ICR mice were divided into four groups and each group was placed in a cage. Feeds containing no rodent-repellent treatment and three kinds of coffee powder were placed in the cage, And the results are shown in Table 1. The results are shown in Table 1. < tb > < TABLE >
Fresh water was continuously supplied to the inside of the cage. In the feeding box, three mice were fed 900 g, which is enough to eat within 3 days. Among these, the three coffee powders were contained at about 15 wt%.
The amount of feed reduction was determined by subtracting the remaining weight after 3 days from the initial supply weight and expressed as a percentage.
The results of Table 1 show that the feed of Comparative Example 1, which is not treated with the repellent treatment, is reduced in all feeds, while the feed of the coffee powder according to the present invention is reduced by about 6 to 10% at about 3 days. Can be found. The best were roasted and non-roasted coffee bean powder, and the rest showed the same amount of feed reduction.
The reduction in feed was observed almost at the end of the test, and the first two days were almost water-free and did not go near the feeder, and the last day of the experiment, the hunger in the mouse was extremely severe, It can be seen that each of the depilatory extracts according to the present invention has a sufficient effect.
Then, three male SPF ICR mice were selected and classified into three groups. The mice were then injected into the cages of Examples 1 to 3 with a conventional mouse and then injected again after 3 days. After 900 g of the feed had completely disappeared And the results are shown in Table 2.
As shown in Table 2, in the case of Examples 1 and 3 of the present invention, the feeds completely disappeared on the last day of the tenth group, and in the case of Example 2, the feeds disappeared completely on the last day of the 15th group.
This study examined the duration of the avoidance effect of coffee powder on the coffee powder and found that it persisted for a considerable period of time. In this test, it was tested in an extreme condition where only water can be eaten. In the natural state of being able to sustain the evasion effect for a considerable period of time.
2. Containing coffee extract
Of fly ash
Rodent repellent effect test
(1) Containing coffee extract Fly ash Produce
Two coffee extracts were prepared. The first is the methanol extract of the roasted coffee beans, and the next is the roasted coffee beans extracted with methanol.
Various methods such as a method in which methanol is dipped for a long time and a method for reflux extraction have already been known. In this embodiment, 75% methanol was used for reflux extraction, and the extraction target was extracted with 75% methanol and a weight ratio of 1: . These extracts are stored under reduced pressure and the concentration is adjusted as necessary.
(2) Containing coffee extract Of fly ash Produce
The coffee extract-containing fly ash was prepared by mixing the fly ash with the coffee extract, impregnating the fly ash with the coffee extract, and drying the impregnated material.
The coffee extract, which had been concentrated under reduced pressure, was re-dispersed in methanol to be sufficiently impregnated in fly ash. When the coffee extract was concentrated under reduced pressure, the residue was dispersed in methanol using methanol having a concentration of 1 to 2 times .
Subsequently, the fly ash is mixed with the coffee extract to impregnate the fly ash with the coffee extract.
The fly ash of the present invention is a waste generated in the pulverized coal combustion process of a coal-fired power plant, and since most of the waste is composed of porous silica, the effect of avoiding rodents is continuously maintained, and the effect of paper strength is increased.
Particularly, it is preferable to use the refined fly ash as the refined fly ash so as to have a uniform particle size. The size of the particles is not particularly limited, but it is preferable to use fly ash having an average particle size of 20 to 30 micrometers ..
In addition, the mixing of the fly ash and the coffee extract may be carried out by stirring at room temperature for 6 hours to 8 hours. The stirring may be performed in an agitator, but is not limited thereto.
Subsequent filtration of the fly ash is followed by drying to complete the preparation.
(3) Fly ash effect test containing coffee extract
The fly ash prepared as described above was used in an effect test, wherein the fly ash is a refined fly ash of 20 microns.
To test the effect, three healthy male SPF ICR mice were divided into four groups, each group was placed in a cage, a box containing a mixture of the feed inside the cage and the rodent attractant was put in the box, The fly ashes of the impregnated examples 1 and 2 prepared above were sprayed so as to be 1 cm long, and the state of the box was observed three days after the spraying. The results are shown in Table 3. Fresh water was continuously supplied to the inside of the cage, and a cage not sprayed with fly ash was used as a control.
As shown in Table 3, in the case of the control group, the box was damaged and 100% of the inner feed was consumed. However, in the case of the impregnation example 2 according to the present invention, the container was not damaged at all. That is, In the case of impregnated example 1, it was found that there was a small amount of remnants left after attempting to deteriorate the impregnation.
Subsequently, three male SPF ICR mice were selected and classified into two groups. After the mice were replaced with the existing mice in the cages of Examples 1 and 2, the mice were injected again after 3 days, and the box was damaged. The number of days of decrease was counted from the first test, and the results are shown in Table 4.
As shown in Table 4, in the case of the impregnation example 1 of the present invention, box damage and internal feed reduction started to appear on the last day of the tenth group, and in the case of the impregnation example 2, And damage to boxes and internal feed reduction began to appear.
This test was conducted to determine the duration of the avoidance effect and it was confirmed that it lasted for a considerable period of time. In this test, the test was conducted in an extreme condition where only water can be eaten, and the natural state It is possible to continue the avoidance effect for a considerable period of time.
3. Paper manufacturing and testing including coffee powder
(1) Manufacture of paper
In this embodiment, paper is prepared using high-fat pulp, and the process is described. High-fat pulp is separately mixed and dissociated into three types of coffee powder, i.e., green bean powder, roasted powder, and after-extract powder.
At this time, if the particle size of the coffee powder is too large or the amount of the coffee powder mixed is too small, the coffee powder is pulverized to a particle size of 150 to 200 mesh / inch, 25 to 100 parts by weight, based on 100 parts by weight of the total amount of the composition.
Next, the mixed and dissociated pulp is mixed with a refiner to mix various additives such as a sizing agent, a strength enhancer, a retaining agent, a defoamer, and a dye to provide various properties, If the amount is too large, the cost increases unnecessarily. If the amount is too small, the desired characteristics can not be obtained. Therefore, the amount is preferably within a range of 0.1 to 2 parts by weight based on 100 parts by weight of the dry weight of the pulp. Antifoaming agents, dyes, and the like can be used without any particular limitation as long as they are well known in the art to which the present invention belongs.
Then, the pulp was uniformly removed, the foreign matter was removed, and the paper was papermaking in the form of paper, squeezed, dewatered and dried, and then the paper was made uniform in thickness and cut into sheets or rolls to produce paper.
(2) Measuring the strength of paper
The results are shown in Table 5. The results are shown in Table 5. The results are shown in Table 5. The results are shown in Table 5. The results are shown in Table 5. In the comparative example, paper made only of high-grade pulp without using the coffee powder was used.
The paper strength is determined mainly by the bond strength between fibers and the strength of the fiber itself, which is an important index for determining resistance and durability against physical forces, and thus is a very important factor in the quality of paper such as the present invention. Thus, the properties of the paper according to the Examples and Comparative Examples were evaluated in terms of strength with respect to TAPPI Stasdard T200 om-83, TAPPI Stasdard T494 om-81, TAPPI Stasdard T403 om-85, TAPPI Stasdard T414 om-82, TAPPI Stasdard T511 om-83.
(kPa · m2 / g)
Tensile strength is one of the most important strengths related to durability. In the present invention, in order to show the tensile strength corrected to a basis weight, the tensile strength is denoted as the heat capacity. The tensile strength of the MD / CD was improved as compared with the paper of the comparative example, as shown in Table 5, because the use of the coffee powder is considered to be due to the increase of the bonding force between the fiber and the fiber. In addition, the tear strength and tear strength were also higher in the raw paper according to the present invention than in the comparative example.
(3) avoidance of rodents in box
The box was made using the paper, then a mixture of rodent feed and inducer was put into the box, and the paper box was stored in a warehouse together with other rodents feed and attractant. The paper using the paper according to the present invention showed no damage even for 50 days measured in all of the paper examples 1 to 3.
4. Contains coffee powder and coffee extract Fly ash Including paper making and testing
This embodiment is similar to the process for producing the paper including the three kinds of coffee powder except that the fly ash impregnated with the coffee extract extracted from the roasted beans is further contained, Preferably 25 to 100 parts by weight, based on 100 parts by weight of the resin composition, and 30 parts by weight in the present embodiment.
The fly ash used was a refined fly ash having an average particle size of 20 to 30 micrometers.
(Fly ash impregnated with green bean powder + coffee extract), Example 5 (fly ash impregnated with roasting bean powder + coffee extract), Example 6 (ground powder after extraction, The fly ash impregnated with the coffee extract) was measured. The results are shown in Table 6. < tb > < TABLE > In the comparative example, paper made only of high-grade pulp was used.
The paper strength is determined mainly by the bond strength between fibers and the strength of the fiber itself, which is an important index for determining resistance and durability against physical forces, and thus is a very important factor in the quality of paper such as the present invention. Thus, the properties of the paper according to the Examples and Comparative Examples were evaluated in terms of strength with respect to TAPPI Stasdard T200 om-83, TAPPI Stasdard T494 om-81, TAPPI Stasdard T403 om-85, TAPPI Stasdard T414 om-82, TAPPI Stasdard T511 om-83.
(kPa · m2 / g)
It can be seen from Table 6 that the improvement is more improved than the Comparative Example made only with the high-fat pulp, and the improvement is more improved than the Examples 1 to 3 containing only the coffee powder.
(3) avoidance of rodents in box
The box was made using the paper, then a mixture of rodent feed and inducer was put into the box, and the paper box was stored in a warehouse together with other rodents feed and attractant. The paper using the paper according to the present invention showed no damage even on the 80th day of the measurement in all of the paper examples 4 to 5.
As described above, it can be confirmed that the paper produced according to the present invention has excellent advantages such as an increase in strength and a persistent avoidance of rodents.
The above-described embodiments are provided for the purpose of facilitating understanding of the present invention, and are not intended to limit the scope of the present invention.
