(The problem to be solved by the invention)

Here, the heat-insulating and sound-absorbing material generally uses ^{glass wool with a density of 24 kg/m 3} and a thickness of 50 mm. In response to this, in recent years, the construction workers of the partition walls are becoming short of staff and aging. Generally, the heat insulation and sound-absorbing materials used are heavy, which will cause a large burden on the operation for the elderly and unskilled workers. By reducing the density of the heat-insulating and sound-absorbing material, the weight can be reduced and the workability can be improved. However, if the density is only reduced, the sound insulation performance will decrease.

The present invention was completed in view of the above-mentioned problems, and its object is to provide a heat-insulating and sound-absorbing material that suppresses the reduction in sound insulation performance and improves workability, and a partition wall containing the heat-insulating and sound-absorbing material. (Technical means to solve the problem)

If the density of the heat-insulating and sound-absorbing material is reduced, the weight of the heat-insulating and sound-absorbing material is reduced, so the workability is improved. However, if the density of the heat-insulating and sound-absorbing material is lowered, the sound-insulating performance is lowered.

Furthermore, if the fiber diameter of the inorganic fiber of the heat-insulating and sound-absorbing material is reduced, it is possible to suppress the deterioration of the sound insulation performance due to the reduced density. However, if the fiber diameter of the inorganic fiber of the heat-insulating and sound-absorbing material is reduced, the hardness of the heat-insulating and sound-absorbing material is reduced, and the workability is lowered.

In contrast, the inventors found that by improving the fiber diameter distribution of the inorganic fibers constituting the heat-insulating and sound-absorbing material, the decrease in sound insulation performance can be suppressed, and the workability can also be improved.

According to an aspect of the present invention, a heat-insulating and sound-absorbing material composed of an inorganic fiber block, wherein the density of the block is 10-20 kg/m ³ , and the length-loading average fiber diameter of the block inorganic fiber is 2.0-8.7 μm; The block system contains 20-66% of inorganic fibers with a length-loaded average fiber diameter of less than 4.0μm, and 13-58% of inorganic fibers with a length-loaded average fiber diameter of 7.0μm or more. In addition, the total of inorganic fibers of less than 4.0 μm, inorganic fibers of 4.0 μm or more and less than 7.0 μm, and inorganic fibers of 7.0 μm or more is 100%. Here, the proportion of inorganic fibers in the range of the average fiber diameter of each length load in the present invention represents the count ratio (count %). According to the above configuration, because the heat and sound absorbing material is light in weight, workability can be improved, and the heat and sound absorbing material has constructional hardness, which can improve workability and can ensure sufficient sound insulation performance.

Preferably, the block system is formed into a plate shape with the first layer and the second layer laminated, and the length-loaded average fiber diameter of the inorganic fibers of the first layer is 0.1 to 3.0 μm larger than the length-loaded average fiber diameter of the second layer of inorganic fibers.

(Compared to the effect of the previous technology)

According to the present invention, it is possible to provide a heat-insulating and sound-absorbing material that improves workability without degrading sound insulation performance, and a partition wall containing the heat-insulating and sound-absorbing material.

Hereinafter, embodiments of the heat insulating and sound absorbing material and partition walls of the present invention will be described with reference to the drawings. <The first embodiment> Fig. 1 shows a cross-sectional view of a heat-insulating and sound-absorbing material according to the first embodiment of the present invention. As shown in Fig. 1, the heat-insulating and sound-absorbing material 1 of the first embodiment has a single-layer structure, and is composed of a plate-like block in which inorganic fibers are block-blocked with a binder. When used in a partition wall, the thickness of the heat-insulating and sound-absorbing material 1 is preferably 10-100 mm.

(Method of manufacturing heat-insulating and sound-absorbing material) First, the glass wool can be manufactured by liquefying the glass melt in a glass melting furnace, and then extracting a predetermined amount of glass, using a fiberizing device, heating by combustion of gas and air, and stretching the fiber with compressed air. The method of fibrillation can be exemplified by the conventionally known centrifugal method, flame method, air jet method, etc., but it is not particularly limited to these methods. Examples of the fiberization device performed by the centrifugal method may be, for example, a spinning machine.

The heat-insulating and sound-absorbing material 1 can be manufactured by piling up glass wool to form a blanket. Specifically, a predetermined amount of binder containing any dustproof agent or other additives is blown to the glass wool, and then the laminated conveyor belt is used to collect the cotton according to the established basis weight, and then the binder is hardened by the oven. Then, cutting pile (slitting), trimming cutting, short-side cutting of the product, etc. are performed, and the molding is performed in a manner to become a glass wool carpet of a predetermined size.

(Density of the heat-insulating and sound-absorbing material) The block density of the heat-insulating and sound-absorbing material in this embodiment is 10-20 kg/m ³ . The bulk density can be measured in accordance with the method of JIS A9521, for example.

When the block density is less than 10 kg/m ³ , the sound insulation performance of the heat-insulating and sound-absorbing material is insufficient, and the heat-insulating and sound-absorbing material 1 may bend or sag during construction, resulting in difficulty in construction.

Furthermore, when the block density is greater than 20 kg/m ³ , the weight of the heat-insulating and sound-absorbing material 1 is too large, which causes a load on the construction during the loading and installation work, and makes the work of the elderly or unskilled workers difficult. In addition, because the construction weight per unit area increases, the transportation efficiency decreases. In addition, cutting when cutting the heat-insulating and sound-absorbing material 1 into a predetermined shape tends to be difficult. In addition, if the density of the bulk is too high, the manufacturing cost will increase.

In contrast, in the present embodiment, the block density is 10-20 kg/m ³ , which can ensure sufficient sound insulation performance, and the heat-insulating and sound-absorbing material 1 has constructional rigidity, and because it is lightweight, workability is improved. In addition, the construction weight per unit area is also small, and the transportation efficiency can also be improved. In addition, the heat-insulating and sound-absorbing material 1 can be easily cut into a predetermined shape, and the manufacturing cost can also be reduced.

(Inorganic fiber length load average fiber diameter) In this embodiment, the length and load average fiber diameter of the inorganic fibers constituting the block of the heat-insulating and sound-absorbing material is 2.0 to 8.7 μm. In this embodiment, the measurement of the length-load-average fiber diameter of the inorganic fibers is performed using cottonscope HD manufactured by Cottonscope Pty Ltd, and the measurement conditions are as follows. The length-load-average fiber diameter system uses a microscope to magnify the fibers dispersed in water, and then reads the images taken by the camera into a computer, uses image processing to measure the fiber diameter, and obtains the average value from the measured values of 30,000 fibers. However, fibers with a length of 50 μm or less and fibers with a length shorter than 3 times the fiber diameter or less are excluded from the statistics. In addition, in order to implement statistics considering the fiber length, long fibers with a length greater than 50 μm are automatically divided into lengths by image processing, and then the values obtained by measuring the divided fiber diameters are respectively counted.

[Table 1] Measurement conditions Calibration Selection Use LWD Yes Width calculation Arithmetic mean Remove glass bundle No diam slope 2.6355 diam ofs -2.8029 Minimum width(μm) 0.00 Maximum width(μm) 65.00 Minimum fibre length(mm) 0.05 Minimum length-width ratio 3 Maximum Focus 10 Maximum density of sample 8 Minimum length confidence 0.9 Minimum span 2 Min width(μm) on graph 0.0 Max width(μm) on graph 30.0 Fibre limit 30000 Device name: cottonscopeHD Manufacturer: Cottonscope Pty Ltd

If the length-load-average fiber diameter of the inorganic fibers is less than 2.0 μm, the rigidity of the heat-insulating and sound-absorbing material 1 is low, which may bend or sag during construction, resulting in difficulty in construction. In addition, if the length-loaded average fiber diameter of the inorganic fibers is greater than 8.7 μm, the voids will increase, resulting in a decrease in sound insulation performance. In contrast, in this embodiment, since the length-loaded average fiber diameter of the bulk inorganic fiber is 2.0 to 8.7 μm, the rigidity (hardness) of the heat and sound absorbing material 1 is improved, workability can be improved, and sufficient sound insulation performance can be ensured.

Furthermore, it is more preferable that the length-load average fiber diameter of the bulk inorganic fiber constituting the heat-insulating and sound-absorbing material of this embodiment is 3.8 to 5.3 μm. In addition, the fiber length is preferably 20 mm to 200 mm. The longer the fiber length, the easier it is to increase the rigidity. Thereby, the heat-insulating and sound-absorbing material 1 can maintain sufficient rigidity, and can further improve workability and sound insulation performance.

(Inorganic fiber length and load fiber diameter distribution) The block system constituting the heat-insulating and sound-absorbing material of this embodiment contains 20 to 66% of inorganic fibers having a length-loaded average fiber diameter of less than 4.0 μm, and 13 to 58% of inorganic fibers having a length-loaded average fiber diameter of 7.0 μm or more. In addition, the total of inorganic fibers of less than 4.0 μm, inorganic fibers of 4.0 μm or more and less than 7.0 μm, and inorganic fibers of 7.0 μm or more is 100%. The ratio of inorganic fibers in the average fiber diameter range of each length and load here means the count ratio (count %). In this embodiment, the measurement of the length-load-average fiber diameter of the inorganic fibers was performed using cottonscope HD manufactured by Cottonscope Pty Ltd under the measurement conditions shown in Table 1. The length-loaded fiber diameter distribution system uses the measured value of the length-loaded average fiber diameter to make a statistical curve, and calculates the proportion of inorganic fibers whose length-loaded average fiber diameter is less than 4.0μm and the inorganic fiber whose length-loaded average fiber diameter is 7.0μm or more. Proportion.

When the block contains less than 13% of inorganic fibers with a length-loaded average fiber diameter of 7.0μm or more, and more than 66% of inorganic fibers with a length-loaded average fiber diameter of less than 4.0μm, the rigidity of the heat-insulating and sound-absorbing material is uneven. Low, the hardness of the heat insulation and sound-absorbing material is insufficient, resulting in lower workability. Also, when the block contains more than 58% of inorganic fibers with a length-loaded average fiber diameter of 7.0 μm or more, or when the block contains less than 20% of inorganic fibers with a length-loaded average fiber diameter of less than 4.0 μm, The voids in the heat-insulating and sound-absorbing material become larger, resulting in a decrease in sound insulation performance. On the other hand, this embodiment constitutes the block body of the heat-insulating and sound-absorbing material, because it contains 20 to 66% of inorganic fibers with a length-loaded average fiber diameter of less than 4.0 μm, and contains inorganic fibers 13 with a length-loaded average fiber diameter of 7.0 μm or more. ~58%, so the heat-insulating and sound-absorbing material has sufficient hardness required for construction, can improve the workability, and can ensure sufficient sound insulation performance.

In addition, it is more preferable that the block system contains 13 to 33% of inorganic fibers with a length-load-average fiber diameter of 7.0 μm or more. In this way, it is possible to more reliably balance high workability and high sound insulation performance.

More preferably, the block system contains 41~66% of inorganic fibers whose length-load-average fiber diameter is less than 4.0 μm. In this way, it is possible to more reliably balance high workability and high sound insulation performance.

(Inorganic fiber) Inorganic fibers can be used on the premise that they are fibrous members composed of inorganic materials such as glass wool, rock wool, slag wool, etc. However, in consideration of workability and cost, glass wool is preferred.

(Binder) The material used for the binder to block the inorganic fibers is selected before the thermosetting resin and can be selected freely. For example, phenol resin system, urea resin system, melamine resin system, resorcinol resin system, acrylic resin system, polyester resin system, sugar resin system, starch resin system, etc. can be selected. The above-mentioned binder preferably contains a thermosetting resin that is cured by a reaction selected from the group consisting of an amination reaction, an imidation reaction, an esterification reaction, and a transesterification reaction.

The weight ratio of the binder (resin content) of the block constituting the heat-insulating and sound-absorbing material is preferably 1.0 to 8.5% by weight relative to the weight of the block. In addition, the resin content rate is implemented by including: (1) cutting the glass wool blanket into 100mm×100mm into a test piece, and measuring the weight (Wa); (2) putting the cut test piece into a setting of 530 The step of decomposing the binder component in an electric furnace at ℃; and (3) Take out the test piece after the binder component has been decomposed from the electric furnace, measure the weight (Wb), and then compare the measured value (Wa) in step (1) The step of obtaining the resin content rate of the difference can be obtained according to the following formula.

Resin content (weight%) = ((Wa-Wb)/Wa)×100 If the resin content of the block constituting the heat-insulating and sound-absorbing material is less than 1.0% by weight, the rebound strength (elasticity) of the heat-insulating and sound-absorbing material is small, and the thickness of the heat-insulating and sound-absorbing material cannot be maintained. In addition, if the resin content is less than 1.0% by weight, the adhesive cannot be uniformly applied during production.

In addition, if the resin content of the block constituting the heat-insulating and sound-absorbing material is more than 8.5% by weight, the heat-insulating and sound-absorbing material becomes hard, which makes it difficult to construct the gap or the like. In addition, if the resin content is more than 8.5% by weight, the cost of the heat-insulating and sound-absorbing material increases.

In contrast, since the weight ratio of the binder (resin content) of the block constituting the heat-insulating and sound-absorbing material in this embodiment is 1.0 to 8.5% by weight, the heat-insulating and sound-absorbing material has sufficient resilience strength and can maintain the heat-insulating and sound-absorbing material thickness of. In addition, the adhesive can be evenly applied during manufacturing, and it can be easily applied to gaps and the like.

Furthermore, the adhesive strength of the adhesive is preferably 3.6~6.1N/mm ² . In addition, the strength of the adhesive can be measured in accordance with the method of measuring the tensile strength of the shell mold which includes the following steps. These steps are (1) putting 2.7% by weight of binder into 150 g of glass beads and mixing to obtain a mixture; (2) filling the mixture obtained in step (1) uniformly in an iron mold, and using an oven to heat it The binder is hardened to obtain a shell mold test piece (thickness 6mm×width 27mm×length 74mm, but the clamp part width 42mm); (3) Take the shell mold test piece obtained in step (2) out of the oven and cool to Step at room temperature; and (4) Use a universal material testing machine to measure the tensile strength of the shell mold test piece at a tensile speed of 5 mm/min.

If the adhesive strength of the heat-insulating and sound-absorbing material is less than 3.6 N/mm ² , it is necessary to increase the resin content in order to block the glass wool. In addition, if the adhesive strength of the heat-insulating and sound-absorbing material is higher than 6.1 N/mm ² , the skin irritation of the fiber will increase. On the other hand, in this embodiment, since the adhesive strength of the adhesive is 3.6 to 6.1 N/mm ² , it is possible to suppress skin irritation (stinging) without providing a film that inhibits skin irritation (stinging). In addition, the present invention is not limited to the case where no film is provided. In the case where the workability is improved, the skin irritation is more suppressed, and the film is attached (or covered) for the purpose of imparting moisture-proof performance. . The film system can be pasted on one or both sides of the heat-insulating and sound-absorbing material, and can also be covered on all four or six sides of the heat-insulating and sound-absorbing material. The heat-insulating sound-absorbing material and the film system can be pasted with an adhesive, or the films can be crimped or adhered to cover the heat-insulating sound-absorbing material. In addition, when the film is pasted (or covered), holes can be opened arbitrarily, so that the sound insulation performance, sound absorption performance and moisture permeability can be controlled.

As shown in FIG. 2, the heat-insulating and sound-absorbing material 11 of the second embodiment has a two-layer structure, and is composed of a plate-shaped block in which inorganic fibers are blocked with a binder. The block system constituting the heat-insulating and sound-absorbing material 11 includes a first layer 12 and a second layer 13. The first layer 12 is a layer formed first when the heat-insulating and sound-absorbing material 11 is formed, and the second layer 13 is a layer formed on the first layer 12. When used in a partition wall, the thickness of the heat-insulating and sound-absorbing material 11 is preferably 10-100 mm, and the thickness ratio of the first layer 12 is preferably 25-75%.

(Method of manufacturing heat-insulating and sound-absorbing material) First, the glass wool can be manufactured by liquefying the glass melt in a glass melting furnace, and then extracting a predetermined amount of glass, using a fiberizing device, heating by combustion of gas and air, and stretching the fiber with compressed air. The method of fibrillation can be exemplified by the conventionally known centrifugal method, flame method, air jet method, etc., but it is not particularly limited to these methods. An example of a fiberizing device performed by a centrifugal method may be, for example, a spin coater.

The heat-insulating and sound-absorbing material 11 can be manufactured by stacking glass wool to form a blanket. Specifically, blow out the binding agent containing any dustproof agent or other additives to the glass wool, and then use the laminated conveyor to collect the cotton according to the established basis weight to form the first layer 12, and overlap the first layer 12 to become the established The basis weight method is implemented to collect cotton to form the second layer 13, and then use the oven to harden the adhesive. Then, cut pile, trim and cut, cut the product in the short-side direction, etc., and shape it into a glass wool carpet of a predetermined size.

(Density of the heat-insulating and sound-absorbing material) The block density of the heat-insulating and sound-absorbing material 11 in this embodiment is 10-20 kg/m ³ . In addition, the "density of the bulk constituting the heat-insulating and sound-absorbing material 11" herein refers to the overall density including the first layer 12 and the second layer 13. In this embodiment, since the density of the block constituting the heat insulating and sound absorbing material 11 is also 10 to 20 kg/m ³ , the same effect as the first embodiment can be achieved. In addition, the density of the first layer 12 and the second layer 13 are preferably equal.

In this embodiment, the length-load-average fiber diameter of the inorganic fiber is also 2.0 to 8.7 μm, preferably 3.8 to 5.3 μm. In addition, the fiber length is preferably 20 mm to 200 mm. The longer the fiber length, the easier it is to increase the rigidity. With these, the same effect as the first embodiment can be achieved.

In this embodiment, the length-loaded average fiber diameter of the inorganic fibers of the first layer 12 is 0.1 to 3.0 μm larger than the length-loaded average fiber diameter of the inorganic fibers of the second layer 13. If the difference between the length-loaded average fiber diameter of the inorganic fibers of the first layer 12 and the length-loaded average fiber diameter of the second layer 13 is less than 0.1 μm, sufficient hardness cannot be obtained, and workability cannot be improved. In addition, if the length-load-average fiber diameter of the inorganic fibers of the first layer 12 and the length-load-average fiber diameter of the inorganic fibers of the second layer 13 are greater than 3.0 μm, the sound insulation performance may decrease. In contrast, according to this embodiment, since the length-loading average fiber diameter of the inorganic fibers of the first layer 12 is 0.1 to 3.0 μm larger than the length-loading average fiber diameter of the inorganic fibers of the second layer 13, sufficient hardness can be obtained. , Can improve the workability, and can also improve the sound insulation performance.

The length-load-average fiber diameter of the inorganic fibers of the layer 12 is 4.3 to 7.0 μm. If the length-load-average fiber diameter of the first layer 12 is less than 4.3 μm, sufficient hardness cannot be obtained, and the workability is not improved. In addition, if the length-load-average fiber diameter of the first layer 12 is greater than 7.0 μm, the hardness is improved, but the sound insulation performance is reduced. In contrast, according to this embodiment, since the length-load average fiber diameter of the inorganic fibers of the first layer 12 is 4.3 to 7.0 μm, sufficient hardness can be obtained, workability can be improved, and sound insulation performance can also be improved.

In addition, the total of inorganic fibers of less than 4.0 μm, inorganic fibers of 4.0 μm or more and less than 7.0 μm, and inorganic fibers of 7.0 μm or more is 100%. In addition, the ratio of inorganic fibers in the range of the average fiber diameter of each length-loaded average fiber diameter here indicates the count ratio (count %) in the same manner as in the first embodiment. According to this embodiment, by having the above-mentioned fiber diameter distribution, the same effect as the first embodiment can be achieved.

(Inorganic fiber) Inorganic fibers can be used on the premise that they are fibrous members composed of inorganic materials such as glass wool, rock wool, slag wool, etc. However, in consideration of workability and cost, glass wool is preferred.

(Binder) The material used for the binder to block the inorganic fibers is selected before the thermosetting resin and can be selected freely. For example, phenol resin system, urea resin system, melamine resin system, resorcinol resin system, acrylic resin system, polyester resin system, sugar resin system, starch resin system, etc. can be selected. The above-mentioned binder preferably contains a thermosetting resin that is cured by a reaction selected from the group consisting of an amination reaction, an imidation reaction, an esterification reaction, and a transesterification reaction.

The method of fibrillation can be exemplified by the conventionally known centrifugal method, flame method, air jet method, etc., but it is not particularly limited to these methods. An example of a fiberizing device performed by a centrifugal method may be, for example, a spin coater.

The heat-insulating and sound-absorbing material 21 can be manufactured by stacking glass wool to form a blanket. Specifically, a predetermined amount of binder containing any dustproof agent or other additives is blown toward the glass wool, and then the laminated conveyor is used to gather the cotton according to the established basis weight to form the first layer 22, which is superimposed on the first layer 22 and The second layer 23 is formed by collecting cotton in a predetermined basis weight method, and then superimposed on the second layer 23, and the third layer 24 is formed by collecting cotton according to the predetermined basis weight method, and then the adhesive is hardened by using an oven.

In addition, if the length-load average fiber diameter of the first layer 22 and the third layer 24 is greater than 7.0 μm, although the hardness is improved, the sound insulation performance is reduced. In contrast, according to this embodiment, since the length and load average fiber diameter of the inorganic fibers of the first layer 22 and the third layer 24 is 4.3 to 7.0 μm, sufficient hardness can be obtained, workability can be improved, and sound insulation can be improved. performance.

Regarding the obtained Examples 1 to 10 and Comparative Examples 1 to 3, the workability/cost, workability (skin irritation touch), and workability (product hardness) were evaluated in accordance with the following methods.

(Workability/Cost) If the weight per unit area of the inorganic fiber heat-insulating and sound-absorbing material is too large, the workability and loading efficiency will decrease. In addition, if the weight per unit area is too large, it will increase the cost. Here, with respect to Examples 1 to 10 and Comparative Examples 1 to 3, the weight per unit area of the heat-insulating and sound-absorbing material at a product thickness of 50 mm was measured, and the workability/cost was evaluated as follows. ◎: The weight per unit area is less than 800g/m ² 〇: 800g/m ² or more ~ less than 1000g/m ² △: 1000g/m ² or more and less than 1200g/m ² ×: 1200g/m ² or more

(Construction (skin irritation touch)) If the tingling sensation (skin irritation touch) when touching the inorganic fiber heat-insulating and sound-absorbing material is too large, the workability decreases. Therefore, for Examples 1 to 10 and Comparative Examples 1 to 3, 10 monitors touched the surface of the heat-insulating and sound-absorbing material, and performed a perceptual test based on the 5-stage evaluation of skin irritation based on the SD method evaluation scale 1 to 5, and according to The workability (skin irritation touch) was evaluated as follows. ◎: The average of 10 monitors is less than 2.0 〇: The average of 10 monitors is above 2.0 and less than 3.0 △: The average of 10 monitors is above 3.0 and less than 4.0 ×: The average of 10 monitors is above 4.0

(Workability (product hardness)) If the hardness of the inorganic fiber heat-insulating and sound-absorbing material is low, the workability will be reduced. Therefore, for Examples 1 to 10 and Comparative Examples 1 to 3, implement: (1) Place the heat-insulating and sound-absorbing material test piece on the flat surface of the measuring table; The step of sliding on the stage while pushing at a speed of 10cm/sec; (3) When the tip of the test piece touches the sliding stage at an angle of 45°, use a ruler to read the sag length and evaluate the workability as follows (Product hardness). However, all the sag length standards are the case where the product thickness is 50 mm. ◎: The sag length is more than 580mm, 〇: The sagging length is more than 530mm and less than 580mm △: The sagging length is more than 480mm and less than 530mm ×: The sagging length is less than 480mm

The following table shows the workability/cost, workability (skin irritation touch), and workability (product hardness) of Examples 1 to 10 and Comparative Examples 1 to 3.

[table 3] Example 1 Example 2 Example 3 Example 4 Example 5 Example 6 Example 7 Example 8 Example 9 Example 10 Comparative example 1 Comparative example 2 Comparative example 3 Workability/cost ◎ ◎ 〇 △ ◎ ◎ ◎ 〇 〇 〇 ◎ X △ Constructability Skin irritation ◎ ◎ 〇 ◎ △ △ 〇 〇 〇 〇 ◎ X X Product hardness ◎ 〇 ◎ ◎ 〇 ◎ △ 〇 △ △ X ◎ 〇

It can be seen from Tables 2 and ^{3 that Comparative Example 2 with a density of 24 kg/m 3 has} a heavier weight, resulting in a decrease in workability. In addition, in Comparative Example 1 in which there are few fibers having a fiber diameter of 7 μm or more, the product hardness is insufficient, resulting in a decrease in workability. In addition, as shown in Comparative Example 3, if the length-load-average fiber diameter is thicker with an average fiber diameter of 8.7 μm, skin irritation to the touch is greater, resulting in a decrease in workability. In contrast, in Examples 1 to 10, sufficient workability and workability (skin irritation, product hardness) can be obtained.
