Abstract

PROBLEM TO BE SOLVED: To enable adjustment of time required for impregnation of liquid voltage substance and volatilization with a higher designing freedom without fear of dropping breakage by achieving a binding of a crock chip using a resin having resistance to chemicals and solvents under a pressure and controlling a binding density of the cork in a specified range. SOLUTION: In a method for making an impregnation body by a pressure binding of a cork chip using a resin. For example, when a pressure of 250kg/cm<2> is applied to the mixture of 89.5% cork chip, 8.8% industrial polyurethane polymer and 1.7% water, an impregnation body (cork molded product) having the density of 0.18kg/cm<3> is obtained and when 350kg/cm<2> , density of 0.21kg/cm<3> is obtained. Thus, the impregnation body with varied densities of the cork is obtained by varying a pressurizing force. In the impregnation of the impregnation body thus obtained with various liquid volatile substances a difference ion the density inevitably differentiates the time required for the impregnation with the volatile substances. The impregnation is accomplished within 3min. with the density within a range of 0.10-0.30g/cm<3> .

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an impregnated body capable of repeatedly impregnating a liquid volatile substance such as insecticide, insect repellent, aroma, deodorant, fungicide and the like.

[0002]

2. Description of the Related Art As a conventional impregnated body of this kind, deodorant,
For aroma, there are ceramics, wood cut into an arbitrary shape, and perfume pieces packed in containers.

As an aromatic material using wood, Japanese Patent Application Laid-Open No. Sho 60-209514 and Japanese Patent Publication No. 3-10
No. 338 and Japanese Patent Publication No. 4-31711 are known, and as a deodorant using cork, it is known from JP-A-1-305958.

[0004]

However, the above-mentioned ceramics require a long time (several hours) for impregnation with a volatile substance, and in the case of injecting a volatile substance into this, If tilted or carelessly moved after injection, there is a problem that the volatile substance spills and contaminates the surroundings. In addition, there was a risk of damage due to falling, so care was required in handling.

On the other hand, in the case of using wood or wood chips as proposed in Japanese Patent Application Laid-Open No. 60-209514, the impregnation rate is extremely low because the impregnation method of dipping or spraying is employed. Because sufficient impregnation capacity was not obtained, satisfactory volatilization performance could not be obtained,
In addition, it was inconvenient for the end user to use repeatedly. In addition, those that cut and process wood are difficult to mass-produce and tend to be expensive, and those that use wood chips are often used in bags or the like, which tends to reduce the degree of freedom in design. .

Further, Japanese Patent Publication No. 3-10338 proposes a method in which a fragrance and wood flour are mixed at the time of production and the mixture is molded. And the like, which requires facilities and time and effort, and thus is not suitable for repeated use, and thus cannot be said to be simple and economical.

The one proposed in Japanese Patent Publication No. 4-31711 uses a polyvinyl acetal-based binder, so it is good for enjoying the aroma of the base material, but it has good chemical resistance and solvent resistance. However, it is not suitable for use with newly added fragrances, and cannot be applied to insecticides, insect repellents, deodorants, fungicides, and the like, and its use tends to be limited.

Japanese Unexamined Patent Publication (Kokai) No. 1-305958 discloses a method in which cork is granulated and used by impregnating or attaching a deodorant thereto. The trouble due to being a body was similar to that of the above-mentioned other wood chips, wood flour and the like.

The present invention has been made in consideration of the above, has no fear of being damaged by falling, has a high degree of freedom in design, can adjust the time required for impregnation with a liquid volatile substance, and can also adjust the volatilization. It is an object of the present invention to provide an impregnated body of a volatile substance which has been made possible.

[0010]

In order to achieve the above object, an impregnated body of a volatile substance according to the present invention comprises a cork chip which is bonded by pressure using a resin having chemical resistance and solvent resistance. And the binding density of this cork is 0.10 to 0.30 g / c
m ³ .

Further, the impregnated body of the volatile substance according to the present invention has a constitution in which cork chips are pressure-bonded while carbonizing by heating, and the bonding density is in the range of 0.10 to 0.30 g / cm ^3. It has become.

A urethane resin is used as the resin in the resin to be bonded by pressure. Each of the impregnated bodies is used by being housed in a container. The surface of the impregnated body is printed, and a volatilization adjusting material made of an impermeable film is formed on the surface.

[0013]

[Operation] The impregnated body which has been bound under pressure is impregnated with a liquid volatile substance such as an insecticide by dropping. At this time, the time required for impregnation and the volatilization rate can be arbitrarily changed depending on the binding density.

[0014]

BEST MODE FOR CARRYING OUT THE INVENTION As an example of a method for producing an impregnated body according to the present invention in which a cork chip is pressure-bonded using a resin, for example, 89.5% of a cork chip is mixed with industrial pre-urethane. Polymer (trade name: AGLOMERANTE)
-P954) Add 8.8%, water 1.7%, and add 250 kg
/ Cm ² pressure gives a density of 0.18 kg / cm
³ impregnated body (cork molded body) was obtained, 350 kg / c
Density 0.21k cork by applying a pressure of m ²
An impregnated body (cork molded body) of g / cm ² is obtained. By changing the pressing force in various ways, impregnated bodies (cork molded bodies) having various cork densities were obtained.

On the other hand, as a method for producing an impregnated body in which cork chips are bonded while heating and carbonizing, the cork chips are bonded while heating at a temperature at which the cork chips are carbonized. Also in this case, the density of the impregnated body can be variously changed depending on the pressure at the time of binding.

The impregnated body constituted as described above is impregnated with various liquid volatile substances. At this time, although the time required for the impregnation of the volatile substance differs depending on the difference in the density of the impregnated body, the impregnation could be performed within 3 minutes within the density of 0.10 to 0.30 kg / cm ³ .

The urethane resin used for molding the impregnated body is excellent in chemical resistance, solvent resistance and elasticity, and is suitable as a material having both the function as an impregnated body and the texture of cork.

By impregnating the impregnated body impregnated with the volatile substance as described above and then putting the impregnated body into a container, the amount of the volatile substance volatilized can be adjusted and the safety against liquid leakage can be reduced. Functionality can be enhanced, for example, it can be increased or installed easily.

Further, by utilizing the softness of the above-mentioned impregnated body in the form of a plate or the like, one or a plurality of impermeable membranes are attached to the volatilization surface of the impregnated material with a thumbtack-like volatilization adjusting material. The amount of volatilization can also be adjusted. The volatilization surface may be arbitrarily printed. This printing enhances the aesthetic value of the impregnated body.

(Experimental Example 1) In an impregnated body in which cork chips were pressure-bonded using a resin, the impregnated body having various cork bonding densities was added with a fragrance of 58% and a methoxymethylbutanol solvent 42. 1.5 g of a mixed solution with
The time until all of this was impregnated was measured. The results are shown in Table 1 and FIG.

[0021]

[Table 1]

As can be seen from Table 1 and FIG. 1, if the impregnated body has a binding density of cork of 0.3 g / cm ³ or less, it can be used in an impregnating time of 3 minutes or less. If it is small, the holding power of the liquid is insufficient, so at least 0.1 g /
It is better to have cm ³ . The preferable range is 0.15 to 0.20 g / cm ³ .

(Experimental example 2) The size is 70 mm × 70 mm
× 8mm plate shape and cork binding density 0.18g
/ Cm ³ and 0.25 g / cm ³ ,
A cork chip was formed in the same manner as in Experimental Example 1 above,
Each impregnated body was impregnated with 4.5 g of a mixture of 55% of a rose-based flavor and 45% of a methoxymethylbutanol-based solvent. Then, the change of the amount of volatilization with respect to the elapsed days when one side surface in the thickness direction of each impregnated body was closed and volatilized was examined. The result is shown in FIG. As is clear from these results, the amount of volatilization with respect to the elapsed days differs depending on the binding density of cork, and it is found that the smaller binding density is more.

(Experimental Example 3) The size is 85 mm × 85 mm
× 8mm plate shape and cork binding density 0.18g
/ Cm ³ of a mixed liquid 4.55 in which a green-based flavor was made 58% with a methoxymethylbutanol-based solvent on an impregnated body formed by forming a cork chip by the same manufacturing method as in Example 1 above.
g and 4.55 g of a mixed solution made 58% with an iso-paraffinic solvent were separately impregnated. Then, the change of the amount of volatilization with respect to the elapsed days when one side surface in the thickness direction of each impregnated body was closed and volatilized was examined. The result is shown in FIG.

(Experimental example 4) The surface shape is 85 mm x 85 m
m and a plate thickness of 5 mm and 8 mm. Each of the impregnated bodies having the same configuration as that of each of the above embodiments and having a cork binding density of 0.18 g / cm ³ was coated with a lavender. The mixture was impregnated with a mixed solution of 58% of a perfume-based flavor and 42% of a methoxymethylbutanol-based solvent. Then, changes in the elapsed days and changes in the amount of volatilization when the one side surface in the thickness direction of both impregnated bodies was closed and volatilized were examined. FIG. 4 shows the results.

In Experimental Examples 3 and 4, even if the impregnated body has the same binding density of cork, the number of elapsed days depends on the difference in the volatile substance impregnated in the impregnated body and the difference in the plate thickness of the impregnated body. It can be said that the amount of volatilization is different.

[0027]

According to the present invention, a cork chip is pressure-bonded using a resin or while being heated and carbonized, and the bonding density is set to 0.10 to 0.30 g / cm ³ . Despite being a solid impregnated body, the possibility of damage due to falling can be eliminated. In addition, by being formed by pressure bonding, the shape can be freely set to some extent, and the degree of freedom in design can be improved. In addition, a sufficient amount of impregnation can be obtained for the impregnation with the volatile substance in a short time, and satisfactory volatilization performance can be obtained. The impregnation with the volatile substance can be easily performed, and it is convenient and economical to repeatedly impregnate and use the volatile substance.

Further, by using a chemical-resistant and solvent-resistant material for the molding resin, various volatile substances can be impregnated.
It can be widely used as an insect repellent, insecticide, fragrance, deodorant, and fungicide, and its utility value is enhanced.

Further, by printing on the surface of the impregnated body, the aesthetic value of the impregnated body can be improved, and by impregnating the surface of the impregnated body with a volatilization adjusting material comprising an impermeable film, It can be seen that the amount of volatile substance emitted from the body per hour is adjusted.
