Description

  The present invention is a vehicle chemical volatilizer installed in the interior of an automobile, and maintains the shape of the liquid absorbent core that volatilizes the chemical liquid stably even at high temperatures, and the chemical vaporization rate in the later stage of use decreases. The present invention relates to a chemical vaporizer for vehicle compartment that is difficult and can suppress the residual chemical in the container at the end of use.

  2. Description of the Related Art Conventionally, a chemical liquid volatilizer that volatilizes a chemical liquid such as an aromatic liquid has been used in order to impart a fragrance or the like to the interior of an automobile to create a comfortable space. As described above, the chemical volatilizer installed in the interior of the automobile is required to be designed so that the chemical liquid in the chemical volatilizer does not spill out due to shaking or the like when traveling on a rough road.

  Conventionally, as a chemical volatilizer that can prevent chemical spills, a membrane-type chemical volatilizer that covers the opening of a container that contains a chemical with a membrane that allows gas to pass through, and volatilizes the chemical through the membrane has been proposed. (For example, refer to Patent Document 1). However, the membrane type chemical volatilizer has a drawback that it cannot cope with a wide range of user preferences because the composition of the chemical that can be volatilized through the membrane is restricted.

JP 2014-94619 A

  The interior of an automobile becomes hot in the summer, and in the winter, due to the use of an air conditioner, etc., the area near the air vent becomes hot, so when a membrane-type chemical volatilizer is used in an automobile, depending on the type of film or chemical Has the disadvantage that the volatilization rate of the chemical solution increases and the desired volatility cannot be achieved. Conventionally, it is known that an increase in the volatilization rate of a chemical solution under a high temperature condition can be suppressed by using a paraffinic hydrocarbon having a large molecular weight as a solvent for the chemical solution to be volatilized. However, when such a solvent is used, the volatilization rate of the chemical solution is reduced in the latter stage of use, and the chemical solution is likely to remain in a state where it does not volatilize in the chemical volatilizer, so that the user can determine the end of the chemical volatilizer. Therefore, there is a problem in that a chemical solution that is difficult to volatilize is left forever.

  However, the present inventor has intensively studied to develop a vehicle chemical volatilizer for use in automobiles. As a result, a liquid absorbent made of polyolefin which is widely used as a chemical volatilization member in a chemical vaporizer for rooms. A new problem has also been found that when a chemical liquid containing paraffinic hydrocarbon as a solvent is volatilized using a wick, the liquid wick is deformed and collapses under high temperature conditions. In such a chemical volatilizer that causes deformation of the liquid absorbent core at a high temperature, not only does the rate of volatilization of the chemical liquid decrease, but also there is a gap between the container and the liquid absorbent core and the chemical liquid is likely to spill. Cannot be used in a car.

  As described above, in the conventional technology, when paraffinic hydrocarbon is used as a solvent for the chemical solution to be volatilized, the volatilization rate of the chemical solution is lowered in the later stage of use, and the chemical solution is likely to remain in the container. When using a hydrocarbon based as a solvent for a chemical solution, there is a problem that a liquid absorbent core made of polyolefin that is widely used in a room chemical solution volatilizer deforms at a high temperature. For this reason, in the prior art, a vehicle chemical volatilizer that can satisfy the required characteristics when used indoors in an automobile has not been developed.

  Therefore, the object of the present invention is to maintain the shape of the liquid absorbent core that volatilizes the chemical liquid stably even at high temperatures, and the chemical vaporization rate in the latter stage of use is unlikely to decrease, so that the chemical liquid remains in the container at the end of use. It is providing the chemical | medical solution volatilizer for vehicle interiors which can be suppressed.

  The present inventor has intensively studied to solve the above problems, and in a chemical liquid volatilizer, a chemical liquid containing paraffinic hydrocarbon and a material containing polyester and / or nylon as a volatilizing member for volatilizing the chemical liquid are formed. By using it in combination with the liquid absorbent core, the shape of the liquid absorbent core can be stably maintained even at high temperatures despite the use of paraffinic hydrocarbons, and it can be used as a chemical vaporizer for vehicle compartments. I found out that I can do it. Furthermore, by combining the chemical solution and the liquid absorbent core, even when used in an environment exposed to high temperatures such as in the interior of an automobile, the volatilization rate of the chemical solution at the later stage of use is unlikely to decrease, and the chemical solution in the container at the end of use. It has also been found that the residual of can be suppressed. The present invention has been completed by further studies based on these findings.

The structure of the liquid absorption wick and the arrangement site on the bottom surface of the container at the lower end thereof are desirably provided with the configuration described later.

Liquid Absorbing Core The vehicle liquid chemical volatilizer according to the present invention includes the liquid absorbing core 2 in order to absorb the chemical liquid stored in the container and volatilize it into the interior of the automobile.

  In the present invention, the liquid absorbent core 2 is made of a material containing polyester and / or nylon. By using the liquid absorbent core 2 formed of a material containing polyester and / or nylon in this way, even if the chemical liquid to be volatilized contains paraffinic hydrocarbons, deformation of the liquid absorbent core 2 is suppressed at high temperatures. And it becomes possible to maintain the shape stably.

  Although it does not restrict | limit especially about the kind of polyester used as a raw material of the liquid absorption core 2, For example, a polyethylene terephthalate, a polybutylene terephthalate, a polyethylene naphthalate etc. are mentioned. These polyesters may be used individually by 1 type, and may be used in combination of 2 or more type. Among these polyesters, polyethylene terephthalate is preferably used from the viewpoint of more effectively suppressing deformation of the absorbent core 2 at a high temperature.

  Further, the type of nylon used as the material for the liquid absorbent core 2 is not particularly limited, and examples thereof include nylon 6, nylon 6,6, nylon 4,6, and the like. These nylons may be used individually by 1 type, and may be used in combination of 2 or more type.

  The liquid absorbent core 2 may be selected from polyester and nylon and used alone or in combination of two or more thereof.

  The absorbent core 2 includes, as necessary, polyester and / or nylon as a constituent material, polyolefin such as polyethylene and polypropylene, acrylic, vinylon, and other resin materials such as polyurethane as necessary. You may go out. However, since polyolefin causes deformation of the liquid absorbent core at a high temperature, the liquid absorbent core 2 used in the present invention preferably has a low content of polyolefin and is substantially free of polyolefin. More preferably. Specifically, the polyolefin content in the material forming the liquid absorbent core 2 is usually 50% by weight or less, preferably 30% by weight or less, and more preferably 0% by weight.

  The liquid absorption core 2 may be formed of a material containing polyester and / or nylon so as to be able to suck up the chemical liquid in the container 1. For example, a fibrous polyester and / or nylon is welded or bonded to a predetermined shape, a fibrous polyester and / or nylon is knitted into a predetermined shape, and a non-woven polyester and / or nylon is a predetermined shape. And those obtained by forming polyester and / or nylon into a predetermined shape in the form of a sponge.

  The shape of the liquid absorbent core 2 may be any shape that can suck up the chemical solution in the container 1 and volatilize the chemical solution outside the container 1, and specifically includes a rod shape. In addition, the length of the liquid absorbent wick 2 is preferably set so that the upper end of the liquid absorbent wick 2 protrudes from the opening 121 of the container 1 when being brought into contact with the bottom 111 of the container 1. .

  The liquid absorption wick 2 is inserted from the opening 121 of the container 1, and the lower end 21 thereof is placed in contact with the bottom surface 111 of the container 1. Moreover, it is preferable that at least a part of the lower end portion 21 of the liquid absorbent core 2 is in contact with the edge portion 1111 of the bottom surface 111 of the container. Thus, even if the remaining amount of the chemical solution is reduced in the later stage of use, the absorbent core 2 can be used even if the lower end portion 21 of the liquid absorbent core 2 is in contact with the edge portion 1111 of the bottom surface 111 of the container. It is possible to easily suck up the chemical liquid and to easily use up the chemical solution. FIG. 2 shows a mode in which the lower end portion 21 of the liquid absorbent core 2 is in contact with the left and right edge portions 1111 of the bottom surface 111 of the container 1. Moreover, as shown to Fig.7 (a), the diameter of the lower end part 21 of the liquid absorption core 2 may be small, and you may contact | abut only to one edge 1111, or as shown in FIG.7 (b), You may contact | abut either edge part (the back side in this example) of the bottom face 111.

Mounting member In the vehicle liquid chemical volatilizer according to the present invention, in order to stably hold the liquid absorbent core 2, the liquid absorbent core 2 is attached to the opening 121 of the container as shown in FIGS. The member 5 may be attached. The attachment member 5 includes a cylindrical attachment main body 51 that is press-fitted into the inner wall surface of the neck portion 12 of the container 1, and a flange portion 52 that extends radially outward from the upper edge of the attachment main body 51. The liquid absorption core 2 is inserted into the mounting body 51. Moreover, the flange part 52 is arrange | positioned so that the opening periphery of the neck part 12 may be covered from upper direction.

  Further, a groove (not shown) extending in the vertical direction is formed on the inner wall surface of the mounting body 51, and when the liquid absorbing core 2 is inserted, the liquid absorbing core 2 and the mounting body 51 are inserted by this groove. A gap is formed between the two. This gap communicates the internal space of the container 1 with the outside. Thereby, for example, when the container 1 is used in a high-temperature environment and the internal pressure of the container 1 increases, the air in the container 1 is discharged to the outside through the gap. On the other hand, if such a gap is not provided, there is a possibility that the chemical liquid is excessively pushed out through the liquid absorbent core 2 when the internal pressure rises.

In order to fix and install the fixing part and the support body in the vehicle liquid chemical volatilizer of the present invention to the interior member of the automobile, the support body for supporting the container and the installation part in the interior of the automobile are attached. You may further provide the fixing | fixed part.

Usage Mode The chemical liquid volatilizer for a vehicle compartment according to the present invention is installed in an indoor member such as an air conditioner of an automobile, a blower opening of a defroster, or a dashboard for the purpose of volatilizing the chemical liquid in the interior of the automobile.

  EXAMPLES The present invention will be specifically described below with reference to examples and the like, but the present invention is not limited to these. Hereinafter, polyethylene terephthalate may be abbreviated as “PET”.

Test example 1
A liquid absorption core (column shape, diameter 8 mm, length 50 mm) formed of the material shown in Table 1, solvent (chemical solution) and screw tube (diameter 24 mm, height 50 mm, capacity 13.5 ml) shown in Table 1. Got ready. In addition, the liquid absorption core was produced by shape | molding in a cylindrical shape by thermoforming each fibrous raw material. Moreover, the liquid absorption core formed using 2 types of resin was produced by shape | molding in cylindrical shape by mixing each resin of fibrous form with a predetermined ratio, and thermoforming.

4.5 g of each solvent was filled into a screw tube, a liquid absorption core was inserted into the screw tube, and the mixture was allowed to stand at 80 ° C. for 3 hours. The state of the liquid absorbent core after 3 hours was observed, and the shape stability of the liquid absorbent core was evaluated according to the following criteria.
<Judgment criteria for shape stability of liquid core>
○: No change in the shape of the liquid absorbent core Δ: Slight deformation of the liquid absorbent core is observed x: The liquid absorbent core is greatly deformed.

  The obtained results are shown in Table 1. When the liquid absorbent core made of polypropylene and / or polyethylene was impregnated with paraffinic hydrocarbon, deformation occurred after standing at 80 ° C. for 3 hours (Comparative Examples 1 to 9). In addition, since the liquid absorption core formed of polypropylene and / or polyethylene was not impregnated with paraffinic hydrocarbons and was left to stand at 80 ° C. for 3 hours in air, no deformation was observed. It was confirmed that the deformation of the absorbent core observed in Examples 1 to 9 was caused by paraffinic hydrocarbons. In contrast, a liquid absorbent core made of nylon and / or polyethylene terephthalate can be stably maintained in shape without being deformed after standing at 80 ° C. for 3 hours even when impregnated with paraffinic hydrocarbons. (Examples 1 to 9). In addition, even if the absorbent core is made of 50% by weight of polyethylene terephthalate and 50% by weight of polyethylene or is impregnated with paraffinic hydrocarbons, the shape remains stable without being deformed after standing at 80 ° C. for 3 hours. (Examples 10 to 12).

Test example 2
Liquid absorbent core (column shape, diameter 8 mm, length 50 mm) formed of the material shown in Table 2, chemical solution containing 60% by weight of solvent and 40% by weight of limonene shown in Table 2, and screw tube (24 mm in diameter, height) 50 mm, capacity 13.5 ml) was prepared. In addition, the liquid absorption core was produced by shape | molding in a cylindrical shape by thermoforming each fibrous raw material. Moreover, the liquid absorption core formed using 2 types of resin was produced by shape | molding in cylindrical shape by mixing each resin of fibrous form with a predetermined ratio, and thermoforming.

  4.5 g of each chemical solution was filled in a screw tube, a liquid absorption core was inserted into the screw tube, and the mixture was allowed to stand at 80 ° C. for 3 hours. The state of the liquid absorbent core after 3 hours was observed, and the shape stability of the liquid absorbent core was evaluated in the same manner as in Test Example 1.

  The obtained results are shown in Table 2. Also from this result, it was confirmed that the liquid absorbent core formed of nylon and / or polyethylene terephthalate can stably maintain its shape at high temperatures even for chemical liquids containing paraffinic hydrocarbons.

Test example 3
Liquid absorption core (column shape, diameter 8 mm, length 50 mm) formed of the material shown in Table 3, carbon number 12-16 isoparaffin (trade name “IP Solvent 2028”, manufactured by Idemitsu Kosan Co., Ltd., carbon number 16 An isoparaffin containing 70 wt% or more, an initial boiling point of 213 ° C. at normal pressure, a dry point of 262 ° C. at normal pressure (chemical solution), and a screw tube (diameter 21 mm, height 45 mm, capacity 9 ml) were prepared. In addition, the liquid absorption core was produced by shape | molding in a cylindrical shape by thermoforming each fibrous raw material. Moreover, the liquid absorption core formed using 2 types of resin was produced by shape | molding in cylindrical shape by mixing each resin of fibrous form with a predetermined ratio, and thermoforming.

  5 g of isoparaffin having 12 to 16 carbon atoms was filled in a screw tube, a liquid absorbent core was inserted into the screw tube, and the mixture was allowed to stand at 80 ° C. for 12 hours. From the start of standing, the remaining amount of isoparaffin was measured every 0.5 hours. From the measured amount of isoparaffin remaining at each time, the isoparaffin volatilization rate (g / hr; initial volatilization rate) from the start of standing until 1 hour and the isoparaffin volatilization from 9 hours to 12 hours after standing. The rate (g / hour; late volatilization rate) was determined, and the retention rate (%) of the late volatilization rate was calculated according to the following formula.

The obtained results are shown in Table 3.
When using a liquid absorbent core made of only polyethylene terephthalate or polyethylene terephthalate and polypropylene (Examples 16 and 17), when using a liquid absorbent core made only of polypropylene (Comparative Example 11) Compared to the retention rate of the late volatilization rate, the chemical solution hardly remained in the container at the end of use. In particular, in the case of using a liquid absorbent core formed only of polyethylene terephthalate (Example 16), as compared with the case of using a liquid absorbent core formed only of polypropylene (Comparative Example 11), late volatilization The maintenance rate of speed was much higher.

  Further, when the retention rate of the late volatilization rate was calculated in the same manner as in Example 16 except that “IP solvent 1016” and “IP solvent 1620” were used instead of “IP solvent 2028”, the liquid absorption core Compared to the case where 100% by weight of polypropylene was used as the material, the retention rate of the late volatilization rate could be increased, but when comparing the volatilization rate of each, compared to “IP Solvent 1016”, “IP Solvent 1620” ”And“ IP Solvent 2028 ”were slower and continued to evaporate for a long time. That is, from this result, the volatilization performance can be further improved by adopting paraffinic hydrocarbons having an initial boiling point of about 80 to 270 ° C. or plasma fluid isoparaffins having 9 to 16 carbon atoms. confirmed.

Test example 4
Liquid absorption core (column shape, diameter 8 mm, length 50 mm) formed from the materials shown in Table 4 and isoparaffin having 4 to 9 carbon atoms (trade name “IP Solvent 1016”, manufactured by Idemitsu Kosan Co., Ltd., having 8 carbon atoms. Containing 80% by weight or more of isoparaffin, initial boiling point at ordinary pressure of 73 ° C., dry point of 140 ° C. at normal pressure), containing 80% by weight or more of isoparaffin having 8 carbon atoms (chemical solution), and screw tube (diameter 21 mm , Height 45 mm, capacity 9 ml). In addition, the liquid absorption core was produced by shape | molding in a cylindrical shape by thermoforming each fibrous raw material. Moreover, the liquid absorption core formed using 2 types of resin was produced by shape | molding in cylindrical shape by mixing each resin of fibrous form with a predetermined ratio, and thermoforming.

  Fill the screw tube with 5 g of isoparaffin having 4 to 9 carbon atoms, insert the liquid absorption core into this screw tube, leave it at 25 ° C. for 12 hours, and maintain the late volatilization rate in the same manner as in Test Example 3 ( %).

  Table 4 shows the obtained results. As a result, when left at 25 ° C., the initial volatilization rate maintenance rate was high in both Examples 18-19 and Comparative Example 12. From this result, it was confirmed that the decrease in the maintenance rate of the volatilization rate of Comparative Example 11 in Test Example 3 was caused under high temperature conditions.

Test Example 5
Containers A and B shown in Table 5 contain isoparaffins having 12 to 16 carbon atoms (trade name “IP Solvent 2028”, manufactured by Idemitsu Kosan Co., Ltd., containing 70 wt% or more of isoparaffins having 16 carbon atoms, initial distillation at normal pressure. The solution was charged with 5 g of a point 213 ° C., a dry point 262 ° C. at normal pressure) (chemical solution), the absorbent core A was installed in the container A, and the absorbent core B was installed in the container B, and allowed to stand at 80 ° C. for 36 hours. The liquid absorbent cores A and B are both produced by mixing into a cylindrical shape by mixing 50% by weight of fibrous polyethylene terephthalate and 50% by weight of fibrous polypropylene and thermoforming them. The amount of isoparaffin remaining in the container was measured after 36 hours of standing.

  The results obtained are shown in Table 5. From this result, even when the container B was used, the amount of isoparaffin remaining after 36 hours of standing was very small. However, when the container A was used, the isoparaffin after 36 hours of standing still remained. There wasn't. This is considered to be because isoparaffin in the container A gathers in the groove due to surface tension, and easily gathers in the liquid absorption core along the protrusion.

  In addition, as a reference, a test similar to the above was conducted using dipropylene glycol monoethyl ether and 3-methoxy-3-methyl-1-butanol instead of isoparaffin having 12 to 16 carbon atoms. When A was used, these solvents did not remain at all after standing at 20 ° C. for 36 hours.
