DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spray composition for catching small insects such as fly, and more particularly to a composition suitable for air spray and the like.

[0002]

2. Description of the Related Art Conventionally, small insect trapping adhesives have been generally applied by a method such as brushing. However, such a method has a problem in that the application operation is complicated.

[0003]

SUMMARY OF THE INVENTION The present invention relates to a spray,
In particular, it is an object of the present invention to provide an adhesive composition for capturing small insects that can be applied by a simple operation using air spray.

[0004]

SUMMARY OF THE INVENTION The present invention provides a polybutene,
An object of the present invention is to provide a spray composition for trapping small insects, comprising a water-based emulsion containing water, an emulsifier and an attractant.

The present invention will be described in more detail. The polybutene used in the composition of the present invention has a number average molecular weight of 200 to 200.
A range of 4,000 is suitable. If the number average molecular weight is less than 200, the fluidity of the composition after coating becomes excessive, while if the molecular weight exceeds 4,000, it becomes difficult to spray because the viscosity is too high, and the initial adhesive strength Are not preferred. The amount of polybutene is 10 to 80% by weight, preferably 20 to 80% by weight.
50% by weight. If the amount is less than 10% by weight, the ability to capture small insects will decrease, while if it exceeds 80% by weight, the viscosity will be too high and the spraying properties will undesirably decrease.

The amount of water used in the present invention is 20 to 8
0% by weight, preferably 25 to 70% by weight. If the amount is less than 20% by weight, the viscosity becomes too high and the spraying property is reduced. On the other hand, if it exceeds 80% by weight, the ability to catch small insects is undesirably reduced.

In the present invention, any emulsifier can be used, and examples thereof include polyoxyalkylene alkyl phenyl ether sulfate ammonium salt and dodecyl benzene sulfonate amine salt. The amount is suitably 0.1 to 20% by weight.

[0008] As the attractant, honey and the like are suitable for small insects such as flies targeted by the spray composition of the present invention. The amount is suitably 0.1 to 5% by weight. If the amount is less than 0.1% by weight, there is no effect. If the amount exceeds 5% by weight, the attracting effect is impaired. In addition, honey is not preferred because the viscosity is increased.

[0009] In order to enhance the trapping performance of small insects, it is preferable to mix rubber. As the rubber compounded for this purpose, polyisobutylene, butyl rubber or a mixture thereof having a viscosity average molecular weight in the range of 20,000 to 2 million is suitable. If the molecular weight of the rubber is out of this range,
It is not preferable because the tackiness of small insects is reduced due to insufficient tackiness. Since these rubbers have good compatibility with polybutene, they can improve the adhesion to small insects. An appropriate amount of rubber is 0.1 to 20% by weight. If the content is less than 0.1% by weight, it is difficult to exhibit the effect of improving the trapping performance. Any of them is not preferable because the performance of capturing small insects is reduced.

In the present invention, it is preferable to further add a flow inhibitor. When the composition of the present invention is used, tackiness is developed after water is evaporated and dried after spraying, but when the adhesive causes a flow on an inclined surface (which may be a vertical surface) in a dry state. Cannot function as an adhesive as a result. In order to prevent such a phenomenon, a flow inhibitor is added. As the above-mentioned flow inhibitor, hydrophilic water-insoluble inorganic fine particles, for example, fine powder of silica, alumina, zeolite,
Organic bentonite or talc is exemplified. Of these, hydrophilic finely divided silica is preferred because of its high flow prevention effect. The compounding amount is 0.1 to 20% by weight, preferably 0.5 to 10% by weight. If the amount is less than 0.1% by weight, it is difficult to expect a flow preventing effect.
Exceeding the weight% is not preferred because the sprayability is reduced.

Further, the composition of the present invention may contain optional components, such as preservatives, as long as the effects of the present invention are not impaired. The method for producing the aqueous emulsion of the present invention is not particularly limited, and a known method can be used.

To apply the composition comprising the aqueous emulsion of the present invention, a spray is used. The method of using a spray is not particularly limited, and for example, a propellant such as LPG can be used. However, when LPG is used as a propellant, safety against fire becomes a problem, and when propellant or the like is used, environmental safety becomes a problem. Furthermore, when a propellant is used, it is necessary to use a pressure-resistant container, which is expensive. Therefore, a slight air pressure is manually generated to increase the internal pressure of the container,
A so-called air spray method of spraying using this internal pressure is preferable. The compositions of the present invention are those most suitable for performing air spraying.

In order to perform air spraying, it is important that the viscosity of the composition at 25 ° C. is 1,000 cP or less, preferably 50 to 900 cP, more preferably 200 to 400 cP. If the viscosity exceeds 1,000 cP, it is not preferable because the air spray property is low even if the small insect trapping performance is high. In the present invention, it is necessary to determine the mixing ratio of each component so that the viscosity of the composition falls within the above range. Usually, when the emulsion viscosity is low, the solid content of the emulsion is low, and it is considered that the application amount of the adhesive is inevitably small. Therefore, it is expected that the adhesive performance and, consequently, the capturing performance of small insects are low. However, the composition of the present invention
Despite having a low viscosity, it has a sufficient catching performance against small insects, especially fly, by using a suitable attractant as an essential component. Further, the composition of the present invention is stable in an emulsion state.

[0014]

The present invention will be described below with reference to examples. Various components other than the attractant were blended at the ratio shown in Table 1 to prepare an emulsion stock solution. Table 1 Composition ratio (wt%) Polybutene: Number average molecular weight 1,260 51.3 Rubber: Polyisobutylene, viscosity average molecular weight 1,200,000 1.0 Flow inhibitor: Silica gel (trade name: Aerosil 130, manufactured by Nippon Aerosil Co., Ltd.) 2.7 Emulsifier: Polyoxyethylene alkyl phenyl ether sulfate ammonium salt 3.6 Emulsifier: Dodecylbenzenesulfonate amine salt 1.9 Antifoamer: Silicon (trade name: SN Deformer 483, manufactured by San Nopco) 0.2 Water: 39.3 Total 100.0 wt% After diluting the above emulsion stock solution to various concentrations with water, honey as an attractant was added to the stock solution and each diluted solution in an amount of 0.2% each.
5% by weight were added to obtain six types of spray composition samples having different viscosities. Table 2 shows the results of examining the suitability of the viscosity and air sprayability of these samples together with the concentration of the stock solution at the time of dilution. Table 2 Sample No. Concentration (%) Viscosity (cP, 25 ° C.) Air spray suitability 1 100 4,000 Not suitable 2 90 2,000 Not suitable 3 80 1,000 Slightly poor, usable 470 400 Suitable 5 67 300 Suitable 6 50 200 suitable

<Capture Performance Experiment> Three samples of Sample Nos. 4, 5 and 6 in Table 2 were applied to a B4 plate mount by air spray to obtain coated sheets. After leaving it to stand for one hour and drying, two coated sheets were stuck on the wall of a barn to test fly catching performance. Three days later, the number of fly catches was investigated. As a result, the total of two coated sheets of each sample was 92%.
One, 654 and 272 showed excellent capture performance.

[0016]

The composition for capturing small insects of the present invention is suitable for spraying, especially for air spraying. That is, since spraying can be performed without using a propellant such as LPG, safety is high and the cost is low.
