By the way, a small animal control resin composition and a small animal control resin molded product using the same are required to have high fast-acting properties of a small animal control agent for harmful small animals as a basic performance. Such performance, the small animal control resin composition or the body surface of the small animal in contact with the small animal control resin molded article, to efficiently transfer the small animal control agent, and the small animal control agent transferred to the body surface It is exerted by being efficiently taken into the body of.

In particular, in recent years, since the number of small animals with resistance to small animal control agents is increasing, it is possible to efficiently attach a larger amount of small animal control agents to the body surface of small animals than before, and small animals that have migrated to the body surface. It has become an important technical issue to promptly incorporate the control agent into the body of small animals.

However, in the past, the idea itself of efficiently adhering a large amount of a small animal control agent to the body surface of a small animal, and quickly incorporating the small animal control agent transferred to the body surface into the body of a small animal is not known, Most of the attempts are made to deal with this by increasing the amount of the small animal control agent added to the small animal control resin composition or the small animal control resin molded product. Therefore, the high-performance small animal control resin composition and the small animal control resin molded product have a problem that the cost tends to be high.

The present invention has been made in view of such circumstances of the prior art, and an object thereof is to provide a small animal-controlling resin composition and a small-animal-controlling resin molded article that have a high immediate effect on harmful small animals. is there.

The drug surface amount was measured by washing the sample surface with a solvent from the samples according to Examples 1 to 32 and the samples according to Comparative Examples 1 to 22, and measuring the washed solution by liquid chromatography.

As is clear from Examples 1 to 8 of FIG. 4 and Comparative Example 1 of FIG. 6, the measurement of the drug surface amount of the experimental sample using polyamide 12 as the base resin is in the range of 2.2 to 2.5 μg/cm ² . It is inside. Further, as is clear from Examples 9 to 16 of FIG. 4 and Comparative example 2 of FIG. 6, the measurement of the drug surface amount of the experimental sample using polyethylene as the base resin was 3.0 to 3.3 μg/cm ² .

It can be said that

<Insecticidal fast-acting test>
In the insecticidal fast-acting test, the German cockroach is continuously contacted with the experimental samples of Examples 1 to 32 and Comparative Examples 1 to 22, and the time taken until 50% of the German cockroach knocks down (KT-50) is measured. I went by. More specifically, from the experimental samples according to Examples 1 to 32 and Comparative Examples 1 to 22, a square piece having a side of 50 mm was cut out, and this was cut to a bottom of 55 mm in length, 55 mm in width, and 55 mm in height. Was installed on the inner bottom surface of the test container, and 10 German cockroaches were placed in the test container, and the time required for knocking down 5 German cockroaches was measured. The inner wall surface of the test container was coated with powder of calcium carbonate to prevent the German cockroach from escaping, and the German cockroach was continuously brought into contact with the experimental sample. As a result, the data shown in FIGS. 4 to 6 were obtained.

Further, from the data of FIGS. 4 to 6, for each of Examples 1 to 8, Examples 9 to 16, Examples 17 to 24, and Examples 25 to 32, data of KT-50 and paraffin for the molecular weight of paraffin oil were obtained.

Thus, KT-50 is improved over the small animal control resin composition and the small animal control resin molded product according to the comparative example. It is considered that this is because the low molecular weight paraffin oil having a molecular weight of about 330 to 530 easily enters the body through the body pores of the pest.

As is clear from FIG. 8, FIG. 10, FIG. 12, and FIG. 14, the tendency of change in KT-50 with respect to the kinematic viscosity of paraffin oil is almost the same regardless of the type of base resin, and the kinematic viscosity is 10 to 120 cSt. Within the range, KT-50 is improved as compared with the small animal control resin composition and the small animal control resin molded product according to the comparative example. It is considered that this is because the low-viscosity paraffin oil having a kinematic viscosity of about 10 to 120 cSt is easily transferred to the body surface of the pest.

<Pest repellent rate test>

Specifically, two shelters (60 mm in length, 60 mm in width, 60 mm in width, 60 mm in width, which can hide food and water and pests in a bottomed test container (300 mm in length, 230 mm in width, 250 mm in height) with an open top Height 10 mm) A and B were placed. Shelter A is assumed to have the experimental samples (squares with a side length of 50 mm) according to Examples 1 to 32 and Comparative Examples 1 to 22 installed therein, and shelter B does not have the experimental samples installed therein. I made it. 10 German cockroaches were placed in the test container and left for 10 hours, then shelters A and B were taken out from the test container, the number of German cockroaches in each shelter was counted, and the repellent rate [%] The repellent rate was calculated by the formula: {(number of insects in shelter B-number of insects in shelter A)/number of insects in shelter B}×100.

As shown in FIGS. 4 to 6, the experimental samples according to Examples 1 to 32 and Comparative Examples 1 to 22 all had a pest repellent rate of 100%. From this, it can be seen that the small animal control resin composition and the small animal control resin molded products according to Examples 1 to 32 not only exhibit a high pest repellency, but also exhibit high performance in terms of insecticidal rapid-acting. ..
