いては環境問題もあって疑問視されるようになった。2. Description of the Related Art Various pesticides have been sold and used to protect various products from harmful insects, protect their longevity, function and safety, and to lead a more comfortable civilized life. The indiscriminate eradication of insects by using agents has been questioned due to environmental problems.

を持続させるのが重要である。However, there is a problem in what form of such insect repellents should be commercialized to have good insect repellent and repellent effects and to be safer and more convenient. In particular, sustainability is important in terms of insect repellent and repellent effects. For this purpose, it is important to temporarily release a small amount of the drug effect and gradually release a small amount to maintain the drug effect.

であった。However, the above method (1) requires a container and requires a troublesome explanation for safe handling, and the method (2) requires a volume. The range that can be used was limited due to the space occupied. Further, in the method (3), although paper, pulp, cotton, non-woven fabric, etc. are used as the carrier, the volatilization of both water-based and oil-based materials is rapid and unsatisfactory. In accordance with the above, an attempt was made to carry an insect repellent on the silica gel, but there was a limit to the amount that could be carried, and volatilization could not be sustained. In addition, it is difficult to shape these carriers, and even if they can be shaped, they can only have a specific shape such as a flat shape, and if they are made into shapes other than this, it will be very costly and inconvenient.

く、この点からも防虫忌避剤の揮散を妨げない。The shaping of the mixture of the polyethylene powder particles and the insect repellent is carried out by a method such as injection molding, compression molding, extrusion molding by melt-kneading the silicon dioxide carrying the insect repellent and the resin. Although it is possible, the resin covers the silicon dioxide and the volatilization of the drug is significantly hindered. In order to avoid such a state, it is most preferable to mix resin powder particles and silicon dioxide carrying an insect repellent and sinter. That is, since the sintered body has continuous pores, the insect repellent present inside is also present in a volatile state. Furthermore, since the insect repellent is present around the outer periphery of the resin powder particles, the insect repellent is not buried inside the resin, and in this respect as well, volatilization of the insect repellent is not hindered.

It is preferably m 3 or more and 0.8 g / cm 3 or less. When the apparent density of the sintered compact is less than 0.2 g / cm 3 , the fusion surface of the polyethylene powder is reduced and the strength of the compact becomes weak. If the apparent density exceeds 0.8 g / cm 3 , volatilization of the insect repellent inside is hindered, which is not preferable.

酸化ケイ素に担持された防虫忌避剤はその薬効が徐々に
揮散され、その薬効を長持ちさせることができる。As described above, since the insect repellent material of the present invention is characterized in that silicon dioxide carrying an insect repellent is mixed with polyethylene resin powder particles and sintered and molded, it is supported on silicon dioxide. Insect repellents, whose medicinal effect is gradually volatilized, can prolong the medicinal effect.

揮散効果を妨げない利点がある。Moreover, since the polyethylene resin powder particles mixed with silicon dioxide carrying the above-mentioned insect repellent are sintered and formed, a myriad of air passages communicating from one surface of the base material to the other surface are formed. Therefore, there is an advantage that the resin itself does not interfere with the volatilization effect of the insect repellent.
