PURPOSE:To prevent any rat-bite damage from occurring by micro-capsulizing a rat-repellent, making a genus of capsaicin an effective ingredient, and adding it to a rubber tube material. CONSTITUTION:A microcapsule agent made up as an effective ingredient after mixing one type or more than two types of capsaicins to be shown in a formula I, is added to rubber tube material, especially to composite rubber tube type outer layer resin 4. This effective ingredient value should be set to 1-2.0wt.%. In this connection, R in the formula I shows an alkyl group of carbon number 7-12, an alkinyl group and an alkenyl group. With this capsaicin micro- capsulized, any drop in resolution and dissipation in a working process is prevented from occurring while its pungent stimulus can be made so as not to give it to an operator, thus its handling becomes facilitated. |
