Abstract

The invention discloses a capsicin rat-proof agent used for cables in a ship and a preparation method of same. The capsicin rat-proof agent is mainly composed of a microcapsule core material and a microcapsule wall material coating the exterior thereof. The preparation method includes the steps of: S1) preparing a water emulsion of the microcapsule core material; S2) preparing hydrosol of the microcapsule wall material; S3) preparing the microcapsule rat-proof agent. The microcapsule core material comprises, by weight, 1-30% of nonivamide, 0.5-15% of cyclic imide, 10-90% of castor oil, 0.1-5%of hydrophobic organo-siloxane, and 1-50% of a surfactant. In the invention, the capsicin is coated with a high-molecular material so as to produce the microcapsule rat-proof agent. Due to isolation by the high-molecular material, oxidization and dampness absorbing hydrolysis of the capsicin are avoided. The rat-proof agent is long in rat-proof effect time and can durably prevent the cables in a ship from rat biting.

Description

technical field [0001] The invention relates to the technical field of cable rodent repellent, in particular to a capsaicin rodent repellent for ship cables and a preparation method thereof. Background technique [0002] Due to the small space on the ship, many mechanical equipment, electrical instruments, and high density of cables, the ship is sailing at sea for a long time, and maintenance is very inconvenient. When ocean-going cargo ships are loading and unloading, it is easy to mix rats with the cargo and bring them on board. Rats often gnaw on cables in order to grind their teeth, short-circuiting of wires caused by rats, and failure of instruments and meters often occur. [0003] N-nonanoic acid vanillylamide is a synthetic capsaicin, referred to as capsaicin, and its spiciness is dozens of times hotter than the hottest pepper. If capsaicin is applied on the surface of the cable, mice will not dare to approach it, which has a strong anti-gnawing effect. Vanillyl no...
