Embodiment 1

[0038] A slow-release rodent-proof and termite-proof cable sheathing material A, which contains 0.1% by weight of azadirachtin and 0.3% by weight of capsaicin, 0.1% by weight of magma fruit extract, and the balance is PE resin base material.

[0039] Its preparation method comprises the following steps:

[0040] 1) Grind the symphylla, place it in an ultrasonic cleaner, and extract it using ultrasonic-assisted extraction, using 95% ethanol as a solvent, the ratio of solid to liquid is 1:5.5, the ultrasonic power is 300W, and the extraction time is 40min; The supernatant is obtained after centrifugation in a high-speed centrifuge, the centrifugation speed is 3000r / min, and the centrifugation time is 20min; the supernatant is flash-evaporated at 65°C to 1 / 3 of the original volume, and magma fruit extract is thus obtained liquid.

[0041] 2) Use azadirachtin, capsaicin and the magma fruit extract obtained in step 1) to coat it with melamine resin to make microcapsules, and then ...

Embodiment 2

[0044] A slow-release anti-rodent and termite-proof cable sheathing material B, which contains 0.4% by weight of azadirachtin and 0.5% by weight of capsaicin, 0.3% by weight of magma fruit extract, and the balance is PE resin base material.

[0045] It is prepared according to the preparation method of Example 1.

Embodiment 3

[0047] A slow-release rodent-proof and termite-proof cable sheathing material C, which contains 0.25% by weight of azadirachtin and 0.4% by weight of capsaicin, 0.2% by weight of maggot extract, and the balance is PE resin base material.

[0048] It is prepared according to the preparation method of Example 1.

Abstract

The invention belongs to the field of cable sheath materials and specifically relates to a slow release type anti-rat and anti-ant cable sheath material. The slow release type anti-rat and anti-ant cable sheath material contains 0.1-0.4wt% of azadirachtin, 0.3-0.5wt% of capsaicine, 0.1-0.3wt% of common camptotheca fruit extracting solution and the balance of resin binder. The slow release type anti-rat and anti-ant cable sheath material is nontoxic and environment-friendly, is capable of effectively expelling instead of poisoning and killing white ants and rats, has the advantages of convenience in use and long-lasting effect, is prevented from being bitten by white ants and rats and is capable of achieving the purpose of protecting wires and cables.

Description

technical field [0001] The invention belongs to the field of cable sheathing materials, in particular to a slow-release rodent-proof and ant-proof cable sheathing material, a preparation method and application thereof. Background technique [0002] Plastic sheath materials such as polyvinyl chloride (PVC) and polyethylene (PE) in wires and cables are not only damaged by the environment such as oxygen, heat, light, force, and chemical erosion during use, but also by termites, mice, etc. Or the gnawing damage of organisms such as rabbits and mice, so that the service life of the sheath will be greatly reduced, and it will even cause power outages, fire accidents, communication, and signal interruptions, so that it will cause major losses to the national economy. Various fires occur in various countries every year, but according to statistics at home and abroad, 1 / 4 of the fires with unknown causes in cities are caused by rats biting off wires and cables, which shows that rats ...
