Embodiment 1

[0021] The components of this embodiment are as follows:

[0022]

[0023] The preparation method of the above-mentioned anti-rat PE material is as follows:

[0024] (1) First, the high-purity capsaicin (alkali) with a content of 95% nonanoic acid vanillic amide is pulverized into powder or granular form by a pulverizer, or the synthetic capsaicin (alkali) is heated to 40°C-100°C slowly Slowly melts into a liquid state;

[0025] (2) The high-purity synthetic capsaicin (alkali) of n-nonanoic acid vanillyl amide content 95% after pulverizing or melting is mixed together with PE matrix resin, antioxidant 1010, rheological agent, and PE wax;

[0026] (4) Finally, send the blended anti-rat PE raw material into the extrusion machine to obtain the anti-rat PE material.

Embodiment 2

[0028] The components of this embodiment are as follows:

[0029]

[0030] The preparation method of above-mentioned rodent-proof PE material is the same as embodiment 1

Embodiment 3

[0032] The components of this embodiment are as follows:

[0033]

[0034] The preparation method of the above-mentioned anti-rat PE material is as follows:

[0035] (1) earlier, the rat-repelling microcapsules with a content of 20% of nonanoic acid vanillylamide and the PE matrix resin are evenly blended;

[0036] (2) Continue to blend uniformly the PE matrix resin that antioxidant 1010, rheological agent, PE wax, and rodent-repelling microcapsules are mixed again;

[0037] (3) Finally, send the mixed anti-rat PE raw material into the extrusion machine to obtain the anti-rat PE material.

Abstract

The invention discloses a rat-proof PE (polyethylene) material and a preparation method. The components of the rat-proof PE material comprise PE base materials and rat-repelling materials. The rat-proof PE material is characterized in that content of n-vanillylnonanamide in the rat-repelling materials is 0.31%-0.89% of the total weight of the rat-proof PE material. According to the rat-proof PE material disclosed by the invention, the content of the n-vanillylnonanamide is effectively controlled within the minimal effective rat-repelling dosage range, and reasonable production cost is controlled, and therefore, the rat-proof PE material can be widely applied to producing various electric wires and cables, and large-popularization and promotion for rat-proof electric wires and cables becomes possible.

Description

technical field [0001] The invention relates to a rat-bite-proof PE plastic material and a preparation method thereof, in particular to a rat-bite-proof PE plastic material for electric wires and cables. Background technique [0002] According to incomplete statistics, 25% of all kinds of fires with unknown causes are caused by rats biting through the plastic sheath of cables. The research of adding it to various plastics as a rodent repellant has also had a certain history. However, the traditional purified capsaicin (alkali) (chemical name: vanillyl nonanamide) reaches 20,000 yuan per kilogram and is used as a rodent repellent, so that the cost of plastics is too high to be promoted, so it only stays in research stage. The price of synthetic capsaicin (base) (chemical name: n-nonanoic acid vanillic acid amide) on the market now is only below RMB 1600 per kilogram, which makes it possible for capsaicin (base) to be used as a rodent repellant in the production of plastic p...
