Embodiment 1

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

[0022]

[0023] High-purity synthetic capsaicin (base) with 95% n-nonanoic acid vanillyl amide content 1.2

[0024] The preparation method of the above-mentioned rodent-proof low-smoke and halogen-free material is as follows:

[0025] (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;

[0026] (2) Stir the high-purity synthetic capsaicin (alkali) and magnesium hydroxide of the pulverized or melted n-nonanoic acid vanillylamide content 95% in a high-speed mixer;

[0027] (3) magnesium hydroxide and linear low density polyethylene, maleic anhydride grafted ethylene-octene copolymer, ethylene -Acrylic acid copolymer, silicone, and antioxidant 1010 are blended together and mixed evenly;

[0028] (4) Finally, send...

Embodiment 2

[0030] The components of this embodiment are as follows:

[0031]

[0032] The preparation method of the above-mentioned rodent-proof low-smoke and halogen-free material is the same as in Example 1

Embodiment 3

[0034] The components of this embodiment are as follows:

[0035]

[0036]

[0037] The preparation method of the above-mentioned rodent-proof low-smoke and halogen-free material is as follows:

[0038] (1) earlier, the rodent-repelling microcapsules with 20% nonanoic acid vanillyl amide content, linear low-density polyethylene, maleic anhydride grafted ethylene-octene copolymer, and ethylene-acrylic acid copolymer are evenly blended;

[0039] (2) Add organosilicon, antioxidant 1010, and magnesium hydroxide to the low-smoke, halogen-free matrix resin that is uniformly mixed with the rodent-repelling microcapsules and continue to blend evenly;

[0040] (3) Finally, send the mixed rodent-proof low-smoke and halogen-free raw materials into an extrusion machine to obtain rodent-proof low-smoke and halogen-free materials.

Abstract

The present invention discloses a rodent-proof low smoke zero halogen material and method for preparation thereof; the components comprise a low smoke no halogen base material and a rodent-repelling material; the N-vanillylnonanamide content in the rodent-repelling material is 0.31-0.89% of the total weight of the rodent-proof low smoke zero halogen material. In the rodent-proof low smoke zero halogen material of the present invention, the N-vanillylnonanamide content is kept to the smallest possible range of amounts, and production costs are controlled and reasonable; the invention can be widely applied to the production of various types of electrical wire and cable, and enables large-scale widespread popularization of rodent-bite-protected wires and cables.

Description

technical field [0001] The invention relates to a rodent-proof low-smoke halogen-free plastic material and a preparation method thereof, in particular to a rodent-proof low-smoke halogen-free 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 repe...
