Embodiment 1

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

[0022]

[0023] The preparation method of above-mentioned anti-rat PVC 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) Stir the high-purity synthetic capsaicin (alkali) and plasticizer of n-nonanoic acid vanillylamide content 95% after crushing or melting in a high-speed mixer;

[0026] (3) The plasticizer and the PVC matrix resin, heat stabilizer, filler are blended again with the high-purity synthetic capsaicin (alkali) of n-nonanoic acid vanillic acid amide content 95% homogeneously, and mix homogeneously;

[0027] (4) Finally, send the blended anti-rat PVC raw material into the extruder to obtain the anti-rat PVC material.

Embodiment 2

[0029] The components of this embodiment are as follows:

[0030]

[0031] The preparation method of above-mentioned anti-rat PVC material is the same as embodiment 1

Embodiment 3

[0033] The components of this embodiment are as follows:

[0034]

[0035] The preparation method of above-mentioned anti-rat PVC material is as follows:

[0036] (1) earlier, the mouse-repelling microcapsules with 20% content of nonanoic acid vanillylamide and the PVC matrix resin are blended evenly;

[0037] (2) Continue to blend evenly with plasticizer, thermal stabilizer, filler, and the PVC matrix resin mixed homogeneously with the rodent-repelling microcapsules;

[0038] (3) Finally, send the mixed anti-rat PVC raw material into the extrusion machine to obtain the anti-rat PVC material.

Abstract

The invention discloses a rat-proof PVC (polyvinyl chloride) material and a preparation method thereof. The rat-proof PVC material comprises the following components: a PVC base material and a rat dispelling material. The rat-proof PVC material is characterized in that the content of nonivamide-pelargonic acid vanillylamide in the rat dispelling material is 0.31%-0.89% the total weight of the rat-proof PVC material. According to the rat-proof PVC material, the content of the nonivamide-pelargonic acid vanillylamide is controlled to be in a minimal dosage range for effective rat dispelling, and the production cost is controlled to be reasonable; the rat-proof PVC material can be widely applied to production of various wires and cables, and the popularization and generalization of a large quantity of rat-proof wires and cables is made possible.

Description

technical field [0001] The invention relates to a rat-biting-proof PVC plastic material and a preparation method thereof, in particular to a rat-biting-proof PVC 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 pla...
