preparation example 1

[0084] A kind of Rosin extract, is made by following method:

[0085] Step 1: raise the temperature of 1 kg of rosin to 100°C, keep the temperature for 10 minutes, filter while it is hot, keep the upper solution, after it cools down, add 1.2 times the volume of turpentine than the upper solution, stir evenly, and obtain the first mixture;

[0086] Step 2: Mix the first mixture, methyl carbamate and sulfated castor oil, and stir for 20 minutes to obtain the second mixture, wherein the quality of methyl carbamate is 5% of the first mixture, and the quality of sulfated castor oil is the second 10% of a mixture;

[0087] Step 3: add the second mixture into acidic ethanol to reflux, crystallize after extraction, and wash to obtain rosin extract.

preparation example 2

[0089] A kind of Rosin extract, is made by following method:

[0090] Step 1: raise the temperature of 1 kg of rosin to 120°C, keep the temperature for 15 minutes, filter while it is hot, keep the upper solution, after it cools down, add 0.8 times the volume of turpentine than the upper solution, and stir evenly to obtain the first mixture;

[0091] Step 2: Mix the first mixture, methyl carbamate and sulfated castor oil, and stir for 10 minutes to obtain the second mixture, wherein the quality of methyl carbamate is 2% of the first mixture, and the quality of sulfated castor oil is the second 15% of a mixture;

[0092] Step 3: add the second mixture into acidic ethanol to reflux, crystallize after extraction, and wash to obtain rosin extract.

preparation example 3

[0094] A kind of Rosin extract, is made by following method:

[0095] Step 1: raise the temperature of 1 kg of rosin to 115° C., maintain the temperature for 12 minutes, filter while it is hot, and keep the upper layer solution. After it is cooled, add turpentine whose volume is equal to that of the upper layer solution, and stir evenly to obtain the first mixture;

[0096] Step 2: Mix the first mixture, methyl carbamate and sulfated castor oil, and stir for 15 minutes to obtain the second mixture, wherein the quality of methyl carbamate is 3% of the first mixture, and the quality of sulfated castor oil is the second 12% of a mixture;

[0097] Step 3: add the second mixture into acidic ethanol to reflux, crystallize after extraction, and wash to obtain rosin extract.

Abstract

The invention relates to the field of cables, and particularly discloses a termite-proof cable and a preparation method thereof. The termite-proof cable comprises a core layer and a sheath, the sheathis prepared from polyvinyl chloride, polyethylene, polyamide fibers, a dispersing agent, an antioxidant and an anti-termite agent, the anti-termite agent comprises a rosin extract, bifenthrin and capsaicine, and methyl carbamate and sulfated castor oil are added into the rosin extract for modified extraction in the extraction process. The preparation method of the termite-proof cable comprises the following steps of: firstly preparing a core layer, and then mixing, heating and extruding the raw materials of a sheath, so that the sheath wraps the outer side of the core layer to form the termite-proof cable. The termite-proof cable provided by the invention has relatively good termite-proof performance and relatively good mechanical properties.

Description

technical field [0001] The present application relates to the field of cables, and more specifically, it relates to a termite-resistant cable and a preparation method thereof. Background technique [0002] A cable is a wire that transmits power or information from one place to another and is used to connect circuits, appliances, etc. Among them, cables can be divided into power cables, control cables, compensation cables, shielded cables, high temperature cables, computer cables, signal cables, coaxial cables, fire-resistant cables, marine cables, mining cables, aluminum alloy cables, etc., the application of cables more extensive. [0003] The current cable includes a core layer and a sheath, the core layer is made of conductive material, and the sheath is wrapped outside the core layer and made of non-conductive material. Generally, the sheath is made of polyvinyl chloride. [0004] In view of the above-mentioned related technologies, the inventor believes that during t...
