Abstract
The termite-proof cable has triple protection for termite, the first layer is outer sheath layer with termite repelling effect to prevent termite from destroying the cable, the second layer is armor layer with physical protection to avoid termite from destroying the cable, the third layer is inner sheath layer as the final barrier to prevent termite from entering the cable core. The outer sheath layer is positioned on the outermost layer of the cable, the outer sheath layer only drives the white ants, the inner sheath layer which has poisoning effect on the white ants is positioned on the outer surface of the inner sheath layer, and the armor layer and the outer sheath layer are arranged on the outer surface of the inner sheath layer, so that poisoning substances cannot be lost under normal conditions, and the environment cannot be polluted.
Description
Technical Field
The invention relates to the technical field of cables, in particular to a preparation method of a termite-proof cable.
Background
The wire and cable is used for transmitting electric (magnetic) energy, information and wire products for realizing electromagnetic energy conversion, the wire and cable in a broad sense is also called as a cable for short, and the cable in a narrow sense is an insulated cable. In modern society, the shadow of the wire and cable, such as the cloth wire and the broadband access wire used in families and hotels, can be seen everywhere; power cables, overhead cables, etc. laid by the power sector. The wire and cable have a very important position in national economy and social activities, and with the rapid development of economy, the wire and cable industry has become the second major industry in China.
Termites are one of three main hazards of damaging plastic cables and optical cables, cause many accidents every year and cause great economic loss, so that the research on the regenerated ratproof sheath material is very necessary. Toxic ant-proof agents and the like are added into the plastic material of the cable outer sheath in the prior art, mainly killing poison, and the ant-proof agents are easily lost to the external environment in the long-term use process due to the outer sheath of the cable, so that the environment is polluted.
Therefore, aiming at the defects in the prior art, the termite-proof cable preparation method and the preparation method thereof are provided to solve the defects in the prior art.
Disclosure of Invention
One of the purposes of the invention is to provide a preparation method of a termite-proof cable, which avoids the defects of the prior art. The preparation method of the termite-proof cable has excellent termite-proof effect and does not pollute the environment.
The above object of the present invention is achieved by the following technical measures:
the termite-proof cable is provided with a cable core, an insulating layer, an inner sheath layer prepared from a termite-resistant sheath material, an armor layer and an outer sheath layer prepared from a termite-resistant sheath material, wherein the cable core, the inner sheath layer, the armor layer and the outer sheath layer are sequentially arranged from the center to the outside.
Preferably, the ant-repelling sheathing material contains three-type PVC resin powder, dinonyl terephthalate, epoxidized soybean oil, polyethylene wax, a stabilizer, nano calcium carbonate, stearic acid, an impact modifier, an ant-repelling agent A and termite-proof microcapsules.
Preferably, the termite-proof inner sheath contains polyvinyl chloride with polymerization degree of 1600-2500, diisononyl phthalate, epoxidized soybean oil, polyethylene wax, stearic acid, nano calcium carbonate and a termite-killing agent.
Preferably, the content of the termite-proof microcapsule is termite-repelling agent B.

Detailed Description
The technical solution of the present invention is further illustrated by the following examples.
Example 1.
A preparation method of a termite-proof cable is provided with a cable core 100, an insulating layer 200, an inner sheath layer 300 made of a termite-resistant sheath material, an armor layer 400 and an outer sheath layer 500 made of a termite-resistant sheath material, wherein the cable core 100, the inner sheath layer 300, the armor layer 400 and the outer sheath layer 500 are sequentially arranged from the center to the outside, as shown in figure 1.
The ant-repelling sheathing material contains three types of PVC resin powder, dinonyl terephthalate, epoxidized soybean oil, polyethylene wax, a stabilizer, nano calcium carbonate, stearic acid, an impact modifier, an ant-repelling agent A and termite-proof microcapsules.
The termite-proof inner sheath contains polyvinyl chloride with polymerization degree of 1600-2500, diisononyl phthalate, epoxidized soybean oil, polyethylene wax, stearic acid, nano calcium carbonate and a termite-killing agent.
Wherein the content of the termite-proof microcapsule is termite-repelling agent B. The shell of the termite-proof microcapsule is phenolic resin. The ant repellent A is at least one of capsaicin, benzoin ester benzyl ester or chloro-formate. The ant repellent B is at least one of allyl isothiocyanate or fennel essential oil. The ant poisoning agent is abamectin and chlorfenapyr.
The termite-expelling agent A can emit strong pungent smell, thereby effectively preventing the damage of the termites to the termite-expelling agent A and prolonging the service life of the cable in the environment with the termites.
Because the efficacy of the termite-repellent agent A in the interior can be reduced after the termite-proof cable preparation method is placed for a long time. Therefore, the invention adds the termite-proof microcapsule and ensures the long-acting performance of termite prevention. When the rats and the ants bite, the termite-proof microcapsules are broken, so that the termite-repellent agent B in the termite-repellent microcapsules is released, and when the termites bite, formic acid generated by the termites reacts with nano calcium carbonate in the termite-repellent sheath material to generate gas dioxide so as to accelerate the release of the termite-repellent agent B, so that the termites are effectively repelled, and the further bite is prevented.
In an extreme case, if termites enter the inner sheath layer 300, the termites can be poisoned when the termites bite the termite poisoning agent, so that the cable core 100 is prevented from being damaged.
The phenolic resin is insoluble in contents, and the phenolic resin has high temperature resistance, so that the phenolic resin can stably exist in the heating process of a kneader or a granulator. The phenolic resin also has a flame retardant effect, so that even if the content of the phase change heat storage microcapsule has a combustible substance, the content cannot be easily combusted.

TABLE I Performance Table of test sample and comparative sample of the present invention
Among them, the termite protection effect test method was that the cable prepared from examples 3 to 6 and comparative example 1 was square-inserted into a termite bait wood and placed in a termite colony for 1 month. Observing the extent of damage (termite damage) to the cable placed in the colony by termite feeding, it is defined as excellent when the area of termite damage is 90% or more, medium when the area of termite damage is less than 90% and 50% or more, and poor when the area of termite damage is less than 50%.
As can be seen from table one, the termite protection effect of the cable prepared by the preparation method of the termite-proof cable obtained by the invention is excellent, and the termite protection effect of the cable without adding the termite-repellent agent a, the termite-proof microcapsule and the termite-poisoning agent is poor.
