The preparation cost of the cable master batch can be effectively controlled by mixing the polyvinyl chloride and the thermoplastic polyester elastomer, and meanwhile, the polyether soft segment and the uncrystallized polyester in the thermoplastic polyester elastomer form an amorphous phase, and the polyester hard segment partially forms a crystallized micro-region to play a role of a physical crosslinking point, so that the material does not need to be vulcanized in the forming process and is easier to process; the combination of the soft segment and the hard segment enables the cable master batch to have better processing performance and longer service life, and to have higher strength and flexibility. By adding the ultraviolet absorbent, the condition that the polyvinyl chloride can be degraded when being used in the sun for a long time is avoided, the cable master batch is prevented from aging, and the service life of the material is prolonged. By adding the antioxidant, the polyvinyl chloride can be prevented from being oxidized, and the service life of the polyvinyl chloride is prolonged. By adding the plasticizer, the fillers can be better mixed, the processability of the master batch is enhanced, and the polyvinyl chloride and the thermoplastic polyester elastomer can be better mixed together.

Because the boron nitride nanosheets are inorganic particles and have poor compatibility with the polymer master batch, the boron nitride nanosheets can be uniformly dispersed in the polymer master batch without causing polymerization after surface treatment of the sodium dodecyl sulfate. The low friction coefficient u of boron nitride is 0.16, the boron nitride does not increase at high temperature, and simultaneously has high strength and toughness, and the wear resistance of the material is enhanced by mixing the modified boron nitride nanosheet with polyvinyl chloride and thermoplastic polyester elastomer.

Example 1:
1. preparation of samples
The first step is as follows: BNN and SDS are placed in a ball milling tank, wherein the addition amount of BNN is 15g, the addition amount of SDS is 5g, the ball milling time is 8h, and the rotating speed of the ball mill is 400 rad/min.

Comparative example 1, comparative example 2, and comparative example 3:
the methods for preparing samples of comparative examples 1, 2 and 3 are substantially the same as the method for preparing the sample of example 1, and are not repeated herein, except that:
the BNN added in comparative example 1 was untreated BNN;
the amount of BNNs added in comparative example 2 was 10 wt%;
BNN not added in comparative example 3.
Characterization and testing
In order to make the experimental data more convincing before the test, the master batch needs to be prepared into sample strips of the same size and subjected to a scratch resistance test by a five-finger scratch method with the measurement standard being GMW 3943.
Comparison and analysis of test results
The scratch resistance test was performed on example 1 and comparative example 1, and comparative example 2 and comparative example 3, the sample had a diameter of 16mm and a thickness of 1mm, and after the test was completed, it was required to visually inspect the scratch in a well-lighted environment, usually bright north sky sunlight or a standard light source of D65, and the scratch line could be presented at the most clearly visible angle by changing the angle of the sample from the observer. The range of 10% of each of the starting point and the end point of the scratch was excluded at the time of evaluation, that is, only the range of 80% of the middle portion was taken as an effective evaluation area. The test results show in table 1, which shows that the scratch mark of example 1 is compared with the scratch marks of the other three groups. It was observed that in comparative example 2, the amount of BNNs added was 10 wt% and the scoring was about 80% of example 1 as compared with example 1, but in comparative example 2, the amount of BNNs added was twice as much as that in example 1, and thus example 1 was more advantageous than comparative example 2. The reasons for the scratches of comparative examples 1 and 3 were different from those of comparative example 1, and the untreated BNN added in comparative example 1 had a thick sheet layer and poor compatibility with the polymer, and caused agglomeration, which resulted in poor scratch resistance. In comparative example 3, no scratch-resistant BNN, which is a pure polymer material, was added, was softer in texture and therefore much less scratch-resistant than in example 1.

Comparative example 4 and comparative example 5:
comparative examples 4 and 5 the method for preparing samples was substantially the same as that of example 1, and no further description is given here, except that:
the masterbatch used in comparative example 4 was PVC, containing no TPEE;
the masterbatch used in comparative example 5 was TPEE, containing no PVC.
Characterization and testing
In order to make the experimental data more convincing before the test, the samples of example 1, comparative examples 4, 5, respectively, were placed in a thermostatic oven, the temperature of which was set to 80 ℃ for accelerated ageing, and the change in colour was observed. And simultaneously, carrying out scratch resistance tests on the samples of the three groups of materials, which are the same as the above and are not described in detail herein.
Comparison and analysis of test results
Example 1 differs from comparative examples 4 and 5 in the choice of master batch, which has a base price of 12235.56 yuan/ton in the last year according to the current market quoted PVC, whereas the TPPE manufactured by DuPont in the United states under the trade name Hytrel 3078FG has a price of 22000 yuan/ton, with PVC prevailing in terms of price. The influence of the selection of different masterbatches on the linear performance of the cable is judged by testing the weather resistance and scratch resistance of three samples, in table 1, the sample of example 1 is baked in an oven at a constant temperature of 80 ℃ for 150h, taken out and observed for color change, then the samples of comparative examples 4 and 5 are respectively placed in the oven, and the color of the sample is changed to be the same as the color of the sample baked in example 1 according to how long the sample needs to be used. It was observed that comparative example 4 took 74h, while comparative example 5 took 235 h. Meanwhile, the scratch resistance of comparative example 5 was the best as compared with the scratch. But embodiment 1 is still selected as the best embodiment for the sake of comprehensive cost.

Comparative example 4 74h 3
Comparative example 5 235h 0.7
In conclusion, the preparation cost of the cable master batch can be effectively controlled by mixing the polyvinyl chloride and the thermoplastic polyester elastomer, meanwhile, the polyether soft segment and the uncrystallized polyester in the thermoplastic polyester elastomer form an amorphous phase, and the polyester hard segment partially forms a crystalline micro-region which plays a role of a physical crosslinking point, so that the material is free from vulcanization in the forming process and is easier to process; the combination of the soft segment and the hard segment enables the cable master batch to have better processing performance and longer service life, and to have higher strength and flexibility. By adding the ultraviolet absorbent, the condition that the polyvinyl chloride can be degraded after being used in the sun for a long time is avoided, the cable master batch is prevented from aging, and the service life of the material is prolonged. By adding the antioxidant, the polyvinyl chloride can be prevented from being oxidized, and the service life of the polyvinyl chloride is prolonged. By adding the plasticizer, the fillers can be better mixed, the processability of the master batch is enhanced, and the polyvinyl chloride and the thermoplastic polyester elastomer can be better mixed together. When the modified boron nitride nanosheet is prepared, the boron nitride nanosheet is inorganic particles, so that the boron nitride nanosheet is poor in compatibility with the polymer master batch, and can be uniformly dispersed in the polymer master batch without causing polymerization after being subjected to surface treatment by sodium dodecyl sulfate.
The above description is only for the preferred embodiment of the present invention and is not intended to limit the present invention, so that any modifications, equivalents, improvements, etc. made to the above embodiment according to the present invention are within the scope of the present invention.
