2.2 The surface of the cable sheath is microscopically uneven by carrying out plasma spraying treatment on the cable sheath, so that the binding force between the antistatic coating and the surface of the cable sheath is improved, and the antistatic coating can be better coated on the surface of the cable sheath; the master batch of the cable sheath is polyolefin thermoplastic elastomer (TPO);
3) Coating antistatic coating on the surface of the outer skin of the cable to obtain an antistatic cable; the coating mode in the embodiment adopts high-temperature spraying; in practical operation, the coating mode can also be liquid phase spraying or dipping coating.
The hyperbranched polymethyl methacrylate is a highly branched three-dimensional macromolecule, has rich tail ends, has good compatibility with PVDF, can strip, disperse and surface-modify inorganic nano materials, enables the inorganic nano materials to be better dissolved in a matrix, and utilizes the characteristic of the hyperbranched polymethyl methacrylate to enable the carbon nano tubes to be uniformly and stably dispersed in the PVDF by mixing the carbon nano tubes with the hyperbranched polymethyl methacrylate, so that good conductivity can be achieved by selecting a small amount of carbon nano tubes, and the antistatic performance of a cable is improved.
Comparative example 1, comparative example 2, comparative example 3, comparative example 4:
the preparation methods of comparative examples 1, 2, 3 and 4 are substantially the same as those of example 1, and are not described herein, except that:
comparative example 1 was not added with carbon nanotubes;
the amount of carbon nanotubes added in comparative example 2 was 0.1wt%;
the amount of carbon nanotubes added in comparative example 3 was 0.3wt%;
the amount of carbon nanotubes added in comparative example 4 was 3wt%.
Characterization and testing
In order to make experimental data more convincing before testing, the conductive performance of the antistatic coating needs to be tested, samples of example 1 and comparative examples 1-4 are prepared according to the preparation method, the quality and coating thickness of each sample are consistent, four probes are used for measuring the surface resistance after cooling, each group is measured for 20 times, and an average value is obtained. (measurement standard is GB/T1410-2006)
Comparison and analysis of test results
The surface resistance of the material is lower than 10 6 Omega/sq was regarded as antistatic, and it was found from the observation of Table I that the surface resistance of example 1 and comparative example 4 were both lower than 10 6 Omega/sq and the lowest surface resistance in comparative example 4, but comparative example 4 had a black coating color compared to example 1, limiting the use of the coating, and the 3% carbon nanotube addition made the coating itself more expensive, so example 1 was better. In contrast to comparative example 1, which had a poor conductivity because the dispersed carbon nanotubes did not form a conductive network in PVDF, the carbon nanotubes in example 1 formed a stable conductive network in the substrate, and the carbon nanotubes in the coating reached a threshold permeation value at a carbon nanotube content of 0.5wt% in comparison with example 1, so that example 1 was better in effect and a good antistatic property was obtained for the cable.
Table one: conductive property of antistatic coating with different carbon nano tube additive contents
Comparative example 5:
comparative example 5: the preparation method of the antistatic cable is substantially the same as that of embodiment 1, and is not described herein, except that:
in comparative example 5 hyperbranched polymethyl methacrylate was not added.
Characterization and testing
In order to make the experimental data more convincing before testing, the coatings of example 1 and comparative example 5 need to be tested for conductivity. The specific method is the same as that mentioned above, and will not be described here again.
Comparison and analysis of test results
Example 1 and comparative example 5 differ in the presence or absence of the addition of hyperbranched polymethyl methacrylate. As shown in table two, the hyperbranched polymethyl methacrylate component added in example 1 provided that the carbon nanotubes were added in the same amount to give a better conductive effect. As shown in fig. 2 and 3, the present invention can disperse the carbon nanotubes by adding the hyperbranched polymethyl methacrylate, so that the carbon nanotubes are not entangled, and thus the carbon nanotubes can achieve the optimal conductive effect in a smaller amount. The hyperbranched polymethyl methacrylate can have good compatibility with PVDF, and the carbon nano tube is used as an inorganic nano filler, so that the carbon nano tube has poor compatibility with PVDF and is easy to generate interface effect and agglomeration, but the surface of the carbon nano tube treated by the hyperbranched polymethyl methacrylate is adhered with a plurality of hyperbranched polymethyl methacrylates, so that the carbon nano tube can be better compatible in PVDF and further has better conductive performance.
And (II) table: influence of the presence or absence of hyperbranched polymethyl methacrylate on the conductive properties of the coating
The invention has the following advantages:
(1) According to the invention, the modified PVDF coating is coated on the surface of a cable taking polyolefin thermoplastic elastomer (TPO) as a master batch in a high-temperature spraying manner, so that the surface of the cable has antistatic performance.
(2) In the PVDF coating, hyperbranched polymethyl methacrylate can effectively strip and disperse the carbon nanotubes in a liquid phase, meanwhile, the compatibility of the hyperbranched polymethyl methacrylate and the PVDF coating is good, the carbon nanotubes can be promoted to be uniformly and stably dispersed in the PVDF, the agglomeration phenomenon can not occur, and further, the good conductivity can be achieved by the small carbon nanotube addition.
(3) The PVDF coating has the advantages of high strength and high toughness under low temperature, friction resistance, corrosion resistance, high dielectric constant, ultraviolet resistance, good radiation resistance and the like, is low in processing temperature, good in melt fluidity, extremely suitable for spraying in a high-temperature spraying mode, and capable of being automatically extinguished when in high temperature, and has antistatic capability after being added with the modified carbon nano tube, so that the PVDF coating can be applied in wider fields.
(4) The carbon nano tube can be uniformly dispersed in the PVDF substrate, so that the conductive performance of the PVDF substrate is enhanced, and the toughening effect is achieved, and the service life of the coating is longer.
(5) The combination of the cable and the PVDF coating is very firm, and the condition of uneven interface energy can not occur, because the cable is subjected to ion spraying treatment before spraying, the surface of the cable becomes rough in a microscopic degree, and the combination capacity with the PVDF coating is stronger on the original basis.
The foregoing description is only a preferred embodiment of the present invention, and is not intended to limit the present invention, so any modifications, equivalents, improvements, etc. of the above embodiments according to the present invention are still within the scope of the present invention.
