The adoption of sheath materials with different materials and different characteristics can lead the assembled cable assembly to have different characteristics in aspects of corrosion resistance, mechanical abrasion resistance, softness, bending degree and the like.
PE (polyethylene) belongs to thermoplastic plastics, and is widely used as an insulating sheath material of cables because of the advantages of excellent electrical insulation performance, good low-temperature performance, good chemical stability, small specific gravity and the like. Compared with MDPE (medium density polyethylene), LDPE (low density polyethylene) and LLDPE (linear low density polyethylene), the HDPE (high density polyethylene) material has the advantages that the molecular chain structure is regular, the molecular chain has a less branched chain structure, the branched chains are shorter, the molecular chains are orderly arranged, the inter-molecular chain distance is small, the inter-molecular chain acting force is large, the tensile strength of the material is high, the hardness is high, the wear resistance is excellent, the corrosion resistance is good, and the material is widely used as a cable sheath material, but the material has the problems of poor melt flowability and the flexibility.
At present, the flexibility of the material is improved mainly by adding EVA (ethylene-vinyl acetate copolymer) into the material, but the problem of poor compatibility of a matrix material exists, so that the mechanical property of the material is poor. In addition, EVA is a flammable material, which reduces the fire resistance of the material, so that the addition of EVA requires the addition of flame retardants, which include aluminum hydroxide, magnesium hydroxide, etc., which are highly polar substances and have poor compatibility with the matrix material, and thus the addition of flame retardants further results in poor system compatibility, resulting in serious mechanical properties of the material being damaged. Therefore, providing a corrosion-resistant cable sheath material with high mechanical strength and good flame retardance is a technical problem to be solved by the technicians in the field.

Comparative example 1
The only difference from example 1 is that the compatibilizer is 2-aminoethyl-2, 3-dihydroxypropyl-hydroxy phosphate.
Comparative example 2
The only difference from example 1 is that the compatibilizer is HDPE-g-MAH.
Comparative example 3
The only difference from example 1 is that no compatibilizing agent was added.
The corrosion-resistant cable sheath materials obtained in examples 1 to 8 and in the proportions 1 to 3 are added into an extrusion molding machine to be molded, sized, pulled and cut, and then the cable sheath is obtained.
Mechanical properties and flame retardant properties test: the cable jackets obtained in examples 1 to 8 and comparative examples 1 to 3 were tested for tensile strength and elongation at break according to the GB/T2951.11-2008 standard; oxygen index was tested according to GB/T2406.1-2008; the test results are recorded in table 1:
table 1 results of mechanical and flame retardant Properties test of Cable sheath
As can be seen from Table 1, the cable sheath materials provided by examples 1 to 8 of the invention have tensile strength of more than 16.4MPa, elongation at break of more than 260%, oxygen index of more than 36.1%, and excellent mechanical properties and flame retardance.
Comparative example 1 differs from example 1 only in that the compatibilizer is 2-aminoethyl-2, 3-dihydroxypropyl-hydroxy phosphate, and the flame retardancy of the cable material is improved, but the compatibility of the components between the base materials is poor, resulting in inferior mechanical properties of the cable material as compared with example 1.
Comparative example 2 differs from example 1 only in that the compatibilizer is HDPE-g-MAH, the flame retardancy of the resulting cable jacket material is greatly reduced compared to example 1, and the compatibility of the components between the cable jacket matrix materials is poor, and the compatibility of the flame retardant and the matrix materials is also poor, resulting in the mechanical properties of the cable being inferior to those of example 1.
Comparative example 3 differs from example 1 only in that no compatibilizing agent was added, and the mechanical properties and flame retardancy of the resulting cable sheathing material were inferior to those of example 1. In addition, after the mechanical property test results of the cable sheath materials obtained in comparative examples 1 to 3 and example 1 are compared, HDPE-g-MAH and 2-aminoethyl-2, 3-dihydroxypropyl-hydroxy phosphate are found to be used as compatilizers, and a synergistic effect exists between the HDPE-g-MAH and the 2-aminoethyl-2, 3-dihydroxypropyl-hydroxy phosphate, so that the mechanical property of the cable sheath materials is remarkably improved.
Corrosion resistance test: the cable jackets obtained in examples 1 to 3 were immersed in 45g/L oxalic acid solution and 40g/L sodium hydroxide solution, respectively, for 3d at 23.+ -. 2 ℃ for acid and alkali corrosion resistance testing, and the tensile strength change rate and elongation at break change rate were calculated, and the results are recorded in Table 2:
TABLE 2 acid and alkali Corrosion resistance test results
It can be seen from table 2 that the cable sheath provided by the invention has excellent acid and alkali corrosion resistance.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the invention.
