Description
Technical Field
The invention belongs to the field of preparation of tinned conductor materials, and relates to an ultrahigh tensile alloy tinned copper conductor material.
Background
The cable usually wraps the wires with an insulating outer layer after interaction, and has good mechanical toughness as the service working temperature of the polytetrafluoroethylene reaches 250 ℃; even if the temperature is reduced to-196 ℃, the elongation of 5 percent can be kept, and the polytetrafluoroethylene has the advantages of inertia, strong acid and alkali resistance, water and various organic solvents resistance to most chemicals and solvents, high electrical insulation property and 1500-volt high-voltage resistance, so that the polytetrafluoroethylene is widely applied to cable protective casings, but the industrial application of the polytetrafluoroethylene is limited due to the outstanding non-adhesiveness of the polytetrafluoroethylene. It is an excellent anti-sticking material, and this property makes it extremely difficult to adhere it to the surface of other objects, and therefore, when it is used as a coating layer, it is liable to cause a slip phenomenon, which in turn causes the inner wire to slip out.
The patent application number of CN201510195485.9 discloses an ultrahigh tensile alloy tin-plated copper conductor material, which comprises a plurality of tin-plated copper conductors, wherein the plurality of tin-plated copper conductors are respectively extruded and wrapped with a first plastic insulating layer and then are twisted, and the twisted plurality of tin-plated copper conductors are wrapped with a polyfluoroethylene inner wrapping tape and a second plastic insulating layer; and a water-blocking yarn filling layer or a water-blocking belt layer or a hot melt adhesive layer is arranged between the outer surfaces of the stranded plurality of tin-plated copper conductors and the inner surface of the polyfluortetraethylene inner bag. However, the temperature of the cable is high in the using process, so that the performance change of the hot melt adhesive is easily caused, and the adhesion performance of the hot melt adhesive is further influenced, and meanwhile, although the tinned copper conductor of the inner layer has high tensile resistance, the plastic insulating layer wrapped outside the tinned copper conductor needs to consider the insulating high-temperature resistance and the tensile resistance, but the plastic layer has low tensile resistance under the condition of ensuring high-temperature resistance.

Example 1:
the specific preparation process of the high tensile rubber is as follows:
step 1: simultaneously adding 1kg of carbon nano tube and 5.5L of mixed acid solvent into an ultrasonic reaction container for ultrasonic dispersion for 30-40min, then heating to 90-100 ℃ for reflux reaction for 3-4h, and then filtering, washing and drying to obtain the carboxylated carbon nano tube, wherein the mixed acid is concentrated sulfuric acid and concentrated hydrochloric acid according to the weight ratio of 1: 3, mixing and preparing;

| Tear Strength (kN/m) | 1.92 | 1.53 | 1.77 |
As can be seen from table 1, the high tensile rubber prepared in example 1 has higher tensile strength, since the polymeric monomer used in the preparation process of the high tensile rubber is a polymer formed by the interaction between terminal hydroxyl groups of terminal dihydroxy siloxane oxidized carbon nanotubes, and further, a large number of carbon nanotubes are alternately connected and fixed on the prepared polymer skeleton, and the polymer prepared by the polymeric monomer through the polymerization reaction of toluene diisocyanate has higher tensile strength, the rubber material prepared in example 2 by directly crosslinking the hydroxy polydimethylsiloxane and the toluene diisocyanate has lower tensile strength, and meanwhile, the carbon nanotubes are directly added in the crosslinking process of the hydroxy polydimethylsiloxane and the toluene diisocyanate by physical mixing in example 3, because the acting force between the carbon nanotubes and the crosslinked polymer is smaller, further, the carbon nanotubes are not uniformly dispersed in the goods, so that the mechanical property of the polymer is easily affected, and the mechanical property of the prepared rubber material is low.
Example 4:
the specific preparation process of the high-temperature resistant adhesive is as follows: weighing 100g of polyvinyl alcohol, adding 260g of hot water at 95-100 ℃, stirring and dissolving to obtain a polyvinyl alcohol aqueous solution, simultaneously weighing 30g of hydroxy polydimethylsiloxane, adding 255g of acetone solution, stirring and mixing to obtain a hydroxy polydimethylsiloxane solution, simultaneously adding the two solutions into a reaction kettle, dropwise adding 32g of isophorone diisocyanate while stirring, violently stirring while dropwise adding, and after completely dropwise adding, stirring at constant temperature for reaction for 30-40min to obtain viscous colloid, namely the high-temperature resistant adhesive.
Example 5:
the specific preparation process of the high-temperature resistant adhesive is as follows: weighing 100g of polyvinyl alcohol, adding 260g of hot water at 95-100 ℃, stirring and dissolving to obtain a polyvinyl alcohol aqueous solution, simultaneously weighing 30g of hydroxy polydimethylsiloxane, adding 255g of acetone solution, stirring and mixing to obtain a hydroxy polydimethylsiloxane solution, simultaneously adding the two solutions into a reaction kettle, dropwise adding 32g of isophorone diisocyanate while stirring, violently stirring while dropwise adding, and after completely dropwise adding, stirring at constant temperature for reaction for 30-40min to obtain viscous colloid, namely the high-temperature resistant adhesive.
