Description
Technical Field
The application relates to the field of cable insulation protection materials, in particular to an anti-aging insulation protection material for coaxial cables and a preparation method thereof.
Background
Coaxial cable is a wire and signal transmission line, generally made of four layers of materials: the innermost part is a conductive copper wire, the periphery of the conductive copper wire is covered with a plastic insulator, a thin net-shaped conductor is arranged outside the insulator, and then an insulating protection layer made of insulating materials is covered outside the conductor. Polyvinyl chloride (PVC) is a commonly used insulating material, and PVC has good electrical insulating properties and mechanical strength, and has low cost and easy workability, and thus is widely used in the manufacture of insulating protective layers for coaxial cables, etc.
Because coaxial cables are widely used in the fields of cable television networks, television broadcast transmissions, wireless communication base stations, security monitoring systems, data communication networks, and the like, coaxial cables are often exposed to sunlight for a long time. In the ultraviolet wavelength range, PVC dechlorination can be aggravated, the PVC material is aged, macroscopic appearance is that the insulating protective material of the cable is hardened and catalyzed, so that the cable is easy to damage under the action of external force of the insulating protective material of the cable, and the insulating protective effect on the cable core is lost.
At present, anti-aging auxiliary agents such as a light shielding agent, an ultraviolet light absorber and the like are usually added into PVC, and the light shielding agent reduces the effect of ultraviolet light on the inside of a PVC matrix through the effect of physical shielding; the ultraviolet light absorber can selectively absorb and convert the ultraviolet light irradiated into the matrix preferentially, and the effect of the ultraviolet light on the PVC matrix is reduced. But sun exposure leads to the cable to receive ultraviolet irradiation, can also make the environment temperature that the cable was located too high, and leads to the cable to lead to the insulating layer to accelerate ageing because of the high temperature, and makes the cable material become brittle, lose elasticity, and the risk of rupture and fracture increases, reduces cable life.
Disclosure of Invention
In order to prolong the service life of the cable, the application provides an anti-aging insulating protective material for a coaxial cable and a preparation method thereof.
The anti-aging insulating protective material for the coaxial cable adopts the following technical scheme:
an anti-aging insulating protective material for coaxial cables comprises the following components in parts by weight:
88-94 parts of polyvinyl chloride resin, 38-44 parts of polyimide resin, 10-15 parts of thermal stability enhancer, 18-22 parts of calcium-zinc composite heat stabilizer, 2-4 parts of binding synergist, 5-10 parts of benzophenone ultraviolet light absorber, 2-4 parts of antioxidant, 6-8 parts of anti-aging nano material, 10-14 parts of shock resistant fiber filler, 3-5 parts of flame retardant, 1-2 parts of carbon black and 1-2 parts of zinc glycerate; the thermal stability enhancer comprises salicylic acid rare earth-silicon dioxide aerogel and N-substituted phenyl-coated maleimide derivatives.
By adopting the technical scheme, the polyvinyl chloride resin has good electrical insulation performance and mechanical strength, but has poor resistance to heat and flame; the polyimide resin has the characteristics of high heat resistance, high mechanical strength, low density, high thermal stability and the like, but the polyimide resin has high price, and the polyvinyl chloride resin and the polyimide resin are compounded according to the content, so that the heat resistance of the cable insulation protection layer can be improved, and meanwhile, the cable can keep the characteristics of light weight and softness.
The silica aerogel has better heat resistance, but because the silica aerogel particles are tiny and have high surface energy, the phenomenon that nano holes collapse and particle diameters of particles grow up easily occurs at high temperature is caused, so the heat resistance degree of the silica aerogel is limited, however, the heat resistance of the salicylic acid rare earth-silica aerogel and the salicylic acid rare earth form a complex, the heat resistance of the silica aerogel can be improved by 200-400 ℃, the heat resistance stability of the cable is greatly improved, the cable is not easy to crack under some extreme environments, such as fire disaster, the insulating protection layer of the cable is reduced to crack under some extreme environments, the cable core is exposed, the possibility of larger accidents is caused, and the use safety of the cable is improved. And when the N-substituted phenyl-coated maleimide derivative and the rare earth salicylate-silica aerogel are mixed and then added into the polyvinyl chloride resin, the N-substituted phenyl-coated maleimide derivative and the rare earth salicylate-silica aerogel can act synergistically, so that the dechlorination rate of the polyvinyl chloride resin is slowed down, and the ageing resistance of the cable insulation protection layer is improved.
The calcium-zinc composite heat stabilizer is a metal soap heat stabilizer, is nontoxic, has better transparency and lubricity, is suitable for being used as a heat stabilizer of soft PVC products such as cables, is compounded with a heat stability enhancer, and can remarkably improve the heat resistance of the cable insulation protection layer and simultaneously ensure that the cables keep the characteristics of light weight and softness. However, because of poor association between calcium and zinc salts, the calcium and zinc composite heat stabilizer needs to be compounded with a combination synergist, so that the calcium and zinc composite heat stabilizer can maintain relatively stable heat resistance and stability.
The benzophenone ultraviolet light absorber preferentially absorbs and converts ultraviolet light irradiated into the matrix, and the benzophenone ultraviolet light absorber and the light shielding agents such as carbon black, zinc glycerolate and the like perform synergistic action, so that the action of the ultraviolet light on the polyvinyl chloride resin matrix can be reduced; meanwhile, the benzophenone ultraviolet light absorber is mixed with organic calcium (namely calcium-zinc composite heat stabilizer) for use, so that the photo-aging of the polyvinyl chloride resin can be inhibited.
The heat resistance of the cable insulation protection layer can be improved basically through the synergistic effect of the polyvinyl chloride resin and the polyimide resin, and the heat resistance stability of the cable is further improved greatly through the synergistic effect of the salicylic acid rare earth-silicon dioxide aerogel and the calcium-zinc composite heat stabilizer in the heat stability enhancer; meanwhile, the anti-aging performance of the cable insulation protective layer can be obviously improved through the synergistic effect of the N-substituted phenyl-coated maleimide derivative and the salicylic acid rare earth-silicon dioxide aerogel and the mixed use of the benzophenone ultraviolet light absorber and organic calcium (namely the calcium-zinc composite heat stabilizer). The heat resistance and the ageing resistance of the cable insulation protection layer are improved, so that the service life of the cable can be remarkably prolonged.
Optionally, the mass ratio of the salicylic acid rare earth-silicon dioxide aerogel to the N-substituted phenyl itaconimide derivative is 1: (0.5-0.7).

As can be seen from Table 2, the color differences for comparative examples 5-6 are significantly higher than for example 2, the 5% weight loss temperature is significantly lower than for example 2, and the tensile strength and volume resistivity are lower than for example 2, but the difference is smaller.
Compared with the rare earth salicylate-silicon dioxide aerogel or the N-substituted phenyl clothing-constantan imide derivative which are only used singly, the rare earth salicylate-silicon dioxide aerogel and the N-substituted phenyl clothing-constantan imide derivative are compounded to have better effect of improving the ageing resistance of the cable insulation protective material.

As can be seen from the combination of example 2, example 6 and table 2, the color difference, the 5% thermal weight loss temperature, the tensile strength and the volume resistivity of example 6 are all equivalent to those of example 2, and from the above, the anti-aging nano material adopts nano calcium carbonate and nano titanium dioxide, so that the anti-aging performance, the mechanical performance and the volume resistivity of the cable insulation protective material are equivalent.
