Technical Field
The invention relates to the field of cable materials and preparation methods thereof, in particular to a wear-resistant polyvinyl chloride cable material and a preparation method thereof.
Background
The plastic used for the insulation and the sheath of the electric wire and the electric cable is commonly called as a cable material, and comprises various varieties such as rubber, plastic, nylon and the like. The polyvinyl chloride cable material (PVC cable material) is particles prepared by taking polyvinyl chloride as basic resin, adding a stabilizer, plasticizers such as dioctyl phthalate, diisodecyl phthalate, dioctyl terephthalate, trioctyl trimellitate and the like, inorganic fillers such as calcium carbonate and the like, additives such as an assistant, a lubricant and the like, and mixing, kneading and extruding.
With the market demand, the radio frequency line at the low temperature of-20 ℃ is limited in the use of products, and the cracking risk exists in the performance under the environment that the temperature is lower than-20 ℃ in winter in the north, so that the product sheath material with lower temperature and unchanged other performances is required. The rubber material at minus 40 ℃ can be added with cold-resistant plasticizer, namely DOA or DOS, so as to meet the requirements of 80 ℃ and vertical flame retardance, the addition amount of the low-temperature agent is too large, the rubber material can not pass through aging at 80 ℃, and the addition amount of the low-temperature agent is too small, and the rubber material can not pass through cold bending at minus 40 ℃. Therefore, it is necessary to develop a polyvinyl chloride cable material for radio frequency wires, which can simultaneously meet the flame retardant levels of-40 ℃ low temperature, 80 ℃ high temperature and VW-1, so as to be suitable for radio frequency wires with RG-174 specification and similar specification, meet market demand and promote further development of the technical field of cables. Therefore, it is necessary to invent a wear-resistant polyvinyl chloride cable material and a preparation method thereof to solve the above problems.
And the patent numbers are: the cable material prepared by the CN201910060738.X radio frequency wire polyvinyl chloride cable material and the preparation method thereof can simultaneously meet the radio frequency wire polyvinyl chloride cable material with the flame retardant levels of-40 ℃, 80 ℃ and VW-1, but the flame retardant level is still insufficient, the wear resistance of the cable material in the using process is poor, the cable material is not immediately put into cable manufacturing for use after production, and can pass through links such as storage, sale, transportation and the like, the time of the middle process is long, the cable material is usually stored in a granular form, the size is small, and the service life of the cable material is easily reduced due to the influence of the external environment.
Therefore, a wear-resistant polyvinyl chloride cable material and a preparation method thereof are provided to solve the above disadvantages.
