Problems solved by technology

[0004] Some cables are used in harsh environments, which require cables to be soft, oil-resistant, wear-resistant, aging-resistant, resistant to environmental stress, wide temperature adaptability (-40 ° C ~ 65 ° C), better mechanical properties (higher tensile and tensile strength) Tear strength), which puts forward higher requirements for the sheath material of the cable, and the cable materials currently on the market cannot meet the above requirements at the same time
[0005] To sum up, the problems existing in the prior art are: (1) The cables of the prior art have poor oil resistance and abrasion resistance, narrow environmental adaptability, low tear strength and tensile strength, and cannot meet various performance requirements at the same time
[0006] (2) Aging resistance of cables
[0007] (3) Flame retardant problems of cables

preparation example Construction

[0033] Such as figure 1 Therefore, the preparation method of the high tear-resistant cable material provided by the embodiment of the present invention includes:

[0034] Chlorosulfonated polyethylene plastication, adding magnesium oxide, calcium hydroxide, white carbon black, nano-scale calcium carbonate, chlorinated paraffin and antimony trioxide, low molecular polyethylene wax, paraffin, plasticizer to the internal mixer in sequence Mixing materials such as agent DOTP / DOA. Special attention: Since the specific gravity of white carbon black and nano calcium carbonate is very small, they cannot be added at one time, but should be mixed in three times according to the proportion. The mixed film needs to be placed (to ensure performance, the storage time should not be less than 24 hours).

[0035] Before the cable production, add vulcanizing agent DCP, accelerator TAIC, and coupling agent silicon-69 to the placed film for the second mixing, and then it can be used for extrusi...

Abstract

The invention belongs to the technical field of cable materials, and discloses a high-tear-resistance cable material and a preparation method thereof. The high-tear-resistance cable material is prepared from chlorosulfonated polyethylene, magnesium oxide, white carbon black, nanoscale calcium carbonate, chlorinated paraffin, calcium hydroxide, an anti-aging agent RD, antimonous oxide, low-molecular polyethylene wax, paraffin, a coupling agent silicon -69, a vulcanizing agent DCP, an accelerant TAIC and a plasticizer DOTP/DOA. According to the invention, chlorosulfonated polyethylene is used asa base material, various polymers are sequentially added and mixed into a proper cable material according to a proper proportion obtained by countless tests, and the cable material has excellent mechanical properties, good oil resistance, good wear resistance and wide environmental adaptability and is a novel cable material with comprehensive excellent properties.

Description

technical field [0001] The invention belongs to the technical field of cable materials, and in particular relates to a high tear-resistant cable material and a preparation method. Background technique [0002] At present, the closest existing technology: cable is a wire product used to transmit electric energy, information and realize electromagnetic energy conversion. According to the characteristics of use, it can be divided into: power cables, cables for electrical equipment, bare wires, winding wires, communication cables and communication optical cables. [0003] Cables are mainly composed of conductors, insulation and sheath materials and shielding tapes, or armored tapes and filling materials. Among them, the role of insulation and sheath materials is very critical, not only to meet the insulation requirements of the product, but also to have good mechanical properties. [0004] Some cables are used in harsh environments, which require cables to be soft, oil-resista...
