The cable that the present invention produces has following characteristic after tested:
Table 2:
Annotate: all test datas of CABLE MATERIALS of the present invention all are to test through behind the warm water crosslinking in 1. upward showing;
2. going up in the table is to soak 7 days in 60 ℃ 15% NaCl solution behind the CABLE MATERIALS process warm water crosslinking of the present invention;
In polyvinyl chloride (PVC) RESINS, do not add the extremely strong mineral filler of water-absorbent (lime carbonate, potter's clay), to reduce the intrusion of moisture and chemical solution; Add the nonpolar polyester modification agent of aggretion type (EEA) of anti-extractable, to increase flexibility, winter hardiness and the erosion resistance of material; The softening agent that height of anti-resistance to hydrolysis the and lower temperature resistance are good (DOS) is to improve cold-resistant, the flexibility of material, the water-absorbent of reduction material and water-disintegrable; Add the high physics water-resisting agent polyethylene wax of oilness, to improve the waterproof solution and the processing characteristics of material; Add initiator, grafting agent, catalyst and other material and extrude and make material and mix infiltration and finish, the cable made of material can improve thermotolerance, oil resistant swelling and the cracking behavior and corrosion-resistant of material behind warm water crosslinking thus; Add environment-friendly type oxidation inhibitor and thermo-stabilizer to improve the antiaging agent and the thermostability of material, this CABLE MATERIALS is in the medium-term and long-term immersion of chemical solution, decreasing insulating can not appear, plastics hardening, cracking, swollen phenomenon, owing to added low temperature softening agent and soft properties-correcting agent, and adopted crosslinking process, can not occur ftractureing and hard crisp phenomenon, specifically seen Table 2 even this CABLE MATERIALS is used under-60 ℃ low temperature environment.
Compared with the prior art, beneficial effect of the present invention is embodied in:
1, polyvinyl chloride cable material of the present invention has the extremely low advantage of water-intake rate through behind the crosslinked with silicane in pharmaceutical chemicals, oil, soda acid salt brine solution, common flexible polyvinyl chloride cable material soaked 7 days in 60 ℃ 15% chemical solution, the pick up of common flexible PVC is 0.1～0.5%, the pick up of novel silane cross-linked polrvinyl chloride CABLE MATERIALS of the present invention under identical soaking conditions only is 0.0005～0.001%, so the pick up of this invention novel cable material is about one of percentage of common flexible polyvinyl chloride cable material.The reduction of pick up has greatly improved the erosion resistance of CABLE MATERIALS.
2, insulation electrical excellent property of the present invention after being embodied in this CABLE MATERIALS and soaking, the basic no change of CABLE MATERIALS volume specific resistance, does not have the phenomenon that descends in above-mentioned solution, remain at 3 * 10 before and after soaking
13～6 * 10
