Technical field

It blocks water flame-retarding metal silk braid over braid the present invention relates to braid over braid technical field more particularly to a kind of high-performance semiconductive And its manufacture craft.

Background technique

Now it is exclusively used in semiconductive band, the semiconductive gold of 110KV, 220KV and the above super-pressure underground cable conductive surface Belong to waterstop etc., though water preventing ability, semiconductive etc. are functional, there are still semiconductions can be unstable, and sheet resistance is uneven, Water-absorbing resin powder can fall off, and be to do vertical structure warp thread use though what is had is woven using tinned copper wire, no transverse structure Copper wire composition, there are no superior flame retardant properties, it is difficult to meet the super-pressure cable core semi-conductive screen belting layer such as 750KV, 1000KV Technical requirements.

Authorization Notice No. is that the patent of 101908390 B of CN discloses: waterproofing type semiconductive metal shields flame retardant woven Band, including base fabric and the conduction liquid, fire resistant fluid and the glue that blocks water that are attached in base fabric, base fabric is formed by warp thread, weft yarns, is passed through Yarn.It carries out in following processing steps: 1) sorting: warp thread, weft yarn；2) it weaves, warp thread and weft yarn is sent on high-speed knitter and compiled It knits；3) it applies conduction liquid: base fabric being sent into immersion liquid slot and applies conduction liquid；4) it dries: rolling and leveling after base fabric is dried；5) it applies fire-retardant Liquid: the base fabric Jing Guo above-mentioned processing is put into immersion liquid slot and applies fire resistant fluid；6) it dries: by rolling and leveling after the drying of above-mentioned base fabric； 7) it packs: braid over braid being vacuum-packed to form finished product；The patent does not solve above-mentioned semiconduction can unstable, sheet resistance Unevenly, the technical issues of water-absorbing resin powder can fall off.

Summary of the invention

It blocks water flame-retarding metal silk braid over braid and its manufacture craft the object of the present invention is to provide a kind of high-performance semiconductive, solution The technical issues of semiconduction in the prior art of having determined can be unstable, and sheet resistance is uneven, and water-absorbing resin powder can fall off.

A kind of high-performance semiconductive blocks water flame-retarding metal silk braid over braid, including water blocking layer, metal net layer and base, the resistance Water layer, metal net layer and base set gradually from top to bottom, between the base and metal net layer, metal net layer and water blocking layer it Between be provided with adhesive layer.

Based on the above technical solution, the present invention can also be improved as follows:
