Abstract
The invention discloses a method for manufacturing a waterstop strap with a novel structure. The method is characterized by comprising the following steps of: mixing and stirring polyvinyl alcohol, modified terpene resin, superconducting carbon black, ultramicro low-silica-alumina ratio zeolite and fatty alcohol-polyoxyethylene ether which serve as raw materials and water to obtain a semiconductive shielding dye solution; putting terylene cloth into a pressurizing rubber tank with the semiconductive dye solution for soaking; taking the terylene cloth out, spraying water blocking powder with a certain thickness on the surface of the soaked terylene cloth uniformly, and drying at high temperature to obtain the waterstop strap with the novel structure; and rolling, slitting, and packaging. According to the method for manufacturing the waterstop strap with the novel structure, a semiconductive shielding dye in the manufactured waterstop strap is distributed in the terylene cloth uniformly, so that the waterstop strap is stable in performance, firm in combination with the terylene cloth and high in durability; and the waterstop strap can also neutralize space charges generated in the running process of cables to fulfill the aim of eliminating the space charges.
Description
Technical field
The present invention relates to power cable primary element field, particularly relate to a kind of preparation method of new structure waterstop.
Background technology
Along with the continuous expansion of power system, transmission distance increases gradually, the continuous increase of transmitted power, and direct current transportation more and more is used widely.Direct current transportation is the alternating current that the power plant is sent, be transformed into direct current through rectifier and be delivered to receiving end, with inverter direct current is transformed into a kind of power transmission mode that alternating current is delivered to the receiving end AC network again, have track investment few, do not have the system stability problem, regulate the advantages such as quick, reliable.But the space charge in the crosslinked polyethylene can be injected in the dielectric, causes the material internal electric field distortion, causes cable generation punch-through.
Generally can hold waterstop at cable outer layer, waterstop has the effect of radial water-resisting, simultaneously can and semiconductive shielding layer between play the effect of buffering and uniform electric field.But semiconductive shielding layer came off easily after traditional waterstop used a period of time, and perhaps skewness in waterstop makes unstable properties or the variation of waterstop.
Summary of the invention
The technical problem that the present invention mainly solves provides a kind of preparation method of new structure waterstop.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of preparation method of new structure waterstop is provided, comprises that step is:
(1) material polyethylene alcohol, modified terpene resin, superconductive carbon black, ultra micro low silica-alumina ratio zeolite, fatty alcohol-polyoxyethylene ether and water are carried out mix and blend, obtain the semi-conductive screen dye solution;
(2) woven dacron being put into the supercharging glue groove that fills the semiconductive dye solution floods;
(3) take out woven dacron, spray certain thickness water-proofing powder at impregnated woven dacron surface uniform, hyperthermia drying obtains the new structure waterstop, and carries out rolling, cuts, packs.
In a preferred embodiment of the present invention, the percentage by weight of raw material is described in the step (1): polyvinyl alcohol 11-13%, modified terpene resin 26-27%, superconductive carbon black 1%, ultra micro low silica-alumina ratio zeolite 3-5%, fatty alcohol-polyoxyethylene ether 2-5%, water 50-57%.
In a preferred embodiment of the present invention, mixing speed is 1000-1300 rev/min in the step (1).
In a preferred embodiment of the present invention, water-proofing powder thickness is 0.5-0.8mm described in the step (3).
The invention has the beneficial effects as follows: the preparation method of new structure waterstop of the present invention, the semi-conductive screen dyestuff is evenly distributed in woven dacron in the new structure waterstop that the method makes, guarantee described waterstop stable performance, be combined firmly with woven dacron, be not easy to come off, persistence is good, described waterstop can also in and the space charge of cable generation in service, prevent that space charge from shifting to insulator, can reach the purpose of eliminating space charge.
