Description
Technical field
The present invention relates to a kind of high-performance electric wire and its preparation technology, belong to CABLE MATERIALS technical field.
Background technology
After human knowledge and using electricity, an electricity part indispensable in just being lived into us.Wire conduct carrying,
The carrier of transport electricity is paved with regional, how as insulating protection to be always emphasis that we study preferably to wire.
Cable is typically the wire set for the similar rope that by several or several groups of wires (every group at least two) are twisted
Body, it is erected in the air or mounted in underground, the bottom, for telecommunication or power Transmission more.In face of complicated various wire, cable is in itself
For protecting the materials of insulating barrier just to have high requirement.
The selection of cable material is various with making species, and quality gap is larger, generally from resin, plastics, silicon rubber etc.
For main material, other processing aids, vulcanizing agent etc. is coordinated to be made.Change tool of the common cable material to use environment
Have compared with hypersensitivity, can not be well protected against.
The shortcomings that can not adapting to use environment very well for traditional cable material, publication number 105924729A discloses one kind
Improve the cable material of fire resistance and mechanical property.However, cable material can not be made by improving fire resistance and mechanical property
Use use environment complicated and changeable.

The processing of electric wire is the processing of plastic products, and present processing mode is more ripe, generally selects
Known plastic machine is processed.But wire cable material, as a kind of mixture, the selection of different materials and proportioning all can shadows
Ring operating personnel for and its parameter selection.It must suitably be chosen such as according to the physicochemical properties of different materials in dispensing
The conditions such as temperature, process time.Heterogeneity of the present invention according to material, using first portion of material melting mixing, is re-fed into close
Machine refining is carried out in surplus material in mill, during which adjusts mixing speed, machine refining time and temperature so that material is sent out to greatest extent
Wave its performance.Product apparent property is lifted finally by control extrusion temperature.
Preferably, in step (2), mixing speed is 600-700r/min, mixing time 10- in the melting
15min, melt mix temperature are 150-200 DEG C, time 10-20min.According to the build-in attribute of different materials in preparation technology
To choose temperature and process time to ensure that the property of various materials is stable.
Preferably, in step (3), the processing temperature of the machine refining is 100-200 DEG C, process time 10-
20min。
Preferably, in step (4), the extrusion temperature is 100-200 DEG C.Control extrusion temperature can effectively change production
The apparent property of product.
Compared with other materials, the invention has the advantages that：
(1) content of the plasticizer in material and polyvinyl chloride is close to 1-1.5:1, increasing substantially the dosage of plasticizer makes
Product has good flexility, meets the product cutting processing of different size.
Being used in mixed way for (2) two kinds of plasticizer, can preferably cooperate with the performance for playing different plasticizer.
(3) nano-meter characteristic of nm-class active calcium carbonate can effectively adjust the rigidity of polyvinyl chloride composite materials, toughness, bright and clean
Degree and bending strength, improve its processing characteristics and rheological property, influence the heat-resistant stability of polyvinyl chloride composite materials, have
Filling and the effect of enhancing toughness.
(4) melamine, tributyl phosphate be as traditional organic fire-retardant, itself possesses good fire resistance, and nothing
Machine fire retardant magnesium hydroxide is as additive flame retardant, and with its simple operation, the characteristics of flame retardant effect is strong further improves product
Fire-resistance property.
(5) extrusion temperature is controlled according to material character, the apparent property of product can be optimized.
