Abstract
The antioxidant electrical cable material for cable sheath is prepared with low density polyethylene, linear low density polyethylene, high density polyethylene, linear high density polyethylene, antioxidant and polyethylene master batch, and through chemical synthesis and high temperature treatment. It is superior to polyethylene in antioxidant property, anticorrosion property, radiation resistance, mechanical performance and adhesion strength, and may be applied widely for various kinds of electric cables.
Description
Technical field
The present invention relates to be used for the oversheath material of machine-shaping cable.
Background technology
Usually cable is main by the core with conducting function, outside it, is provided with twining package tape, outside twining package tape, the oversheath material is formed oversheath through extrusion process.Because the application places of all kinds of cables is different, need stand the baptism of various outside atmospheres.Along with developing rapidly of economic construction, the improving constantly of people's standard of living, the fast development of all kinds of Infrastructure in town and country, increasing to all kinds of cable demands, to the heavy demand of all kinds of CABLE MATERIALS, more need be to the raising of cable quality.Wherein, the oversheath ground of cable directly contacts with outside atmosphere, and is impaired or encroached on like oversheath; Then cable just will lose its all functions; So, how to improve the oxidation-resistance of oversheath, the high thermal resistance and the preservative property of raising oversheath, be the common objective of interior industry.
Summary of the invention
The object of the invention is to invent a kind of antioxidant electrical cable material with blocking rheologic agent with tough, the no fusing point of antioxygen, high temperature resistant, preservative efficacy.
The present invention mainly is made up of new LDPE (film grade), linear low density polyethylene, high density polyethylene(HDPE), linear high-density polyethylene, oxidation inhibitor, Vilaterm masterbatch.
Each weight percent of said new LDPE (film grade), linear low density polyethylene, high density polyethylene(HDPE), linear high-density polyethylene, oxidation inhibitor, Vilaterm masterbatch is: 30～40%, 10～20%, 22～32%, 10～15%, 5～10%, 2～5%.
It is strong that the present invention has an antioxygen, anticorrosion, radioprotective, mechanical property than traditional Vilaterm, and degree of adhesion is that the conventional polyethylene CABLE MATERIALS is more than 2 times.The cable product that adopts the present invention to process has tough, the no fusing point of antioxygen, effect such as high temperature resistant, anticorrosion; Excellent mechanical property can all be arranged, dielectric properties, radiation resistance etc. in-200 ℃～1000 ℃ large-temperature range.This product is through chemosynthesis, and pyroprocessing improves performance, has more uniqueness, and product is widely used in electric wire, electronic cables, shielding cable, signal cable, space flight and aviation special cable etc.Be that polythene material becomes indispensable base mateiral in supporting.Can mix in all kinds of CABLE MATERIALS; Make the cable long service life; The break-make performance is good, has effects such as fire prevention, anticorrosion, waterproof, also has very strong bonding rate; Make all kinds of packing materials of restrictive coating and stranding contain knot rate height, not come off, solved the unsolved difficult problem of applying unit and manufacturer for many years.Mix a little antioxygen adhesion rheological agent of the present invention, can also reduce all kinds of CABLE MATERIALS starting material and cost 20%, especially can reduce the consumption of the energy, protect environment, it is light, firm that product uses, and improved the quality of CABLE MATERIALS widely.
The present invention has following characteristics:
1, mix a little CABLE MATERIALS of the present invention after; Have the cable long service life, anti-oxidant, performance good, stable mechanical performance; Hinder right performance and under 1000 ℃, do not burn, under 100 ℃ of very low temperature, do not ftracture, restrictive coating and stranding packing material contain the knot rate high, do not come off, characteristics such as antioxidant.
2, after the micro-CABLE MATERIALS of the present invention of adding, the antioxygen degree improves more than four times, and physical strength improves more than the twice, and the bonding rate has improved 100% with firm rate.
3, product performance
Guaranteed the stable of all kinds of cable performances; Main is to have improved quality product, has practiced thrift energy consumption, has practiced thrift social resources again; Practiced thrift production cost widely; Main is volume resistance power, is higher than national standard more than one times, and each item productive capacity all is better than the production standard of national regulation.
Second purpose of the present invention is the working method of a kind of said antioxidant electrical cable material with blocking rheologic agent of invention.
May further comprise the steps:
1) batch mixing: new LDPE (film grade), linear low density polyethylene, high density polyethylene(HDPE), linear high-density polyethylene, oxidation inhibitor and Vilaterm masterbatch are mixed;
2) hot melt: with above compound hot melt;
3) extrusion: the compound behind the hot melt is extruded through the mould that is provided with through hole, formed the bar shaped work in-process;
4) cooling: the bar shaped work in-process are crossed water for cooling;
5) drying: remove excessive moisture;
6) pelletizing:, form pellet with the segment of bar shaped work in-process.
In order to reach the humidity of variant prodn application requiring, can be dry again after pelletizing, or the water spray humidification.
In addition, with each weight percent batch mixing of 30～40% new LDPE (film grade)s, 10～20% linear low density polyethylenes, 22～32% high density polyethylene(HDPE)s, 10～15% linear high-density polyethylenes, 5～10% oxidation inhibitor, 2～5% Vilaterm masterbatch.
The present invention is easy to produce, and can practice thrift the production unit input, is beneficial to efficient production, and product performance are stable, reliable in quality.
Embodiment
1, batching
Take by weighing following each material respectively, even through mechanical thorough mixing, subsequent use:
New LDPE (film grade) 35kg
Linear low density polyethylene 15kg
High density polyethylene(HDPE) 27kg
Linear high-density polyethylene 13kg
Oxidation inhibitor 7kg
Vilaterm masterbatch 3kg
2, hot melt:, form the melting mixing raw material with above compound high temperature hot melt.
3, extrusion: the melting mixing raw material is extruded through the mould that is provided with through hole, formed the bar shaped work in-process.
4, cooling: the bar shaped work in-process are crossed water for cooling.
5, drying: remove excessive moisture.
6, pelletizing:, form pellet with the segment of bar shaped work in-process.
7, according to the humidity of variant prodn application requiring, can be dry again after pelletizing, or the water spray humidification.
