Description

The preparation method of environment protection type high-strength fireproof cable line
Technical field
The invention belongs to field of cables, and in particular to a kind of preparation method of environment protection type high-strength fireproof cable line.
Background technique
Today's society electric power using all trades and professions all over the world, demand of the world to electric power is also increasing year by year, it is positive because So every year the fire because of caused by electricity be also to be continuously increased, especially in some public places, such as: megastore, hospital, The populated areas such as station.After just fitting up great fire occurs soon on December 15th, 2005, Liaoyuan, Jilin province downtown hospital Calamity accident causes 37 people dead, and 95 people are injured.Accident immediate cause is that switchgear house is not fire-retardant using cable, and short trouble occurs Afterwards, igniting flammable items.
Due to using common wire and cable once fire occurs, cable fire or other cables can be caused to run event Barrier, the equipment that will lead to each normal operation stops operating, while Dark smoke billows, on the one hand the decline of light transmittance moment will cause and set On the other hand standby damage loses indicative function because dense smoke and indicator light do not have power supply, causes trapped person that can not look for To escape opening, it will cause personnel and induce an illness because sucking volume of smoke, it is serious to be died because of asphyxia, while in no light Rescue personnel can not determine property and the specific location of trapped person under conditions of irradiation, and rescue is caused to lag, to cause big The property loss and casualties of amount.
Summary of the invention
The purpose of the present invention is to provide a kind of preparation methods of environment protection type high-strength fireproof cable line.
The present invention to achieve the above object, using following technical scheme:
A kind of preparation method of environment protection type high-strength fireproof cable line: the cable includes conductor, the conductor It is successively socketed with insulating layer, shielded layer, middle tegillum, waterproof layer, fire-proof high-temperature resistant layer and oversheath from inside to outside；Wherein, described Outer tube sleeve is prepared using following methods:
(1) melt blending: by polyolefin, plant ash, silane coupling agent, stearic acid, electrolytic zinc acid leaching slag according to above-mentioned ratio Example mixing stirs 10min with the speed of 600r/min, and then the melt blending 10min at 170 DEG C, obtains sizing material；
(2) it is crosslinked: after step (1) resulting sizing material is crosslinked 30min at 170 DEG C, being added and set according still further to the ratio Glue and white carbon black react 10min, obtain mixture；
(3) be granulated: step (2) resulting mixture is added in double screw extruder and carries out blending extrusion, then into Row is granulated, and obtains particulate material；
(4) prepare protecting pipe: particulate material obtained in step (3) is added in basic molding machine formed, sizing, After traction, cutting, outer tube is obtained；
The insulating layer includes following weight parts component: chlorinated polyethylene rubber accounts for 12-16 parts, organosilicon cross-linking agent accounts for 8-14 parts, trans- 1,2- dimethyl cyclohexane account for 12-16 parts, mica powder account for 4-8 parts, dimethyl silicone polymer account for 6-8 parts, rubber Softening oil accounts for 5-7 parts, dispersing agent accounts for 12-14 parts and polypropylene fibre accounts for 15-17 parts.
Compared with prior art, the beneficial effects of the present invention are:
The outer jacket tensile strength of the resulting cable of the application in 26MPa or more, elongation at break 750% or more, For oxygen index (OI) 36 or more, flame retardant property reaches A grades, has both the strong feature of significant intensity high flame resistance；Meanwhile it returning Plant ash and electrolytic zinc acid leaching slag is utilized in receipts, and reducing environmental pollution colleague reduces production cost, has significant economical Benefit and environmental benefit.
