Description

A kind of cable insulation rubber compounding
Technical field
The present invention relates to field of cables, more particularly to a kind of cable insulation rubber compounding.
Background technology
The evolution of electric wire product is substantially the update process of material.Electric wire is widely used, no It is widely different to its performance requirement with use occasion.The insulating materials of most of cable, except must have higher insulaion resistance, resistance to Outside voltage strength or low dielectric loss, it is necessary to take into account good physical and mechanical properties, such as tension, counter-bending, anti-vibration, anti- Turn round etc..
With the development of national economy, the raising of people's living standard, the commodity of in the market circulation are also increasingly particular about work( Can property, security, life-span etc., cable product, which has been at, to be continuously updated, in ripe, innovation cyclic process, New insulated Material emerges in an endless stream.Traditional rubber cable Insulation Material has seriously in terms of resistance to ag(e)ing, corrosion resistance, water-fast steam performance Defect, can not meet client's demand growing day by day.EP rubbers cable insulating material is by chemically stable full because of its main chain Constituted with hydrocarbon, therefore its resistance to ozone, heat-resisting, ageing-resistant performance are excellent, with good chemicals-resistant, electrical insulation capability, impact bullet Property, cryogenic property, low-density and high fillibility and hot water resistance and water-fast vapor permeability etc., suitable for wide in rubber cable Insulation Material It is general to promote the use of.
Ethylene propylene diene rubber has an ageing-resistant performance such as excellent resistance to ozone, heat-resisting, weather-proof, but ageing-resistant performance and tough Property should not enough, be used as restrictive coating, influence cable life-span.
The content of the invention
The object of the invention is exactly that there is provided a kind of cable insulation rubber compounding in order to make up the defect of prior art.
The present invention is achieved by the following technical solutions：
A kind of cable insulation rubber compounding, step is：
（1）Conductor is subjected to bundle strand, insulation is squeezed, spark-testing, stranding is wrapped, extrudes inner liner, armouring；
（2）Deionized water, emulsifying agent are well mixed, nano titanium oxide is added, stirred, 40-50 points of ultrasonic disperse Clock, adds butyl acrylate, stirs, and adds initiator, stirring reaction 30-40 minutes at 70-75 DEG C, obtains breast Liquid, is cleaned after being demulsified with ethanol, and spray drying obtains powder；
（3）Disperse the powder into ethyl acetate, methyl methacrylate be added dropwise, continue to stir 30-40 minutes after completion of dropwise addition, Initiator is added, stirring reaction 1-1.3 hours at 70-75 DEG C, emulsion is made, is cleaned and dried, obtains after being demulsified with ethanol Mixed material；
（4）Ethylene propylene diene rubber and mixed material, lead sulfate tribasic, barium stearate, zinc stearate are pressed into 70-73：12-15： 3-3.5：0.8-1：0.5-0.7 mass ratio mediates 5-8min in mill, is cooled to room temperature；
（5）1.5-1.6% sublimed sulfur is added in mill, 3-4min is kneaded, is extruded in outside armor and forms restrictive coating, room Temperature places 24-26h, vulcanizes on vulcanizer, produces high tenacity EPT rubber cable.
Step（2）Middle deionized water, emulsifying agent, nano titanium oxide, butyl acrylate, the mass ratio of initiator are 100- 120:1-1.2：8-9：23-25：0.1-0.2.
Step（3）Middle powder：In ethyl acetate：Methyl methacrylate：The mass ratio of initiator is 31-35:100- 110：25-26:0.1-0.2.
The solution that initiator is made into 3-4wt% is added.
Step（4）Middle mill temperature is 160-165 DEG C, and speed is 20-30r/min.
Step（5）The temperature of middle mill is 60-65 DEG C, and speed is 20-25r/min.
Step（5）The temperature of middle temperature vulcanizer is 160-163 DEG C, and pressure is 10-11MPa, and the time is 12-13min.
It is an advantage of the invention that：The restrictive coating of cable of the present invention coats nano titanium oxide using butyl acrylate, then uses Methyl methacrylate is wrapped up, and Soft Roll coating and hard outer layer are formd on nano titanium oxide surface, is being received impact or is being stretched When, there can be the performance of buffering, improve the toughness and tear resistance of protective cover material, while improving the ageing resistance of cable.
