Abstract
The invention discloses a low-cost high-performance insulating rubber material which is prepared from the following raw materials in parts by weight: 60-80 parts of ethylene propylene diene monomer, 20-40 parts of elastomer, 2-5 parts of crosslinking agent, 1-2 parts of auxiliary crosslinking agent, 10-15 parts of plasticizer, 1-5 parts of anti-aging agent, 120-150 parts of talcum powder, 50-80 parts of argil and 4-6 parts of silica white. The low-cost high-performance insulating rubber material can be used for preparing various cable insulation core insulation layers, and is especially suitable for multi-core cables to prevent the cores from being flattening by the adjacent cores in the cable formation and jacket extrusion process.
Description
Technical field
The present invention relates to a kind of insulating material, relate in particular to a kind of hardness high, intensity is large, the low-cost and high-performance insulation rubber material of good insulation preformance.
Background technology
Insulating material is requisite part in wires and cables industry, and the quality of insulating property is to weigh the key factor of cable quality.In recent years along with the drop of price, ethylene-propylene rubber(EPR) becomes the only selection of insulating material already, and it also becomes the focus of studying in line cable industry.
The ethylene-propylene rubber(EPR) that prior art obtains, because needs ensure enough intensity, hardness is generally lower, therefore insulated wire cores is at stranding and extrude in oversheath process, insulation layer is subject to being very easily crushed and causing minor insulation thickness defective from the squeeze of adjacent core, in corresponding withstand voltage test, occur puncturing etc. off quality, cause above all operation futile efforts.
Ethylene-propylene rubber(EPR), compared with the plastics such as PE, PVC, is more prone to the phenomenon that insulated wire cores is crushed in stranding and squeeze jacket process, and this has had a strong impact on the quality of cable, even causes whole cable to be scrapped, and loses huge.
And by a large amount of fillings hardness of the next one-side raising ethylene-propylene rubber(EPR) of packing material cheaply, reduce costs, will certainly have influence on again the aspect such as intensity, the electrical property factor of insulation, even if product can be transferred client smoothly to, can not ensure that cable can have longer work-ing life.
Summary of the invention
Object of the present invention is exactly to overcome some shortcomings that exist in above-mentioned background technology, and a kind of high rigidity is provided, high strength, and high insulating property, what low cost and actual production processing performance were good can insulation rubber material.
For achieving the above object, disclosed a kind of low-cost and high-performance insulation rubber material, it makes the related raw material of effective constituent and counterweight ratio is:
60 ~ 80 parts of terpolymer EP rubbers;
20 ~ 40 parts, elastomerics;
2 ~ 5 parts of linking agents;
1 ~ 2 part of additional crosslinker;
10 ~ 15 parts, softening agent;
1 ~ 5 part, anti-aging agent;
120 ~ 150 parts of talcum powder;
50 ~ 80 parts, potter's clay;
4 ~ 6 parts of white carbon blacks.
As preferably, described linking agent is peroxidation diisopropyl benzene.
As preferably, described additional crosslinker is TAIC.
As preferably, described elastomerics is POE.
Compared with prior art, disclosed a kind of low-cost and high-performance insulation rubber material, tool has the following advantages:
High rigidity, the insulated wire cores that the insulating material in the present invention is made, insulation hardness is high, does not find that significantly phenomenon is flattened in insulation, has ensured the quality of cable in finished cable;
High strength, low cost, in the present invention, recipe ingredient is reasonable, in a large amount of filling, has obtained intensity at 9MPa, the High Performance Insulation material (standard-required intensity 5MPa, elongation 200%) of elongation 300% left and right;
High insulating property, the primary standard that insulating material need to reach is undoubtedly exactly insulating property, and this formula gained insulating material is in ensureing above-mentioned performance, and the volume specific resistance of material exceedes 4 × 10
15Ω cm, is applicable to 10kV and following midium voltage cable.
