Description
Technical field
The present invention relates to cable processing technique field, and in particular to a kind of grease proofing cable and preparation method thereof.
Background technology
At present, the need for people are to fast transfer of data, information, to computer, word processor, fax sensor and logical
The dependence of news equipment significantly rapidly increases.The appearance of new technology make it that the equipment of this respect is online and networking,
It result in the comprehensive development of communication system.These systems are in the use increase of specific area, such as skyscraper, ship, aircraft, fire
Car, drilling platforms and mine.
For current America market, the index to electric wire has been not only simple insulation, fire-retardant, stretch-proof etc.
Aspect, but further have tightened up index to oil preventing performance, water resistance.But, although most of cable possesses
Grease proofing, fire-retardant, weatherability, but its product is anti-aging, and oil resistance is relatively low.
The content of the invention
The purpose of the present invention is to overcome the defect of above-mentioned prior art there is provided a kind of grease proofing cable, and the cable has preferable
Grease proofing effect, and anti-aging, fire resistance is preferably, is simple to manufacture, easy to operate, production cost is low.
Therefore, the invention provides a kind of grease proofing cable, including insulated wire cores group, internal shield, external shielding layer, interior shield
Set, high-temperature-resistant layer and oversheath, the insulated wire cores group have multigroup, and every group is formed by many insulated wire cores are stranded, often thoroughly does away with edge
Core includes conductor, internal shield, insulating barrier and external shielding layer successively from inside to outside, and the insulating barrier is twist wrapped in interior
Space is provided with screen layer and between two neighboring spiral, the insulating barrier outer surface is coated with fireproof coating layer, the insulation
Core group periphery is provided with band；The band outer surface is coated with inner sheath, high-temperature-resistant layer and oversheath successively from inside to outside；
A layer insulating is only wound between two-layer screen layer outside cable conductor by the way of spiral winding, it is to avoid
The thickness and weight of winding dielectric layers, have also reached preferable insulation effect.
The raw material components and weight content of the inner sheath are as follows：20-25 parts of butadiene-styrene rubber, phenolic resin 25-30
Part, 7-10 parts of cumyl peroxide, 40-45 parts of low density polyethylene (LDPE), 15-20 parts of nylon, 15-20 parts of magnesium hydroxide, have
5-8 parts of machine silicon, 20-30 parts of aluminium hydroxide, 8-20 parts of stearic acid, 10-13 parts of silicone oil, 2-4 parts of vinylacetate, stearmide
4-5 parts, 2-4 parts of antioxidant, 10-15 parts of vulcanizing agent and appropriate deionized water；Inner sheath causes cable has preferably grease proofing
Performance, and intensity is high, and service life is long.
The raw material components and weight content of the high-temperature-resistant layer are as follows：5-10 parts of mica particles, polyvinyl chloride resin powder
50-60 parts, polystyrene 30-35 parts of fat of acid, 10-15 parts of silicon rubber, 2-4 parts of antioxidant, 5-8 parts of paraffin oil, glass fibre 10-
15 parts, 5-8 parts of toughener；High-temperature-resistant layer causes cable to have preferable resistance to elevated temperatures, and flexible, is conducive to waterproof, resists
Aging.
The raw material components and weight content of the oversheath are as follows：40-50 parts of phenolic resin, anti-abrasion-resistant powder 3-5 parts, increasing
Mould 30-45 parts of agent, 2-4 parts of AVM, 4-10 parts of zinc oxide, 5-8 parts of magnesia, 5-10 parts of calcium stearate, hydrogenation fourth
20-25 parts of nitrile rubber, 2-4 parts of silicone powder, 2-3 parts of antioxidant MB, 15-20 parts of carbon fiber, 0.5-1.5 parts of antioxidant, high-strength iron
1-3 parts of based powders, 5-10 parts of cerous hypophosphate, 5-8 parts of molybdenum disulfide.
Molybdenum disulfide considerably increases the abrasion resistance of overcoat as anti-wear agent.Anti- abrasion-resistant powder is cooperateed with high temperature plasticization agent
Effect, enhances the hardness of cable and shows density, so as to play friction resistant effect.The termite-proof effect of AVM is preferable,
There is stronger toxic action to termite.
Zinc oxide, magnesia and calcium stearate are reinforcing agent, improve production efficiency, enhance the stretching of protection wearing layer
Intensity, improves hardness, while also improving anti-flammability so that the combination property of protection wearing layer is improved, and is enhanced whole
Body protection effect.
