Abstract
The present invention relates to cable processing technique field, specifically provide a kind of flame retardant cable, including insulated wire sandwich layer, screen layer, enhancement layer, high-temperature-resistant layer and overcoat, the insulated wire sandwich layer is formed by many insulated wire cores are stranded, every insulated wire cores are made up of conductor and the high-temperature insulating layer being coated on outside conductor, and the screen layer is wound in insulated wire sandwich layer periphery, and enhanced layer packets are rolled in screen layer periphery, high-temperature-resistant layer is located at enhancement layer outer surface, and overcoat is coated on enhancement layer outer surface；The high-temperature insulating layer is ethylene tetrafluoroethylene copolymer layer；The method for preparing above-mentioned flame retardant cable is additionally provided, is prepared simply, it is easy to operate.The flame retardant cable of preparation, not only with preferable fire retardant performance, and high temperature resistant, tension, bending resistance, pliability is good, wear-resisting, has good protective action to oxygen, high-energy radiation and poisonous metal aging.
Description
Technical field
The present invention relates to cable processing technique field, and in particular to a kind of flame retardant 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.
The insulating barrier and restrictive coating of existing flame retardant cable are usually to be mixed and made into single fire retardant and CABLE MATERIALS.By
Single in fire proofing, cable can not only produce a large amount of smog and toxic gas in use, but also can be anti-because of dehydration
Answer and reduce cable performance, so as to influence the resistance combustion temperature and duration of fire resistance of cable, it is difficult to reach fire prevention, moistureproof effect.
Due to having formulated more strict fire safety standard, cable insulation material needs to improve its burning and invention
Can, while keeping excellent physical property, need to improve its flame biography for low expense wire cable insulating material compositions
Broadcast and smoke generation characteristics, while to there is excellent physical property.
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 flame retardant cable and preparation method thereof, resistance
Combustion performance is good, and high temperature resistant is simple to manufacture, easy to operate.
Therefore, the invention provides a kind of flame retardant cable, including insulated wire cores group, screen layer, enhancement layer, high-temperature-resistant layer and
Overcoat, insulated wire cores group has multigroup, and every group is formed by many insulated wire cores are stranded, and every insulated wire cores are by conductor and are coated on
High-temperature insulating layer outside conductor is constituted, and the screen layer is wound in insulated wire cores group periphery, and enhanced layer packets are rolled in screen layer appearance
Face, high-temperature-resistant layer is located at enhancement layer outer surface, and overcoat is coated on enhancement layer outer surface；The high-temperature insulating layer is ethene-four
Fluoride copolymers layer；
The flame retardant cable that the present invention is provided, not only with preferable fire retardant performance, and also high temperature resistant, Stability Analysis of Structures,
Tensile capacity is strong, not easy to break, there is good protective action to oxygen, high-energy radiation and poisonous metal aging, and toughness is high, prepares
Simply, it is easy to operate.
We use the raw material components and weight content of high-temperature-resistant layer as follows：5-10 parts of mica particles, polyvinyl chloride
50-60 parts of resin-oatmeal, 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
10-15 parts of fiber, 5-8 parts of toughener；
In addition, we use the raw material components and parts by weight content of overcoat as follows：40-50 parts of phenolic resin, hydrogen
20-30 parts of magnesia, 30-45 parts of high density polyethylene (HDPE), 2-4 parts of melamine cyanurate, 5-7 parts of aerosil, Ca/
5-7 parts of Zn compound stabilizers, 2-3 parts of magnesium stearate, 5-10 parts of cerous hypophosphate, 10-15 parts of halogen-free expansion fire retardant, three oxidations
Two 5-8 parts of antimony, 2-3 parts of Firebrake ZB, 10-15 parts of polytetrafluoroethylene (PTFE), 3-5 parts of anti-wear agent, 5-7 parts of plasticizer.
