Description

A kind of electric automobile charging pile cable halogen-free type thermoplastic elastomer cable material and its Preparation method
Technical field
The present invention relates to a kind of CABLE MATERIALS, more particularly to a kind of thermoplastic elastomer cable material and preparation method thereof.
Background technology
Hydrogenated polystyrene-(ethylene butene random copolymer)-polystyrene triblock copolymer (SEBS) is a kind of property The excellent thermoplastic elastomer (TPE) of energy has the property such as excellent weather-proof, anti-aging, heat-resisting, pressure-resistant compression deformation, recyclable recycling Can, thus it is widely used in appliance cord, the fields such as automobile making, building.But inflammability restricts the extensive use of SEBS, It therefore, can in the case of the less dosage of fire retardant using the mechanism of expandable flame retardant after the burning of New-type halide-free expansion type flame retardant Reach excellent flame retardant property, while the mechanical performance and softness for keeping SEBS itself excellent.
Traditional PVC and brominated class flame-retardant electric wire and cable and electronic connector because occur carcinogenic substance dioxin and A large amount of toxic dense smokes and corrosive gas are generated in combustion, this rescues the asphyxia for accelerating scene of fire personnel and increasing Help the rescue difficulty of personnel；And the corrosive gas of release will make scene of fire and neighbouring electric appliance be corroded and reported It is useless；In addition, halogenated flame retardant production, transport, storage, application, reject product removal process in there are toxicity accumulation and Generate carcinogen.Everything causes market there is an urgent need to a kind of environmental protection, low-smoke, the non-corrosive gas of Halogen, can reach The new material of UL-94V-0 fire-retardant ranks.
The energy and environmental issue have become world today's development distinct issues the most and influence China's sustainable development Open up one of most important factor of strategy.In recent years, with the ring increasingly reduced and vehicle exhaust is brought of international energy resource Border pollution problem displays, and the development of orthodox car receives obstruction, be instead then new-energy automobile development by More and more attention are arrived.At present, new-energy automobile is paid high attention to by various countries, and the Chinese government gives helping energetically It holds.The development environment of analysis and research China's new-energy automobile there is highly important reality to anticipate the development of new-energy automobile Justice.
Meanwhile global environmental consciousness increases in recent years, the limitation that wires and cables industry uses halogen containing material is increasingly Strictly, European Union formulated in 2002《About being forbidden to use certain Hazardous Substances Directives in electronic and electrical equipment》(ROHS).
