Technical Field
The invention relates to the field of manufacturing of wire and cable materials, in particular to a cable material containing a supermolecule self-assembly flame retardant and a preparation method thereof.
Background
Polyvinyl chloride, one of the most widely used plastics in the modern world, plays an important role in many consumer fields, such as automobiles, electronic materials, power cables, and the like. However, polyvinyl chloride, which is a polymer material, is easily decomposed and aged by light, heat, oxygen, or the like, and the cable is finally aged to cause a fire accident. Therefore, it is very necessary to improve the flame retardancy. Halogenated flame retardants are no longer acceptable because they generate a large amount of toxic fumes during combustion. Compared with halogenated flame retardants, the halogen-free flame retardants are hot spots in related fields due to the outstanding advantages of no toxicity, drip resistance, environmental protection and the like. However, in order to obtain the desired properties, high doses of conventional halogen-free flame retardants are required. This inevitably leads to a reduction in the thermal stability and mechanical properties of the cable.
Chinese patent CN103232631A discloses a halogen-free low-smoke flame-retardant cable sheath material and a preparation method thereof, but most of the flame retardant used in the cable sheath material is hydroxide flame retardant, which causes serious reduction of mechanical properties. Chinese patent CN101012326A discloses a halogen-free flame-retardant cable sheath material, wherein montmorillonite is added into a flame retardant to reduce the filling amount of hydroxide and improve the processing performance, but the montmorillonite modification mostly adopts intercalation compound type, the process is complex, the production cost is high, and the industrial large-scale production is difficult to realize. Therefore, the search for more environmentally friendly and more efficient flame retardants is urgently needed in the field of cable manufacturing.
