Problems solved by technology

However, to obtain the desired performance, 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
[0003] Chinese invention patent CN103232631A discloses a halogen-free low-smoke flame-retardant cable sheath material and its preparation method, but the flame retardants used in it are mostly hydroxide flame retardants, which will lead to a serious decline in mechanical properties
Chinese patent CN101012326A discloses a halogen-free flame-retardant cable sheathing material. Montmorillonite is added to the flame retardant to reduce the filling amount of hydroxide and improve processing performance, but the modification of montmorillonite mostly uses intercalation compounding method, the process is complicated and the production cost is high, and it is difficult to realize industrialized mass production

The flame-retardant cable material is prepared from the following raw materials in parts by weight: 90-110 parts of polyvinyl chloride, 1-5 parts of a melamine phytic acid flame retardant,30-50 parts of a plasticizer, 1-3 parts of a lubricant, 28-48 parts of a stabilizing agent and 4-6 parts of an antioxidant. The cable material containing the supramolecular self-assembly flame retardant has excellent thermal stability and flame retardance, and meets the performance requirements of cables.

Description

technical field [0001] The invention relates to the field of wire and cable material manufacturing, in particular to a cable material containing a supramolecular self-assembled flame retardant and a preparation method thereof. Background technique [0002] As one of the most widely used plastics in the modern world, polyvinyl chloride plays an important role in many consumer fields, such as automobiles, electronic materials and power cables. However, as a polymer material, polyvinyl chloride is prone to thermal decomposition and aging under the action of light, heat, oxygen, etc., which will eventually cause fire accidents due to aging of cables. Therefore, it is very necessary to improve its flame retardancy. Halogenated flame retardants are no longer accepted because they produce large amounts of toxic fumes during combustion. Compared with halogenated flame retardants, halogen-free flame retardants have become a hot spot in related fields due to their outstanding advant...
