A fire retardant for cable pvc material

Abstract

The invention discloses a novel fire retardant for a PVC material of a cable. The fire retardant comprises aluminium titanate-cerium oxide and the consumption of the fire retardant is 1-10 wt% of the total weight of the PVC material, wherein aluminium titanate-cerium oxide can be used together with other conventional PVC material fire retardants and has relatively high flame retardancy, and the oxygen index can be above 35. The novel fire retardant has the characteristics of being low in addition and environmentally friendly.

Description

technical field [0001] The invention belongs to special PVC additives for cables, in particular to a flame retardant for cable PVC materials. Background technique [0002] Polyvinyl chloride (PVC) resin, as a thermoplastic with a long history, is widely used in the wire and cable industry. For example, many insulated wires, cables and cords of 450V / 750V and below used in daily life use PVC as the matrix resin. With the wide application of flame-retardant PVC cable materials in the fields of electronic appliances, computers, automobiles and aerospace, there are increasingly higher requirements for the flame retardancy of cables. [0003] Because PVC cables are mixed with a large amount of plasticizers and other additives, their flame resistance is insufficient, and HCl gas that is harmful to the human body will be produced when burned, and HCl will also have a strong corrosion effect on metals. In addition to producing toxic gases, a large amount of smoke will be produced d...
