Abstract

The invention provides a low-smoke low-halogen flame-retardant PVC cable material and a preparation method thereof. The low-smoke low-halogen flame-retardant PVC cable material comprises the following components in parts by mass: 100 parts of PVC resin, 3-8 parts of nano LDHs complexing agent, 20-40 parts of aluminium hydroxide, 18-25 parts of dioctyl phthalate, 18-25 parts of dioctyl terephthalate, 2-4 parts of lead sulfate tribasic, 2-4 parts of dibasic lead phosphate, 0.5-1.5 parts of stearic acid, 0.5-1.5 parts of paraffin, 20-30 parts of calcium carbonate, 5-8 parts of antimony oxide and 5-8 parts of zinc borate. The PVC cable material provided by the invention is low-smoke, low-halogen and flame-retardant and has good flame retardance and good mechanical and electrical properties.

Description

technical field [0001] The invention relates to the field of cable materials, in particular to a low-smoke, low-halogen flame-retardant PVC cable material and a preparation method thereof. Background technique [0002] Polyvinyl chloride (PVC) is one of the five general-purpose plastics in the world, and its output is second only to polyethylene (PE), ranking second. Its superior cost performance, excellent processing performance and serviceability are widely used in new building materials and electrical processing. [0003] PVC has excellent processability, mechanical properties and electrical properties, and is widely used in the production of wire and cable. However, in the event of a fire, due to the concealment of the laying of the wires and cables, the easy spread of the fire caused by the laying of bundles makes it difficult to extinguish the fire of the cables and cables. Bring difficulties to firefighting, escape, lifesaving and other work. According to statistic...
