Abstract

The invention discloses an antimony-less environment-friendly novel flame-retardant polyvinyl chloride cable material and a preparation method thereof. The antimony-less environment-friendly novel flame-retardant polyvinyl chloride cable material is prepared from the following materials in parts by weight: 100 to 150 parts of PVC (polyvinyl chloride) resin, 40 to 50 parts of polyester plasticizer, 4 to 8 parts of compound calcium-zinc stabilizer, 0.5 to 1 part of chemical lubricant, 25 to 40 parts of filler and 3 to 5 parts of components of a formula A. The formula A is prepared from the following materials in parts by weight: 0.6 to 1 part of zinc stannate, 1 to 2 parts of aluminium hydroxide, 0.8 to 1.2 parts of organic phosphorus flame retardant, 0.8 to 1.5 parts of nitrogen series flame retardant, 1 to 1.5 parts of ammonium polyphosphate, 1 to 2 parts of magnesium hydroxide, 0.1 to 0.3 parts of pentaerythritol and 0.1 to 0.3 parts of chemical lubricant. Besides flame-retardant property, the cable material disclosed by the invention also has excellent physical and chemical properties.

Description

technical field [0001] The invention relates to a flame-retardant polyvinyl chloride cable material and a preparation method thereof, in particular to an antimony-free and environmentally friendly novel flame-retardant polyvinyl chloride cable material and a preparation method thereof. Background technique [0002] As the outer coating material of wires and cables, cable materials need to have properties such as insulation and flame retardancy. In the prior art, antimonide and polyvinyl chloride are often added to the cable material to make the cable material have better flame retardancy. However, antimonides have strong pollution ability, and long-term use will cause strong pollution to the environment. Therefore, in the current technology, magnesium hydroxide and aluminum hydroxide are added to the cable material, and phosphoric acid-based flame-retardant materials, polyvinyl chloride and other additives are used for blending and extrusion, so that the cable material has ...
