Fog-surface flame-retardant polyvinyl chloride wire cable material and preparation method thereof

Abstract

The invention provides a fog-surface flame-retardant polyvinyl chloride wire cable material and a preparation method thereof. The wire cable material mainly comprises the following components in part by weight: 50 to 100 parts of polyvinyl chloride, 40 to 65 parts of calcium carbonate, 40 to 90 parts of plasticizer, 4 to 10 parts of fog-surface agent, 10 to 30 parts of compound aluminum hydroxide, 1 to 5 parts of antimony trioxide, 1.0 to 2.0 parts of nitrogen-phosphorus compound flame retardant, 3 to 7 parts of stabilizer and 0.5 to 150 parts of processing aid. The fog-surface flame-retardant polyvinyl chloride wire cable material is prepared through granulation by twin-screw extruders.

Description

Technical field [0001] The invention relates to a wire and cable material and a preparation method thereof, in particular to a matte flame-retardant polyvinyl chloride cable material suitable for power lines or connecting lines of household appliances, communication equipment and their spare parts, and a preparation method thereof. Background technique [0002] At present, the power cords or connecting lines used in household appliances and communication equipment, especially the connecting lines of communication equipment, often need to use matte, flame-retardant and flexible polyvinyl chloride wires and cables. Matte, soft, and flame retardant meet UL's VW-1 requirements; how to meet the requirements of the matte surface, currently in the market is mainly achieved by adding matte type polyvinyl chloride resin powder, the matte surface performance achieved by this method Save it when used, but the amount of material added is large, the cost is high, and the matte surface is roug...

Problems solved by technology

[0002] At present, the power cords or connecting wires for household appliances and communication equipment, especially the connecting wires of communication equipment often need to use matte, flame-retardant and soft PVC wires and cables. Matte, soft, and flame retardant to meet UL's VW-1 requirements; how to meet the requirements of the matte surface, the current market is mainly achieved by adding matte polyvinyl chloride resin powder, the matte surface performance achieved by this method It can be stored as soon as it is used, but the amount of material added is large, the cost is high, and this kind of matte surface is relatively rough and not very beautiful; another method is to add more calcium carbonate, especially heavy calcium carbonate, and then pass through when making wires and cables. Control the process temperature, especially reduce the temperature of the machine head, so that it does not produce gloss to achieve the effect of the matte surface. This method has the advantages of low cost and simple method, but after a period of time, the matte surface will disappear, and the retention time of the matte surface short

The wires and cables currently on the market often need to choose between soft wires with a matte effect and those that meet UL's VW-1 requirements. It often fails to meet the standard; the flame retardancy is good, but it cannot meet the softness requirements
