Problems solved by technology

In addition, in the prior art, during the processing of PVC flame-retardant wires and cables, small-molecule plasticizers are added to greatly reduce the oxygen barrier index and reduce the flame-retardant performance of PVC wires and cables.
In order to meet the flame retardant requirements, it is necessary to increase the amount of high-priced flame retardants added in the formula, resulting in high production costs

Embodiment approach 1

[0032] 1. Mixture:

[0033] The various raw material formulations that make up the flame-retardant and anti-static PVC wire and cable material are weighed according to the following mass fractions respectively, and set aside.

[0034]

[0035] Put the PVC resin powder into the high-speed mixer, stir at high speed for 7 minutes to dry the water; then add synthetic vegetable fatty acid ester, stir at high speed for 5-10 minutes; then add the rest of the raw materials, stir at low speed for 3 minutes; In the mixer, stir for another 10 minutes, discharge the material after cooling, and prepare the flame-retardant and anti-static PVC wire and cable compound.

Abstract

The invention discloses a flame-retardant antistatic PVC wire and cable material and a preparation method thereof. Synthetic vegetable fatty acid ester with flame-retardant and antistatic properties and stone, ceramic tile and artificial stone polishing slag with flame-retardant and smoke-suppressing properties are added into the formula of the flame-retardant antistatic PVC wire and cable material, and the flame-retardant antistatic PVC wire and cable material is prepared by mixing, extruding and pelletizing. The synthetic vegetable fatty acid ester and the polishing slag are matched for useto generate a good synergistic flame retardant effect to replace an expensive flame retardant in the prior art, so that the production cost can be reduced, and the problem that the flame retardant property is reduced due to the addition of a large amount of small molecular plasticizers in the prior art is solved. A large amount of polishing slag is added as an inorganic filler, so that the production cost is reduced, the flame retardant property and smoke suppression performance of the flame-retardant antistatic PVC wire and cable material are improved, and the problems that stone, ceramic tiles and artificial stone polishing slag is difficult to recycle, and environmental pollution is caused by waste landfill are solved.

Description

technical field [0001] The invention relates to the technical field of flame-retardant cables, and mainly relates to a flame-retardant and antistatic PVC cable material and a preparation method thereof. Background technique [0002] Polyvinyl chloride PVC has excellent corrosion resistance, electrical insulation, and high chlorine content, it will degrade and release HCI and CO when burned. 2 , CO, toluene and other gases are isolated from oxygen and have self-extinguishing properties. They are ideal materials for the production of flame-retardant wires and cables. But HCI, CO 2 , CO, toluene, etc. are corrosive, poisonous and harmful gases that pollute the environment and cause "secondary harm" to the human body or equipment. People's lives and properties have brought huge losses. More and more practices have proved that it is not enough to only require flame retardancy, but also must have very low smoke generation to reduce the hazards of toxic fumes. In addition, in t...
