Problems solved by technology

However, wires and cables are prone to heating and burning due to short circuit during use, and are prone to aging changes, affecting use, etc. However, the polyvinyl chloride cable materials in the prior art are not good in terms of flame retardancy and aging resistance. It is very ideal, therefore, it will have very important practical significance to develop a flame-retardant and anti-aging PVC cable material with excellent performance.

Abstract

The invention discloses a flame retardant aging resistant polyvinyl chloride cable material and a preparation method thereof. The flame retardant aging resistant polyvinyl chloride cable material comprises the following components by mass: 60%-75% of polyvinyl chloride, 8%-15% of decabromo diphenylethane, 2%-4% of antimony trioxide, 1%-2% of a calcium zinc stabilizer, 10%-15% of a plasticizer, 1%-3% of a light stabilizer, 0.1%-0.5% of an antioxidant and 0.5%-1 % of a lubricant, the plasticizer is one or one than one of bis(2-propylheptyl) phthalate, dioctyl terephthalate, trioctyl trimellitate and dioctyl sebacate. The beneficial effect is that the flame retardant aging resistant polyvinyl chloride cable material has excellent flame retardant properties and mechanical properties, good processability, strong aging resistance, low cost and simple preparation process.

Description

technical field [0001] The invention relates to the technical field of power materials, in particular to a flame-retardant and aging-resistant polyvinyl chloride cable material and a preparation method thereof. Background technique [0002] Polyvinyl chloride cable material is based on polyvinyl chloride resin, adding stabilizers, fillers, lubricants and other appropriate amount of additives, and then mixing and kneading to extrude particles, mainly used to prepare wires, cables and other materials . However, wires and cables are prone to heating and burning due to short circuit during use, and are prone to aging changes, affecting use, etc. However, the polyvinyl chloride cable materials in the prior art are not good in terms of flame retardancy and aging resistance. It is very ideal, therefore, it will have very important practical significance to develop a flame-retardant and aging-resistant polyvinyl chloride cable material with excellent performance.
