Problems solved by technology

[0002] With the prohibition of phthalic plasticizers in environmentally friendly wire and cable sheathing materials, cable material manufacturers urgently need to find alternative environmentally friendly plasticizers, and the comprehensive performance of environmentally friendly plasticizers currently on the market is often inferior to phthalic plasticizers. If you choose some kind of environmentally friendly plasticizer to simply replace the DOP in the original formula, it will be difficult to meet the national standard GB8815-2008 for wire and cable sheathing materials
And often there will be oil, frost and performance indicators that do not meet the requirements of the national standard GB8815-2008

Abstract

The invention discloses a plasticizer and a polyvinyl chloride (PVC) environmental-friendly electric wire and cable sheath material containing the plasticizer. The plasticizer for the PVC environmental-friendly electric wire and cable sheath material consists of 60 to 75 weight parts of epoxidized soybean oil, 20 to 35 weight parts of epoxy fatty acid methyl ester and 5 weight parts of compatilizers. The PVC environmental-friendly electric wire and cable sheath material consists of 50 weight parts of PVC, 20 to 30 weight parts of the plasticizer for the PVC environmental-friendly electric wire and cable sheath material, 20 to 30 weight parts of calcium carbonate, 0.2 to 0.5 weight part of barium stearate, 0.1 to 0.3 weight part of lead stearate and 0.3 to 0.6 weight part of stearic acid. The sheath material produced according to the invention can completely conform to the requirement of the national standard GB8815-2008, the use is convenient, and the cost is reduced. The requirements are met through the SGS standard tests.
