The silane cross-linked flame-retardant polyvinyl chloride cable material comprises the following components in parts by weight: 100 parts of PVC resin; 30-40 parts of a plasticizer a; 20-30 parts of plasticizer b; 5-10 parts of a flame retardant a; 5-20 parts of flame retardant b, 10-40 parts of filler a and 20-30 parts of filler b; 2-10 parts of a heat stabilizer; 0.5-2 parts of a lubricant; 0.1-0.3 part of antioxidant; 0.1-2 parts of silane cross-linking agent, wherein the silane cross-linking agent is a mixture consisting of silane a, silane b and silane c; 5-10 parts of a toughening agent a; 5-10 parts of a toughening agent b; 0.3-0.8 part of assistant. The silane crosslinking flame-retardant polyvinyl chloride cable material is mainly applied to places with high temperature resistance and high strength requirements, has higher gel rate, better mechanical strength and color stability, has high strength, heat resistance and creep resistance, and does not need lead salt as a catalyst. |
