Abstract

The invention discloses a cold-resisting (40 DEG C below zero) and high-flame retardant (OI is greater than or equal to 38) PVC (Polyvinyl Chloride) cable material and a preparation method thereof. The cold-resisting (40 DEG C below zero) and high-flame retardant (OI is greater than or equal to 38) PVC cable material is prepared from the following raw material components in parts by weight: 50 parts of polyvinyl chloride resin A, 50 parts of polyvinyl chloride resin B, 10 to 20 parts of plasticizer A, 10 to 30 parts of plasticizer B, 10 to 30 parts of plasticizer C, 20 to 30 parts of plasticizer D, 5 to 10 parts of plasticizer E, 1 to 3 parts of forming agent, 5 to 10 parts of flame retardant A, 5 to 10 parts of flame retardant B, 5 to 10 parts of flame retardant C, 0.2 to 0.8 part of lubricant A, 0.2 to 0.8 part of lubricant B, 0.2 to 0.8 part of lubricant C, 1 to 2 parts of antioxidant A, 1 to 2 parts of antioxidant B, 4 to 8 parts of high-efficiency calcium zinc stabilizer and 40 to70 parts of mineral filler. The cable material disclosed by the invention has the characteristics of cold resistance (40 DEG C below zero), excellent high-flame retardant property (OI is greater thanor equal to 38) and the like, and is suitable for being used in harsh environments with higher flame retardancy and external extreme cold.

Description

technical field [0001] The invention relates to a cold-resistant (-40°C) high flame-retardant (OI≥38) PVC cable material and a preparation method thereof, belonging to the field of cable materials. Background technique [0002] With the outbreak of the "Okay Incident", the cable industry has raised its product quality requirements to a new height, and the cold resistance and flame retardancy of cable materials under extremely harsh conditions have been paid attention to. In the northeast and northwest of my country, the outdoor environment is harsh in winter, and the requirements for cold resistance are particularly high. However, the cold resistance and flame retardancy of PVC materials in the current cable industry seem to be a pair of contradictions. PVC materials with better cold resistance must have more plasticizers. If the percentage of plasticizers in the formula is large, the flame retardancy will decrease. Therefore, in the industry, PVC cable materials are genera...
