Abstract

The invention discloses an environment-friendly polyvinyl chloride optical cable sheathing material and a preparation method thereof, and solves the technical problem of lack of an optical cable sheathing material which has high flame-retardant and rat-proof performance, has high performance in various indexes of a cable and is environment-friendly in the prior art. The optical cable sheathing material comprises the following components in parts by weight: 40-60 parts of PVC resin, 30-50 parts of calcium carbonate, 5-15 parts of POP, 3-10 parts of a plasticizer, 3-5 parts of an acrylate copolymer, 3-5 parts of a stabilizer, 5-10 parts of a flame retardant, 0.3-3 parts of a lubricant, 0.1-0.5 part of an antioxidant, 0.1-0.4 part of a pigment and 0.3-0.8 part of a rat-proof agent. The optical cable sheathing material prepared by the invention has excellent environmental stress cracking resistance, flame retardance, high and low temperature resistance, mechanical property and insulating property, low smoke amount and rat bite prevention; and the preparation method has the characteristics of simple production process, time saving and energy saving, and is suitable for industrial large-scale production.

Description

technical field [0001] The invention relates to an optical cable sheathing material and a preparation method thereof, in particular to an environment-friendly polyvinyl chloride optical cable sheathing material and a preparation method thereof. Background technique [0002] With the rapid development of my country's industrialization, business demands for communication systems, monitoring, and control have increased rapidly, and a large number of communication cables have been widely used. But at the same time, with the frequent occurrence of various accidents and disasters, optical cables, cables, etc. often play the role of the fuse, causing the fire to spread rapidly and damage valuable electronic instruments and equipment, affecting the normal operation of the entire line, and even causing A wider range of lines was paralyzed, thus expanding the damage of the disaster. The increasingly stringent fire safety standards and the rapid growth of communication line constructi...
