Abstract

The invention relates to the field of sheath materials for communication cables and preparation methods for the sheath materials and particularly relates to an environment-friendly high-flame-retardance PVC (Polyvinyl Chloride) sheath material for the communication cables, a preparation method of the sheath material and use of the sheath material. The environment-friendly high-flame-retardance PVC sheath material for the communication cables, provided by the invention, is prepared from the following ingredients in parts by weight: 90-100 parts of PVC resin, 20-30 parts of polyester plasticizer, 10-20 parts of tricresyl phosphate, 10-20 parts of bis(2-propylheptyl) phthalate, 4-8 parts of thermal stabilizer, 15-30 parts of aluminum hydroxide, 3-10 parts of composite flame retardant, 6-20 parts of antimony trioxide, 8-15 parts of zinc borate, 0.5-1 part of glyceryl monostearate, 0.2-0.5 part of calcium stearate, 0.3-0.8 part of lignite wax, 0.1-0.4 part of bisphenol A, 0.1-0.4 part of antioxidant 1010, 0.1-0.2 part of antioxidant 168 and 5-15 parts of processing modifier. The environment-friendly high-flame-retardance PVC sheath material for the communication cables is in line with standards GB / T 8815-2008, RoHS and REACH; the sheath material has good extrusion processability, and surfaces of made products are smooth and delicate; and the sheath material has excellent flame retardance, can pass a test of bundled A-class combustion in IEC 60332-3 and is relatively low in production cost.

Description

technical field [0001] The invention relates to the field of communication cable sheath materials and preparation methods, in particular to an environment-friendly high flame-retardant PVC sheath material for communication cables and its preparation method and application. Background technique [0002] In recent years, with the rapid development of the communication field, more and more commercial office buildings and residential high-rise buildings adopt integrated wiring to meet people's needs for information transmission. In order to ensure the flame-retardant effect of the cables of the communication system, more and more communication cables are required to pass the bundled Class A combustion in IEC60332-3. In order to achieve a better flame-retardant effect for communication cables, high requirements are put forward for PVC sheathing materials for communication cables. According to the flame retardant mechanism of flame retardants, a variety of flame retardants are ge...
