Abstract
The invention relates to the technical field of chemical industry, in particular to a chemical material B1Grade flame-retardant 105 ℃ irradiation crosslinking halogen-free low smokeThe insulated cable material comprises the following components in parts by weight: 30-45 parts of a base material A; 40-60 parts of a base material B; 10-15 parts of a compatilizer; 100-160 parts of a flame retardant A; 40-60 parts of a flame retardant B; 1-2 parts of an antioxidant; 5-8 parts of a lubricant; 1-2 parts of a coupling agent; 1-2 parts of an accelerator. The preparation method of the cable material comprises the following steps: firstly, preparing each component according to the weight part ratio; then adding the components into a high-speed mixer, and stirring at high speed for 8-12min, wherein the temperature is controlled at 50 +/-2 ℃; then adding the stirred materials into an internal mixer for internal mixing, discharging the materials when the temperature of the internal mixing materials reaches 150-1The grade flame-retardant 105 ℃ irradiation crosslinking halogen-free low-smoke insulating cable material.
Description
Technical Field
The invention relates to the technical field of chemical industry, in particular to a B1Grade flame retardant 105 DEG CAn irradiation crosslinking halogen-free low-smoke insulating cable material and a preparation method thereof.
Background
The electric wire and cable products play an important role in building and engineering safety systems, most of electric fires in China are caused by aging and overload use of the electric wire and cable, and meanwhile, combustible insulating and sheathing materials in the electric wire and cable are ignited in the case of the fire, so that the fire accidents are further expanded. Toxic gases emitted from the combustion of the insulation and sheathing materials of the electric wires and cables cause a great deal of casualties and prevent fire fighting of fire fighters.
With the increasing attention paid to environmental protection and fire protection, the requirements of fire departments on the safety and reliability of modern high-rise buildings, various important construction projects and residential facility fire protection systems are continuously improved. A large amount of organic chemical materials are used in modern buildings, so that the traditional electric wires and cables are no longer suitable for the actual conditions of violent fire flames and extremely high temperature of the modern buildings, and the flame retardant grade and the fire resistance grade of the electric wires and cables are very necessary to be improved.
