Abstract
The invention relates to the technical field of chemical engineering, in particular to a B1-grade flame-retardant 105-DEG C irradiation crosslinking halogen-free low-smoke insulated cable material, which 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 to 15 parts of a compatilizer; 100 to 160 parts of a flame retardant A; 40 to 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; and 1-2 parts of an accelerant. The preparation method of the cable material comprises the following steps: firstly, preparing the components in parts by weight; then adding the components into a high-speed mixer, stirring for 8-12 minutes at a high speed, and controllingthe temperature to be 50+ / -2 DEG C; and then adding the stirred materials into an internal mixer for internal mixing, discharging the materials when the temperature of the internal mixed materials reaches 150-155 DEG C, and performing double-cone forced feeding and granulation by a 75 / 180 double-stage extruder to obtain the B1-grade flame-retardant 105-DEG C irradiation crosslinking halogen-free low-smoke insulated cable material.
Description
technical field [0001] The invention relates to the field of chemical technology, in particular to a B 1 A grade flame-retardant 105°C radiation cross-linked halogen-free low-smoke insulating cable material, and a preparation method thereof. Background technique [0002] Wire and cable products play an important role in building and engineering safety systems, and most of the electrical fires in our country are caused by the aging and overloading of wires and cables. And the sheath material, resulting in further expansion of the fire accident. The toxic gas emitted by the insulation and sheath materials of wires and cables will cause a large number of casualties and hinder firefighters from extinguishing the fire. [0003] As people pay more and more attention to environmental protection and fire protection awareness, the fire department's requirements for the safety and reliability of fire protection systems for modern high-rise buildings, various important construction p...
