Abstract

The invention belongs to the technical field of optical fiber sheath materials, and particularly relates to a special material for a 5G optical fiber sheath and a preparation method of the special material. The special material is prepared from PBT resin slices, an alpha-methylstyrene-acrylonitrile copolymer, aluminum silicate fibers, a titanate coupling agent, polyether, a light stabilizer, an ultraviolet light absorber and an antioxidant. According to the special material of the invention, the alpha-methylstyrene-acrylonitrile copolymer and the polyether are introduced into the PBT resin slices at the same time, so that the alpha-methyl styrene-acrylonitrile copolymer still can significantly increase the softening point of the PBT resin when being used at a low dosage, the heat resistance of the PBT resin is improved, and the problem of cost increase caused by a condition that that the heat resistance of the PBT resin is improved by adopting high-content alpha-methyl styrene-acrylonitrile copolymer in the prior art is solved; the polyether is doped into the PBT resin slices, so that the melt rheological property of the PBT resin slices in a melting processing process is improved,and the good processability of the PBT resin slices is ensured.

Description

technical field [0001] The invention belongs to the technical field of optical fiber sheath materials, and in particular relates to a special material for 5G optical fiber sheaths and a preparation method thereof. Background technique [0002] 5G, the fifth-generation mobile communication technology, is the latest generation of cellular mobile communication technology, and its performance targets are high data rate, reduced delay, energy saving, cost reduction, improved system capacity and large-scale device connection. The main advantage of the 5G network is that the data transmission rate is much higher than the previous cellular network, up to 10Gbit / s, which is faster than the current wired Internet and 100 times faster than the previous 4G LTE cellular network; Low network latency (faster response time), less than 1 millisecond, compared to 30-70 milliseconds for 4G. [0003] Optical fiber infrastructure has always been the basis for the development of mobile communica...
