Abstract

The invention discloses an IoT field bus cable and preparation method thereof. The IoT field bus cable includes a bus cable inner core composed of a power transmission cable, an optical cable and a data cable; and a ceramic fiber fire resisting band, a fifth silicon rubber composite material anti-flaming layer, a nanometer inflaming retarding insulation layer and an inflaming retarding outer sheath wrapping the bus cable inner core in sequence. A third inflaming retarding filler is filled between the bus cable inner core and the ceramic fiber fire resisting band. In fire resistance tests, thecable provided by the invention meets a national standard GB / T 19216, and also meets requirements for C level, W level and Z level specified in a UK BS6387 standard. During the test process, short circuit and open circuit of the cable are avoided.

Description

technical field [0001] The invention relates to the field of the Internet of Things, in particular to an Internet of Things field bus cable and a preparation method thereof. Background technique [0002] With the rapid development of the national economy, the use of cables and the density of laying are getting higher and higher; especially in the field of the Internet of Things, the field bus of the Internet of Things involves the transmission of frequency division multiple data signals, voice signals, image signals and power signals. The existing technology uses optical fiber, data line, and power line to transmit the above-mentioned signals and data, resulting in spider web-like cables covering the entire site, which not only affects the stability and reliability of signal transmission, but also hinders the layout of other equipment on the site and install. [0003] In recent years, fires caused by electricity have increased year by year, and fires caused by wires and cab...
