Embodiment 1

[0038] A kind of preparation method of fireproof type internet of things field bus cable, concrete steps are:

[0039] (1) Production of power transmission cable 1: several conductors are twisted into a first conductive core 11, and then a first silicone rubber composite flame-retardant layer 12 is extruded outside the first conductive core 11 to obtain a power transmission cable 1 ;spare;

[0040] (2) Make optical cable 2: take the first strengthening core 21 as the center, arrange six fiber cores 22 with cladding 23 and coating layer 24 around the first strengthening core 21 to make the first total cable; then use The double-layer co-extrusion process coats the first flame-retardant filling material 25 and the second silicone rubber composite material flame-retardant layer 26 on the outside of the first total cable to obtain the optical cable 2; standby;

[0041] (3) Make data cable 3: Extrude the third silicone rubber composite flame-retardant layer 33 outside the second c...

Abstract

The invention discloses a fireproof internet of things (IOT) field bus cable and a manufacturing method thereof. The fireproof IOT field bus cable comprises a bus cable core composed of a transmission cable, an optical cable and a data cable, as well as a ceramic fiber fireproof belt, a fifth silicon rubber composite flame-retardant layer, a nano flame-retardant insulating layer and a flame-retardant outer sheath wrapped outside the bus cable core in sequence; a third flame-retardant filling material is filled between the bus cable core and the ceramic fiber fireproof belt. The fireproof test of the cable not only can meet the requirement of national standard GB / T 19216, but also can meet the requirements of levels C, W and Z provided in British BS6387 standards; and in the test process, the cable is neither short-circuited nor open-circuited.

Description

technical field [0001] The invention relates to the field of the Internet of Things, in particular to a fireproof 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 wire...
