Problems solved by technology

At the same time, there are reasons such as poor manufacturing quality, damage to the grounding system, overload, short circuit, overvoltage, and excessive contact resistance of the power cable line, which cause the cable line to catch fire and cause a fire, especially in the densely laid area in the channel, which leads to the expansion of the accident.
[0003] The current flame retardant cable sheath cannot effectively extinguish the flame generated by the cable, especially when a f

Embodiment 1～3 and comparative example 1

[0060] The preparation method of embodiment 1~3 and comparative example 1~3

[0061] Step 1. The filler is dried before use to remove moisture. Put the binary ethylene propylene rubber and ethylene-vinyl acetate into the internal mixer and mix for 5 minutes, then add the filler step by step. First add the lubricant and softener into the internal mixer for thorough mixing, then add the reinforcing agent, expansion agent, halogen-free flame retardant, sintering shell additive and smoke suppressant mixture together, and perform full internal mixing. Control it below (90°C in Examples 1-2, 100°C in Example 3), after banburying for 15-20 minutes, add processing aids such as antioxidant, brightener, accelerator and vulcanizing agent, and mix for 5 minutes Discharge.

[0062] Step 2. The sizing material after banburying is parked at room temperature (24h for embodiment 1-2, 48h for embodiment 3), and thinly passed through the open mill for 3-4 times. Sheet thickness is 6.8mm;

Abstract

The invention discloses a novel porous elastic material with convex-concave structure and for a fireproof flame-retardant plate and a preparation method and application thereof, belonging to the fieldof new materials. The material comprises the following components: resin, a lubricant, a softener, a reinforcing agent, an expanding agent, a halogen-free flame retardant, a sintering shell-forming additive, a smoke suppressant and a processing aid. The preparation method of the elastic material can be realized by adopting conventional equipment, raw materials are easy to obtain, and the elasticmaterial is reasonable in price and high in cost performance.

Description

technical field [0001] The invention relates to a fire-proof and flame-retardant plate elastic material with a porous convex-concave strip structure used in the fields of coated cables, new energy vehicle batteries, and building fire-proof partitions, as well as its preparation method and application, and belongs to the field of new materials. Background technique [0002] With the continuous progress of social development, the growth rate of various facilities in our country is very fast. In order to improve the quality of urbanization construction, supply of public products and facilitate project maintenance, power cables, gas, communication cables, water supply and drainage, heat and other pipelines are usually centralized Laying in the same public tunnel, such as underground comprehensive pipe gallery, pipe well of high-rise buildings, etc. The insulating sheath of the cable is made of polymer materials such as polyethylene, ethylene-vinyl acetate, etc., which are extrem...
