Embodiment 2

[0022] Please refer to figure 2 , the manufacturing method of the outer sheath of the present embodiment comprises the following steps:

[0023] Step 201: calcining coal gangue particles at a temperature of 800-900° C. to obtain calcined powder;

[0024] In step 201, the coal gangue particles are calcined to maximize the evaporation of the moisture contained in them, and during the calcination process, suspension calcination can be used during the calcination process at 800-900°C (preferably 850°C) The purpose of calcination is to remove the crystallization water (hydroxyl SUI) in the lattice of coal gangue particles through high temperature, volatilize organic matter, make the pores in the structure open, and improve the adsorption force and activity. Specifically, the coal after calcination The water content of gangue powder is less than 2%.

[0025] Step 202: adding the calcined powder and the modifier to the powder modification equipment for modification to obtain modif...

Abstract

The invention relates to the field of cables, and particularly relates to an outer sheath of a fire-resistant cable, and a production method thereof. The outer sheath of the fire-resistant cable comprises the compositions in parts by weight: 43-47 parts of coal gangue particles, 7-9 parts of aluminum hydroxide, 5-7 parts of diantimony trioxide, 23-27 parts of ethylene propylene diene monomer (EPDM), 0.8-1.2 parts of modifier, 10-12 parts of vulcanizing agent, 3-5 parts of stabilizer, 0.4-0.8 part of stearic acid, 5-7 parts of paraffin oil, and 3-6 parts of dicumyl peroxide. According to the outer sheath of the fire-resistant cable, provided by the invention, the emission amount of hazardous and toxic gas in the burning process can be reduced, and the content of hazardous and toxic gas in a fire scene can be decreased so as to guarantee the life security of rescuers.

Description

technical field [0001] The invention relates to the field of cables, in particular to an outer sheath of a flame-retardant cable and a manufacturing method thereof. Background technique [0002] Flame retardant cable is a commonly used cable. Specifically, it refers to a power cable that can self-extinguish after the sheath of the cable is burned, only for a limited distance. Greater loss. [0003] However, in related technologies, when the sheath of the cable burns, a large amount of harmful gas such as carbon monoxide and hydrogen halide will be produced and permeate the fire scene; serious threat. Contents of the invention [0004] The object of the present invention is to provide an outer sheath of a flame-retardant cable to solve the above-mentioned problems. [0005] An outer sheath of a flame-retardant cable is provided in an embodiment of the present invention. According to parts by weight, 43-47 parts of coal gangue particles, 7-9 parts of aluminum hydroxide, ...
