Problems solved by technology

[0007] Landfill method: it occupies a large area, conflicts with urban construction for land, and landfill costs are high. Most of them are buried together with other urban solid waste. The organic matter seeping out of the landfill pollutes water sources and affects the underground ecological environment.
[0008] Incineration method: Incineration of redundant other urban waste solid wastes together, producing toxic gases and polluting the atmosphere. The non-toxic treatment equipment for incineration has a large investment and high cost (more than 2 billion yuan is required to build a large incineration plant)
[0009] Both landfill and incineration waste useful materials and energy in waste XLPE cable materials

Embodiment 1

[0026]

[0027] (1) Routinely pulverize the waste XLPE cable material to obtain a coarse powder with a particle size of 0.1~10mm; then use the solid phase force chemical reactor (patent No. 95111258.9 solid phase force chemical reaction device) for solid-phase ultrafine pulverization to obtain ultrafine powders with a particle size of 20 μm to 100 μm. (2) Ultrafine powder of waste XLPE cable material, styrene-butadiene-styrene block copolymer (SBS YH 792, Baling Petrochemical), 32# white oil, KH-550 (Nanjing Nengde Chemical Co., Ltd.), triphenylphosphine oxide (Clariant), and antioxidant 168 (provided by Ciba) were added into a mixer and stirred evenly, and then blended and granulated by a twin-screw extruder. The output process is: the screw speed is 400r / min; the temperature from the machine head to the feeding port is: 205°C in the first zone, 215°C in the second zone, 220°C in the third zone, 225°C in the fourth zone, 220°C in the fifth zone, 220°C in the sixth zone, an...

Abstract

The invention discloses a flame retardant TPE made from waste crosslinked polyethylene cable materials and a preparation method thereof. The TPE comprises, by weight, 200-400 parts of the waste crosslinked polyethylene cable materials, 300-500 parts of styrene-butadiene-styrene block copolymers, 10-100 parts of extending oil, 1-20 parts of silane coupling agents, 100-200 parts of phosphonate flame retardants and 0-10 parts of other auxiliaries. According to the TPE, a path is provided for recycle of the waste crosslinked polyethylene cable materials, the cost and environmental pollution can be reduced, and resources can be saved. The prepared TPE is provided with good flame retardance and other performances up to standards.

Description

technical field [0001] The invention relates to a flame-retardant thermoplastic elastomer produced by using waste cross-linked polyethylene cable material and a preparation method thereof. Background technique [0002] In recent years, with the acceleration of the construction of the national grid and the successive investment of UHV projects, the development of the wire and cable industry has been greatly promoted. According to statistics, in the past 15 years, the average annual growth rate of the wire and cable industry has reached more than 15%, becoming the second largest industry in my country's mechanical and electronic industry after the automobile industry, and its production capacity surpassed that of the United States, ranking first in the world. During the "Twelfth Five-Year Plan" period, the total investment in my country's power grid will reach 2.9 trillion yuan. It is foreseeable that large-scale power grid construction such as west-to-east power transmission,...
