Problems solved by technology

A large number of low-smoke and halogen-free cable materials will inevitably produce a lot of waste low-smoke and halogen-free cable sheaths during long-term use. At present, due to the research on the reuse of low-smoke and halogen-free cable sheaths, it is still in its infancy. Therefore, this The low-smoke and halogen-free cable sheaths are not used efficiently, but are discarded at will, which causes a lot of waste of resources and also brings a lot of solid waste to the environment.

Embodiment 1

[0023] A method for preparing a recycled low-smoke and halogen-free cable material, comprising the following steps:

[0024] (1) Take waste low-smoke and halogen-free cable sheaths, sort and remove impurities such as wire cores and non-low-smoke and halogen-free cable sheaths. Among them, the density of waste low-smoke halogen-free cable sheath is 1.48g / cm 3 ;

[0025] (2) Use a crusher to crush the sorted waste low-smoke and halogen-free cable sheaths. The maximum size of the crushed material is 10mm×10mm×10mm, and the smallest size is almost powdery. The smaller the size of the crushed material, the better. Considering the difficulty of operation and production cost, it is best not to be larger than 10mm×10mm×10mm.

[0026] (3) Centrifugally wash the scrap in step (2) with water to mainly remove impurities such as dust and silt in the scrap.

[0027] (4) Dry the scraps after cleaning. Drying can be natural drying, dryer drying or vacuum dryer drying, etc., to ensure that ...

Embodiment 2

[0033] A method for preparing a recycled low-smoke and halogen-free cable material, comprising the following steps:

[0034] (1) Take waste low-smoke and halogen-free cable sheaths, sort and remove impurities such as wire cores and non-low-smoke and halogen-free cable sheaths. Among them, the density of waste low-smoke halogen-free cable sheath is 1.45g / cm 3 ;

[0035] (2) Use a crusher to crush the sorted waste low-smoke and halogen-free cable sheaths. The maximum size of the crushed material is 10mm×10mm×10mm, and the smallest size is almost powdery. The smaller the size of the crushed material, the better. Considering the difficulty of operation and production cost, it is best not to be larger than 10mm×10mm×10mm.

[0036] (3) Centrifugally wash the scrap in step (2) with water to mainly remove impurities such as dust and silt in the scrap.

[0037] (4) Naturally dry the cleaned scrap to ensure that the moisture content in the scrap is not more than 0.3% (by weight).

Embodiment 3

[0043] A method for preparing a recycled low-smoke and halogen-free cable material, comprising the following steps:

[0044] (1) Take waste low-smoke and halogen-free cable sheaths, sort and remove impurities such as wire cores and non-low-smoke and halogen-free cable sheaths. Among them, the density of waste low-smoke halogen-free cable sheath is 1.46g / cm 3

[0045] (2) Use a crusher to crush the sorted waste low-smoke and halogen-free cable sheaths. The maximum size of the crushed material is 10mm×10mm×10mm, and the smallest size is almost powdery. The smaller the size of the crushed material, the better. Considering the difficulty of operation and production cost, it is best not to be larger than 10mm×10mm×10mm.

[0046] (3) Centrifugally wash the scrap in step (2) with water to mainly remove impurities such as dust and silt in the scrap.

[0047] (4) Carry out dryer drying to the crushed material after cleaning, ensure that the moisture content in the crushed material is ...

Abstract

The invention discloses a regenerative low-smoke halogen-free cable material and a preparation method thereof. The regenerative low-smoke halogen-free cable material comprises the following components in parts by weight: 100 parts of waste low-smoke halogen-free cable crushed material, 0.3-0.5 part of lubricant, 0.2-0.3 part of antioxidant and 0.5-0.8 part of color masterbatch. The preparation method comprises the steps of sorting for removing impurities, crushing, cleaning, drying, kneading, extruding, granulating and packing. The regenerative low-smoke halogen-free cable material of the invention has the following indexes: the tensile strength is greater than or equal to 10.0MPa, the elongation at break is greater than or equal to 150.0%, the low temperature brittleness impact temperature is -30 DEG C, the volume resistivity at 20 DEG C is greater than or equal to 1.0*10<10> omega.m, and the oxygen index is greater than or equal to 33.0%, wherein the indexes all exceed the national standards. The regeneration method of the invention can be used for preparing the regenerative low-smoke halogen-free cable material efficiently, increases the utilization ratio of resources, reduces the pollution of solids wastes, has large economic prospect and generates good social benefit simultaneously.

Description

technical field [0001] The invention relates to a low-smoke halogen-free cable material and a preparation method thereof, in particular to a recycled low-smoke halogen-free cable material and a preparation method thereof. Background technique [0002] At present, with the rapid development of the power industry, especially the arrival of the 3G era, the wire and cable industry has brought great opportunities for development, but at the same time there are many challenges. One of the many challenges addressed is the efficient production and efficient use of cable materials. Traditionally used cable materials are mostly PVC cable materials, which do not have environmental protection function because they contain chlorine elements, and are gradually replaced by low-smoke halogen-free cable materials. Low-smoke halogen-free cable materials are mainly composed of thermoplastic materials such as EVA and PE, and additives are added to them. A large number of low-smoke and halogen...
