Embodiment Construction

[0012] Soft and environmentally friendly polyolefin cable compound, made of raw materials with the following weight (kg):

[0013] PE resin powder 25, EVA45, POE elastomer 14, ACR resin 4, magnesium hydroxide 25, aluminum hydroxide 25, talcum powder 15, molybdenum trioxide 5, iron oxide 2, tributyl citrate 8, antioxidant 1010 2. Acetyl triethyl citrate 26, pentaerythritol 1, melamine cyanurate 2, polytetrafluoroethylene 1, stearic acid 1, paraffin wax 2, modified filler 9.

[0014] The preparation method of cable material of the present invention:

[0015] Weigh the raw materials of each component according to the proportion of the formula, stir the weighed raw materials in a high-speed mixer, and then banbury in an internal mixer at a temperature range of 155-175°C, extrude with twin-screws, and grind the surface eagerly Granulating, feeding by cyclone separator, screening by vibrating screen and then packaging to get the finished cable material.

[0016] Wherein, the modif...

Abstract

The invention provides a soft environment-friendly polyolefin cable material prepared from the following raw materials in parts by weight: 20-30 parts of a PE resin powder, 40-50 parts of EVA, 10-15 parts of a POE elastomer, 4-5 parts of ACR resin, 20-30 parts of magnesium hydroxide, 20-30 parts of aluminum hydroxide, 10-20 parts of a talcum powder, 4-5 parts of molybdenum trioxide, 2-3 parts of iron oxide, 8-10 parts of tributyl citrate, 1-2 parts of an antioxidant 1010, 20-30 parts of triethyl O-acetylcitrate, 1-2 parts of pentaerythritol, 1-2 parts of melamine cyanurate, 1-2 parts of polytetrafluoroethylene, 1-2 parts of stearic acid, 1-2 parts of paraffin, and 8-10 parts of a modified filler. The cable material has high softness degree and excellent mechanical properties, and can meet use in communication cables, weak electric cables and other industries having higher demands on the cable softness degree.

Description

technical field [0001] The invention relates to the field of cable materials, in particular to a soft and environment-friendly polyolefin cable material. Background technique [0002] With the rapid development of the global economy and the enhancement of human awareness of environmental protection, the requirements for the quality and performance of wires and cables in various fields are getting higher and higher, and there are more and more fires caused by the aging of wires and cables. How to reduce the fire Low smoke, halogen-free, flame retardant, and environmental protection have also become the development direction of the wire and cable industry. Among them, the demand for halogen-free low-smoke flame-retardant cable materials is increasing. At present, most of the production of halogen-free low-smoke flame-retardant cable materials is to add a large amount of magnesium hydroxide or magnesium hydroxide to polyolefin substrates to achieve flame retardancy. However, t...
