Embodiment 1

[0034] Example 1 (production of power cables)

[0035] An energy-saving and environment-friendly cross-linked polyolefin cable material, which is prepared from the following raw materials by weight: 85 parts of polyolefin as the first component, 15 parts of polyolefin as the second component, 0.3 parts of antioxidant, lubricating 0.05 parts of agent, 1.8 parts of cross-linking agent; the first component polyolefin and the second component polyolefin are the same polyolefin and are added twice by weight, which is low density polyethylene DJ210; antioxidant is 1076; lubricating The agent is fluorine lubricant; the crosslinking agent is DCP dicumyl peroxide.

[0036] The cross-linked polyolefin cable material prepared in Example 1 is white solid particles, the main technical indicators: the tensile strength is 16.2MPa, the elongation at break is 460%, and it is extruded at a temperature of 90-120°C with an extruder to produce electric power Cables, marine cables, mining cables...

Embodiment 2

[0039] Example 2 is the same as Example 1, except that the polyolefin is low-density polyethylene 2102TN00, and the antioxidant is 300.

Embodiment 3

[0041] Example 3 is the same as Example 1, except that the polyolefin is low-density polyethylene 2102TN00, and the lubricant is silicon-based lubricant.

Abstract

The invention provides an energy-saving and environment-friendly cross-linked polyolefin cable material. The energy-saving and environment-friendly cross-linked polyolefin cable material is prepared from the following raw materials in parts by weight: 85-95 parts of first component polyolefin, 5-15 parts of second component polyolefin, 0.3-0.5 part of antioxidant, 0.05-0.15 part of lubricating agent and 1.8-2.4 parts of crosslinking agent, wherein the two components adopt one polyolefin, namely low-density polyethylene, or EVA (ethylene-vinyl acetate), or POE (polyolefin elastomer); and the preparation method of the cable material comprises the following steps of: mixing the second component polyolefin, the antioxidant and the lubricating agent by virtue of a high-speed mixer, plasticizing and pelletizing the mixed material by virtue of a double-screw extruder at the temperature of 120-160 DEG C to obtain antioxidant and lubricating agent master batches, placing the antioxidant and lubricating agent master batches with the first component polyolefin into a shaking tank at the temperature of 80-90 DEG C, adding the crosslinking agent, carrying out pressurization until the pressure is 0.2Mpa, and permeating and absorbing the crosslinking agent for 10-20 minutes, so that the energy-saving and environment-friendly polyolefin cable material is obtained. The energy-saving and environment-friendly polyolefin cable material provided by the invention has double characteristics of energy conservation and environmental protection.

Description

technical field [0001] The invention relates to an energy-saving and environment-friendly cross-linked polyolefin cable material and a preparation method thereof, which is a cross-linked polyolefin cable material with energy-saving and environment-friendly effects, and does not contain lead (Pb) and cadmium which are harmful to the human body and the environment (Cd), mercury (Hg), hexavalent chromium (Cr) heavy metals, polybrominated biphenyls and their ethers and other substances that are contrary to environmental protection requirements, and their preparation process significantly reduces carbon dioxide emissions and energy consumption. Background technique [0002] The cross-linked polyolefin cable materials currently used all need to be extruded twice, which not only consumes a lot of energy, but also emits a lot of carbon dioxide, and the storage cost of intermediate products is high. With the development of my country's national economy, the demand for cable materials...
