Oil-resistant low-smoke halogen-free flame-retardant polyolefin cable material and preparation method thereof

Abstract

The invention discloses an oil-resistant low-smoke halogen-free flame-retardant polyolefin cable material and a preparation method thereof. The cable material comprises the following components in parts by weight: 80-90 parts of recycled low-smoke halogen-free plastic alloy, 5-10 parts of organic silicon grafted polyethylene, 8-10 parts of an ethylene-vinylacetate copolymer, 20-30 parts of an inorganic flame retardant, 1-3 parts of a modifying agent, 2-5 parts of an interface compatibilizer, 1-1.5 parts of an irradiation cross-linking agent, 0.3-0.5 parts of an anti-oxidant, 0.5-1 part of a lubricating agent and 3-5 parts of a color masterbatch. The oil-resistant low-smoke halogen-free flame-retardant polyolefin cable material and the preparation method thereof disclosed by the invention have the benefits that the oil resistance of products can reach the class-III oil resistance grade regulated in TB / T 1484.2-2010; through the modified inorganic flame retardant, the flame retardance of the cable material is greatly improved; the organic silicon grafted polyethylene ensures the oil resistance of the cable material. Through performing compound modification on the recycled plastic alloy, the oil-resistant low-smoke halogen-free flame-retardant polyolefin cable material is efficiently prepared, so that not only is the production cost reduced, but also wastes are re-utilized, and sources are saved.

Description

technical field [0001] The invention belongs to the technical field of cable materials, and in particular relates to an oil-resistant, low-smoke, halogen-free, flame-retardant polyolefin cable material and a preparation method thereof. Background technique [0002] The existing oil-resistant cable materials generally use EPDM, nitrile rubber, and EVM to compound flame retardants and vulcanizing agents as raw materials, and the oil-resistant materials prepared can meet the requirements of oil resistance. , but there are disadvantages of low tensile strength and poor low temperature performance. Contents of the invention [0003] Purpose of the invention: Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide an oil-resistant, low-smoke, halogen-free, flame-retardant polyolefin cable material, and the oil resistance of the product can reach Class III specified in TB / T1484.2-2010 Oil resistance grade. Another object of the present in...
