Irradiation crosslinking flexible corrosion-resistant low-smoke halogen-free composition as well as preparation method and application thereof

Abstract

The invention provides an irradiation crosslinking flexible corrosion-resistant low-smoke halogen-free composition as well as a preparation method and application thereof. The irradiation crosslinking flexible corrosion-resistant low-smoke halogen-free composition is prepared from the following raw materials in parts by weight: 10 to 15 parts of ethylene-vinyl acetate copolymer, 10 to 15 parts of flexibilizer, 15 to 20 parts of super-tough elastomer, 40 to 50 parts of magnesium hydroxide for chemical surface treatment, 0.7 to 1.5 parts of coupling aid, 3-6 parts by weight of an antioxidant, 2-3 parts by weight of a cross-linking agent, and 4-6 parts by weight of a lubricant. The invention also provides a preparation method of a cable. The irradiation crosslinking flexible corrosion-resistant low-smoke halogen-free composition can be used as a cable of an electric vehicle charging pile. The irradiation crosslinking flexible corrosion-resistant low-smoke halogen-free composition disclosed by the invention is high in temperature resistance grade and resistant to environmental corrosion.

Description

technical field [0001] The invention relates to a cable, in particular to a radiation-crosslinked, flexible, corrosion-resistant, low-smoke and halogen-free composition, which belongs to the technical field of cable preparation. Background technique [0002] With the rapid development of domestic electric vehicles, related supporting equipment has also ushered in rapid development. Among them, electric vehicle charging pile cables have also received high attention. The charging pile cable materials should mainly consider the following aspects: [0003] 1. Natural environment: Due to long-term exposure to the outdoors, electric vehicle charging cables will encounter various harsh natural environments during use, including large temperature differences between day and night, sunlight, weathering, humidity, acid rain, freezing and sea water, etc. , These natural environments will seriously affect the life and performance of the charging cable, and even reduce the reliability an...

Problems solved by technology

[0003] 1. Natural environment: Due to long-term exposure to the outdoors, electric vehicle charging cables will encounter various harsh natural environments during use, including large temperature differences between day and night, sunlight, weathering, humidity, acid rain, freezing and sea water, etc. , these natural environments will seriously affect the life and performance of the charging cable, and even reduce the reliability and safety of the charging cable, causing property damage and personal injury

[0004] 2. Man-made environment: During the use of the charging cable, due to its flexible use, it is inevitable that there will be artificial bending, twisting, dragging or even stretching, which will easily cause mechanical damage to the charging cable; at the same time, the charging cable may be artificially damaged. Soaking in the acid-base solution will affect the performance of the cable material and cause damage to the charging cable
