Easy-peel highlighted silane crosslinking flame-retardant polyolefin insulation material, preparation method and application thereof

The invention relates to an easy-peel highlighted silane crosslinking flame-retardant polyolefin insulation material, a preparation method and application thereof, and aims to provide the polyolefin insulation material relatively good in mechanical property and electrical property. A prepared insulating layer of a low-smoke halogen-free flame-retardant cable is uniform in crosslinking, excellent in temperature endurance and easy to peel after being made into the cable, and in a high-speed paying-off situation, the cable surface is free of melt fracture, smooth, highlighted and easy to peel. The technical scheme is as follows: the polyolefin insulation material comprises an A material and a B material, wherein the A material comprises the following components: EVA, PE, a silane coupling agent, a primary antioxidant, an auxiliary antioxidant, an initiator, a compatilizer, a lubricating agent, a fire retardant and a filler; the B material comprises the following components: EVA, PE, a catalyst, a primary antioxidant, an auxiliary antioxidant, a compatilizer, a lubricating agent, a fire retardant and a filler.
