Novel anti-ultraviolet-ray polyolefin material

Abstract

The invention relates to a novel anti-ultraviolet-ray polyolefin material, which comprises the following raw materials by weight: 40-50% of an ethylene-vinyl acetate copolymer, 0.1-1% of an anti-rat and anti-ant agent, 0.1-3% of an anti-UV compound agent, 0.1-3% of aluminum hydroxide, 0.1-3% of an antioxidant, and 40-60% of low density polyethylene. The novel anti-ultraviolet-ray polyolefin material of the present invention has characteristics of good flame retardancy, no smoke, no toxicity, rat-ant resistance, ultraviolet ray resistance and aging resistance.

Description

technical field [0001] The invention belongs to the field of material science and technology, and in particular relates to a novel anti-ultraviolet polyolefin material. Background technique [0002] The current construction of optical cables, power cables, and coaxial cables often adopts several methods such as bare direct placement, overhead, buried, and laying, and the sheath material is generally made of ordinary PE materials. However, ordinary PE sheath materials have poor anti-ultraviolet and anti-biting functions such as termites, mice, squirrels or hares; when the damaged cable sheath material is bitten and destroyed, "small holes" will appear, causing the cable to be damp or soaked in water. , thus causing accidents such as telecommunication interruption, leakage and short circuit. The construction party usually uses a plastic tube or a steel (aluminum) tube to protect the outside of the cable; the cable manufacturer uses a metal sheath layer composed of a thin stee...

Problems solved by technology

However, ordinary PE sheath materials have poor anti-ultraviolet and anti-biting functions such as termites, mice, squirrels or hares; when the damaged cable sheath material is bitten and destroyed, "small holes" will appear, causing the cable to be damp or soaked in water. , thus causing accidents such as telecommunication interruption, leakage short circuit, etc.

The construction party usually uses a plastic tube or a steel (aluminum) tube to protect the outside of the cable; the cable manufacturer uses a metal sheath layer composed of a thin steel (aluminum) strip inside the cable, and some manufacturers use armoring for the cable core, etc. A variety of physical protection countermeasures, but all have little effect
