Abstract

Disclosed is an anti-UV LED light decay, radiation cross-linked polyethylene insulating material, and a preparation method thereof. The raw materials comprise a matrix resin, a specific photoinitiator, a specific photoinitiator aid, and a specific multi-functional group crosslinking aid. The matrix resin is composed of polyethylene resin, a light-transmitting resin, and an ethylene-vinyl acetate copolymer. The preparation method comprises weighing each raw material in accordance with a formula, mixing and stirring the polyethylene resin, the specific photoinitiator, the specific photoinitiator aid and the specific multi-functional group crosslinking aid to prepare a premix, mixing the premix with the remaining raw materials, and extruding same to form and obtain an insulating material. The insulating material of the present invention can be processed at a low temperature, and has a sufficient degree of crosslinking without the need to reduce the extrusion speed.

Description

technical field

[0001] The invention belongs to the field of ultraviolet light cross-linked polyethylene insulating materials, and in particular relates to an anti-UV LED light decay radiation cross-linked polyethylene insulating material and a preparation method thereof. Background technique

[0002] With the continuous progress of science, a new UVLED ultraviolet light source based on LED point light source has emerged. This light source is more energy-saving, environmentally friendly, mercury-free, can work under low temperature conditions, and has a longer service life. Specifically, compared with traditional high-pressure mercury lamps, UVLED has many characteristics: 1. Longer service life, about 35,000 hours; 2. Low energy consumption. Compared with traditional high-pressure mercury lamps, it can save energy by 90%; 3. Cold light source, no infrared heat radiation; 4. No mercury, safe and environmentally friendly; 5. Stable light output; 6. Low maintenance cost, more ...
