The invention discloses a UV cross-linked polyolefin reinforced EVA optical film and a preparation method thereof. The polyolefin resin of ethylene-vinyl acetate and ethylene-n-butene copolymer is used as a base material, and the ethylene-n-butene copolymer According to the total weight of EVA and polyolefin resin mixture base material is 100 parts, the UV curing polyolefin reinforced EVA optical film also includes the following by weight parts Raw materials: 0.05-5 parts of photoinitiator, 0.05-5 parts of thermal initiator, 0.05-5 parts of multifunctional crosslinking agent, 0.01-2 parts of antioxidant, 0.01-2 parts of light stabilizer, 0.1-3 parts of tackifier , 1 to 20 parts of tackifying resin. The UV-cured polyolefin reinforced EVA optical film of the present invention can replace the traditional OCA and LOCA optical adhesives. When the method is used for laminating the touch screen and the liquid crystal display, the process is simple, energy saving and environmental protection, no bubbles, can be reworked, and greatly improves the adhesiveness. Improve production efficiency, reduce lamination defect rate and production cost. |
