Embodiment 1

[0020] Main material methyl methacrylate 66%, plasticizer butyl acrylate 32%, brightener non-polar SiO 2 Nano powder 1.5% and Al 2 o 3 Nano powder 0.35%, initiator azobisisobutyronitrile 0.15%. Methyl methacrylate, SiO 2 Nano powder, Al 2 o 3 Mix the nano-powder and stir until uniform; add the plasticizer butyl acrylate, the initiator azobisisobutyronitrile at 75°C, and add a small amount of release agent silicone oil at the same time, stir until uniform, and carry out the first stage of polymerization initiation . Fill the mold and carry out prepolymerization at 45°C for 28 hours. The temperature was raised vigorously to 75° C., and the polymerization was carried out intensively for 2 hours. Cool in the furnace and demould.

Embodiment 2

[0022] Main material methyl methacrylate 66%, plasticizer phthalyl dioctyl 32%, brightener non-polar SiO 2 Nano powder 1.5% and Al 2 o 3 Nano powder 0.35%, initiator azobisisobutyronitrile 0.15%. Methyl methacrylate, SiO 2 Nano powder, Al 2 o 3 Mix the nano-powder and stir until uniform; add the plasticizer o-phthalic dioctyl dioctyl ester, the initiator azobisisobutyronitrile at 75°C, and add a small amount of release agent silicone oil at the same time, stir until uniform, and carry out the second One-stage initiated polymerization. Fill the mold and carry out prepolymerization at 45°C for 28 hours. The temperature was raised vigorously to 75° C., and the polymerization was carried out intensively for 2 hours. Cool in the furnace and demould.

Embodiment 3

[0024] The main material is 66% methyl methacrylate, 32% plasticizer phthalate dibutyl, brightener non-polar SiO 2 Nano powder 1.5% and Al 2 o 3 Nano powder 0.35%, initiator azobisisobutyronitrile 0.15%. Methyl methacrylate, SiO 2 Nano powder, Al 2 o 3 Mix the nano-powder and stir until uniform; add the plasticizer o-phthalylene dibutyl ester, the initiator azobisisobutyronitrile at 75°C, and add a small amount of release agent silicone oil at the same time, stir until uniform, and carry out the second One-stage initiated polymerization. Fill the mold and carry out prepolymerization at 45°C for 28 hours. The temperature was raised vigorously to 75° C., and the polymerization was carried out intensively for 2 hours. Cool in the furnace and demould.

Abstract

The present invention belongs to the field of screw display technology. The preparation process of plasticized fexible high-brightness nano projection display screen material uses main material, plastcizer, nano powder brightnessing agent and initiator as material and includes mixing the main material and nano powder, adding brightneing agent and initiator at certain temperature for polymerization, filling the initiated polymerizing material into some mold, fast heating for violent polymerization, cooling in the reactor and demolding. The projection display screen material is flexible and windable and has high brightness, high resolution, high color fidelity and many other advantages and thus wide application foreground.

Description

technical field [0001] The invention relates to a preparation method of a plasticized flexible high-brightness nano projection display screen material, which belongs to the technical field of screen display. Background technique [0002] The applicant once applied for an invention patent titled "A Preparation Method of High Brightness and Wide Viewing Angle Free-scale Nano-scale Optical Material", the application number is 01115478.0, which describes the preparation of a high-brightness wide viewing angle free-scale nano-optical material The method adopts acrylic esters or styrene esters, plasticizers and nano-scale inorganic powders to be mixed and polymerized to directly synthesize optical materials with unique properties. The disadvantage is that the display screen made of this optical material has poor plasticity and is easy to break, which is not convenient for practical application. Contents of the invention [0003] The purpose of the present invention is to propos...
