Abstract

The invention relates to the technical field of compounding, and particularly discloses a TAC release base film and a preparation method thereof. The preparation method comprises the steps of adding cellulose triacetate, a plasticizer, an initiator, a stabilizer, an accelerant, a cosolvent, a lubricant and an anti-ultraviolet agent into a stirring barrel, stirring the raw materials through a stirring paddle, heating the stirring barrel at the same time, after the TAC raw materials are uniformly stirred and reach the degree of plastic film forming, pouring the TAC raw materials in the stirring barrel into a plastic film barrel through a lifting machine, then conveying the TAC raw materials in the plastic film barrel into a plastic film machine through a packing auger, continuously heating the TAC raw materials through the plastic film barrel, shaping the TAC raw materials into long strips through the plastic film machine, and extruding the TAC raw materials through a plurality of film pressing wheels so as to enable the TAC raw material to be thin enough. Through the composition of the components, the TAC release base film can weaken the occurrence of a rainbow pattern phenomenon, the reflectivity is reduced, the probability of glare generation is reduced, and the visual experience is enhanced.

Description

technical field [0001] The invention relates to the field of composite technology, in particular to a TAC release base film and a preparation method thereof. Background technique [0002] At present, with the continuous upgrading of the resolution of LCD screens, the screen protective film requires high transmittance and low reflectivity to meet a better visual experience, but the protective film in the current market is still dominated by PET substrates. [0003] However, since the refractive index of its own material cannot be optically matched with the hardening solution and glue, the phenomenon of rainbow pattern is serious, and the reflectivity reaches more than 12%, which produces a lot of glare and affects the visual experience. Reflective non-iridescent hardened protective film. Contents of the invention [0004] The purpose of the present invention is to provide a TAC release base film and its preparation method, aiming to solve the problem in the prior art that ...
