Abstract

The invention discloses an EVA (ethylene-vinyl acetate) luminous film which is prepared by mixing 30-90% of EVA (KA-31), 5-50% of EVA (MA-10), 5-15% of fluorescent powder, 0.1-3% of 3- isobutenyl propyl triethoxysilane, 0.01-1% of tri(nonylphenyl) phosphite, 0.1-0.2% of 2-hydroxy-4-octyloxy diphenyl ketone and 0.1-1% of bis (2,2,6,6-tetramethyl-4-piperidyl) sebacate, as the fluorescent powder is added in the EVA film, the prepared EVA luminous film is high in brightness and long in service life, the luminous effect cannot decline easily, and the EVA luminous film is widely used to home decorations, building composite materials and the like.

Description

technical field [0001] The invention relates to an EVA film, in particular to an EVA luminous film. Background technique [0002] Laminated glass is a very ideal variety of multi-purpose glass. It can not only protect the safety of people and property, but also maintain the beauty and transparency of the glass. At the same time, it can also reduce noise, control sunlight and shield at least 99% of harmful ultraviolet rays. In addition, insulating glass made of laminated glass increases thermal insulation. Therefore, laminated glass is an excellent solution to the problem of safety protection. In recent years, it has been widely used in high-rise buildings, automobiles and public facilities. [0003] However, the luminous films currently used for decoration have some defects. For example, after the film is bonded to the building, the luminous effect decays quickly, the life is short, and the brightness is low, which cannot effectively solve the problem of using the film un...
