Abstract

The invention relates to a preparation process of a PET (Polyethylene Terephthalate) film with high reflective brightness capable of replacing a glass mirror. The preparation process comprises the following steps of: S1, preparing a first PET film; S2, preparing a second PET film; S3, adding a third raw material in a preset proportion into a reaction kettle, stirring and melting to prepare a bonding liquid, and adding the bonding liquid into a second storage box; S4, conveying the first PET film in the S1 into bead planting equipment, and enabling a control unit to start the bead planting equipment to prepare a reflective layer on the upper surface of the first PET film; and S5, pressing the second PET film in the S2 to the reflective layer, and drying and rolling to obtain a film with high reflective brightness. According to the invention, the distribution condition of the glass beads can be accurately mastered, so that the light reflection intensity of the reflective layer can be accurately mastered, the light reflection intensity of the reflective layer is more effectively ensured, and the film quality is improved at the same time.

Description

technical field [0001] The invention relates to the technical field of film preparation, in particular to a preparation process for a PET film with high reflective brightness that can replace glass mirrors. Background technique [0002] Reflective film is a film with a special structure that uses optical principles to retroreflect light back to the light source. PET reflective film is a new high-performance composite reflective material formed by combining the reflective layer formed by glass beads and PET polymer materials by a special process. It is widely used in billboards with reflective requirements, traffic reflective Signs (reflective road signs, reflective isolation belts, reflective car number plates), reflective police uniforms, industrial safety signs, etc. In the prior art, when preparing PET reflective film, when preparing the reflective layer, the depth of glass beads sinking into the bonding layer is insufficiently grasped, resulting in uneven distribution o...
