Problems solved by technology

However, the reflective film obtained by the traditional plant coating process has poor reflective effect, and the reflective color is impure and uneven. It is difficult to form a reflective film with a specific color and uniform reflective effect, which leads to poor use in industrial design applications.

Abstract

The invention relates to the technical field of reflective film processing technologies, and particularly relates to a method for manufacturing a colorful reflective film with a blue front surface. The method comprises the following steps of: S1, manufacturing a bead-implanted base film, and implanting glass beads with the diameter of 35-55 microns and the refractive index of 1.9-1.95 on a PET film; S2, mounting the bead-implanted base film in an evaporation chamber of high-vacuum coating equipment; S3, placing a target material containing zinc sulfide in an evaporation tank of a vacuum electroplating machine; S4, completing the evaporation process of the whole roll of bead-implanted base film under the parameter conditions that the heating temperature of the target material is 1000-1200 DEG C, the air pressure in the evaporation chamber is 1.0 * 10 <-1> Pa to 2.0 * 10 <0> Pa and the linear speed of the bead-implanted base film is 50-90m / min; S5, after the evaporation process of the whole roll of bead-implanted base film is completed, closing all equipment, and adjusting the air pressure in the evaporation chamber to an air pressure value balanced with the external atmospheric pressure; and S6, opening the evaporation chamber. The obtained reflective film has a blue front surface, is purple when the visual angle is changed, and is uniform in reflective color and high in color purity.

Description

technical field [0001] The invention relates to the technical field of reflective film processing technology, in particular to a production method of a magic color reflective film with a blue front. Background technique [0002] The reflective film is a retroreflective material that has been made into a thin film and can be directly applied. Reflective films are usually made using glass bead technology, microprism technology, synthetic resin technology, thin film technology, coating technology or micro-replication technology. There are white, yellow, red, green, blue, brown, orange, fluorescent yellow, fluorescent orange, fluorescent yellow-green and other types of reflective film, which are widely used in industrial production. Among them, glass bead technology, as an important reflective film manufacturing process, has been widely used and developed. [0003] At present, the production process of reflective plant film generally first adheres glass beads on the glued subs...
