Abstract

The purpose of the invention is to provide a fabrication method for plastic light-reflecting base material high-weather-resistant fluorescence color patterns. According to the fabrication method for the plastic light-reflecting base material high-weather-resistant fluorescence color patterns, the plastic light-reflecting base material high-weather-resistant fluorescence color patterns are obtainedthrough the manner that high-concentration plastic cement fluorescence dye acrylic resin suspension liquid printing ink is directly printed on a plastic film material, and then hot-pressing molding is performed by a metal light-reflecting die after a layer of homogeneous plastic film material is covered on the printed plastic film material. Compared with an existing plastic light-reflecting basematerial fluorescence coloring technology, the fabrication method for the plastic light-reflecting base material high-weather-resistant fluorescence color patterns has the characteristics that the patterns have good weather resistance, printing is convenient, and complex and fine patterns are easy to fabricate.

Description

Technical field: [0001] The invention belongs to the technical field of fluorescent coloring of plastic reflective substrates, in particular to a method for manufacturing high weather-resistant fluorescent color patterns on plastic reflective substrates. Background technique: [0002] Fluorescent dyes absorb the ultraviolet rays in the incident light, and convert the ultraviolet rays into visible light of a certain wavelength through electronic energy level transitions. Due to the narrow wavelength range and high intensity of the reflected visible light, the substrate dyed by fluorescent dyes has a particularly dazzling appearance. characteristics. Fluorescent dyes are used in the coloring of plastic reflective substrates, which have stronger visual impact and longer viewing distances than ordinary dyes. [0003] There are many kinds of substances that can be used for fluorescent coloring of plastic reflective substrates, which can be generally divided into fluorescent pigm...
