Abstract

The invention discloses reflective black reflective film and a production process thereof. The black reflective film comprises a surface layer, a microprism layer, a black base layer, a reflective layer, a supporting enhancement layer, a gum layer and a release paper layer in sequence from top to bottom, wherein microprism crystalline powder is densely arranged in the microprism layer, glow powderis uniformly distributed in the black base layer, the reflective layer comprises glass beads and an aluminum-coated layer, and the supporting enhancement layer is a hard acrylic resin layer. The application range of the reflective film is enlarged, the reflective black reflective film is provided, the reflective performance of the reflective black reflective film is good, the black base layer issandwiched between the microprism layer and the reflective layer, the black base layer can obtain larger retro-reflecting coefficients through the combined action of a microprism and the glass beads,thereby having a better reflective effect, and breaking the limitation that traditional black cannot reflect light.

Description

technical field [0001] The invention belongs to the field of reflective films, in particular to a reflective black reflective film and a production process thereof. Background technique [0002] Reflective film is a retroreflective material that has been made into a film and can be directly applied. Usually white, yellow, red, green, blue, brown, orange, fluorescent yellow, fluorescent orange, fluorescent yellow-green, and fluorescent red and fluorescent pink abroad. However, there are very few black reflective films on the market at present, or the traditional black reflective films have low reflective coefficients, which greatly limits the application of reflective films. Contents of the invention [0003] The purpose of the present invention is to overcome the above problems in the prior art, and provide a reflective black reflective film and its production process. The black reflective film produced by this process has better reflective performance, which expands the ...
