Embodiment Construction

[0009] A production process of a reflective curved surface focusing layer with the same center of a reflective film, which has the following process: a. Coating, surface resin coating adhesive, glass microspheres are bonded to the surface resin through electrostatic cloth beads, and pressed to form The bottom of the glass beads is on the same plane of the glass bead layer, and the water-based environmentally friendly modified acrylic paint or polyurethane paint is coated on the bottom of the beads. The coating method is roller coating, spraying or wiping. The refractive index of the glass beads 1.9-2.25, the particle size is 250 mesh to 500 mesh, according to the refractive index and particle size distribution of glass beads, water-based environmentally friendly modified acrylic coatings or polyurethane coatings with a solid content of 16-46% are selected. UV absorber, leveling agent, defoamer, wetting agent are added in the modified acrylic paint or polyurethane paint, and the...

Abstract

A process for preparing a reflecting curved surface focus layer with the same circle center of reflecting film includes coating adhesive on surface resin and binding glass micro ball on surface resin by static ball lay out, pressing glass micro ball to let its bottom on the same plane of glass micro ball layer then coating modified aryloid coating on micro ball bottom; drying coated semi product through drying channel to form curved surface focus layer with the same circle center of glass micro ball at micro ball bottom naturally.

Description

technical field [0001] The invention relates to a production process of a concentric reflective curved surface focusing layer of a reflective film. Background technique [0002] In recent years, the construction of expressways and national roads in my country has developed rapidly, and the requirements for traffic signs and motor vehicle licenses, such as train speed-up, have become higher and higher, especially for their reflective performance. The retroreflective performance is good. At present, the domestic reflective film is mostly prepared by the process of first coating the reflective layer and then planting beads. The reflective film prepared by this process cannot meet the requirements in terms of reflection intensity and retroreflection coefficient at large angles. Contents of the invention [0003] The object of the present invention is to provide a production process for the concentric reflective curved surface focusing layer of the reflective film, so as to over...
