U.S. Patent No. 4,104,102 describes the production process of reflective film in detail. It adopts the process of focusing layer composite, which is difficult to realize in large-scale production, and the yield is low
The production of domestic reflective film mostly adopts the process of coating the reflective layer first and then compounding with glass beads, such as patent 96225924.1. The reflective film formed by this process has low brightness, especially the retroreflection coefficient at large angles is low, and it is difficult to carry out large-scale industrial production

Embodiment Construction

[0014] Such as figure 1 The shown highly flexible acrylic reflective film of the present invention consists of a surface resin layer 1, an adhesive layer 2, a single layer of closely arranged glass bead layer 3, a focusing paint layer 4, a metal reflective layer 5, a metal protective layer 6, a pressing The sensitive adhesive layer 7 and the anti-adhesive layer 8 are compositely bonded, and the surface resin layer 1 is provided with a protective backing layer 9 . The surface resin layer 1 is a transparent resin film with a thickness of 15-70 microns coated with high weather resistance multi-component acrylic resin, unsaturated polyester resin or polyurethane resin, or a mixture of the above materials. The focusing coating 4 is a spherical focusing coating 4 with a thickness of 5-10 microns and concentric with the spherical bottom surface of the glass microspheres 3 . The metal reflective layer 5 has a thickness of 3-5 microns. The metal protective layer 6 has a thickness of ...

Abstract

A reflecting high-flexibility acrylic film is composed of surficial resin layer with protective liner layer, adhesive layer, closely arranged glass microbead layer, focusing paint layer, metallic reflecting layer, metallic protecting layer, pressure sensitive adhesive layer and antisticking layer. Its preparing process is to adhere said layers sequentially.

Description

technical field [0001] The invention relates to the technical field of directional reflective materials, in particular to a novel high-flexibility acrylic reflective film and a manufacturing method thereof. Background technique [0002] Reflective materials were first successfully developed by 3M Company in the United States in the 1940s. After nearly 70 years of development, they have now expanded from the initial use in the field of road transportation to railways, shipping, electric power, mining, advertising, cities, decorations and other fields. According to their different retroreflection principles, the reflective film can be divided into two categories: glass bead type and micro prism type. Among them, the reflective film using glass bead type is divided into flexible grade, engineering grade and high strength grade according to its physical and reflective properties. The reflective performance of the flexible grade reflective film is low, but it has good flexibility...
