| 反光膜是由多层不同性能材料组成的层结构，不同的反光膜，其组成的层结构也是不同的。 图1是较早出现的玻璃珠反光膜的基本结构图，由图中可以看出，反光膜一般都是由表层（保护膜）、反射层（功能层）、基层（承载层）、胶粘层和底层（保护层）等多层不同物质组成的膜结构物体。 Reflective film is a layer structure composed of multi-layer materials with different properties. Different reflective film has different layer structure. Fig. 1 is the basic structure diagram of the glass bead reflective film which appeared earlier. It can be seen from the diagram that the reflective film is generally composed of surface layer (protective film), reflective layer (functional layer), base layer (bearing layer), adhesive layer and bottom layer (protective layer), etc. 反光膜的表层一般是由是透光性和耐候性能良好的树脂薄膜，反射层根据不同类型的反光膜其组成材料也各不相同，有微小玻璃珠、微棱镜或金属反光镀层等，基层多为树脂有机化合物制成的薄膜，胶粘层一般是环氧树脂胶，底层是厚纸做的保护层。 The surface layer of the reflective film is generally made of resin film with good transmittance and weatherability. According to different types of reflective film, the composition of the reflective layer is different. There are micro glass beads, micro prism or metal reflective coating, etc. The base layer is mostly made of resin-organic compounds, and the adhesive layer is generally epoxy resin adhesive. The bottom layer is a protective layer made of thick paper. 表4是各种反光膜的结构图，由此可见反光膜的种类不同，它的组成材料和结构也是各不相同。 反光膜的首要作用，就是改善交通标志的表面性能，使之能适应全天候状态的交通需要，提高道路安全运行条件。 Table 4 shows the structure of various reflective films. It can be seen that the types of reflective films are different, and their compositions and structures are also different. The primary function of reflective film is to improve the surface performance of traffic signs, so that they can meet the traffic needs of all-weather conditions and improve the road safety operation conditions. |
