Reflective Material Development Process

Reflective material, also known as retroreflective material, is obviously seen by reflection of light at night or in a weak light; mainly for roads, Traffic Safety Clothing, cars, ships, waterways, stage, various channels and related Mechanical equipment.

Since the 1930s, in addition to the rapid use of a variety of science and technology industry to create a new type of retro-reflective material to reduce road traffic injuries as soon as possible, but also began to gradually start the application of retro-reflective technology to improve road safety conditions Research.

The earliest reflection of the phenomenon of animals in the night glowing eyes, inspired by the use of glass beads as a reflective medium, invented the luminescent material.

Most of the reflective material is composed of the surface layer (protective film), the reflective layer (functional layer), the base layer (bearing layer), adhesive layer and the bottom layer (protective layer) and other layers of different materials composed of membrane structure objects.

As shown in the following figure, is the earliest appearance of the glass beads reflective film of the basic structure, the reflective material of the surface is generally made by the light transmission and weather resistance of the resin film, the reflective layer according to different types of reflective film composition materials are also not The same, there are tiny glass beads, micro-prism or metal reflective coating, the base layer of resin for the organic compounds made of thin film, adhesive layer is generally epoxy resin, the bottom is thick paper to do the protective layer.

The primary role of the reflective film is to improve the surface performance of traffic signs, so that it can adapt to the all-weather state of the traffic needs, improve road safety operating conditions.

As the reflective properties of different types of the reflective film there are differences, so the specific application to the production of traffic signs, you need to set the function according to the logo and the purpose of the corresponding norms. The science of this application specification is regarded as an important component of traffic control and safety technology by professionals from all over the world. 

The reflective film is divided into: Buried Reflective Film, Sealed Reflective film, Micro-prism Reflective Film, Full prism Reflective Film, the structure as shown below.

Built-in reflective film and commonly known as “Engineering Grade” lens embedded reflective film, glass beads reflective film is the first class of products, the industry used to call the “engineering grade” series of reflective film, the positive brightness (0.2 º / -4 º) generally below 100cd / lx / m, the service life is generally 3 to 7 years, 3-7 years after the brightness retention value of at least 50% of the initial brightness value.

The lens-sealed reflective film is a durable glass bead-type reflective film, the industry used to call the “High Intensive Beads” reflective film, the internal vacuum support structure also due to temperature changes caused by signs of condensation on the issue of dew, so further Improve the reflective ability of the material.

High-grade high intensive beads reflective film life is generally 10 years, white film front brightness (0.2 º / -4 º) generally 250cd / lx / m above, 10 years after the brightness retention value of at least 80% of the initial brightness value, but At the same time, it is also due to the high-strength level of its own structure led to some difficult to overcome the product defects, such as product brittle and easy to tear, wrinkle, bubble, surface honeycomb protrusions, high energy consumption,

Micro-prism reflective film of the reverse reflection principle and engineering (lens embedded) and high-strength (lens-sealed) reflective film is different from the engineering grade and high strength grade reflective film are used glass beads reflection principle, and micro-prism reflective film reflection The principle is the use of micro-prism refraction and reflection.

The prismatic retroreflective film is a prismatic retroreflective material which is completed by using the prism structure. That is, it can remove the non-reflective part of the traditional micro-prism structure, so that all the reflective film can be composed of a prism structure which can realize the whole reflection. It combines the long-distance and large angle micro-prism reflective film of the two characteristics, while maintaining the positive brightness, easy to find long distances at the same time, increased in the 50-250 meters distance when the large incidence angle and observation angle of the reflective brightness The

The positive brightness of this full prism mirror is more than six times that of the engineering grade. The brightness of the white film (0.2º / -4º) is generally more than 600 cd / lx / m, which is more than twice that of the high strength level. (0.5º and 2º), the retroreflective performance is about two to four times higher.
