Method for making reflective and self-luminous substrate

A method for making a reflective and self-luminous substrate, comprising:

• a first step of making a reflective layer;
• a second step of heating;
• a third step of making a luminous layer;
• and
• a fourth step of cooling;
• wherein:
• the first step includes pressing a macromolecular material by a calendar device to form a successive reflective layer which is transparent and has determined flexibility and elasticity;
• the second step includes placing and heating the reflective layer in a heating device during a time interval ranged from three to fifteen minutes to a preset temperature value;
• the third step includes:
• a first substep of preparing material;
• a second substep of painting;
• and
• a third substep of drying;
• the first substep includes placing and stirring luminous powder and fluorescent powder in a stirrer at a high speed so that the luminous powder and the fluorescent powder are mixed evenly to form a luminous blank;
• the second substep includes evenly painting the luminous blank on the reflective layer;
• the third substep includes placing the reflective layer and the luminous blank in a dryer and drying the luminous blank at a predetermined temperature value to form a luminous layer which has luminous and fluorescent effect;
• the fourth step includes cooling the reflective layer and the luminous layer to produce a substrate including the reflective layer and the luminous layer;
• the substrate has reflective and self-luminous features;
• and
• when a light source irradiates the luminous layer of the substrate, the luminous layer containing the luminous powder and the fluorescent powder can absorb light from the light source, so that when the light source disappears, the luminous layer of the substrate emits light locally or completely in a dark environment by reflection of the reflective layer of the substrate.
