Embodiment Construction
[0023] The present invention is illustrated by taking straight ahead and right-turn shared lane road traffic signs as an example. Depend on figure 1 and figure 2 It can be seen that the high-brightness and long-lasting luminescent signboard of the present invention includes a substrate 1, a reflective film 2 is provided on the front of the substrate 1, a graphic silk screen layer 3 is provided on the reflective film 2, and sodium distyrene biphenyl disulfonate is arranged on the silk screen layer 3 The fluorescent layer 4, the remaining reflective film 2 and the fluorescent layer 4 are provided with an anti-radiation UV varnish protective layer 5.
[0024] The signboard of the present invention is manufactured according to the shape, size and graphic design required by the relevant national industry standards. The graphic is a word, a picture or a combination thereof. The specific preparation method is:
[0025] a) Preparation of luminous paint: first weigh 2.8kg of crist...

The invention discloses a high-brightness long-afterglow luminescent indicator plate and a preparation method thereof. The preparation method comprises the following steps: pasting a reflective film on the front face of a substrate; spray-printing a luminous coating on the reflective film so as to form a graphical silkscreen; coating a diphenylethene-biphenyl sodium disulfonate fluorescent layer on the silkscreen; and coating a radiation-proof UV (ultraviolet) gloss oil protective layer on the reflective film which is not covered with graphs as well as the fluorescent layer. The preparation method of the luminous coating comprises the following steps: firstly pouring one third of a cristobalite transparent filler into a mixing tank, adding special light-transmitting resin, PE (polyethylene) resin and dioctyl phthalate (DOP), and then evenly stirring; and sequentially adding pigment, a nano rare-earth luminescent material, glass microspheres and the residual cristobalite transparent filler while stirring, and then evenly stirring for use. For the high-brightness long-afterglow luminescent indicator plate obtained by the preparation method, the brightness can reach 19,800mcd / m<2>, luminescence time can reach 10-14 hours in the case of single light absorption for 30 minutes, the minimum retro-reflection coefficient is cd.1*x<-1>m<-2> for various colors, the observation angle is 0.2 degree, and the incident angle is -4 degree. The high-brightness long-afterglow luminescent indicator plate has the advantages of endless cyclic energy storage, aging resistance, corrosion resistance, flame retardance, no toxicity, no harm, no radiation and energy conservation and is environmentally-friendly.
Description
technical field [0001] The invention relates to an energy-storage luminous signboard, in particular to a high-brightness, long-afterglow luminous signboard, and also relates to a preparation method of the luminous signboard. Background technique [0002] As an important medium in the field of personal and property safety, such as safety, traffic, warning, reminder, fire protection, signage plays an indispensable role in production and life. From the perspective of warning and prompting, signs are usually required to be eye-catching, easy to understand and durable. At present, most of the signs are made with ordinary reflective film technology, and the display effect is average. The display effect is even worse in dark environments such as night and rainy and foggy weather. It needs strong light to distinguish. Due to the rough manufacturing process and poor materials, many signs began to fade, rust, and image peeling off soon after they were put into use. Under the con...
