CN201841824U - Base plate - Google Patents

Abstract

The utility model discloses a base plate which comprises a luminous layer 1, a wear-resistant layer 2, a decorating layer 3 and a base material 4. The structure of the base plate is as follows: the wear-resistant layer of the base material is coated with the luminous layer; the luminous layer is formed by mixing rare-earth over-length afterglow light-storing phosphor with UV paint, and the material can emit light for more than 12 hours in darkness after absorbing visible light for 5 to 10 minutes, and can be used infinitely and repeatedly. The base plate mainly solves the problem when people write in the objective condition lack of a lighting apparatus or without adequate light, etc. People can put the base plate behind a piece of paper, light transmits the paper, and people can see the characters clearly. The invention has the advantages of being convenient for people to write, learn and work, and the like.

Description

A kind of backing plate

Technical field

The utility model relates to backing plate, particularly a kind of luminous backing plate.

Background technology

Known, along with the development of society, study has become the necessary ways that a personal growth is become a useful person.Yet the restriction that is lacked objective condition such as lighting apparatus, light be inadequate has sometimes brought all inconvenience for people's study and work.

Summary of the invention

At the problem that exists in above-mentioned, the utility model proposes the way of solution, its technical characterictic is:

Carry under enough a kind of situation that does not have light at night, can automatic continuous luminous backing plate.People can place backing plate the paper back, and the content on light just can be seen clearly through paper also can be write on paper easily.This backing plate not only can be convenient for people to reading study at night, can also play the effect of decorating surrounding environment.

For achieving the above object, the utility model adopts following technical scheme:

A kind of luminous backing plate has decorative layer and wearing layer at the upper surface of base material, scribbles the luminescent layer that is made of light-accumulated luminous powder of rare earth overlength afterglow and UV lacquer hybrid modulation on the wearing layer of base material.

The utility model scribbles the luminescent layer that is made of the light-accumulated luminous powder of rare earth overlength afterglow and UV lacquer (aliphatic poly ammoniacum ultraviolet-curing paint) hybrid modulation at the upper surface of backing plate, because XL type rare earth overlength afterglow light-accumulating luminous material absorbed visible light after 5-10 minute, in the dark sustainable luminous more than 12 hours, unlimited repeated use, life-span is up to more than 15 years, created safety and condition easily for like this people's work and study, and illuminate the room, for people provide a kind of beautiful living environment at night freely.This backing plate energy savings for people's study and work at night is put forward enough facilities, is beautified the environment again simultaneously, improves decorative effect.

Description of drawings

The present invention is described further below in conjunction with embodiment.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the schematic diagram of Figure 1A-A cutaway view, 1 luminescent layer wherein, 2 wearing layers, 3 decorative layers, 4 base materials.

The specific embodiment

The structure of a kind of luminous backing plate of the utility model is as shown in Figure 1 and Figure 2: mainly be made of base material 4, decorative layer 3, wearing layer 2, luminescent layer 1, wherein the upper surface at base material 4 has decorative layer 3 and wearing layer 2, scribbles the luminescent layer 1 that is made of light-accumulated luminous powder of rare earth overlength afterglow and UV lacquer hybrid modulation on the wearing layer 2 of base material 4.The light-accumulated luminous powder of XL type rare earth overlength afterglow is mixed in the UV lacquer, adopts current technology to cover with paint, lacquer, colour wash, etc. at floor upper surface.XL type rare earth overlength afterglow light-accumulating luminous material and UV lacquer are commercial product, and XL type rare earth overlength afterglow light-accumulating luminous material does not contain any radioactive substance, and is nontoxic.At present, this XL type rare earth overlength afterglow light-accumulating luminous material is widely used in fire-fighting, electric power, public security, aviation, traffic, health, tourist handicraft, civilian, false proof and luminous, reflective guideboard, doorplate, caution sign, sign board etc.This backing plate passes through the luminescent layer extinction by day, and realizes luminous at night by luminescent layer.The light-accumulated luminous powder material of this XL type rare earth overlength afterglow is that the electronics of rare earth ion 4f5d layer is under ultraviolet irradiation, produce the transition of electron energy level, dominant activator is heated in the hole that ground state level produces to discharge and gives valence band, captured by its activator, UV-activated stop after, the hole that coactivator is accepted is heated and is activated again, and discharge to valence band, again captured by dominant activator, the generation of the combination once more in hole just causes twilight sunset, because having deposited of coactivator played mitigation, thereby produces long-acting twilight sunset.

Claims (1)

1. luminous backing plate at the upper surface of base material (4) decorative layer (3) and wearing layer (2) again, is characterized in that: scribble luminescent layer (1) on the wearing layer (2) of base material (4).
