Manufacturing method for self luminescent membrane with shading light of back side and luminescence of front side and product produced by same

Abstract

The invention relates to a manufacturing method for a self luminescent membrane with shading light of a back side and luminescence of a front side and a product produced by the same. Components comprising alkaline earth aluminum-silicate are mixed to manufacture a self luminescent material membrane which is adhered to a paper base and can be taken down from the paper base for use. The manufacturing method comprises the following steps: superposing the self luminescent material membrane, a polyvinyl chloride white membrane, and a polyvinyl chloride light shielding black membrane in turn, compounding the self luminescent material membrane, the polyvinyl chloride white membrane and the polyvinyl chloride light shielding black membrane into a whole by rolling; and adhering one surface of the polyvinyl chloride light shielding black membrane in the self luminescent membrane to the paper base, and punching the paper base. The manufacturing method has the advantages that: on the basis of manufacturing the self luminescent material membrane by mixing the components comprising the alkaline earth aluminium-silicate, the back side of the self luminescent material membrane is compounded with the polyvinyl chloride light shielding black membrane to manufacture the self luminescent membrane with the functions of the shading light of the back side and the luminescence of the front side; and the self luminescent membrane can effectively cover the background of an adhered surface to make the background not appeared, improve the visual effect of the product, and can be widely applicable to manufacturing an adhesive film, an advertisement sticker, and other film products.

Description

technical field [0001] The invention relates to a method for producing a self-luminous material, in particular to a method for producing a self-luminous film with back light shielding and front light emission and a product thereof. Background technique [0002] Traditional self-luminescent materials mainly include sulfide-based luminescent materials and alkaline earth aluminosilicate-based luminescent materials. [0003] The stability of sulfide-based luminescent materials is poor, and it will decompose under strong ultraviolet radiation outdoors, and the brightness will decrease, and the luminescence duration of sulfide-based luminescent materials is short, only tens of minutes to several hours. If you want to extend the luminescence time And to increase the brightness, radioactive elements need to be added, but this will pollute the environment; [0004] Alkaline-earth aluminosilicate-based luminescent materials can emit visible light in a dark place after being irradiate...

Problems solved by technology

But this kind of material is all composed of organic materials, its hardness, heat distortion temperature, dimensional stability and shrinkage reduction are not very good, and its electrical insulation and flame resistance sometimes do not meet the requirements

[0008] In order to solve the shortcomings that alkaline earth metal aluminosilicates are not suitable for making film products such as sticking films or advertising stickers, the applicant of the present invention discloses a self-luminous material in i
