Problems solved by technology

[0002] There are various adhesives produced in the prior art. In the prior art, there is a kind of luminous adhesive that uses flash powder, but it lacks luminescent powder that can emit light by itself, so it is difficult to achieve the purpose of energy storage and luminescence. From different angles, there is not much difference in color
The existing adhesives used for road sign warning signs and various safety warning signs rely on lights to reflect light at night to remind passers-by or use safety lights, which is very inconvenient

Abstract

The invention discloses a luminescence gel, which is characterized by comprising the following raw materials, by weight: 5-20% of a polymer resin, 0.1-15% of flash powder, 1-15% of an excipient, 3-40% of luminescence powder, and 20-85% of water. The preparation method comprises the following steps: (1) adding a polymer resin and water to a reaction kettle, heating to a temperature of 60-95 DEG C, and stirring for 30-90 min; (2) adding an excipient to the reaction kettle, carrying out thermal insulation stirring for 10-40 min at a temperature of 60-95 DEG C, and stopping heating, such that the material is naturally cooled along with stirring; (3) adding luminescence powder and flash powder to the reaction kettle, and stirring for 10-40 min to obtain a mixture; and (4) carrying out filling packaging on the obtained mixture to obtain the finished product. According to the present invention, the long time luminescence function under a dark state of the luminescence gel can be achieved through absorbing natural light or artificial light.

Description

technical field [0001] The invention relates to a stationery product, in particular to a luminescent glue and a preparation method thereof. Background technique [0002] There are various adhesives produced in the prior art. In the prior art, there is a kind of luminous adhesive that uses flash powder, but it lacks luminescent powder that can emit light by itself, so it is difficult to achieve the purpose of energy storage and luminescence. From a different angle, there is not much color difference. Existing adhesives that are used for road sign warning signs and various safety warning signs all rely on lights to reflect light at night to remind passers-by or use safety lights, which is very inconvenient. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art, and provide a luminescent glue that can realize self-luminescence for a long time in a dark state by absorbing natural light o...
