Abstract

The invention discloses a luminescent material for an electric signboard. The material is prepared from the following raw materials in parts by weight. 65 to 75 parts of isophthalic acid type unsaturated polyester resin, 15 to 20 parts of polyurethane resin, 40 to 50 parts of a light storage material, 3 to 10 parts of zinc stearate, 0.5 to 1.2 parts of magnesium oxide, 5 to 15 parts of glass fibers, 0.5 to 2 parts of hydroxyl silicone oil, 0.2 to 0.6 part of an ultraviolet light absorber, 0.5 to 1 part of an initiator, 0.1 to 0.5 part of a drier and 15 to 25 parts of a solvent. The luminescentmaterial for the electric signboard is good in self-luminous effect and excellent in wear resistance and high temperature resistance.

Description

Technical field [0001] The invention belongs to the field of electric power technology, and specifically relates to a luminescent material for electric power identification signs and a preparation process thereof. Background technique [0002] Power signboards mainly provide people with direction and information recognition. They are not only required to be strong and durable, but also have a certain lighting effect. Existing power signboards are corroded or worn under long-term wind and sun environment. It becomes blurred and needs to be replaced regularly, and the luminescent material in the luminescent layer of the signboard has poor reflective performance and poor visual effect during the day. It is difficult to identify and observe during line inspections or emergency repairs at night, and it is easy to cause accidental collision. [0003] The Chinese invention patent application with publication number CN107652804A discloses a luminous visible smart sign and its preparation m...
