Preparation of long afterglow luminescent flame retardant coatings

Preparation method
The components except the long-afterglow luminous powder are mixed evenly with a stirring device, and then the long-afterglow luminous powder is added in the case of slow stirring, stirring for a period of time and then quickly stirring until uniform.

Raw material compatibility
The mass proportion range of each component of this product: high chlorinated polyethylene (30%)20~40; Chlorinated rubber 1 ~ 5; 70% chlorinated paraffin 3~8; 50% chlorinated paraffin 2 to 6; Antimony trioxide 2~5; Dispersant 0.1 ~ 0.5; Fumed silica 0.5~3; Heavy fragrance channel 5~10; Butyl acetate 2 ~ 5; Long afterglow luminescent powder 20 ~ 50.

Application: The long afterglow flame retardant coating can be used in civil air defense engineering, skyscrapers, large municipal buildings, subways, mines and other emergency escape indication signs and low-light lighting system and architectural art drawing, decoration and other aspects.

Product characteristics
The technology is simple, and the prepared long afterglow luminescent flame retardant coating has the characteristics of bright and lasting, different color afterglow, and has the flame retardant function. With sunlight or sunlight irradiation of -30rnin, its afterglow can last for more than 5~12h, and its flame retardant temperature can reach 200℃. At the same time, the preparation process of this long-afterglow luminescent flame retardant coating is simple, non-radioactive, and will not cause harm to the environment.
