Problems solved by technology

[0002] At present, the preparation of flame retardant adhesives adopts the method of directly adding solid powder flame retardants to the adhesive. After the adhesive is coated, there will be a large amount of granular residue on the adhesive surface, which will affect the appearance yield and affect the subsequent use. When using this kind of flame retardant adhesive, it is necessary to pre-treat the adhesive first, including grinding, high-speed stirring, etc. If the current treatment is not correct, the glue will still have granular residue after coating. Affect the coating yield. In order to reduce this pretreatment process, some flame retardant adhesive manufacturers add suspending agent to the adhesive. However, due to the insufficient physical stability of the added suspending agent, there is a certain degree of influence on the performance of the adhesive. influence, so this method is limited

Abstract

The invention discloses a preparation method of an upconversion fluorescent flame-resistant adhesive. According to the preparation method, a P-containing solid powdery flame retardant is added into an adhesive, and the adhesive is immersed in a solvent so as to obtain a fluorescent particle product; the fluorescent particle product and the P-containing solid powdery flame retardant processed via wetting are grinded and filtered, and an obtained filtering product is added into the adhesive for stirring so as to obtain the upconversion fluorescent flame-resistant adhesive. The prepared upconversion fluorescent flame-resistant adhesive possesses luminous effect, can be used on traffic clothing, dangerous road, and places with warning signs at night, and is capable of providing great convenience; coating yield rate of luminous adhesive is increased, and pretreatment technology of the upconversion fluorescent flame-resistant adhesive in application is reduced; and adding of suspending agent in the adhesive and adverse influence on adhesive solution performance are avoided.
