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 a luminescent flame-retardant adhesive. According to the preparation method, a P-containing flame retardant is added into an adhesive, the adhesive is immersed in a solvent, and filtering is carried out so as to obtain a sample; strontium carbonate and calcium oxide are mixed, grinded, dissolved, stirred, dried, and smashed so as to obtain a uniformly mixed strontium carbonate and calcium oxide powder; europium oxide, dysprosium oxide, and boric acid are mixed, and are added into the strontium carbonate and calcium oxide powder; an obtained mixture is delivered into a high temperature tubular furnace, and carbon powder is also introduced into the high temperature tubular furnace for calcination so as to obtain powdery luminescent particles; the sample obtained in the above step and the powdery luminescent particles are grinded and filtered, and are added into the adhesive for stirring so as to obtain the luminescent flame-retardant adhesive. The preparation method is extremely simple; the raw materials are easily available; the preparation method is suitable for large-scale preparation; the luminescent flame-retardant adhesive is capable of emitting fluorescence under light irradiation or after absorption of certain light; and application prospect in the fields such as fluorescence labeling and luminescent device is promising.
