AI Technical Summary
Technical Problem
Existing MS adhesives are prone to photoaging and yellowing after use.
Method used
MS adhesive additives were prepared by esterification reaction using pentamethylpiperidinol, octadecadienoic acid dimer and diisopropylbis(dioctylpyrophosphate)titanate as the main raw materials. This process captures free radicals in the polymer degradation chain reaction and inhibits the photo-oxidation process.
Benefits of technology
It effectively inhibits photoaging and yellowing of MS adhesive, and improves the light stability and performance stability of MS adhesive.

Abstract
The application discloses MS glue, an MS glue additive and a preparation method of the MS glue additive, and the preparation method of the MS glue additive comprises the following steps: dissolving pentamethyl piperidyl alcohol in an organic solvent, heating, and stirring; adding octadecadiene acid dimer, and stirring; adding diisopropyl bis(dioctyl pyrophosphoric acyloxy) titanate, and stirring; heating, and extracting the solvent under reduced pressure to obtain a product. In the technical scheme, the MS glue additive can effectively capture free radicals in a polymer degradation chain reaction, thereby inhibiting a photo-oxidation process, and achieving a light stabilization purpose. Through evaluation, the additive can greatly reduce performance attenuation and yellowing of the MS glue under light aging.
