Title:
DIALKYL PHOSPHINIC ACID HYBRID SALT, PREPARATION METHOD THEREFOR, AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2024/060020
Kind Code:
A1
Abstract:
The present application discloses a dialkyl phosphinic acid hybrid salt, a preparation method therefor, and use thereof. The dialkyl phosphinic acid hybrid salt is selected from at least one of compounds having a chemical formula represented by formula (I). The dialkyl phosphinic acid hybrid salt with the composition represented by formula (I) provided by the present application features small addition amount, high flame retarding efficiency on various high polymer materials, and good thermal stability. The dialkyl phosphinic acid hybrid salt not only overcomes the defect that diethyl phosphinate has low flame retarding efficiency on high polymer materials, but also overcomes the defects that long-chain dialkyl phosphinate has low thermal stability and produces large smoke during combustion, and therefore can be widely applied to flame retarding of polymer materials that need to be processed under high temperature.
