Title:
ENVIRONMENTALLY-FRIENDLY FLUOROPOLYMER CONCENTRATED AQUEOUS DISPERSION, PREPARATION METHOD THEREFOR AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/142947
Kind Code:
A2
Abstract:
An environmentally-friendly fluoropolymer concentrated aqueous dispersion, a preparation method therefor and an application thereof. The fluoropolymer concentrated aqueous dispersion disclosed herein comprises fluoropolymer particles dispersed in an aqueous solvent and a polyvinylpyrrolidone-based polymer represented by formula (I). The presence of the polyvinylpyrrolidone-based polymer represented by formula (I) enables the provided fluoropolymer concentrated aqueous dispersion to have the advantages of low viscosity and good stability, and the polyvinylpyrrolidone-based polymer represented by formula (I) has good biodegradability and water solubility, and is environmentally-friendly. The provided fluoropolymer concentrated aqueous dispersion can be used for producing a fluoropolymer anti-dripping agent, and impregnating porous glass and porous metal, or served as a dielectric coating, and has characteristics such as good appearance and low conductivity.
