Title:
HIGH-TEMPERATURE SELF-CROSSLINKING FLUORINE-CONTAINING POLYARYLETHERKETONE AND PREPARATION METHOD THEREFOR, AND COATING AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/216537
Kind Code:
A1
Abstract:
The present invention relates to the technical field of polyaryletherketones, and discloses a high-temperature self-crosslinking fluorine-containing polyaryletherketone and a preparation method therefor, and a coating and a preparation method therefor. A molecular chain of the high-temperature self-crosslinking fluorine-containing polyaryletherketone comprises two cross-linking groups, namely a styryl and a thioether group; and the structural formula thereof is, wherein the value range of m is 1-40% (m + n), the value range of n is 60-99% (m + n), and R is a group of hexafluorobisphenol A where a phenolic hydroxyl group is removed. The fluorine-containing polyaryletherketone comprising the two groups can be dissolved in a conventional organic solvent to prepare a coating or paint, is linear and does not undergo a cross-linking reaction at a low temperature, and undergoes a cross-linking reaction during a high-temperature curing process after coating so as to form a polymer coating having a cross-linked structure, such that a coating with a surface having good damp-heat resistance, wear resistance and a low friction coefficient is provided, the production cost can be reduced, and an enameled wire is guaranteed to still maintain good electrical insulation in a high-temperature, high-pressure and high-humidity severe working environment.
