Title:
COMPOSITE COATING, PREPARATION METHOD THEREFOR AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2024/040661
Kind Code:
A1
Abstract:
The present invention relates to the technical field of flame-retardant polymer materials, and particularly to a composite coating, a preparation method therefor and a use thereof. The present invention provides a composite coating, comprising n unit coatings which are stacked, wherein n≥1; each unit coating comprises a first coating and a second coating which are sequentially stacked; both the first coating and the second coating comprise water-soluble polymer compounds; the water-soluble polymer compounds comprise electropositive water-soluble polymer compounds or electronegative water-soluble polymer compounds; the water-soluble polymer compounds in the first coating and the second coating have opposite electrical properties; the first coating and/or the second coating further comprise M(OH)(OCH3), wherein M comprises one or more of Co, Ni, Fe, Mg, Al and Zn. The composite coating provided by the present invention has excellent flame-retardant properties.
