Title:
THERMALLY CONDUCTIVE HALOGEN-FREE FLAME-RETARDANT INSULATING POLYPROPYLENE FILM AND PREPARATION METHOD
Document Type and Number:
WIPO Patent Application WO/2023/201909
Kind Code:
A1
Abstract:
The present invention discloses a thermally conductive halogen-free flame-retardant insulating polypropylene film and a preparation method. The film comprises the following starting materials: polypropylene, a thermally conductive filler, an antioxidant, a silane coupling agent, a flame retardant, and a flexibilizer. The thermally conductive halogen-free flame-retardant insulating polypropylene film provided herein, under the action of the thermally conductive filler, has thermal conductivity. The starting materials used are all insulating materials, providing good insulating performance for the film. The flame retardant used is a halogen-free flame retardant containing two functional groups of phosphorus and silicon, which features excellent flame retardant effects and meets the current requirements of society for the development of environmentally friendly flame retardants. The flame retardant is a polymer with a certain degree of polymerization, has good compatibility with a polymer matrix, and is not prone to migration and exudation from the matrix, such that the flame retardant can be dispersed in the matrix more uniformly to exert better flame retardant effects. The flame retardant has flame retardant effects and is also a filler, and can be used to improve the processing performance, the mechanical properties, and the like of the film.
