Title:
NANO MOLDING COMPOSITE MATERIAL AND PREPARATION METHOD THEREFOR, HOUSING ASSEMBLY, AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/115096
Kind Code:
A1
Abstract:
The present application provides a nano molding composite material, comprising the following components: a crystalline resin, a glass fiber, a toughening agent, an antioxidant, and a lubricant. The crystalline resin comprises one or more of syndiotactic polystyrene, polyethylene glycol terephthalate, and modified polyphenylene oxide. The problems that nano molding materials generally have the defects of a high dielectric constant and a high dielectric dissipation factor, seriously affect the bandwidth of antennas and cannot meet requirements of long wavelength, high frequency and large capacity can be solved. The present application further provides a preparation method for the nano molding composite material, a housing assembly, and an electronic device.
