Title:
PLASTIC COMPOSITE MATERIAL CAPABLE OF BEING POLISHED AND CONNECTED TO METAL, AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2020/140306
Kind Code:
A1
Abstract:
The present invention relates to a plastic composite material capable of being polished and connected to metal, and a preparation method therefor. The composite material comprises, in parts by weight, the following components: PBT: 50-80; GF: 10-50; nano titanium dioxide: 1-5; a dispersing fluid medium: 3-10; compatibilizer: 1-8; a toughening agent: 5-10; an antioxidant: 0.1-1; and a lubricating agent: 0.1-1. The preparation method therefor comprises: (a) mixing the PBT resin, the nano titanium dioxide, the toughening agent, the compatibilizer, the antioxidant, and the lubricating agent in a mixer; and (b) subjecting the mixture obtained in step a to blending granulation by means of a double-screw extruder, laterally feeding the GF, and performing melt extrusion and granulation to obtain the plastic composite material. Compared with the prior art, the plastic composite material provided by the present invention has high affinity with metal and excellent post-processing polishing performance by adding a compatibilizer by means of a special process.
