Title:
POLYMERIC ALLOY MATERIAL, PREPARATION METHOD THEREFOR, AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2024/066600
Kind Code:
A1
Abstract:
A polymeric alloy material, a preparation method therefor, and use thereof. The polymeric alloy material comprises 50-90 parts by weight of polycarbonate, 10-50 parts by weight of polyethylene terephthalate, 1-8 parts by weight of a modified mineral filler, and 0.5-1 part by weight of an interesterification inhibitor. A modifier used for the modified mineral filler comprises a combination of an amino-containing coupling agent, a polyarylester, and a rare earth salt. In the polymeric alloy material, the modified mineral filler is obtained by modifying a mineral filler synergistically with the coupling agent, the polyarylester, and the rare earth salt, so that the interaction between minerals and the filler can be enhanced, the dispersity of the mineral filler in the polymer can be improved, and ultraviolet light can be absorbed. Due to the synergy between the modified mineral filler and the interesterification inhibitor, the polymeric alloy material has excellent mechanical properties, weather resistance, and scratch resistance, and the surface gloss is high.
