Title:
WALL-THINNING FLAME-RETARDANT POLYCARBONATE/POLYETHYLENE TEREPHTHALATE ALLOY AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2021/052088
Kind Code:
A1
Abstract:
Provided in the present invention is a wall-thinning flame-retardant polycarbonate/polyethylene terephthalate alloy, comprising the following components in terms of parts by weight: polycarbonate 50-80 parts; polyethylene terephthalate 10-50 parts, and a flame retardant 0.1-15 parts. The weight-average molecular mass of the polycarbonate is greater than 24,000, the polydispersity index (PDI) is less than 2.7, and the melt flow index stability evaluation (MI%) is < 10%. The present invention controls the weight-average molecular mass of the polycarbonate, the polydispersity index (PDI), and the melt flow index stability evaluation (MI%), compared with a regular polycarbonate, the polycarbonate having the described parameters is provided with improved compatibility with polyethylene terephthalate, the alloy produced by such preparation provides improved wall-thinning and flame-retarding effects.
