Abstract

The invention discloses a halogen-free flame-retardant glassfiber reinforced polycarbonate / polybutylene terephthalate (PC / PBT) alloy material and a preparation method thereof. The halogen-free flame-retardant glassfiber reinforced PC / PBT alloy material consists of the following components in percentage by weight: 53 to 66.6 percent of PC resin, 10 to 20 percent of PBT resin, 1 to 2 percent of compatilizer, 3 to 5 percent of toughening agent, 1 to 5 percent of halogen-free flame retardant, 10 to 20 percent of glass fiber, 0.3 to 0.8 percent of coupling agent, 0.6 to 1 percent of lubricant and 0.2 to 0.5 percent of antioxidant. The halogen-free flame-retardant glassfiber reinforced PC / PBT alloy material of the invention has the advantages of high melt fluidity, bright and clean surface of product, and good comprehensive performance and can be used for manufacturing liquid crystal inner frames, television modules and some external products having high surface requirements.

Description

[technical field] [0001] The invention relates to the technical field of polymer materials, in particular to a halogen-free flame-retardant glass fiber reinforced PC / PBT alloy material and a preparation method thereof.
