Abstract

The invention discloses a flame-retardant PC / ABS composite material with high hydrolysis resistance and a preparation method thereof. The composite material comprises PC resin, ABS resin, a fire retardant, a flexibilizer, a chain extender and other auxiliaries. According to the composite material, the flexibilizer with specific number-average particle size and specific molecular structure and the chain extender with high epoxide equivalent are selected, the hydrolysis resistance of the flame-retardant PC / ABS composite material can be improved by optimizing the raw materials, and the flame-retardant PC / ABS composite material can have relatively ideal flame retardance and mechanical property after being subjected to long-time high temperature and high humidity treatment and is particularly suitable for the occasions with relatively high requirements for the use environments.

Description

technical field

[0001] The invention relates to a PC / ABS composite material and a preparation method thereof, in particular to a highly hydrolysis-resistant flame-retardant PC / ABS composite material and a preparation method thereof, belonging to the technical field of polymer composite materials and processing thereof. Background technique

[0002] PC / ABS composite material is an important engineering plastic, which not only improves the heat resistance and tensile strength of ABS, but also reduces the melt viscosity of PC and improves the processing performance of the composite material. However, since the PC resin itself contains carbonate bonds that are sensitive to water, the presence of a small amount of water will cause the molecular chain to break and lead to a decrease in the mechanical properties of PC; in addition, in the process of synthesizing ABS or toughening agent, similar catalyst residues It will also aggravate the degradation of PC; the above reasons will l...
