Abstract

The invention belongs to the technical field of high-molecular materials, and relates to a polyphenylene sulfide / nylon alloy material and a preparation method thereof. The material is prepared from the following compositions in parts by weight: 20-30 parts of polyphenylene sulfide, 40-50 parts of glass fiber, 20-40 parts of nylon, 0.3-0.8 part of a lubricant and 0.2-0.4 part of an anti-oxidant. The material provided by the invention has the advantages of polyphenylene sulfide and nylon by compounding polyphenylene sulfide and nylon, and has relatively high strength and flame retardance and high hardness by glass fiber reinforcement. The material is relatively widely applied to structure members of industries such as electric appliances, automobile production and the like, and the application scope of the material is relatively expanded.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and relates to a polyphenylene sulfide / nylon alloy material and a preparation method thereof.
