Abstract

The invention belongs to the technical field of polymer materials, and relates to a fiber-reinforced polyphenylene sulfide / polyamide alloy material and a preparation method thereof. The material comprises the following components by weight: 25-56 parts of polyphenylene sulfide, 10-35 parts of polyamide 66, 15-25 parts of carbon fibers, 15-25 parts of glass fibers, 0.5-0.7 parts of an antioxidant, 0.7-1.2 parts of a lubricant and 1-1.5 parts of a coupling agent. In the PPS / PA66 alloy material provided by the invention, the carbon fibers are used for reinforcing conductivity of the material, without reducing the mechanical properties of the material. The material has excellent mechanical properties as well as antistatic properties. The cost of the material is relatively low due to the compound of the fibers and the addition of PA66.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and relates to a fiber-reinforced polyphenylene sulfide / polyamide alloy material and a preparation method thereof. Background technique [0002] Polyphenylene sulfide is abbreviated as PPS in English. It is a special engineering plastic with excellent comprehensive performance. Its consumption ranks sixth among engineering plastics, only after the five general-purpose engineering plastics. PPS resin has the advantages of excellent heat resistance, chemical resistance, electrical insulation, heat and humidity resistance, etc. After being reinforced with glass fiber, the material also has excellent mechanical properties. However, PPS has low impact strength, poor toughness, high melt viscosity, poor processing performance, and relatively high cost. These shortcomings limit the application of PPS in the field of mid-end products. Polyamide (PA) 66 is one of the five major engineering plas...
