Embodiment 1

[0017] Weigh PPS58% according to mass ratio, ethylene-maleic anhydride-glycidyl methacrylate terpolymer 5%, continuous long glass fiber 35%, antioxidant 1%, lubricant 1%, except long glass fiber Other materials are mixed in a high-speed mixer for 6 minutes at a mixing speed of 50r / min, and added from the hopper of the twin-screw extruder, and the long glass fiber is drawn and added at the first exhaust port, and then injection molded after melt extrusion and granulation. Tested according to ASTM standards.

Embodiment 2

[0019] Weigh PPS58% according to mass ratio, ethylene-maleic anhydride-glycidyl methacrylate terpolymer 5%, continuous long carbon fiber 35%, antioxidant 1%, lubricant 1%, other materials except long carbon fiber Mix in a high-speed mixer for 6 minutes at a mixing speed of 50r / min, add it from the hopper of the twin-screw extruder, add the long glass fiber at the first exhaust port after being drawn, and inject it after melt extrusion and granulation, according to ASTM standard test.

Embodiment 3

[0021] Weigh PPS58% by mass ratio, ethylene-maleic anhydride-glycidyl methacrylate terpolymer 5%, continuous long fiber 35% (continuous long carbon fiber 10%, continuous long glass fiber 25%), antioxidant 1%, lubricant 1%, other materials except long fibers were mixed in a high-speed mixer for 6 minutes at a mixing speed of 50r / min, added from the hopper of the twin-screw extruder, and the long fibers were added at the first exhaust port after traction , injection molding after melt extrusion granulation, tested according to ASTM standard.

[0022] The product performance is shown in Table 1.

Abstract

The invention discloses a continuous-long-fiber-reinforced / toughened PPS (polyphenylene sulfide) composite material which is composed of the following components in parts by weight: 45-60 parts of polyphenyl thioether, 2-10 parts of elastomer, 15-40 parts of continuous long fiber and 0.1-5 parts of processing aid. The invention also discloses a preparation method of the continuous-long-fiber-reinforced / toughened PPS composite material. Continuous long fibers are added at the first air outlet of an extruder under the action of a tractor. The PPS composite product has high surface quality; and the production technique is stable and simple to operate, and obviously improves the mechanical properties and thermal properties.

Description

technical field [0001] The invention relates to a continuous long fiber reinforced and toughened PPS composite material and a preparation method thereof, belonging to the field of composite materials. Background technique [0002] Polyphenylene sulfide (PPS) is a special engineering plastic with excellent comprehensive performance. It is the most cost-effective kind of special engineering plastics. It is one of the six general-purpose engineering plastics and one of the eight aerospace materials. It has excellent high temperature resistance, chemical corrosion resistance, flame retardant and wear resistance, excellent dimensional stability and excellent electrical properties, etc., but there are a large number of benzene rings in the main chain of PPS, and the crystallinity is high, so that its elongation at break is low , poor toughness and impact resistance, which limits its application to some extent. [0003] Most of the existing patents use PPS and other resin blendin...
