Problems solved by technology

The disadvantage of this invention is that the 30-50% glass fiber reinforced PPS used is melted and mixed in a twin-screw extruder. Due to the shearing effect of the twin-screw, the length of the glass fiber is relatively short, only 0.3-0.5mm, which is not suitable for PPS materials. The toughening effect of the impeller is not ideal, resulting in the rigidity of the impeller to be improved

Abstract

The invention relates to the field of polymer materials, and relates to a continuous long fiber reinforced PPS composite material and a preparation method thereof. The composite material comprises the following components by weight: 450-650 parts of polyphenylene sulfide, 300-500 parts of a continuous fiber reinforced agent, 5-10 parts of a coupling agent, 10-30 parts of an antioxidant and 10-20 parts of a lubricant. Compared with the prior art, an engine cooling water pump impeller made from the material through injection moulding has characteristics of light weight, good dimensional stability, stable working dynamic balancing performance, strong resistance to chemical corrosion and high strength; an automobile water pump using the continuous long fiber reinforce PPS impeller has smooth working performance, high efficiency and long service life, and can work normally at the temperature of -40 DEG C to -140 DEG C.

Description

technical field [0001] The invention relates to the field of polymer materials, and relates to a continuous long fiber reinforced PPS composite material and a preparation method thereof. Background technique [0002] The automobile water pump is an important part of the engine cooling system. Its function is to pump the coolant, so that the coolant flows quickly in the cooling water channel of the engine, so as to take away the heat generated when the engine is working, and maintain the normal operating temperature of the engine. The water pump used in the automobile engine is a centrifugal water pump, which is composed of a casing, an impeller, a bearing, a pump shaft, a water seal, and a transmission pulley. The impeller is an important part of the water pump. At present, the materials used for the impeller of the automobile engine cooling water pump are mainly cast iron, steel plate or aluminum alloy, each with its own characteristics and shortcomings. Cast iron impeller...
