Abstract

The invention discloses a composite material for recycling waste vehicle nylon products and a preparation method thereof. The composite material comprises the following components by weight percent: 0-85 percent of PA original material, 10-95 percent of recovered PA material, 5-40 percent of glass fiber, 0-2 percent of nucleating agent, 0-0.5 percent of chain extender, 0-5 percent of chain breaking agent, 0-30 percent of toughening agent, 0-2 percent of heat stabilizer and 0-1 percent of processing aid. The method comprises the following steps of: mixing the PA original material, the PA material, the nucleating agent, the chain extender, the chain breaking agent, the toughening agent, the heat stabilizer and the processing aid at high speed to obtain a mixed material; adding the mixed material from a main feeding port of a twin-screw extruder, adding the glass fiber from a second feeding port of the twin-screw extruder, and mixing the mixed material and the glass fiber in the twin-screw extruder; and extruding and pelletizing the mixture to obtain the composite material. The composite material for recycling nylon products is simple and convenient, is easy to control and can protect environment.

Description

technical field [0001] The invention relates to the technical field of chemical materials, in particular to a composite material for recycling waste automobile nylon parts and a preparation method thereof. Background technique [0002] Nylon (PA) is currently one of the most widely used engineering plastics in engineering plastics. Each car uses about 15 kg of PA materials, which are widely used in engine cooling fans and windshields, radiator water tanks, headlight lamp rings, and power steering tanks. , engine cover, rocker cover, intake manifold, shift module, brake release handle, mirror assembly and connector, etc., the above materials are all made of PA66 or PA6 with additives such as glass fiber and heat stabilizer. obtained composite material. As the number of scrapped cars increases year by year (the National Development and Reform Commission announced that the number of scrapped cars in my country in 2009 was about 2.7 million), the reasonable and efficient recycl...
