Embodiment 1

[0041] A kind of anti-alcoholysis heat stable PPA composite material, comprising by weight:

[0042]

[0043] Put the above-mentioned materials except chopped glass fiber and epoxy-based prehydrolysis coupling agent into a high-speed mixer and mix evenly (mixing for 3 minutes, high-speed mixer speed 500RPM), and then put the mixed material into the extruder The main discharge barrel of the machine is granulated through the extruder. During the extrusion process, 30 parts of chopped fibers are added by side feeding, and 0.5 parts of epoxy-based pre-hydrolysis coupling agent is added through a micro pump to keep the vacuum open. The temperature of each temperature zone of the extruder is: zone 1 150°C, zone 2 320°C, zone 3 320°C, zone 4 320°C, zone 5 310°C, zone 6 300°C, zone 7 290°C, zone 8 290°C, The ninth zone is 290°C, the tenth zone is 290°C, the eleventh zone is 300°C, the head is 310°C, and the speed of the extruder is 400RPM.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to an alcohololysis-resistant heat-stable PPA composite material and a preparation method thereof. Background technique [0002] Long carbon chain nylons such as PA66 and PA6 have the characteristics of oil resistance, organic solvent resistance and excellent mechanical properties, and are widely used in electronic appliances, automobiles, home appliances, office equipment and other fields. However, long carbon chain nylon is easy to absorb water, has poor hydrolysis resistance, poor thermal stability, and poor dimensional stability, which limit its application in high temperature, high humidity or water environments. On the other hand, metal materials have the characteristics of high strength, corrosion resistance, dimensional stability, and creep resistance, and are widely used in the field of machinery manufacturing. However, with the continuous advancement of industri...
