Abstract

The invention discloses a preparation method of POM plastic particles used for an automobile fuel tank, which comprises the following step: adding the components according to mass part in a feed mixer, uniformly mixing to obtain a main material; then adding an auxiliary agent, uniformly mixing to obtain a mixture; adding in a twin-screw extruder, wherein the screw speed is 400-450r/min, after uniformly mixing, performing fusion extrusion to obtain a granular mixture under 260-300 DEG C; and cooling the granular mixture and granulating to obtain the product. The preparation method has the advantages of simple production technology, convenient operation and low cost. The fuel tank product prepared by the plastic particles has the advantages of uniform wall thickness, good intensity, impact resistance and excellent falling performance, and can be used for long-term application under outdoor scurviness environment (severe cold, intense heat of summer and long-term bumpiness shock).
