Problems solved by technology

However, in the dry autumn and winter seasons, the surface of plastic materials is easy to accumulate charges and generate static electricity, which brings inconvenience to users and even brings safety hazards
In addition, due to static electricity, the application of plastic products in other parts of the automotive field is also limited.
In addition, with the prolongation of the use time of the car, the plastic car interior parts will gradually age, which not only affects the appearance but also seriously affects the use

preparation example Construction

[0022] The above-mentioned preparation method of antistatic and antiaging plastics for automotive interior parts comprises the following steps:

[0023] 1) prepare dispersant;

[0024] 2) each raw material is taken by weight;

[0025] 3) Place each raw material in a blender and mix and stir evenly;

[0026] 4) Add the homogeneously mixed material in step 3) into the twin-screw extruder, and set the temperature in each area of ​​the twin-screw extruder: 150-180°C for the first zone, 180-220°C for the second zone, and 180-220°C for the third zone 180~220℃, 170~210℃ in the fourth zone; the screw speed is 160~240rpm, after melting and mixing, extrusion and granulation;

[0027] 5) The extruded and granulated particles in step 4) are vacuum-dried at 60-80°C for 6-12 hours, and then transferred to the injection molding machine for injection molding. The mold temperature is 180-210°C, and the molding pressure is 15-28MPa , and finally cooled and demoulded.

Description

technical field [0001] The application relates to the field of composite plastics and its processing, in particular to a plastic for automotive interior parts with antistatic function. Background technique [0002] Nowadays, plastic products have gradually integrated into our lives. At present, car interiors are generally made of plastic materials. However, in the dry autumn and winter seasons, the surface of the plastic material is very easy to accumulate charges and generate static electricity, which brings inconvenience to users and even brings safety hazards. In addition, due to static electricity, the application of plastic products in other parts of the automotive field is also limited. In addition, with the prolongation of the use time of the car, the plastic car interior parts will gradually age, which not only affects the appearance but also seriously affects the use. Therefore, these problems for automotive interior parts must be further studied and solved. Co...
