Problems solved by technology

[0002] Polypropylene (PP) has a wide range of applications, especially in the field of automobile industrialization. However, due to the high insulation of polypropylene, it is easy to accumulate static electricity during production, transportation and use, which will damage the circuit boards and electronic components in the car. The device is harmful; and it is easy to absorb a large amount of dust during use, causing the PM2.5 in the car to exceed the standard

preparation example Construction

[0036] A general method for preparing a modified polypropylene material with improved antistatic properties, including:

[0037] 1) Drying the PP plastic particles, the drying method is as follows: treat the PP plastic particles at 80°C for 2 hours;

[0038] 2) Add the dried PP plastic particles, POE, filler talc powder and antistatic agent into the high-speed mixer, and mix at high speed for a period of time;

[0039] 3) The mixture prepared in step 2) is extruded and blended by a twin-screw extruder at 195-220°C, the die position is loaded with 10V voltage, the screw speed is 45rpm / min, after extrusion, stretching, cooling, Granulating to obtain a modified polypropylene material with improved antistatic properties.

Embodiment 1

[0041] Observe the effect of different antistatic agents on resistivity. The steps are:

[0042] 1) Dry the PP plastic particles (80°C, 2h);

[0043] 2) Add PP plastic particles, POE, talc powder and antistatic agent composite nano-titanium dioxide into a high-speed (mixing speed of 300 rpm) mixer, and mix at high speed for 28 minutes;

Abstract

The invention discloses a modified polypropylene material for improving the antistatic property. The modified polypropylene material is prepared from, by weight, 75-100 parts of polypropylene plastic particles, 10-15 parts of POE, 10-20 parts of filler and 0.5-1 part of an antistatic agent. The antistatic agent is prepared from nano-titanium oxide, ethylene oxide and trialkyl ammonium salt at the mass ratio of (40-50):(30-40):(10-30). According to the modified polypropylene material for improving the antistatic property, the surface conductivity of the product is improved by adding the proper antistatic agent, and thus static is reduced as much as possible.
