Embodiment 1
[0039] Prepare according to the following formula:
[0040] (a) 70 parts by mass of polypropylene
[0041] (b) 30 parts by mass of mineral filler (wollastonite)
[0042] (c) 3 parts by mass of odor adsorbent
[0043] (d) 0.1 parts by mass of additives
[0044] Wherein, the odor adsorbent includes: bentonite, porous silica and activated alumina, according to the mass ratio, bentonite: porous silica: activated alumina=1: 1: 1;
[0045]First mix polypropylene and mineral filler at 1200 rpm for 5 minutes, then add odor adsorbent, stir at 1500 rpm for 10 minutes, and finally add additives, at 1200 rpm Stir for 5 minutes at a rotational speed to obtain a premix. The premixed material is fed into a twin-screw extruder, extruded and granulated to obtain a low-emission modified polypropylene composite material, which can be used for automotive interior parts.
[0046] After testing, the properties of the prepared polypropylene composite material are as follows:
