| titleOfInvention | Low-odor polypropylene composite material and preparation method thereof |
| abstract | The invention belongs to the technical field of modification of polymer composite materials, and particularly relates to a low-odor polypropylene composite material and a preparation method thereof. The polypropylene composite material takes block copolymerization polypropylene as a basic component, talcum powder master batches are added to improve the dispersibility of the material, high-density polyethylene with high melt mass flow rate and ethylene-butylene copolymer are taken as toughening agents, deodorant master batches formed by crosslinked sodium polyacrylate adsorbing alcohol water solution adsorb organic micromolecules, and polyamide-amine dendritic macromolecules are taken as lubricants to improve the processing fluidity and the glossiness of products. In addition, the polypropylene composite material adopts a double-screw extruder with super-large length-diameter ratio, high rotating speed and large torque to carry out melt mixing so as to improve the stability of the material; and the removal rate of the micromolecules is improved by adopting double vacuum ports for vacuumizing treatment, so that the obtained composite material has the advantages of easiness in processing, low volatility, low odor and excellent physical and mechanical properties, and the requirement of automotive upholstery on the material can be completely met. |
