Abstract

The invention discloses low-odor mineral reinforced polypropylene composite material and a preparation method thereof. The material is prepared from the following components in percentage by weight: 54-88.5% of polypropylene, 10-40% of filling minerals, 0.5-5% of an odor removing liquid, 0.2-1% of an antioxidant and 0.2-1% of a lubricant. The preparation method comprises the following steps: mixing the raw materials except the odor removing liquid in a high-speed mixer and discharging; putting the mixed raw materials into a main feeding opening of a twin-screw extruder; metering and inputting the odor removing liquid from a side feeding opening by virtue of a centrifugal pump; vacuumizing; carrying out melt extrusion and prilling by virtue of the twin-screw extruder to prepare the low-odor mineral reinforced polypropylene composite material. Compared with the prior art, the low-odor mineral reinforced polypropylene composite material prepared by the reparation method provided by the invention is excellent in mechanical property, low in VOC and environment-friendly and can be widely used in the fields of automobiles, household appliances, sports articles and the like.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a low-odor mineral reinforced polypropylene composite material and a preparation method thereof. Background technique [0002] Mineral reinforced polypropylene is widely used in automobiles, home appliances and other industries due to its excellent mechanical properties, good dimensional stability, high heat resistance, and low cost. However, mineral reinforced polypropylene materials will release some toxic and harmful gases, which not only cause harm to the human body, but also affect the quality of the product. Moreover, with the enhancement of people's awareness of environmental protection and health, the preparation of low-odor mineral-reinforced polypropylene has become a development trend of mineral-reinforced polypropylene. [0003] The odor of mineral-enhanced polypropylene is mainly composed of the following aspects: 1) The odor of the raw material itself, including th...
