Abstract

The invention relates to the technical field of modified materials and discloses a preparation method of a polypropylene composition with low gloss, scratch resistance and high impact resistance. The polypropylene composition is prepared from the following raw materials in parts by mass: 45 to 60 parts of polypropylene, 10 to 25 parts of polyolefin elastomer serving as a impact-resisting modifier, 15 to 25 parts of talcum powder, 5 to10 parts of a low-gloss agent, 1.0 to 3.0 parts of a scratch-resisting agent, 0.5 to 2.0 parts of a scratch-resisting synergic agent and 0.1 to 0.5 part of an antioxidant. The polypropylene composition has the characteristics that firstly, good appearance, low glossiness and no tacky phenomenon of surface after light aging; secondly, excellent scratch resistance under the conditions of high impact and low hardness; thirdly, excellent mechanical property, rigid-tough balance and good formability.

Description

technical field [0001] The invention relates to the technical field of modified materials, in particular to a low-gloss, scratch-resistant, high-impact polypropylene composition and a preparation method thereof. Background technique [0002] Polypropylene (PP) material has been widely used in various assembly systems of automobiles due to its good comprehensive performance. Most of the automotive exterior and interior parts are injection molded using polypropylene composite materials. Exterior parts such as bumpers, thresholds, skirts, etc., automotive interior parts such as instrument panels, pillars, glove boxes, door panels, etc. In addition to good mechanical properties, processing properties, and weather resistance, automotive interior materials also need Good appearance, by reducing the interior gloss and improving scratch resistance, not only can meet the requirements of good appearance, but also can achieve the effect of environmental protection and energy saving th...
