A high gloss polypropylene material

Abstract

The invention provides a high-gloss polypropylene material which is characterized by being obtained by physical modification and comprising the following components: 100 parts of polypropylene, 20-35 parts of barium sulfate, 5-20 parts of POE (polyolefin elastomer), 0.1-0.4 part of nucleating agent, 0.1-0.2 part of antioxidant 1010, 0.1-0.2 part of antioxidant 168 and 0.1-0.3 part of lubricant. The modified PP aggregates have low forming shrinkage, high gloss and high toughness and have the advantage of elegant and attractive appearance of acrylonitrile butadiene styrene. Meanwhile, the cost is greatly reduced.

Description

technical field [0001] The invention relates to the field of polypropylene (PP) modification, in particular to a high-gloss polypropylene material that improves the gloss and toughness of PP and reduces the shrinkage of PP through modification of PP. Background technique [0002] The adjustment frame of the infusion set is generally made of ABS or PP injection molding. High-end and precision infusion sets use ABS as the adjustment frame, because the adjustment frame of the ABS injection molding is generous and beautiful, the flow rate is adjusted accurately, and the gloss is good, but the cost is relatively expensive; and Ordinary PP injection molding adjustment frame has low gloss and poor toughness. [0003] Polypropylene is currently the second most used general-purpose plastic. It has excellent comprehensive properties, stable chemical properties, good molding and processing performance, and low price. These advantages make it possible to replace ABS, but at the same tim...

[0002] The adjustment frame of the infusion set is generally made of ABS or PP injection molding. High-end and precision infusion sets use ABS as the adjustment frame, because the adjustment frame of the ABS injection molding is generous and beautiful, the flow rate is adjusted accurately, and the gloss is good, but the cost is relatively expensive; and Ordinary PP injection molding adjustment frame, low gloss, poor toughness

[0003] Polypropylene is currently the second most used general-purpose plastic. It has excellent comprehensive properties, stable chemical properties, good molding and processing performance, and low price. These advantages make it possible to replace ABS, but at the same time PP also has strength. Low, high low temperature brittleness, large shrinkage, etc.
