Problems solved by technology

Polypropylene material is non-toxic and tasteless, and has no effect on the human body. Its quality and easy molding characteristics have been studied by many countries to replace PS materials for food packaging. However, compared with PS, polypropylene has a small elastic modulus and poor fracture performance.

Abstract

The invention discloses a modified polypropylene master batch. The modified polypropylene master batch is prepared from, by weight, 60-65% of an inorganic matter mixture, 16-20% of polypropylene, 5-8% of special resin A, 4-6% of special resin B, 2-4% of PE wax, 2-4% of a dispersing agent and 0.5-0.6% of a stiffening agent. The invention further discloses a preparing method of the modified polypropylene master batch.

Description

technical field [0001] The invention belongs to the field of modified materials, and in particular relates to a modified polypropylene masterbatch and a preparation method thereof. Background technique [0002] Polystyrene, abbreviated as PS, is widely used in the production of yogurt cups, especially eight cups, because of its high modulus, easy to break, and easy to shape. , harmful to the human body. From 2023, the European Union will ban the use of PS materials for food packaging. Polypropylene material is non-toxic and tasteless, and has no effect on the human body. Its quality and easy molding characteristics have been studied by many countries to replace PS materials for food packaging. However, compared with PS, polypropylene has a small elastic modulus and poor fracture performance. . Therefore, it is now necessary to find a non-toxic and harmless material with good breakability for the production of yogurt cups. Contents of the invention [0003] The technica...
