Embodiment Construction

[0017] The technical solution of the present invention will be further elaborated below through specific examples.

[0018] A kind of preparation method of polypropylene high-filling toughening masterbatch described in the present invention, comprises the following steps:

[0019] 1. After ordinary calcite is processed into superfine heavy calcium carbonate powder, it is activated and modified by a high-pressure air flow machine to obtain a superfine modified powder.

[0020] 2. Ingredients: 150 kg of superfine modified powder, 14-17 kg of polypropylene resin, 3.15-3.85 kg of PP wax, 2.25-2.75 kg of PE wax, 1.8-2.2 kg of monoglyceride, 1.8-2.2 kg of aluminate Kilograms and 4 to 8 kilograms of calcium stearate are used for batching.

[0021] 3. Mixing: The above materials are fully mixed at a high temperature of 140-180°C.

[0022] 4. Pelletizing: After the uniformly mixed material is cooled, put it into the extruder again, and the temperature is controlled between 180 ~ 240 ...

Abstract

The invention relates to a polypropylene high-filled toughening masterbatch and a preparation method thereof, and the preparation method comprises the following steps: taking ultra-fine active heavy calcium carbonate as a base, adding calcium carbonate powder, polypropylene resin, auxiliaries and a dispersing agent, carrying out activation and modification by a high-pressure gas flow machine, mixing, and carrying out extrusion molding for preparing the polypropylene high-filled toughening masterbatch. The filled masterbatch not only has large filling amount, but also still keeps the original excellent performances of plastic after filling, and improves the toughness, the rigidity and the smoothness of a product.

Description

technical field [0001] The invention relates to a high-filling and toughening master batch of polypropylene and a manufacturing method thereof. Background technique [0002] At present, only a few countries such as the United States, Germany, Japan, and South Korea have the technology and equipment to produce high-performance powders, and have strong advantages. At present, my country's powder chemical industry has always relied on imports for its demand for high-quality non-metallic mineral products. At present, there is no professional system for the research and development of powder activation modification technology in China, and there is no specialized production base and market. Some domestic powder companies, their products are primary raw materials with low grades, resulting in a great waste of various resources. And can not change the current backward status quo. Contents of the invention [0003] The object of the present invention is to provide a polypropylen...
