preparation example Construction

[0026] The embodiment of the present invention further provides a method for preparing the above-mentioned polypropylene composite material, which includes the following steps:

[0027] Step S01, provide raw materials:

[0028] Weigh the polypropylene, acrylonitrile-butadiene-styrene copolymer, barium sulfate masterbatch, compatibilizer, dispersant and antioxidant according to the formula;

[0029] Step S02, mixing the raw materials:

[0030] Mix the polypropylene, acrylonitrile-butadiene-styrene copolymer, barium sulfate masterbatch, compatibilizer, dispersant and antioxidant to obtain a mixture;

[0031] Step S03, melt extrusion processing:

[0032] The mixture is melted and extruded at a temperature of 170-230°C to obtain a polypropylene composite material.

[0033] In step S01, the polypropylene, the acrylonitrile-butadiene-styrene copolymer, the barium sulfate masterbatch, the compatibilizer, the dispersant and the antioxidant are the same as the foregoing, and the description is not...

Embodiment 1

[0042] The preparation method of the polypropylene composite material of the embodiment of the present invention includes the following steps:

[0043] Provide the following components by weight percentage:

[0044] PP resin 40%, ABS 44.5%, compatibilizer 5%, barium sulfate 10%, dispersant 0.3%, antioxidant 0.2%;

Abstract

The present invention belongs to the field of engineering plastics, and provides a polypropylene composite material, a preparation method and applications thereof. The polypropylene composite material comprises polypropylene, an acrylonitrile-butadiene-styrene copolymer, barium sulfate master batch, a compatibilizer, a dispersing agent and an antioxidant. According to the polypropylene composite material, ABS, barium sulfate master batch and a dispersing agent are mutually matched, such that gloss of the polypropylene composite material is substantially improved, and the polypropylene composite material having an appearance similar to ABS is achieved.

Description

Technical field [0001] The invention belongs to the technical field of engineering plastics, and particularly relates to a polypropylene composite material, a preparation method and application thereof. Background technique [0002] Polypropylene (PP) is one of the five general-purpose plastics. Its output and consumption are second only to polyethylene (PE) and polyvinyl chloride (PVC). It is the third largest plastic variety and a large general-purpose resin product closely related to our daily lives. . Currently, polypropylene is the fastest growing general-purpose plastic in the world. Polypropylene is the most widely used in general-purpose plastics. There are various ways to modify it and the products are more comprehensive. At present, the application of PP material is mainly limited by its larger shrinkage rate, which is often 1.4-2.2%, showing poor dimensional stability. Moreover, the glossiness of polypropylene is also a major factor affecting its application. Summa...
