Problems solved by technology

[0005] However, the above-mentioned patents CN 105440438B and CN106752633A disclose a modification scheme for improving polarity, but they have an impact on the impact of the material; the complexity of the process of the patent CN107641256A affects the processing efficiency, so it is still necessary to develop a method that does not affect the impact in this area. The method is simple, and can satisfy high-pressure water flushing and is easy to spray polypropylene composition material and preparation method

Abstract

The invention discloses an easy-sprayed polypropylene composition and a preparation method therefor. The composition comprises the following ingredients in parts by weight: 33-77.6 parts of polypropylene resin, 10-15 parts of POE, 10-30 parts of mineral filler, 1-5 parts of grafts, 1-15 parts of cycloolefin copolymer, 0.2-1 part of stabilizer and 0.2-1 part of colorant. According to the easy-sprayed polypropylene composition and the preparation method therefor, by using mutual coordination of the grafts and the cycloolefin copolymer, the surface tension of a material is improved, and the adhesive power of paint is improved; and the adhesive power performance of the paint during high-pressure water flush experimentation is improved.

Description

technical field [0001] The invention belongs to the technical field of polymer material modification, and in particular relates to an easy-to-spray polypropylene composition and a preparation method thereof. Background technique [0002] Polypropylene (PP), as one of the five general-purpose plastics, has become the most used thermoplastic resin in automotive plastics. The synthesis method of polypropylene is simple, the source of raw materials is abundant, the density is low, and it has excellent physical and mechanical properties, processing properties and chemical resistance. At the same time, the modified polypropylene materials obtained through various modification processing methods can meet the different requirements of various automobile parts, and its excellent cost performance makes various toughened, filled and reinforced polypropylene materials widely used in the automobile industry. Applications, especially under the vigorous development of new energy vehicles,...
