Embodiment 1～ Embodiment 5

[0027] Weigh the components shown in Table 1 by weight percentage: polypropylene, elastomer, talcum powder, fluoropolymer composition, antioxidant, jasmine flavoring agent. The polypropylene, elastomer, and fluoropolymer compositions were first mixed in a high mixer for 3 minutes, then added with talcum powder, jasmine flavoring agent, and antioxidant, and mixed for another 2 minutes, and the speed of the high mixer was 1500 rpm The premix was melted and extruded by a twin-screw extruder, and vacuum granulated to obtain a flavor-type, self-repairing extrusion-grade polypropylene composite material. The specific data are listed in Table 1.

Embodiment 6

[0029] Weigh the components shown in Table 1 by weight percentage: polypropylene, elastomer, talcum powder, fluoropolymer combination

Embodiment 7

[0031] Take the components shown in Table 1 by weight percentage: polypropylene, elastomer, talcum powder, fluoropolymer composition, antioxidant, sweet-scented osmanthus flavor flavoring agent, preparation method is the same as embodiment 1, performance test data is listed in Table 1.

Abstract

The invention discloses a fragrance self-restoration extrusion stage PP (polypropylene) composite material and a preparation method thereof. The fragrance self-restoration extrusion stage PP composite material is prepared from the following ingredients in percentage by weight: 43 to 96.9 percent of PP, 2 to 20 percent of elastomers, 0 to 30 percent of talcum powder, 1 to 5 percent of fluoropolymer compositions, 0.001 to 0.005 percent of flavouring agents and 0.1 to 2 percent of antioxidants. The fragrance self-restoration extrusion stage polypropylene composite material has the advantages that in the extrusion molding process of the extrusion stage PP, flux is extruded at a high speed, and receives the high-temperature shearing friction effect of an opening mold, so that the degradation of the PP material can be intensified, so that the emission performance of smell and the like of the product becomes worse; few fragrance agents are added, and are non-toxic and harmless, so that no loss is caused on the original mechanical property of the material and the emission performance such as smell, condensing and VOC; the fragrance can shield the unpleasant smell of plastic smell, charring smell and the like of the high polymer material per se and the material high-temperature degradation; the pleasant fragrance is given out, so that the product acceptability is improved.

Description

technical field [0001] The invention relates to a self-repairing extrusion-grade polypropylene composite material, especially a scented, self-repairing extrusion-grade polypropylene composite material; the invention also provides a scented, self-repairing extrusion grade polypropylene composite material; Preparation method of grade polypropylene composite material. Background technique [0002] Polypropylene hydrocarbon materials are the most widely used materials for interior and exterior parts of automobiles, especially polypropylene materials, which have high strength and good comprehensive performance. With the development of the automobile industry, the amount of polypropylene used in automobiles has grown rapidly in the past few years. Especially in recent years, major OEMs have increasingly stringent requirements on the emission performance of automotive interior materials, among which the smell is particularly prominent, and the smell is the most intuitive and the mo...
