Embodiment 1-20 and comparative example 1-2

[0058] Preparation of polypropylene carrier:

[0059] According to the ratios in Table 1 and Table 2, the polypropylene and the porous adsorbent are fully mixed in a high-speed mixer, melt blended, extruded and granulated in an extruder to obtain a foamed polypropylene precursor; using a physical foaming agent The foamed polypropylene precursor was foamed to obtain a polypropylene carrier; the performance test results of the polypropylene carrier are shown in Table 4.

[0060] Preparation of VOC extractant for modified polypropylene:

[0061] According to the proportions in Table 1 and Table 2, the prepared polypropylene carrier and non-fluorine non-ionic surfactant solution are passed through a high-speed mixer according to the proportion, and stirred at a speed of 1000 rpm for 3-5 minutes to obtain a modified polypropylene VOC extractant for propylene.

Embodiment 21-40 and comparative example 3-4

[0063] Preparation of environmentally friendly modified polypropylene composite materials:

[0064] The VOC extraction agent for modified polypropylene prepared in the order of Table 1 and Table 2 is used to further prepare environment-friendly modified polypropylene composite materials (Example 1-20 corresponds to Example 21-40 in sequence, and Comparative Example 1-2 corresponds to Example 21-40 in sequence) Coping ratio 3-4): Put 20 parts by weight of talcum powder into the extruder from the side feeding port, 78 parts by weight of polypropylene and 2 parts by weight of VOC extraction agent are mixed evenly in the high-speed mixer, and then put into the double feeder from the main feeding port Melt blending in a screw extruder. The degree of vacuum is controlled, extruded and granulated to obtain an environmentally friendly modified polypropylene composite material. The odor performance test results of the environmentally friendly modified polypropylene composite material ...

Abstract

A VOC extractant used for modified polypropylene, and a preparing method and applications thereof are disclosed. The VOC extractant includes 11-50 wt% of a polypropylene carrier and 50-89 wt% of a non-fluorine type nonionic surfactant solution. The non-fluorine type nonionic surfactant solution includes 0.1-2.5 wt% of a non-fluorine type nonionic surfactant and 97.5-99.9 wt% of a solvent. The VOCextractant has characteristics of capabilities of being safe, environmentally friendly, cheap, and the like, and has an extremely high removal rate for VOCs in a modified polypropylene material. In aprocess of preparing the environmentally friendly modified polypropylene material, the VOC extractant is mixed with polypropylene and an auxiliary agent, the mixture is fully stirred by an efficient material mixer, and then the mixture is subjected to twin-screw extrusion and granulation to obtain the environmentally friendly modified polypropylene material.

Description

technical field [0001] The invention relates to the technical field of composite polymer materials and processing thereof, in particular to a VOC extractant for modified polypropylene and its preparation method and application. Background technique [0002] Polypropylene is a kind of thermoplastic resin prepared by polymerizing propylene, which has the advantages of heat resistance and corrosion resistance, and is the lightest general-purpose plastic. Modified polypropylene has the characteristics of high crystallinity, excellent mechanical properties, easy processing, good appearance, and low price. It is widely used in automotive interior parts, such as instrument panels, sub-dashboards, door panels, map bags, glove boxes and Columns, etc., its consumption accounts for about 50% of the polymer materials of the vehicle. [0003] After extrusion granulation and molding processing, polypropylene resin will release amines, phenols, mercaptans, peroxides, benzene, aldehydes, k...
