As shown in table 1, weigh polypropylene and raise sub-petrochemical industry SP179,44 weight parts; Polypropylene oil of SPC M700R, 25 weight parts; Polyethylene Yanshan Petrochemical LDPE100AC, 5 weight parts; Toughner LG company POELC175,5 weight parts; Talcum powder 1250 order, 20 weight parts; Antioxidant 1010,0.2 weight part; Anti-oxidant DLTP, 0.2 weight part; Oxidation inhibitor DSTP, 0.2 weight part; Lubricant stearic acid calcium, 0.4 weight part.By each component stirring at low speed more than 10 minutes in agitator kettle, after mixing, put into forcing machine hopper, by twin screw extruder melt blending, extrude material strip cooling, air-dry, pelletizing, all mixed, packaging.
Processing parameter, batten preparation condition and testing method are with embodiment 1.
Table 2 is obtained polypropylene material the performance test results, and the sporadic requirement of general polypropylene automotive interior part is: TVOC≤50 μ gC/g, condensable components≤2mg/g.The data of embodiment 1-6 and comparative example 1-4 as can be seen from table, the mechanical property of each example is more or less the same, but comparison in difference is large in VOC and cryolac number.
Comparative example 1-3, introduces polyethylene or toughner has no significant effect the sporadic of material.
Comparative example 1 and comparative example 1-2, polypropylene base-material sporadic on material modified sporadic impact comparatively large (TVOC of polypropylene 1215C, K8025 is much larger than SP179 and M700R).
Comparative example 1 and comparative example 2, along with the increase of compatilizer consumption, TVOC and the condensable components content of material all increase, and increase the sporadic of material.
Comparative example 1 and comparative example 3, along with the introducing of compatilizer, TVOC and the condensable components content of material all increase, and increase the sporadic of material.
Comparative example 1,4 and comparative example 4, can significantly reduce the adding of deodovization agent sporadic.
Comprehensive Correlation embodiment 1-6 and comparative example 1-4, chooses the polypropylene matrix of low TVOC, adds a small amount of deodovization agent, and the polypropylene material prepared while guarantee mechanical property, can have low sporadic feature, can be applied to automotive upholstery.
The polypropylene material test result that table 2 is obtained
