一种车用低VOC再生聚丙烯复合材料及其制备方法
摘要：
本发明涉及高分子材料技术领域，进一步地说，是涉及一种车用低VOC再生聚丙烯复合材料及其制备方法，所述再生聚丙烯复合材料按重量份数计，由以下组分组成：聚丙烯回料90‑95重量份；非晶态硅酸盐15‑24重量份；密胺树脂型纳米棉颗粒萃取母粒8‑11重量份；增韧剂5‑7重量份；所述密胺树脂型纳米棉颗粒萃取母粒由改性密胺树脂聚合物和萃取液制备而成。本发明采用聚丙烯回料可生产出超低苯、醛含量的聚丙烯汽车内饰件专用料。
摘要（英）：

The invention relates to the technical field of polymer materials, and particularly relates to a vehicular low-VOC recycled polypropylene composite material and a preparation method thereof. The recycled polypropylene composite material comprises the following components in parts by weight: 90-95 parts of recycled polypropylene, 15-24 parts of amorphous silicate, 8-11 parts of melamine resin type nano-cotton granule extractive master batch granules, and 5-7 parts of a flexibilizer, wherein the melamine resin type nano-cotton granule extractive master batch granules are prepared from modified melamine resin polymer and extracting liquid. Special materials for polypropylene automotive upholsteries with ultra-low benzene and aldehyde content can be produced by adopting recycled polypropylene.
