The invention relates to the field of automotive interiors, in particular to a low-VOC modified polypropylene material and a preparation method of an automotive carpet. The material is prepared from 20 to 30 parts of maleic anhydride grafted polypropylene, 5 to 8 parts of ethylene-alkyl acrylate, 3 to 6 parts of di-tert-butyl peroxide, 0.1 to 0.4 part of calcium carbonate, 0.2 to 0.4 part of antioxidant and 0.3 to 0.5 part of light stabilizer, a preparation method of the low-VOC modified polypropylene material comprises the following steps: weighing the maleic anhydride grafted polypropylene, the ethylene-alkyl acrylate, the calcium carbonate, the antioxidant and the light stabilizer, uniformly mixing, placing in an environment of 45-65 DEG C, preserving heat for 1-2 hours, then adding the di-tert-butyl peroxide in parts by weight, and stirring for 2-3 hours at the speed of 200-240 r/min to prepare the low-VOC modified polypropylene material. The material is flatly laid on a base material, and cooling, stamping and cutting are carried out. Through synergistic cooperation of the maleic anhydride grafted polypropylene, the ethylene-alkyl acrylate, the di-tert-butyl peroxide and other components, the technical problem of excessive VOC release is solved from the source of the raw materials.
本申请涉及汽车内饰的领域,更具体地说,它涉及一种低VOC的改性聚丙烯材料及汽车地毯的制备方法。该材料包括马来酸酐接枝聚丙烯20~30份、乙烯‑丙烯酸烷基酯5~8份、二叔丁基过氧化物3~6份、碳酸钙0.1~0.4份、抗氧剂0.2~0.4份、光稳剂0.3~0.5份;由其制备的汽车地毯的制备方法为:称取马来酸酐接枝聚丙烯、乙烯‑丙烯酸烷基酯、碳酸钙、抗氧剂和光稳剂,混合均匀后,置于45~65℃的环境下保温1~2h,随后按重量份加入二叔丁基过氧化物,200~240r/min搅拌2~3h,制得一种低VOC的改性聚丙烯材料,将该材料平铺至基材上,经过冷却、冲压、切割。本申请通过马来酸酐接枝聚丙烯、乙烯‑丙烯酸烷基酯、二叔丁基过氧化物等组分协同配合,从原料源头上解决了VOC释放过多的技术问题。
