The invention relates to the field of automotive interiors, and particularly discloses a modified low-atomization polyvinyl chloride automotive interior skin and a preparation method thereof. The modified low-atomization polyvinyl chloride automotive interior skin comprises a surface layer, a modified polyvinyl chloride layer and a base cloth layer, the modified polyvinyl chloride layer is located between the surface layer and the base cloth layer, and the modified polyvinyl chloride layer is prepared from, by weight, 10-20 parts of modifier, 50-65 parts of polyvinyl chloride resin, 1.5-2.5 parts of stabilizer and 30-40 parts of high-temperature plasticizer. 0.3-3 parts of a flame retardant; the modifier is a mixture of polyethylene glycol phosphate and an acrylate copolymer. According to the prepared interior trim skin, release of volatile substances can be reduced through the polyethylene glycol phosphate and the acrylate copolymer, the atomization degree of the polyvinyl chloride interior trim skin is reduced, and meanwhile the strength and the weather resistance of the interior trim skin are improved.

    本申请涉及汽车内饰领域,具体公开了一种改性低雾化聚氯乙烯车用内饰表皮及其制备方法。一种改性低雾化聚氯乙烯车用内饰表皮,包括表层、改性聚氯乙烯层和基布层,所述改性聚氯乙烯层位于表层和基布层之间,所述改性聚氯乙烯层包括以下重量份的原料:改性剂10‑20份,聚氯乙烯树脂50‑65份,稳定剂1.5‑2.5份,高温增塑剂30‑40份,阻燃剂0.3‑3份;所述改性剂为聚乙二醇磷酸酯和丙烯酸酯共聚物的混合物。本申请制备的内饰表皮通过聚乙二醇磷酸酯和丙烯酸酯共聚物能够减少挥发性物质的释放,降低聚氯乙烯内饰表皮雾化度,同时提高内饰表皮强度和耐候性能。
