The invention discloses a light-weight car trunk carpet and a preparation method thereof, and the preparation method comprises the following steps: (1) preparation of a surface layer non-woven fabric: taking unsaturated polyester to react with sulfydryl polysiloxane to obtain modified polyester; spinning the modified polyester to obtain a modified polyester fiber; mixing the modified polyester fibers, and performing spunlace to obtain a non-woven fabric; immersing the non-woven fabric in slurry, and drying to obtain a surface layer non-woven fabric; and (2) preparing the car trunk carpet: respectively placing two layers of surface layer non-woven fabrics on the upper surface and the lower surface of an inner cavity of a mold, and injecting a polypropylene foaming material into the inner cavity of the mold to obtain the car trunk carpet. The preparation method comprises the following steps: preparing hydroxyl-containing unsaturated polyester from dibasic acid and unsaturated dihydric alcohol, sequentially reacting with ABS, allyl glycidyl ether and sulfydryl polysiloxane, preparing modified polyester, spinning, spunlacing and dipping slurry to obtain a surface layer non-woven fabric, and compounding the surface layer non-woven fabric with a polypropylene foaming material to obtain the high-toughness, wear-resistant and light-weight trunk carpet.
本发明公开了一种轻量化汽车行李箱地毯及其制备方法,包括以下工艺:(1)表层无纺布的制备:取不饱和聚酯与巯基聚硅氧烷反应,得到改性聚酯;取改性聚酯进行纺丝,得到改性聚酯纤维;取改性聚酯纤维混合,水刺,得到无纺布;将无纺布浸浆,干燥,得到表层无纺布;(2)汽车行李箱地毯的制备:取两层表层无纺布分别放置在模具内腔的上表面和下表面,向模具内腔注塑聚丙烯发泡材料,得到行李箱地毯。本发明通过二元酸、不饱和二元醇制备含羟基不饱和聚酯,依次与ABS、烯丙基缩水甘油醚、巯基聚硅氧烷反应,制备改性聚酯,纺丝、水刺,浸浆,得到表层无纺布,与聚丙烯发泡材料复合,获得高强韧、耐磨且轻量的行李箱地毯。
