    • A method for water-coating the surface of plastic sheets for interior materials of a vehicle is provided to form a coating film with good thermoforming performance by improving mechanical properties such as luster resistance, scratch resistance, and elongation. A method for water-coating the surface of plastic sheets for interior materials of a vehicle comprises a step for coating the surface of the plastic sheet with a primer composition and then heating and drying the plastic sheet, wherein the primer composition consists of chlorinated water-soluble olefin resin of 30~65wt.%, polyurethane resin of 2~10wt.%, water-soluble silicone resin of 1~5wt.%, a water-soluble stabilizer of 0.5~2wt.%, and the distilled water of 30~60wt.% and a step for applying a thermoplastic polycarbonate urethane composition on a film coated with the primer aqueous solution and then heating and drying the film coated with the thermoplastic polycarbonate urethane composition, wherein the thermoplastic polycarbonate urethane composition consists of aliphatic urethane of 40~60wt.%, aliphatic urethane modifying silicon polyol of 0.1~5wt.%, N-methyl-2-pyrrolidone of 3~5wt.%, a neutralizing agent of 0.1~1wt.%, and the distilled water of 30~60wt.%.
    • 提供一种用于对车辆内部材料的塑料片的表面进行水涂覆的方法,通过改善诸如耐光泽性,耐擦伤性和伸长率的机械性能来形成具有良好热成型性能的涂膜。 用于对车辆内部材料的塑料片的表面进行水涂覆的方法包括用底漆组合物涂覆塑料片的表面,然后加热和干燥塑料片的步骤,其中底漆组合物由氯化水 - 可溶性烯烃树脂为30〜65重量%,聚氨酯树脂为2〜10重量%,水溶性硅树脂为1〜5重量%,水溶性稳定剂为0.5〜2重量%,蒸馏水为30〜 60重量%的热塑性聚碳酸酯聚氨酯组合物,以及在涂布有底漆水溶液的薄膜上涂布热塑性聚碳酸酯聚氨酯组合物,然后加热干燥涂布有热塑性聚碳酸酯聚氨酯组合物的薄膜的步骤,其中热塑性聚碳酸酯聚氨酯组合物由40〜 60重量%,脂肪族氨基甲酸酯改性硅多元醇0.1〜5重量%,N-甲基-2-吡咯烷酮3〜5重量%,中和剂0.1〜1重量%,蒸馏水30〜60重量% 。
