The invention discloses an automobile skylight composite fabric and a preparation method thereof.The preparation method comprises the steps that an ultraviolet absorbent and a flame retardant are added into waterborne polyurethane and stirred and mixed to be uniform, and treating fluid is obtained; and uniformly coating two surfaces of the needle-punched polypropylene non-woven fabric with the treating fluid, and performing hot-pressing treatment to obtain the needle-punched polypropylene non-woven fabric. The composite fabric can be used for processing automobile skylight sunshade curtains, and is high in shading rate and good in flame retardant effect. The preparation method of the ultraviolet absorbent comprises the following steps: firstly, taking nano titanium nitride and a cerous nitrate solution as raw materials to react to prepare surface modified titanium nitride, then carrying out primary grinding on 1, 2, 4-benzotriazine, suriphenone and polymethyl acrylate, adding the surface modified titanium nitride, and continuously grinding to obtain the ultraviolet absorbent. The preparation method of the flame retardant comprises the following steps: preparing intercalated alpha-zirconium phosphate by taking layered alpha-zirconium phosphate, zinc acetylacetonate and cobalt acetylacetonate as raw materials, and carrying out modification treatment to obtain modified alpha-zirconium phosphate; and mixing the modified alpha-zirconium phosphate with dipentaerythritol phosphate and expanded graphite to react, thereby obtaining the modified alpha-zirconium phosphate.

    本发明公开了一种汽车天窗复合面料及其制备方法,将紫外吸收剂、阻燃剂加入水性聚氨酯中,搅拌混匀,得到处理液;将处理液均匀涂布在针刺聚丙烯无纺布的两个表面,热压处理,即得。该复合面料可用于汽车天窗遮阳帘加工,遮光率高,阻燃效果好。其中,紫外吸收剂的制备方法如下:先以纳米氮化钛与硝酸铈溶液为原料反应制成表面修饰氮化钛,然后将1,2,4‑苯并三嗪、舒利苯酮、聚丙烯酸甲酯进行初步研磨,加入表面修饰氮化钛后继续研磨,即得。阻燃剂的制备方法如下:先以层状α‑磷酸锆、乙酰丙酮锌、乙酰丙酮钴为原料,制成插层α‑磷酸锆,改性处理,得到改性α‑磷酸锆;再将改性α‑磷酸锆与二季戊四醇磷酸酯、膨胀石墨混合反应,即得。
