The invention provides an automobile sun shield and a preparation method thereof. The automobile sun shield comprises a first decorative fabric layer, a first non-ventilation film layer, a first localglass fiber material layer, a first integral glass fiber material layer, a base body layer, a second integral glass fiber material layer, a second local glass fiber material layer, a second non-ventilation film layer and a second decorative fabric layer which are sequentially stacked. The first local glass fiber material layer, the first integral glass fiber material layer, the base body layer, the second integral glass fiber material layer and the second local glass fiber material layer are bonded through adhesives. The automobile sun shield is obtained through the steps that all layers of materials are pretreated and then laid in sequence, and hot press molding and cooling shaping are conducted. The sun shield provided by the invention not only can meet the overall high-strength performance index of the automobile skylight sun shield, but also can effectively reduce the overall weight of the sun shield and reduce the cost.
