The invention provides a polyformaldehyde composite material, a preparation method and an elevator door sill prepared by the polyformaldehyde composite material. The polyformaldehyde composite material comprises a first sill part and a second sill part, the right side plate of the first sill part and the left side plate of the second sill part are arranged in parallel, and the bottoms are connected into a whole through a connecting plate to form a sliding groove with an upward opening. The invention further provides the polyformaldehyde composite material for processing the elevator door sill.The equipment weight is greatly reduced, installation and transportation are facilitated, transportation cost is effectively reduced, field carrying is facilitated, installation is more convenient, high environmental protection cost caused by aluminum alloy and carbon steel machining is avoided, and energy conservation and environmental protection are facilitated. The invention further provides aproduct made of the polyformaldehyde composite material, and the product is formed by injection molding of the polyformaldehyde composite material.

    本发明提供了一种聚甲醛复合材料及制备方法及制成的电梯门地坎,包括第一地坎部和第二地坎部;所述第一地坎部的右侧板和所述第二地坎部的左侧板并列设置,底部通过连接板连接成一体,形成开口向上的滑槽。本发明还提供了一种加工如前所述的电梯门地坎的聚甲醛复合材料。大大减轻设备重量,方便安装运输,有效降低运输费用,方便现场搬运,安装更加方便,避免铝合金及碳钢加工所带来的高昂的环保成本,有利于节能环保。还提供了一种聚甲醛复合材料制成的制品,由如前所述的聚甲醛复合材料材料注塑而成。
