Polypropylene floor and preparation equipment thereof
The invention provides a polypropylene floor and preparation equipment thereof.The polypropylene floor comprises a decorative composite layer and a composite base material layer, the composite base material layer comprises a first base material layer and a second base material layer which are sequentially arranged, and the decorative composite layer is arranged on the side, away from the second base material layer, of the first base material layer; the first base material layer is prepared from the following raw materials in percentage by weight: 60-80% of inorganic filler, 18-38% of polypropylene resin and 1-5% of auxiliaries, and the second base material layer is prepared from the following raw materials in percentage by weight: 0-50% of inorganic filler, 50-98% of polypropylene resin and 1-5% of auxiliaries. The thermal deformation of the decorative composite layer and the second base material layer on the two sides of the first base material layer is larger than that of the first base material layer, so that the directions of acting force applied to the first base material layer by the decorative composite layer and the second base material layer are opposite, and the acting force is counteracted; therefore, the polypropylene floor comprising the decorative composite layer, the first base material layer and the second base material layer is not easy to bend and deform when heated.
本发明提供一种聚丙烯地板及其制备设备，聚丙烯地板包括装饰复合层和复合基材层，复合基材层包括依次设置的第一基材层和第二基材层，装饰复合层设置于第一基材层远离第二基材层的一侧，按质量百分比计，所述第一基材层的制备原料包括60‑80％无机填料，18‑38％聚丙烯树脂，1‑5％助剂，所述第二基材层的制备原料包括0‑50％无机填料，50‑98％聚丙烯树脂，1‑5％助剂，本申请的第一基材层两侧的装饰复合层和第二基材层受热变形均比第一基材层的受热变形大，使得装饰复合层和第二基材层给第一基材层施加的作用力方向相反，以进行抵消，从而使得包括装饰复合层、第一基材层和第二基材层的聚丙烯地板受热不易弯曲变形。
