Method for preparing regenerated polypropylene fibers from waste masks
The invention belongs to the technical field of building materials, and particularly relates to a method for preparing regenerated polypropylene fibers from waste masks. The used material is the waste mask, and the waste mask is sterilized and then subjected to high-temperature and high-pressure treatment to finally prepare the regenerated polypropylene fiber. The regenerated fiber prepared from the waste masks can be used as a concrete reinforcing material, the compressive strength and tensile strength of concrete can be improved after the regenerated fiber is added into the concrete, the used materials are wastes, the loss of raw materials is reduced, the problem of environmental pollution is relieved, and the regenerated fiber has very high use value.
本发明属于建筑材料技术领域，具体涉及废弃口罩制备成再生聚丙烯纤维的方法。本发明使用的材料是废弃口罩，废弃口罩经过消杀后，对其进行高温高压处理，最终制成再生聚丙烯纤维。废弃口罩制成的再生纤维掺可以用作混凝土增强材料，其加入到混凝土中，可以改善混凝土的抗压强度和抗拉强度，而且使用的材料也是废弃物，不仅减少了原材料的损耗，也缓解了环境污染问题，具有很高的使用价值。
