Environment-friendly filler prepared from waste cellulose acetate fibers as well as preparation method and application of environment-friendly filler
The invention discloses an environment-friendly filler prepared from waste cellulose acetate fibers, a preparation method and application, the filler is prepared by mixing a cementing material, water, the waste cellulose acetate fibers and a fluid-solid phase change agent, the water and the waste cellulose acetate fibers are mixed to obtain a mixture A, then the water and the cementing material are mixed to obtain a mixture B, and the mixture B is mixed to obtain a mixture B; the mixture A and the mixture B are mixed and stirred and then mixed with a fluid-solid phase change agent, and the environment-friendly filler is obtained; the prepared environment-friendly filling material is used for filling a large-space goaf; the raw materials are green and environment-friendly and wide in source, the prepared environment-friendly filler is not segregated in fluid and solid phases and good in water-retaining property, and the problems that in the prior art, the usage amount of waste cellulose acetate fibers is small, the production cost is high, the added value of products is low, large-scale recycling cannot be achieved, and high economic benefits cannot be achieved are solved.
一种废弃醋酸纤维制备的环保型填充料、制备方法及应用，所述填充料利用胶凝材料、水、废弃醋酸纤维和流固变相剂通过混合制备而成，先将水和废弃醋酸纤维得到混合物A，再将水和胶凝材料混合得到混合物B，混合物A和混合物B混合搅拌后与流固变相剂混合，得到环保型填充料；制备得到的环保型填充料用于大空间型采空区填充；本发明取材绿色环保、来源广泛，制备的环保型填充料流固两相不离析、保水性好，解决了现有技术中对于废弃醋酸纤维的使用量均较小，生产成本高且产品的附加值低，无法实现大规模的再生利用和较高的经济效益的问题。
