High-content rock wool by-product steam-cured baking-free brick and preparation method thereof
The invention discloses a high-content rock wool by-product steam-cured baking-free brick and a preparation method thereof. The high-content rock wool by-product steam-cured baking-free brick is prepared from the following raw materials in percentage by weight: 70-85% of rock wool by-product, 14-20% of ordinary cement and 1-10% of special cement, and the ratio of water to the sum of the weight of the ordinary cement and the weight of the special cement is (0.3-0.5): 1. The high-volume rock wool by-product steam-cured baking-free brick is prepared by the following steps: preliminarily mixing and uniformly stirring the rock wool by-product, ordinary cement and special cement according to a mixing ratio, adding a certain amount of water, fully stirring, carrying out compression molding by using a hydraulic brick machine, and carrying out steam curing to obtain the finished product of the baking-free brick. In the invention, the addition amount of the rock wool by-product is more than 70% and is less than 50% higher than the addition amount of waste rock wool in the prior art, the addition amount of noil is high, and the waste of raw materials and the risk of space occupation and pollution caused by solid waste are reduced; the noil is used as the raw material to prepare the rock wool product, and a binder, a water repellent and a coupling agent do not need to be added, so that the production cost is reduced, and the production process is simplified.
本发明公开了一种高掺量岩棉副产物蒸养免烧砖及其制备方法，各原料成分按照如下重量百分比取用：岩棉副产物：70％‑85％，普通水泥：14％‑20％，特种水泥：1％‑10％，用水量与普通水泥和特种水泥重量之和的比例为0.3‑0.5:1。该种高掺量岩棉副产物蒸养免烧砖是将岩棉副产物、普通水泥、特种水泥按配合比初步混合搅拌混匀，加入一定量水充分搅拌，再经液压砖机压制成型、蒸汽养护后得到成品免烧砖。本发明中，岩棉副产物添加量大于70％，高于现有专利技术废岩棉加量小于50％，落棉添加量高，减少了原料的浪费和作为固体废弃物引起的占用空间和污染风险；本发明采用落棉为原料制备岩棉产品，无需再加入粘结剂、憎水剂和偶联剂，降低了生产成本，简化了生产流程。
