The invention discloses Portland cement and a preparation method thereof. The Portland cement comprises the following raw materials in parts by weight: 50-60 parts of Portland cement clinker, 10-15 parts of graphite polyphenyl granules, 5-6 parts of limestone, 7-10 parts of kapok fibers, 4-6 parts of gypsum powder, 1-3 parts of silicon dioxide, 1.5-2 parts of a foaming agent and 35-45 parts of water. The preparation method comprises the following steps of: mixing and grinding Portland cement clinker, graphite polyphenyl granules, limestone and kapok fibers to obtain a mixture A, then adding the mixture A and water into a high-speed stirrer for secondary mixing to obtain a mixture B, then adding the mixture B, gypsum powder and silicon dioxide into a mixing stirrer for mixing to obtain a mixture C, and finally adding the mixture C and a foaming agent into a mixing stirrer for mixing. According to the Portland cement and the preparation method thereof, the graphite polyphenyl granules, the kapok fibers and the foaming agent are added, so that the Portland cement has the effects of efficient isolation and convenient heat preservation, and the Portland cement is relatively low in production cost, simple and rapid in process and suitable for popularization and application.
本发明公开了一种硅酸盐水泥及其制备方法，按重量份数计，其原料包括硅酸盐水泥熟料50‑60份、石墨聚苯颗粒10‑15份、石灰石5‑6份、木棉纤维7‑10份、石膏粉4‑6份、二氧化硅1‑3份、发泡剂1.5‑2份、水35‑45份；制备方法如下：将硅酸盐水泥熟料、石墨聚苯颗粒、石灰石和木棉纤维进行混合研磨，得到混合物A，然后将混合物A和水加入高速搅拌机中进行二次及混合，得到混合物B，再将混合物B、石膏粉和二氧化硅加入混合搅拌机中混合，得到混合物C，最后将混合物C和发泡剂放入混合搅拌机中混合。本发明一种硅酸盐水泥及其制备方法中，通过加入石墨聚苯颗粒、木棉纤维和发泡剂，具有高效隔离和便于保温的效果，而且本发明生产成本较低，流程简单快捷，适合推广使用。
