Cement grinding aid containing modified alkali lignin and preparation method thereof
The invention provides a cement grinding aid containing modified alkali lignin. The cement grinding aid comprises the following components in parts by weight: 100-150 parts of modified alkali lignin, 10-15 parts of a reinforcing agent, 1-4 parts of a surfactant and 2-6 parts of a dispersing agent. According to the cement grinding aid containing the modified alkali lignin, the alkali lignin serves as a main raw material, the grinding aiding and enhancing performance of the cement grinding aid on cement clinker and mixed materials is improved through chemical modification, and the lubricating performance of cement can be effectively improved by compounding the alkali lignin with the enhancer, the surfactant and the dispersing agent. According to the preparation method of the cement grinding aid containing the modified alkali lignin, the raw materials are easy to obtain and low in price, the preparation method is simple and easy to implement, reaction conditions are mild, and the preparation method is suitable for industrial production. The cement grinding aid overcomes the technical problems that a traditional cement grinding aid is large in mixing amount and insufficient in layered sedimentation, and the cement quality and durability are affected, and is safe and environmentally friendly to use.
本发明提供了一种含改性碱木质素的水泥助磨剂，所述水泥助磨剂包括以下重量份组分：改性碱木质素100～150份，增强剂10～15份，表面活性剂1‑4份，分散剂2～6份。本发明提供了一种含改性碱木质素的水泥助磨剂，以碱木质素为主要原料，通过化学改性提高其对水泥熟料和混合材料的助磨增强性能，通过与增强剂、表面活性剂和分散剂复配，能有效改善水泥的润滑性性能。本发明提供了一种含改性碱木质素的水泥助磨剂的制备方法，原料易得，价格低廉，制备方法简单易行，反应条件温和，适合工业化生产。本发明克服了传统水泥助磨剂掺量大，分层沉降不足，水泥质量和耐久性助磨剂受影响的技术问题，使用安全环保。
