Efficient powder grinding aid and preparation method thereof
The invention provides an efficient powder grinding aid and a preparation method thereof, and the efficient powder grinding aid comprises the following raw materials by mass: 15-21% of crude glycerin, 13-16% of sodium thiocyanate, 9-16% of ammonium sulfate, 10-14% of triethanolamine, 8-13% of sodium silicate, 5-11% of sorbitol, 8-15% of water glass, and 1-3% of a dispersing agent. According to the invention, the polyhydroxy structures of the triethanolamine and the crude glycerine are added, so that the cement material can be accelerated to be ground and refined after being ground, the strength of the cement after being hydrated is stimulated, and the effects of saving energy, increasing yield and enhancing are achieved. The water glass and the sodium silicate can change the chemical reaction way in the cement hydration process, so that the cement hydration reaction can be carried out at the temperature lower than the normal reaction temperature, and the reaction activation energy is reduced to promote the cement hydration reaction. The added dispersing agent component can effectively promote infiltration between each component and the clinker and increase the contact area of the components and the clinker, so that the respective effects of the components can be more effectively exerted. The efficient powder grinding aid has good energy-saving, coal-saving, yield-increasing and enhancing effects, and is durable in effect, resistant to high temperature, more convenient to use and more environment-friendly.
本发明提供一种粉体高效助磨剂及其制备方法，按质量百分比其原料组成为，粗甘油15‑21％，硫氰酸钠13‑16％，硫酸铵9‑16％，三乙醇胺10‑14％，硅酸钠8‑13％，山梨醇5‑11％，水玻璃8‑15％，分散剂1～3％。本发明添加的三乙醇胺和粗甘油的多羟基结构促使水泥料入磨之后能够加速粉磨细化，激发水泥水化后的强度，达到节能、提产和增强的作用。水玻璃和硅酸钠可以改变水泥水化过程中的化学反应途经，使其能够在低于正常反应温度下发生反应水泥水化反应，降低其反应活化能来促进水泥水化反应。添加的分散剂组分可以有效促进各个组分与熟料之间的浸润和增加其接触面积从而更有效的发挥其各自的作用。具有良好的节能、节煤、提产和增强作用，效果持久耐高温，使用更加方便环保。
