Polycarboxylic acid-containing composite activated cement reinforced grinding aid and preparation method thereof
The invention discloses a composite activated cement reinforced grinding aid containing polycarboxylic acid series. The composite activated cement reinforced grinding aid is prepared from the following raw materials in parts by weight: 50-250 parts of polyethylene glycol maleate, 25-125 parts of an esterifying agent, 70-200 parts of macromonomer allyl polyethylene glycol, 4-20 parts of an initiator, 20-60 parts of a solution and the balance of ionized water, The composite activated cement reinforced grinding aid containing the polycarboxylic acid system can prevent mutual agglomeration of particles, can avoid re-healing of cracks generated on the surfaces of the particles in the grinding process, is beneficial to the crushing process, further has a good grinding aid effect, and is low in cost, non-toxic and harmless, so that environmental pollution is reduced, cost is saved, and popularization is easy.
本发明公开了含聚羧酸系的复合活化水泥增强助磨剂，由如下按重量份原料制成：聚乙二醇马来酸酯50‑250份、酯化剂25‑125份、大单体烯丙基聚乙二醇70‑200份、引发剂4‑20份、溶液20‑60份和余量离子水；该含聚羧酸系的复合活化水泥增强助磨剂能够防止颗粒相互团聚，同时可以避免粉磨过程中颗粒表面产生的裂纹重新愈合，有助于粉碎过程的进行，进而使该助磨剂具有良好的助磨效果，而且本发明成本低，无毒无害，有利于降低环境污染和节约成本，易于推广。
