Abstract

The invention discloses an additive for improving cement performance. The additive is mainly prepared from, by mass, 4-6 parts of ethylene diamine tetra(methylene phosphonic acid)sodium, 2-5 parts of molasses, 2-4 parts of sodium thiosulfate, 1-3 parts of sodium hexametaphosphate, 1-2 parts of amino-tri(methylene phosphonic acid)sodium, 0.5-1.5 parts of N,N-diisopropylethanolamine, 0.2-0.8 part of triisopropanolamine, 1-2 parts of used oil, 0.1-0.4 part of dipropylene glycol, 0.2-0.6 part of glycerol, 0.5-1.0 part of urea, 0.1-0.4 part of calcium lignosulphonate, 0.3-0.6 part of borax, 0.4-0.8 part of dioctyl phthalate, 0.1-0.3 part of dibutyl phthalate, 0.2-0.4 part of zinc stearate and 0.2-0.4 part of a surfactant Tween-80. The product is easy and convenient to prepare, good in reinforcing effect and capable of improving the efficiency of a pulverizer, reducing energy consumption and reducing the factory production cost.

Description

technical field [0001] The invention relates to the technical field of cement admixtures, in particular to an additive for improving cement performance and a preparation method. Background technique [0002] Cement additive is a chemical additive to improve the grinding effect and performance of cement, which can significantly increase the output of cement grinding table and the strength of cement at various ages. Cement additives can greatly reduce the phenomenon of electrostatic adsorption and encapsulation formed in the grinding process, and can reduce the tendency of re-agglomeration of ultrafine particles formed in the grinding process, reducing the phenomenon of over-grinding. Cement additives can also significantly improve the fluidity of cement, improve the grinding efficiency of the mill and the powder selection efficiency of the powder separator, thereby reducing the energy consumption of grinding. As a chemical activator, cement additives can improve the distribu...
