Example Embodiment

[0019] Example 1

[0020] A high-efficiency composite powder grinding aid, comprising the following parts by weight of raw materials: 0.8 parts of triethanolamine, 1 part of polyol, 0.3 parts of sodium thiocyanate, 0.8 parts of PC water reducer stock solution, 0.3 parts of sodium hydroxide and steel slag 94 copies. The polyol uses a mixture of pentaerythritol and trimethylolethane.

[0021] The specific steps of the preparation method of the high-efficiency composite powder grinding aid are as follows:

[0022] Step 1: Add triethanolamine, polyol and PC water reducer stock solution to the stirring tank in sequence and fully mix and react for 2 hours to obtain a mixed solution;

[0023] Step 2: The steel slag, sodium hydroxide and sodium thiocyanate are thoroughly mixed and then added to the mixed solution, mixed evenly to obtain the finished product.

Abstract

The invention discloses an efficient composite powder grinding aid and a preparation method thereof. The efficient composite powder grinding aid comprises the following raw materials in parts by weight: 0.8-1.5 parts of triethanolamine, 1-1.8 parts of polyalcohol, 0.3-0.6 part of sodium thiocyanate, 0.8-1.5 parts of a PC water reducing agent raw liquor, 0.3-0.4 part of sodium hydroxide and 94-97.5parts of steel slags. The efficient composite powder grinding aid disclosed by the invention is extensive in raw material sources; through compounding of various raw materials, organic compounds arenot used, and the difficult problem that the organic compounds are nonserviceable due to decomposition of components is effectively solved; the prepared finished products are harmless to cement and human bodies, and conform to the standard of relevant addition of grinding aids in China; and the product namely the efficient composite powder grinding aid is low in cost and stable in quality, the yield of the cement can be increased, the early intensity of the cement can be increased, the grinding aiding effect is good, and the application prospects are great.

Description

technical field [0001] The invention relates to the field of cement, in particular to a high-efficiency composite powder grinding aid. Background technique [0002] The construction industry is an industry that revolves around the design, construction, decoration, and management of buildings. Urban architecture is an important part of the construction industry. Urban architecture inherits culture in its unique way, spreads the charm of life, and continuously penetrates into the In people's daily life, create a harmonious and peaceful spiritual home for people. [0003] Building materials are a general term for materials used in urban construction. Building materials can be divided into structural materials, decorative materials and some special materials. Cement is a common building material. [0004] Cement is a powdery hydraulic inorganic gelling material. After adding water and stirring, it becomes a slurry, which can be hardened in the air or better hardened in water,...
