Abstract

The invention relates to a grinding aid as well as a production process and application thereof, and belongs to the technical field of cement additives. The grinding aid is prepared from the followingraw materials, by weight: 3-7 parts of triethanolamine, 1-9 parts of acetic acid, 1-5 parts of butyltriphenylphosphonium bromide, 85-105 parts of water, 2-8 parts of sodium dodecyl benzene sulfonate,3-7 parts of p-aminophenol, 3-9 parts of acid sophorolipid, 7-13 parts of sodium alginate, 1-7 parts of aminophenol, 6-14 parts of biosurfactant and 10-14 parts of hyperdispersant. The mixing amountof the grinding aid in the cement clinker grinding process is 0.03%-0.05%, and the grinding aid has the effect of improving the cement clinker grinding efficiency so as to reduce the energy consumption in the cement clinker grinding process.

Description

technical field [0001] The invention relates to the technical field of cement additives, in particular to a grinding aid and its production process and application. Background technique [0002] After sending cement clinker and other materials into the ball mill, during the grinding process, due to the gradual refinement of the material particles, the specific surface area increases, and the particles adsorb each other, which is prone to agglomeration, which reduces the grinding efficiency and increases The energy consumption of the grinding process is reduced, so grinding aids are usually added during the grinding process. The grinding aids can prevent particle agglomeration and improve the fluidity of the material, thereby increasing the efficiency of grinding and reducing the energy consumption of the grinding process. [0003] Existing reference number is the Chinese patent of CN103819118A, which discloses a cement grinding aid, the addition of each component is triethan...
