Abstract
The invention discloses a special grinding aid for conductive cement and a preparation method and application thereof. The special grinding aid is prepared from the following raw materials in percentage by weight: 17-25% of grinding aid mother liquor, 3-7% of conductive polyaniline, 5-9% of polystyrene, 8-15% of basalt fiber, 4-9% of iron ore powder, 3-5% of polyvinylpyrrolidone and the balance ofconductive fly ash, totaling 100%, wherein the percentages are mass percentages. The basalt fibers and the polystyrene are used so that the tensile strength, the crack resistance and the toughness ofthe composite cement material can be improved. The polyvinylpyrrolidone foam stabilizer is used for preparing the lightweight conductive cement. The polyaniline can reduce the resistance of the conductive cement and increase the conductivity, thereby reducing the doping amount of graphite and other conductive materials. The conductive cement grinding aid is good in chemical stability, does not contain halogen ions which corrode equipment, remarkably improves the grinding efficiency, early strength and later strength of cement, and effectively improves the conductivity and the durability of the conductive cement.
Description
technical field [0001] The invention belongs to the technical field of conductive cement production, and in particular relates to a special grinding aid for conductive cement and its preparation method and application. Background technique [0002] In the production and use of military products, vicious accidents caused by static electricity occur from time to time. For example, when an arsenal was testing a product, the product exploded due to the static electricity carried by the worker's body, and one person was injured; when the crystalline lead nitride was divided into plates in a chemical factory, a rubber rake was used to rake the crystalline lead nitride whose purity was unqualified and repaired. An explosion occurred during flat operation; a torpedo was misfired due to a strong electromagnetic field on a navy ship; a rocket of a certain army flew out of a packing box in a thunderstorm, etc. The elimination of static electricity in the construction facilities of tex...
