Abstract

The invention discloses a binder additive and a method for preparing calcium carbide by applying the binder additive. The binder additive is prepared from one of anthracene oil, waste nitrile rubber powder and regenerated phenolic resin particles. The binder additive is wide in raw material source, and therefore the price is low. The calcium carbide raw material prepared from the binder additive has the advantages that not only is the cold strength improved, but also the heat strength is improved to different extents, and the requirements of a novel heat accumulating type high temperature fuel gas melting calcium carbide production technology are met.

Description

technical field

[0001] The invention belongs to the field of calcium carbide chemical industry, and particularly relates to a binder additive and a method for preparing calcium carbide by using the same. Background technique

[0002] China's long-flame coal reserves are huge and cheap, but its utilization has problems such as low efficiency and serious waste. At present, the utilization rate of massive long-flame coal is relatively high, but at the same time, a large amount of powdered long-flame coal is produced, which not only causes huge waste of resources, but also produces certain environmental pollution. Therefore, the utilization of powdered long-flame coal is imminent.

[0003] The new production process of regenerative gas-fired high-temperature molten calcium carbide does not require semi-coke or blue carbon, but directly uses low-rank coal and quicklime as raw materials, and adopts ultra-fine grinding technology to get rid of the "high energy consumption, high emi...
