Abstract

The invention relates to safe and environment-friendly aluminum powder and a preparation method thereof, in particular to safe and environment-friendly aluminum powder for refractory industry. The safe and environment-friendly aluminum powder is composed of aluminum powder, OP-10 and dimethicone. The preparation method includes sequentially adding a solvent, dimethicone and OP-10 into a stirring tank; stirring while adding the aluminum powder; after reaction is completed, filtering the aluminum powder, and discharging and packaging after volatile content is inspected to be qualified. Generally, volatile content is smaller than or equal to 1%o. The safe and environment-friendly aluminum powder is mainly used for manufacturing of high-alumina refractories like plugs and nozzle bricks for constructing a blast furnace, a hot blast furnace, an electric furnace roof, an air furnace, a reverberatory furnace, a rotary kiln lining, an open furnace heat-storage-type checker brick and a pouring system. The safe and environment-friendly aluminum powder mainly has the advantages of being free of dusting, environmental pollution and reaction when contacting with water, free of clotting, easy to disperse and safe to use and store.

Description

technical field [0001] The invention relates to a safe and environment-friendly aluminum powder, in particular to a safe and environment-friendly aluminum powder used in the refractory industry and a preparation method thereof. Background technique [0002] Traditional high-alumina refractories use untreated atomized aluminum powder. Although the technical indicators meet the production requirements, there are obvious deficiencies in the following aspects. First of all, metal dust is generated during use, and production workers are prone to pneumoconiosis. Due to the excessive dust concentration at the production site, dust explosions are likely to occur, and at the same time pollute the environment. Secondly, due to the reaction of aluminum powder with water, the product is easy to absorb moisture and agglomerate during storage. , resulting in material scrap. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a sa...
