Abstract

The invention relates to a preparation method and application of nano barium sulphate. The preparation method of the nano barium sulphate concretely comprises that barium ions and sulphate ions in specified concentration are added into electrolyte from an anode and a cathode of an electrolysis cell respectively, move at high speed under the action of an electric field by utilizing charged ions and collide to generate barium sulphate precipitate, wherein reaction is quick and intense, then filtering and drying are carried out, so that flaky nano barium sulphate with fine grain size, uniform grain size distribution and stable performance are obtained, and the flaky nano barium sulphate can effectively reflect infrared rays in the sunlight and transmit visible lights when being applied to transparent reflective thermal insulation coating, so that transmitting and thermal insulating functions are realized. The preparation method of the nano barium sulphate is simple, reliable, high in efficiency and good in effect, product quality is stable, and industrial production can be easily realized.

Description

technical field [0001] The invention relates to the field of inorganic non-metallic mineral materials, in particular to a preparation method and application of nanometer barium sulfate. Background technique [0002] Barium sulfate is one of the most important inorganic chemical products nowadays. It has the advantages of strong chemical inertness, good stability, acid and alkali resistance, moderate hardness, high specific gravity, high whiteness, and ability to absorb harmful rays. It is widely used in rubber, plastics, coatings, It is widely used in medicine and other industries, and is also used as a weighting agent for oil and natural gas drilling mud. [0003] With the development and utilization of new functional devices and the vigorous development of the material industry, barium sulfate, as an important raw material in many industries, has not only expanded its application fields, but also significantly increased its quality requirements. In recent years, many coun...
