Abstract

The invention discloses a high-solid anticorrosive paint and a preparation method thereof. The high-solid anticorrosive paint is prepared by adopting converter dust ash as filler and adding resin, a curing agent and diluents. The converter dust ash can be used as filler without being milled, and the common filler which is used as the anticorrosive paint is extremely high in cost due to such requirements as grain size, and so the high-solid anticorrosive paint can be used as filler of the anticorrosive paint, and the value-added effect of the high-solid anticorrosive paint is very obvious. From the energy-saving emission-reducing angle, the converter dust ash can be used as the material of the anticorrosive paint; and corrosion prevention is very important to prolonging of the life cycle of the steel product, so great contributions are made to low-carbon economy and resource conversation.

Description

technical field [0001] The invention relates to a paint, in particular to a high-solid anticorrosion paint and a preparation method thereof. Background technique [0002] On the one hand, iron and steel enterprises are large energy consumers, and on the other hand, they are also large polluters due to the large amount of "three wastes" discharged during the production process. Iron and steel enterprises will produce a large amount of dust and by-products in the production process, which is called dust removal. Iron and steel enterprises mainly include blast furnace ash, converter ash, electric furnace ash and self-produced dedusting ash in the sintering process. If the dust is not treated and utilized, it will seriously pollute the environment, endanger human health, and waste a lot of precious resources. "Powder Metallurgy Technology" 2002 Issue 01 Gao Jiacheng et al. "Research on Extracting Iron Powder from Converter Dust" analyzed the basic physical properties of the co...
