Problems solved by technology

Semi-dry desulfurization waste The composition of the semi-dry desulfurization ash is extremely complex, consisting of desulfurizers, desulfurization products and fly ash (the main chemical components are 59.24% CaO, 59.24% SO 3 32.12%, Cl 3.21%, Fe 2 o 3 1.75%), and the properties of calcium sulfite in the semi-dry desulfurization ash are very unstable, so the current semi-dry desulfurization ash is mainly stacked and discarded, which not only takes up a lot of land but also causes further environmental pollution

Abstract

The invention discloses a metallurgy solid-waste-type fireproof and flame-retarding coating and a preparing method thereof, and belongs to the field of metallurgy solid-waste resource utilization. Thecoating is prepared from acrylic resin, high chlorinated polyethylene resin, a compound catalyst, a foaming agent, a charring agent, a pro-oxygenic agent, a dispersing agent, turpentine, an anti-precipitation agent and a semi-dry-process desulfurized fly ash micro powder solution; the compound catalyst is a mixture of boric acid, amidinourea phosphate and ammonium polyphosphate; the semi-dry-process desulfurized fly ash micro powder solution is a mixture of semi-dry-process desulfurized fly ash micro powder and water. By means of the metallurgy solid-waste-type fireproof and flame-retarding coating, about 25% of production cost of an existing fireproof and flame-retarding coating is lowered, the flame-retarding performance of the fireproof and flame-retarding coating is improved, integration of metallurgy solid-waste resource utilization and flame-retarding performance in the field of coatings is achieved, the market competitiveness of the fireproof and flame-retarding coating is greatly enhanced, and the application range of the fireproof and flame-retarding coating is greatly enlarged; high-added-value application of the semi-dry-process desulfurized fly ash is achieved, a new idea of synergism with waste is expanded, and the relevant policy for energy saving, environmental friendly and circular economy is accorded with.

Description

technical field [0001] The invention belongs to the field of utilization of metallurgical solid waste resources, and in particular relates to a metallurgical solid waste fireproof and flame-retardant coating and a preparation method thereof. Background technique [0002] As my country controls and reduces SO 2 With the continuous increase of emissions, flue gas desulfurization has entered a stage of rapid development. With the successive installation of desulfurization devices, there are more and more desulfurization products. Among them, the semi-dry desulfurization technology has a remarkable desulfurization effect and is widely used in the desulfurization process of steel mills in my country. Semi-dry desulfurization waste The composition of the semi-dry desulfurization ash is extremely complex, consisting of desulfurizers, desulfurization products and fly ash (the main chemical components are 59.24% CaO, 59.24% SO 3 32.12%, Cl 3.21%, Fe 2 o 3 1.75%), and the propert...
