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 an intumescent high-performance fireproof and flame-retardant coating and a preparation method thereof, belonging to the field of solid waste resource utilization. The coating includes acrylic resin, high chlorinated polyethylene resin, composite catalyst, foaming-char-forming agent, dispersant SRE-4029, turpentine, anti-sedimentation agent, semi-dry desulfurization ash powder; the composite catalyst is boric acid, phosphoric acid A mixture of amidinourea and ammonium polyphosphate; the foaming-char-forming agent is a mixture of melamine and pentaerythritol; the particle size of the semi-dry desulfurization ash powder is 15 μm to 35 μm. The invention not only reduces the production cost of the existing fire-proof and flame-retardant coating by about 30%, but also improves the flame-retardant performance of the fire-proof and flame-retardant coating, realizes the integration of metallurgical solid waste resource utilization and flame-retardant performance in the coating field, and greatly enhances It clarified the market competitiveness and application scope of fire-resistant and flame-retardant coatings; opened up a new idea of ​​"using waste to increase efficiency", which complies with the relevant policy requirements of energy conservation, environmental protection, and circular economy.

Description

technical field [0001] The invention belongs to the field of utilization of solid waste resources, and in particular relates to an intumescent high-performance 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 properties of cal...
