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-adhesion fireproof and flame-retardant paint and a preparation method thereof, belonging to the field of paint. The coating includes acrylic resin, high chlorinated polyethylene resin, composite catalyst, foaming-char-forming agent, dispersant, turpentine, anti-sedimentation agent, semi-dry desulfurization ash micropowder, calcium sulfate whisker; the composite catalyst is boric acid , a mixture of guanylurea phosphate and ammonium polyphosphate; the foaming-char-forming agent is a mixture of melamine and pentaerythritol; Calcium sulfate whiskers. The invention not only reduces the production cost of the existing fire retardant coating, but also improves the adhesion of the fire retardant coating, realizes the integration of high adhesion and flame retardant performance in the coating field, and greatly enhances the market competition of the fire retardant coating Power and application range, in line with the relevant policy requirements for energy conservation, environmental protection, and circular economy.

Description

technical field [0001] The invention belongs to the field of coatings, and in particular relates to an intumescent high-adhesion 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 calcium sulfite in the semi-dry de...
