Problems solved by technology

Semi-dry desulfurization waste The composition of semi-dry desulfurization ash is extremely complex, consisting of desulfurization agent, 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

Belonging to the field of paint, the invention discloses an intumescent and fire retardant paint with high adhesion and a preparation method thereof. The paint comprises acrylic resin, high chlorinated polyethylene resin, a composite catalyst, a foaming-charring agent, a dispersant, turpentine oil, an anti-settling agent, semi-dry desulfurization ash micropowder, and calcium sulfate whisker. The composite catalyst is a mixture of boric acid, amidinourea phosphate and ammonium polyphosphate; the foaming-charring agent is a mixture of melamine and pentaerythritol; the calcium sulfate whisker is prepared from semi-dry desulfurization ash as the raw material by hydrothermal oxidation process. The method provided by the invention not only reduces the production cost of the existing fire retardant paint, but also improves the adhesion of the fire retardant paint, realizes the integration of high adhesion and fire retardant performance in the paint field, greatly enhances the market competitiveness and application scope of fire retardant paint, and conforms to the related policy requirements of 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 semi-dry desulfurization ash is extremely complex, consisting of desulfurization agent, 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 calcium sulfite in the semi-dry desulfurizat...
