Problems solved by technology

However, at present, epoxy resin fire-resistant coatings are used as the surface coating of steel structures without considering its anti-fouling performance. Stains are easy to adhere to the surface and cannot be cleaned, which greatly affects the corrosion resistance and aesthetics of steel structures.

Abstract

The invention provides an anti-staining epoxy fire-retardant coating and a preparation method thereof. The fire-retardant coating is prepared by mixing a component A and a component B, wherein the component A is prepared by the following ingredients of, by weight, 40-45% of a water-borne epoxy resin, 15% of modified ammonium polyphosphate, 6-8% of trimeric cyanamide, 6-8% of pentaerythritol, 3-7% of nano TiO2, 3-5% of nano silica, 3-7% of an organic silane coupling agent, 10-15% of brucite fibers and a proper amount of water, a total weight percentage of all the ingredients of the A component is 100%; and the component B is a curing agent accounting for 10% of the weight of the water-borne epoxy resin. The anti-staining epoxy fire-retardant coating prepared by the method has the functions of water-based environment protection, good anti-staining performance, capacity for resisting water immersion for a long time and long fire endurance. The anti-staining epoxy fire-retardant coating can not only resist stains and prevent fire, and has the function of sound absorption.

Description

technical field [0001] The invention belongs to the technical field of fireproofing materials, and in particular relates to an antifouling epoxy fireproofing coating and a preparation method thereof. Background technique [0002] At present, some active components of intumescent fireproof coatings used in China will slowly precipitate under wet conditions, which affects the fireproof effect. A large number of experiments have confirmed that epoxy resin is the best film former for fire retardant coatings, especially on rigid surfaces outdoors and indoors. This is because epoxy resin not only has excellent impact strength, sealability, adhesion and moisture resistance, but also can be used as a carbon forming agent for intumescent fireproof coatings. After a fire occurs, the coating can remain intact and adhere on the substrate. However, at present, epoxy resin fire-resistant coatings are used as the surface coating of steel structures without considering its anti-fouling pe...
