Abstract

The invention belongs to the technical field of epoxy resin coatings, and discloses a polyamide modified MoS 2 The preparation method of modified epoxy resin anti-corrosion floor paint, in the present invention, molybdenum disulfide reacts with alkenyl silane coupling agent and polyetheramine in turn, and further reacts with polyetheramine and maleic anhydride respectively, and the obtained product is Cross-linked to obtain cross-linked polyamide-modified nano-molybdenum disulfide, and further obtain polyamide-modified MoS 2 Modified epoxy resin anti-corrosion floor paint, cross-linked polyamide modified nano molybdenum disulfide can be used as a curing accelerator to accelerate the curing of epoxy resin floor paint, promote the uniform dispersion of molybdenum disulfide, cross-linked polyamide modified nano molybdenum disulfide It contains a polyether structure that is easy to rotate, which improves the flexibility, wear resistance and impact resistance of the paint film. At the same time, the benzene ring contained in it will reduce the reactivity of the amino group, improve the hardness and acid and alkali resistance of the paint film. Disulfide Molybdenum fills the micropores of the paint film, and its unique lamellar structure effectively inhibits the penetration of corrosive media.

Description

technical field [0001] The invention relates to the technical field of epoxy resins, in particular to a polyamide-modified MoS 2 The invention discloses a preparation method of a modified epoxy resin anticorrosion floor paint. Background technique [0002] Water-based epoxy resin floor paint is an epoxy resin coating that uses water as the dispersion medium. It not only has excellent mechanical properties of solvent-based epoxy resin coatings, but also can reduce the content of volatile organic compounds and harmful air pollutants. It is safe, environmentally friendly and non-toxic in the process of production, transportation, storage and use, so it has become the widespread concern of researchers in the field of floor paint. However, my country's water-based research in this field is still in its infancy. For example, the Chinese patent disclosure No. CN110240852A patent, which discloses a composite nano-TiO 2 and ZnO water-based epoxy resin floor surface paint, and the pat...
