Description
Technical Field
The invention relates to the field of chemical coatings, in particular to an ultra-fast-drying solvent-free epoxy micaceous iron coating and a preparation method and application thereof.
Background
Fillers such as epoxy resin and micaceous iron oxide are used in conventional epoxy micaceous iron oxide coatings. The epoxy resin contains ether bonds and carboxyl groups which are strong polar groups, and the groups can enable epoxy resin molecules and the surface of a base material to generate strong adhesive force, so that the preparation and the performance of the paint are greatly influenced by selecting the epoxy resin with low viscosity and organic chlorine content. The mica iron oxide, the mica powder and the antirust material are usually selected as main filling materials, and the mica iron oxide and the mica powder have a flaky structure, so that the mica iron oxide and the mica powder have a good shielding effect in the paint and can effectively isolate the permeation of an anticorrosive medium.
At present, the Chinese patent with publication No. CN103409039A named as an epoxy micaceous iron paint discloses that the epoxy micaceous iron paint is modified by nano clay and consists of the following two components; the first component comprises the following components in parts by weight: 10-55 parts of epoxy resin; 5 to 65 portions of mica iron oxide; 0.02-18 parts of fatty amine; 0.1 to 25 portions of clay; 1.0 to 70 portions of solvent; the cosolvent 1.5-5, the second component, comprises the following components and contents (parts by weight): 10-75 parts of solvent; 25-90 parts of curing agent; the ratio of the first component to the second component is 100: 10-100: 80; the clay is intercalated and has a particle size of 200-2000 meshes.
However, the currently used coating has the following problems:
1. the epoxy curing agent used by the prior epoxy micaceous iron coating mainly comprises fatty amine and polyamide, wherein the fatty amine has slow dryness due to poor chemical resistance; the polyamide curing agent has excellent adhesive force and chemical resistance due to the large molecular weight, but the solid content is generally not high, so that the polyamide curing agent is not suitable for a solvent-free system.
2. The conventional epoxy micaceous iron oxide coating uses the combination of epoxy resin and clay, is matched with a fatty amine fixing agent, has higher viscosity, and needs to add a large amount of diluents in the construction process, so the conventional epoxy micaceous iron oxide coating has large discharge amount of Volatile Organic Compounds (VOC), is not environment-friendly and has relatively slow dryness.
