Abstract

The invention discloses an epoxy spray paint and a preparation method thereof. The epoxy spray paint comprises three components A, B and C, wherein the ratio of the three components A, B and C in parts by weight is 100 to 40 to (10-30); the component A comprises the following raw materials in parts by weight: 30-41 parts of epoxy resin, 0.4-0.8 part of a wetting dispersant, 0.2-1 part of a defoaming agent, 4.5-6 parts of a diluent, 52-62 parts of pigments and fillers and 0.5-1 part of a thixotropic agent; the component B comprises the following raw materials in parts by weight: 45-65 parts of a curing agent, 32-45 parts of dimethyl carbonate and 7-15 parts of normal butanol; and the component C comprises the following raw materials in parts by weight: 73-85 parts of dimethyl carbonate and 15-27 parts of normal butanol. According to the epoxy spray paint disclosed by the invention, the harms to physical health of people caused by long-term contact with toluene and xylene are avoided; the pollution to the ambient environment is reduced; and meanwhile, storage of raw materials is facilitated.

Description

technical field [0001] The invention relates to the field of coatings, in particular to an epoxy spray paint and a preparation method thereof. Background technique [0002] Solvent-based epoxy spray paint has excellent electrical insulation properties, mechanical properties and chemical resistance, and the sprayed surface is smooth and smooth. It also has excellent flexibility and good corner coverage, and is widely used in magnetic core spraying. However, epoxy spray paint usually uses highly toxic solvents such as toluene and xylene. Long-term exposure will cause chronic poisoning of the human body, and it will also bring serious pollution to the surrounding environment. Contents of the invention [0003] Based on this, it is necessary to provide an epoxy spray paint that avoids people's long-term exposure to toluene and xylene from endangering health, reduces pollution to the surrounding environment, and has convenient raw material storage. [0004] An epoxy spray pain...
