Fabric transfer-printing paint and preparation method thereof

The invention discloses a fabric transfer-printing paint and a preparation method thereof. The technical scheme of the transfer-printing paint is that the transfer-printing paint comprises, by mass, 100 parts of epoxy resin-modified polyurethane, 7-12 parts of toluidine-modified dicyandiamide and 3-7 parts of a brightening agent. The molecular weight of the epoxy resin-modified polyurethane is 4500-5500, and the viscosity value of the epoxy resin-modified polyurethane is 1000-2000mPa.s. The paint is a high-performance environment-friendly adhesive with the following advantages and effects: the paint does not contain an organic solvent; when the paint is used in production and processing, toxic organic matter volatilization is avoided, such that worker health is protected, and the atmosphere is not polluted; a solid content of the paint is higher than 90%; when the paint is used in production and processing, efficiency is high; the paint is stable when stored in normal temperature, and is convenient to transfer; the paint has high solid content, and is not prone to volatilization; the paint has good repeatability between batches; the paint can be applied in traditional transfer-printing equipment, such that the paint is convenient to popularize.
