Abstract
The invention discloses a microcapsule paint containing dye and a preparation method thereof. The microcapsule paint comprises, by mass, 20 parts to 60 parts of microcapsules, 5 parts to 20 parts of adhesives and 100 parts to 250 parts of water. Each microcapsule comprises a core material and a capsule wall wrapping the core material, wherein the core material comprises solvents and the oily dye, and the capsule wall is made of waterborne substances. Each microcapsule comprises, by mass, 8 parts to 20 parts of the solvents, 1 part to 3 parts of the oily dye and 11 parts to 37 parts of the capsule wall. By means of the wrapping effect of the capsule walls, the dye which is prone to volatilization and degeneration is protected in the capsule walls, and it is avoided that the dye is exposed in air and is damaged; when the dye needs to be used, the dye is extruded out of the microcapsules through extrusion or sliding pressing and can then be transferred to the surface of a carrier to conduct color development; by means of the paint with the dye contained in the microcapsules, the shelf life of the dye can be effectively prolonged, and the dyeing effect of the dye can be effectively ensured.
