Abstract

The invention discloses a plastic product mold internal decorative thermal transfer printing ink and a preparation method thereof. The ink comprises the following components by the mass percentage: 8-20% of polyester resin, 8-20% of acrylic resin, 0.5-1.5% of rosin modified phenolic resin, 5-10% of a curing agent, 5-15% of a pigment, 40-70% of a solvent, 0.5-1% of a defoaming agent, 0.5-1% of a levelling agent, 0.5-1% of a wetting dispersant, and 0.5-1% of an anti-blocking agent. The preparation method comprises the steps: according to the proportion, mixing the pigment, 50% of the resin, the wetting dispersant and 50% of the solvent, grinding and dispersing for 1 h with a grinding machine to obtain a color paste, then adding the remaining 50% of the resin, the levelling agent, the defoaming agent, the anti-blocking agent, 50% of the solvent, mixing and stirring uniformly to obtain an ink A component, taking the curing agent as an ink B component, respectively sub-packing the ink A component and the ink B component, and then mixing uniformly when in use. The product has the properties of good 300-DEG C high-temperature temperature change, flexibility, surface hardness, impact resistance, cohesiveness, water resistance, acid and alkali resistance and the like.

Description

technical field [0001] The invention relates to the technical field of inks, in particular to a thermal transfer printing ink used for in-mold decoration of plastic products and a preparation method thereof. Background technique [0002] In-mold decoration thermal transfer technology is a method of color printing. After printing ink and coating adhesive on a transparent film coated with varnish, it is then put into a plastic molding mold for plastic injection molding to produce Plastic products with colorful and beautiful effects on the surface, a relatively simple, environmentally friendly, fast, efficient and relatively low-cost new technology. The surface of this type of plastic product is a hardened transparent film, the middle is an ink layer for printing patterns, and the back is an injection molding material layer. The product can prevent the surface from being scratched and rubbed, and can maintain bright colors for a long time without fading. [0003] Since the in...
