Abstract

The invention discloses a preparation method of phase-change ink, belonging to the technical field of ink preparation. The preparation method comprises the steps of preparing phase-change microcapsules, preparing the phase-change ink and the like. The phase-change microcapsule ink prepared by using the method is a new material which takes a high-molecular polymer as a shell and contains a phase-change material inside; the phase-change ink has excellent phase-change latent heat, and the temperature control effect of a microcapsule can be brought into full play; and the phase-change ink can release or absorb heat in a surrounding environment to achieve the effects of recycling energy and saving energy of a product, so the function of the ink is broadened, and the ink can play more roles in various fields.

Description

technical field [0001] The invention relates to the technical field of ink preparation, in particular to a preparation method of phase change ink. Background technique [0002] There are many types of inks, but most inks mainly play the role of transmitting information and beautifying patterns, while microcapsule inks not only have the role of information transmission, but also have specific functions. For example, thermal expansion (foaming) ink, its function is to realize the three-dimensional sense and velvet touch, but the three-dimensional control effect of this ink is still closely related to information transmission and patterning. [0003] At present, phase change microcapsules embedded with phase change materials have attracted more and more attention as a new green material with high efficiency and energy saving. The function of phase change microcapsules is mainly reflected in the ability to absorb or release heat as the ambient temperature changes to maintain th...
