Abstract

The invention relates to an ink, and in particular, relates to a heat insulation ink reflecting infrared rays and a preparation method thereof. The heat-insulating ink reflecting the infrared rays isprepared from the following raw materials by the mass fraction: 10-20% of a color paste, 50-70% of pure water-borne polyurethane resin, 10-20% of an auxiliary agent, and the balance purified water. Apigment contained in the color paste is copper chromite black. The preparation method includes the steps: (1) preparation of the color paste: preparing the color paste by grinding with a horizontal nano sand mill, to make the fineness of the color paste reach 5 [mu]m or less; (2) preparation of the ink: mixing ink raw materials, then dispersing evenly through a high-speed disperser, controlling the viscosity at 5000-7000, and finally fully grinding by a hydraulic three-roller grinder. The prepared ink is environmentally friendly pure water-borne ink; the heat-insulating ink has good heat resistance, light resistance, chemical resistance, and good coloring strength, and can reflect the infrared rays, so as to achieve the effect of heat insulation and cooling; and the ink can be used in thefields of shoes, clothes and outdoor umbrellas and tents.

Description

technical field [0001] The invention relates to an ink, in particular to an infrared-reflecting heat-insulating ink and a preparation method thereof. Background technique [0002] Ink (ink, printing ink) is an important material for printing. It expresses patterns and characters on the substrate by printing or inkjet painting. The ink includes main components and auxiliary components, which are composed of binders (resins), pigments, fillers, additives and solvents. It is used for various printing of books, magazines, packaging and decoration, architectural decoration and electronic circuit boards. With the increase of social demand, the variety and output of ink have also expanded and increased accordingly. [0003] At present, many outdoor printing inks are mostly dark-colored inks, and the pigments used in dark-colored inks are usually carbon black, iron oxide black, etc. However, since these pigments absorb light of wavelengths from the ultraviolet region to the far i...
