Calcium carbonate nano ink

Abstract

The invention relates to a calcium carbonate nano ink which is prepared from the following raw materials in parts by weight: 37-45 parts of pigment, 13-26 parts of CaCO3 with the average particle size of 100nm, 10-20 parts of maleic anhydride rosin, 21-29 parts of epoxy resin, 7-10 parts of acrylic resin, 3-7 parts of isopropanol and 1-2 parts of calcium stearate. The ink has the advantages of favorable stability, low pigment consumption, high covering power, full color, clear printed image and long service life, and is suitable for industrial production.

Description

technical field [0001] The invention relates to the technical field of ink, in particular to a nanometer ink. Background technique [0002] Ordinary ink is a uniform mixture composed of pigments (including colored pigments and fillers), linking materials, mineral oil, additives, etc. It can be printed and dried on the printed object. It has a color and a certain fluidity. Siamese. The composition of nano-ink is basically the same as that of ordinary ink. The biggest difference between them is the size of the pigment particles. The pigment particle size of ordinary ink is micron level, while the pigment particle size of nano ink is nano level, the size difference between the two is about 1000 times, and the fineness of the ink made in this way has been greatly improved. The fineness and purity of ink have a great influence on the quality of printed matter. The smaller the pigment particles, the higher the fineness of the ink, and the clearer, fuller and more powerful the d...
