Titanium dioxide nano ink

Abstract

The invention relates to a titanium dioxide nano ink which is prepared from the following raw materials in parts by weight: 0.5-2 parts of Al powder with the average particle size of 100nm, 3-5 parts of TiO2 powder with the average particle size of 500nm, 25-30 parts of pigment, 32-40 parts of polyamide resin, 13-17 parts of alkyd resin, 2-5 parts of 6# varnish and 0.1-0.5 part of polyalkyl ethylene glycol. 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...
