Study Of The Technology Of Preparing Pigmental Gel-Ink

China is the largest producer of Gel ink ball-point pen, with its output in recent years has been ranking first in the world, but this should be a relatively neutral pen manufacturing is the core material - Gel-ink still rely mainly on imports. This situation has hampered the sustainable development of China's Pen industry directly, and then it's must to produce the Gel ink in our country.First, this paper ink on the definition, the characteristics and the technical background of Gel ink, point out that Gel ink technology developed by the major technical challenges can be summarized into four areas, namely the paint is stably dispersed in the water-based system, the Thixotropy, the lubricant and the process of production. Second, the author offer a method that it includes high-speed centrifuge experiment heating experiments on a large number of experiments and it can fleetly estimate the stability of the Gel ink.As Gel ink system complex, the dispersion stability of the pigments have high requirements, based on the double electrode layer effect of anionic dispersant on the carbon particles and the space effect of water-soluble polymers on the carbon particles The water-soluble polymers and anionic dispersant have a synergistic effect, so the market's leading dispersants and polymer products were screened, it can been achieved to produce the stability carbon paste.Author researches three different thixotropy formed, including its thixotropic index and the stability of color paste, and offer to use the thickener and the dispersants synchronously to achieve the thixotropy.On the lubricant problem, we inspected the system of viscosity, thixotropic value, and different lubricants and paint a different size of the impact on the lubricant. Based on this, we offer the means from the technical formulation and preparation of two aspects to achieve the lubricant.Finally, according to the technology Formula of the Gel ink, establish the corresponding production process and identified various production process.In short, the large number of papers in the development of experimental resolved on the basis of the development of the Gel ink several technical problems and to determine the scale of the production process conditions, with prospects of the industry. Including the issue of the technological projects "the new production technologies of Gel ink "through the identification of scientific and technological achievements in SSTD, its overall reach the international advanced level.
