Abstract

The invention relates to the technical field of preparation of waterborne ink and in particular relates to a preparation method of antistatic waterproof type waterborne ink. According to the preparation method provided by the invention, the antistatic waterproof type waterborne ink is prepared by taking modified self-made emulsion as a matrix and silver-loading graphite powder and a self-made mixture as a reinforcing agent, and adding titanium white, absolute ethyl alcohol, dimethicone and the like; firstly, modified acrylic resin is effectively filled charged into the waterborne ink; when thecontent of graphite powder is increased, conductive channels formed between conductive particles are increased, so that the antistatic performance of the waterborne ink is easy to improve; tin hydroxide gel formed by reaction of stannous chloride and the graphite powder is adsorbed on to the surface of the graphite powder to form micro-particles, so that the antistatic performance of the waterborne ink is improved; sodium silicate and silicon dioxide react and are subjected to condensation polymerization to form silicon dioxide hydrate; then a dense silicon dioxide hydrate film-coating layeris gradually formed and tightly covers the matrix, so that the water resistance of the waterborne ink is improved; the waterborne ink has a wide application prospect.

Description

technical field [0001] The invention relates to the technical field of water-based ink preparation, in particular to a method for preparing an antistatic water-resistant water-based ink. Background technique [0002] With the development of social culture, science and technology, and economy, the printing industry is developing at an unprecedented speed, and ink is the largest source of pollution in the printing industry. The world's ink production has reached 3.5 million tons, and the annual volatile organic compound (VOC) pollution caused by ink The discharge amount reaches more than 500,000 tons, which seriously pollutes the atmospheric environment and directly endangers human health. With the continuous improvement of people's awareness of environmental protection, green environmental protection has become the development theme of the 21st century. Therefore, the research, development and application of green packaging and printing materials with less harm, less polluti...
