Ink lubricants refer to materials that can reduce viscosity or viscosity when added to inks, reduce paper fluff and powder removal, and improve the uniformity of ink distribution. The lubricants used in traditional ink production will more or less produce some pollution, which is not suitable for the needs of today’s market.
CN201610693395.7 provides an environment-friendly lubricant for printing ink with good use effect and simple processing. The following technical solutions are adopted to realize: an environmentally friendly lubricant for printing ink, which is made from the following components in parts by weight: 40-60 parts of methacrylic acid, 5-10 parts of emulsifier, 4-8 parts of Baifeng wax, cinnamon 2-3 parts of aldehyde diethyl acetal, 2-3 parts of defoamer, 6-10 parts of zein, 0.4-0.6 part of cowhide powder, 0.1-0.2 part of paeonol, 0.4-0.6 part of Sophora flavescens gel, Alanine 0.4-0.6 parts, dihydroxyacetone 3-5 parts, nano bamboo charcoal powder 1-3 parts.
The preparation method is as follows: stirring methacrylic acid and an emulsifier, adding Baifeng wax, heating until the Baifeng wax is dissolved, then adding zein, stirring and mixing for 0.5 hours, then adding cowhide powder, paeonol and nano bamboo charcoal powder, heating to 70 -80°C, react for 2 hours, neutralize to pH 7, add cinnamaldehyde diethyl acetal, antifoaming agent, Sophora flavescens gel, alanine and dihydroxyacetone while stirring, and finally start rapid stirring (1440r/ min) to obtain a milky product for production use.
The production process of the invention is simple, and by adding components such as zein, white peak wax, nano-bamboo charcoal powder, etc., the product has excellent lubricating performance and good fusion degree. The beneficial effects of the present invention are as follows: the present invention uses zein for the production of environmentally friendly lubricants for printing inks, which is the first in China;
