Problems solved by technology

However, the current pure blue neutral ink is usually pigment-based, and the efficient dispersion and emulsification of the pigment has not been completely solved, resulting in poor product stability, and long-term storage is prone to sedimentation and clogging of the nib. At the same time, the color is dull, highly corrosive,

Abstract

The invention provides a pure blue gel ink, which comprises the following components by weight portion: (a) 2.0 to 7.0 portions of water-soluble blue dye, (b) 0.1 to 0.2 portion of thickening agent, (c) 0.5 to 2.5 portions of acrylic resin, (d) 10.0 to 15.0 portions of humectant, (e) 0.05 to 0.3 portion of antiseptic anti-mildew agent, (f) 0.1 to 0.5 portion of auxiliary agent, and (g) 74.5 to 82.25 portions of water, wherein the total weight of the components (a) to (g) accounts for 95 to 100 percent of the total weight of a composition. The pure blue gel ink has the advantages of good stability and water-fast writing.

Description

technical field [0001] The invention relates to an ink and a manufacturing method thereof, in particular to a pure blue neutral ink and a manufacturing method thereof. Background technique [0002] The gel pen has the characteristics of smooth writing, comfortable hand feel, water resistance, light resistance, and long storage time, so it has become a popular writing tool in the world. As far as my country is concerned, in the mid-1990s, some domestic pen factories began to set foot in the production of gel pens. After more than ten years of hard work, the production and sales of gel pens in my country have now ranked among the top in the world. However, its high-tech neutral ink still relies on imports, mainly from Japan, Germany, the United States and South Korea, so the price has remained high. In order to develop our country from a big pen-making country into a strong pen-making country, many domestic pen factories and research institutes have carried out a lot of explo...
