Problems solved by technology

However, if you only rely on compressed air to push the ink, when the ink in the pen core decreases and the space of the compressed air increases, the thrust of the ink decreases, and the continuity of the ink is poor, and it is easy to break the ink during the writing process. Great inconvenience to users

Abstract

The invention relates to a high viscoelastic resin special for space pen ink, a preparation method and an ink using the special resin. The high viscoelastic resin special for space pen ink includes a space network polymer and a water-based acrylic resin. The water-based acrylic resin The resin is formed by the reaction of acrylic resin and organic amine. The spatial network polymer is polymerized by linear hydroxyl acrylic resin and isocyanate cross-linking agent containing isocyanate groups. The water-based acrylic resin is dispersed in the spatial network polymer. The preparation method of the present invention includes four steps of synthesizing hydroxyl acrylic resin, preparing spatial network polymer, preparing high viscoelastic resin and neutralizing the resin to make it water-based. The resin prepared by the invention has good water solubility and alcohol solubility, and has high viscoelasticity. The ink made by using the resin also has high viscoelasticity.

Description

technical field [0001] The invention relates to the technical field of resins, more specifically, it relates to a special high-viscosity elastic resin for space pen ink, a preparation method and an ink using the resin. Background technique [0002] A space pen refers to a pen that can be used normally in a gravity-free state. In addition to being suitable for spaceflight, a space pen with excellent performance can also be used in harsh environments such as mountaineering, diving, adventure tourism, and polar expeditions. Now general pens and ballpoint pens rely on the gravity of the liquid droplet to complete the ink discharge from the nib, so they cannot be used in a non-gravity state. Existing space pens are generally filled with compressed gas at the top of the core of the pen. When using the space pen to write, ink is pushed to the nib by gas pressure. However, if you only rely on compressed air to push the ink, when the ink in the pen core decreases and the space of t...
