Description

technical field [0001] The invention belongs to the technical field of fine chemicals, and in particular relates to a neutral ballpoint pen ink and a preparation method thereof. Background technique [0002] In the prior art, the proportioning of neutral ballpoint pen ink mostly adopts the method of single proportioning of each component, and there are phenomena such as precipitation, leakage, and water bleeding, and the components and viscosity still need to be adjusted. Contents of the invention [0003] The invention uses the compounding technology of various components to solve the technical problems of the ink of the neutral ballpoint pen not drying, not precipitating, not leaking, and being stable for a long time. [0004] The present invention is realized by adopting the following scheme, neutral ball-point pen ink, modified polysiloxane ethers by pigment, solvent, pigment dispersant, thickener, defoamer, preservative, antirust agent, leveling agent, medium The neu...
