Description
Technical field
The present invention relates to auxiliary agent of a kind of Neutral writing ink and preparation method thereof, relate to Neutral writing ink water-emulsifiable moisturizing lubricant and preparation method particularly.
Background technology
Neutral writing ink refers to that the apparent viscosity of ink is between oily ink (1000-2000mPas) and water-base ink (≤20mPas), based on pigment or dyestuff (black, red, blueness) for tinting material, what the oilness of the existing oily ink of ink had again a water-base ink writes happy property, simultaneously compared with traditional dye ink, there is excellent fast light, water-fast, resistance to gentle chemical stability, ink marks convergence is strong, can do persistence, meet dossier requirement.Gel ink pen is the novel kind in ballpoint pen series products, compares with aqueous ballpoint pen with traditional oiliness ballpoint pen, has fluent writing, spry and light comfortable, the advantage such as writing is clear, good, the water-fast sun-proof of color and luster sense, long preservative period of feel.
Neutral writing ink is primarily of stability mill base, thickening material, solvent and moisturizing lubricant, pH adjusting agent, sanitas, the water-based system of the functional agent compositions such as rust-preventive agent, the thixotropic agent that Neutral writing ink adds realizes having different viscosity when difference writes state, when for writing, ink maintains higher viscosity, prevent ink from flowing out from nib or flowing backwards, write at the beginning and drive ball to rotate, velocity of shear is accelerated, ink viscosity reduces rapidly, ink in oil pipe is under the effect of barometric point and self gravitation, from oil pipe through connecting the mesopore and aperture that flow into ball seat body, and then flow on the ball of written front end, because the frictional force effect of writing pressure and ball and writing surface makes ball rotate, and the ink sticking to ball surface just adheres to above writing surface and forms writing by ball again that rotate, thus realize writing process.
Neutral writing ink writing quality is the most also the index the most effectively passing judgment on Neutral writing ink quality, and monolateral, the phenomenon such as broken string, pit that occur in writing process, all because Neutral writing ink changes at lubrication, thixotroping, performance of keeping humidity and causes ball and written excessive friction, excellent gel ink pen product is under guarantee has the prerequisite of good distribution performance, excellent moisturizing lubricity should be had, ensure the fluency of gel ink pen at whole writing process and interval writing process.Therefore study Neutral writing ink with adding auxiliary agent to the quality improving Neutral writing ink, guarantee Neutral writing ink long-term stability uses has important social effect.
Current Neutral writing ink moisturizing lubricating auxiliary agent mainly adopts low volatility polyvalent alcohol as glycerol, ethylene glycol and has certain oily lubricant, it often adopts the method for separately adding, add respectively preparing in Neutral writing ink process, coordinate other auxiliary agents to allocate Neutral writing ink.Therefore often there is Neutral writing ink wildcard poor, can not mate between various auxiliary agent, therefore occur that moisturizing and lubrication regulate and control respectively when development of new Neutral writing ink, but because Neutral writing ink moisturizing and lubricating auxiliary agent influence each other, Neutral writing ink stabilising system may be destroyed, Neutral writing ink product is gone bad, affects Neutral writing ink product development.
In prior art, Neutral writing ink is the water-based system primarily of functional agent compositions such as stability mill base, thickening material, solvent and moisturizing lubricant, pH adjusting agent, sanitas, rust-preventive agent.The moisturizing lubricant adopted generally adopts low volatility polyvalent alcohol as glycerol, ethylene glycol and the cooperation with certain oily lubricant, it often adopts the method for separately adding, add respectively preparing in Neutral writing ink process, coordinate other auxiliary agents to allocate Neutral writing ink.
And of the present invention both there is moisture absorbability and moisture retentivity, the water-emulsifiable moisturizing lubricant again with the Neutral writing ink functional agent of emulsification lubricity can realize the object of Neutral writing ink moisturizing and lubricity coordinated regulation, and the multi-functional regulation and control of Neutral writing ink are realized under low interpolation auxiliary agent, avoid each Self-controlled of Neutral writing ink, the shortcoming of matching difference.
