A kind of fluid pressure type free ink pen environmental protection ink and preparation method thereofTechnical field
The present invention relates to a kind of environmental protection ink and preparation method thereof, more specifically say that one do not stick with paste plate, easily wiping, environmental protection ink of good stability and preparation method thereof, belongs to Chemicals preparing technical field.
Background technology
For a long time, chalk ash pollution is larger, numerous users endure dust injury to the fullest extent, in order to change this phenomenon, writing on blackboard ink is the new door product that ink industry is developed in recent years, there is the characteristics such as dustless, easy wiping, supporting with Special writing pen, easy to carry, erasing out handwriting within a certain period of time, continue to write and depending on reading and do not affect, there is the writing function of traditional ink, easy-to-write and erasable, no dust pollution, be widely used in the occasion such as office and academic exchange, meeting, become gradually a new focus of chemical research.
The writing on blackboard special-purpose ink of marketing is to be mainly made up of oily solution and staining agent in the market, and this ink also has difficult wiping, easily scumming, and inequality out of ink, writes shortcoming not smooth, poisonous, not environmental protection.In order to overcome this shortcoming, free ink pen environmental protection ink is come out one after another, and be scattered in ink system and make it painted equably, but common writing on blackboard ink pigment particles is large with pigment particles, dispersion effect is poor, can not reach desirable writing effect, if its particle is diminished, along with diminishing of size of particles, specific surface area will increase greatly, Van der Waals force between particle will become greatly, very easily produce cohesion between the particle of emblem, thereby cause producing layering, precipitation iso-metamorphism phenomenon in storage process.General Technology and equipment are difficult to make pigment particles in ink system to keep good dispersion stabilization.Moreover, keeping low viscous stablizing is again an important indicator, because environmental protection ink is directly to add in fluid pressure type free ink pen part, so, size requirements to pigment particles is higher: viscosity is slightly bigger than normal, will affect amount out of ink, causes and writes not smooth or broken string, viscosity is too low, there will be again ink leak phenomenon.
In production process, elongated along with the increase of grinding rate and time, it is large that the viscosity of ink system will become, so keeping low viscosity and being controlled at is the another important technology difficult point of fluid pressure type ink for aqueous pen more among a small circle., producing the environment-friendly water-based board pen ink of desirable high-quality, is the important technology problem that is worth research.
Chinese patent document CN101962500A discloses the ink that environment-friendly type erasable changes, nontoxic pollution-free, but product is single, and the product dispersiveness of preparation is bad, and Heating temperature is too high in process of production, environmental protection not.The invention provides a kind of fluid pressure type aqueous, environmental protective board pen ink and manufacture method thereof, adopt " green technology " and " formula of science ", be intended to effectively solve the difficult wiping of conventional panels book ink, easily scumming, inequality out of ink, writes problem not smooth, poisonous, not environmental protection.By the particle diameter to cheekbone material, viscosity, storage layering and write the research of the technical problems such as infiltration, develop the environmental protection ink of good stability, be applicable to special fluid pressure type free ink pen.
Summary of the invention
The object of this invention is to provide a kind of fluid pressure type free ink pen environmental protection ink and preparation method thereof, not only technique is simple, and the product color of preparation is bright-coloured, out of ink evenly, fluent writing, does not stick with paste plate, easily wiping, steady quality, energy-conserving and environment-protective.
In order to address the above problem, the technical solution adopted in the present invention is:

Described pigment is the one in white, yellow, red, blue four base colors of pigment.
Described resin is water-borne acrylic resin.
Described dispersion agent is polymkeric substance macromolecule dispersing agent.
Described wetting Agent for Printing Inks is polyoxyethylene glycol or glycol ethers.
Described solvent is ethanol.
A kind of fluid pressure type free ink pen environmental protection ink, is made up of the component of following weight part:
Pigment 6.5%, water-borne acrylic resin 5.50%, ethanol 88.5%, polymkeric substance macromolecule dispersing agent 3.5%, polyoxyethylene glycol 6%.
A preparation method for fluid pressure type free ink pen environmental protection ink, comprises the steps:
First solvent is added in pre-dispersed pot, under stirring, add dispersion agent, resin, wetting Agent for Printing Inks by formula rate successively, straight
To being all uniformly dissolved, finally add pigment, after being fully uniformly mixed, then carry out micro-grinding 2 ~ 8 hours, make the diameter of granules of pigments reach specific standard size, stop grinding discharging.
Grain diameter after described granules of pigments grinds is D=300 ~ 700 nanometer.
the invention has the beneficial effects as follows:
(1) adopt micro-grinding technique, make granules of pigments median size reach 300 ~ 700 nanometers, and adopt polymkeric substance macromolecule dispersing agent, can be dissolved in fast in solvent, significantly reduce the viscosity of dispersion system in particulate process of lapping, improve pigment particles wetting property, shorten face section particle milling time, improve the dispersion stabilization in the long-time storage process of pigment dispersion system.
(2) use unique scientific formula, make ink there is good dispersion stabilization and lower viscosity, conscientiously meet fluid pressure type free ink pen nib pore size, prevent that ink leak, the problem such as dry and hard from occurring; Ink lovely luster, even, fluent writing out of ink, do not stick with paste plate, easily wiping, do not form dust; It is neutral that pH is, less to user's skin corrodibility.
(3) the present invention, under normal temperature or severe environment, all can normally write; In lower 1 year of bottled ink normal temperature, there is not layering, separation, precipitation iso-metamorphism phenomenon, can long-term storage, steady quality; Preparation technology is simple, and cost is low, energy-conserving and environment-protective.
