Description
Technical field
The present invention relates to a kind of environment-friendly blackboard writing liquid and preparation method thereof, more specifically say that one do not stick with paste plate, easily wiping, writing liquid 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.
Take a broad view of the research and development course of writing on blackboard ink, since last century 50, the sixties, passed through so far following developmental stage: (1) can not step section, early stage white board marker is write and is write rear extremely difficult wiping; Its primary solvent is ketone that toxicity is larger, ester, benzene class and composition thereof; (2) the erasable stage, becoming slightly erasable, but smell stimulates very much through development, and not moisturizing, and its primary solvent is acetate esters and alcohols and its derivative; (3) stage easy to use, erasability has greatly improvement, and it is gentle that smell shows slightly, and has certain performance of keeping humidity, and stays and still have erasability after the plate certain period, and its primary solvent is aliphatic alcohols and its derivative that toxicity is lower.
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.From the angle of Sustainable development, along with the progress in epoch, the breakthrough of science and technology, people will propose the requirement of higher more rationality to utensil used in everyday.The research and development track of writing on blackboard ink will inevitably stride into the new stage: the environmental protection hommization stage, and water-soluble, and do not harm environment and the mankind.
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.
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 writing on blackboard ink 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 CN102786843A discloses a kind of white board marker environment-friendly writing ink, is made up environment-protecting asepsis of vegetable pigment, emulsifying agent, Viscotrol C, protruding Attapulgite, ethanol and the heating of deionized water composition stirring and dissolving; Chinese patent document CN10264989A also discloses a kind of preparation method of environment-friendly type aqueous white ink, but these product dispersion effects are desirable not enough.The invention provides a kind of environment-friendly blackboard writing liquid 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 environment-friendly blackboard writing pen.
Summary of the invention
The object of this invention is to provide a kind of environment-friendly blackboard writing liquid 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.
