Abstract
The water soluble black ink consists of sun-fast black 6-20% (wt.), sodiumhydroxide 0.4-2%, brightening agent arabic gum 2-5%, glycerine 1.25-5%, stabilizer dimethyl sulphoxide 2.12-5.3%, anti-precipitant S.K.T. compound 0.54-3.26% and water 59.04-87.69%. It is suitable for pen, drawing pen and ball pen.
Description
The invention belongs to writing ink.
Patent gazette the 5th volume discloses a kind of water-soluble black ink CN1036977A that is made up of direct black dyes, water-miscible organic solvent dimethyl sulfoxide (DMSO), blackening agent Resorcinol, water repellent agent polyvinyl butyral, solubilizing agent glucose, water No. 45; There is following defective in above-mentioned patent application: 1, ink is easily to permeating all around and downwards; 2, the poorly water-soluble of direct fast black; A phenomenon that stagnates still appears in easy drying and volatilizing when 3, ink is write; 4, in the ink manufacturing processed, need heating, increase manufacturing cost.
The purpose of this invention is to provide a kind of good water solubility, wettability strong, impermeable, do not stagnate pen, non-setting water-soluble black ink, in preparation process, need not heat.
The object of the present invention is achieved like this: a kind of water-soluble black ink, to form by direct black dyes, permeability-reducing admixture, water-miscible organic solvent, anti-settling agent, wetting agent, water, and it also contains sodium hydroxide; The content of water-soluble black ink (weight) is as follows:
Direct fast black G.B 6-20%
Sodium hydroxide 0.4-2%
Sudan Gum-arabic 2-5%
Glycerine 1.25-5%
Dimethyl sulfoxide (DMSO) 2.12-5%
Anti-settling agent S.K.T compound 0.54-3.26%
Water 59.04-87.69%
Its preparation method several steps in the following order carries out: sodium hydroxide is soluble in water, mix; The powdered direct fast black joined in the sodium hydroxide solution mix; Filter the back and add the gum arabic solution stirring; Add dimethyl sulfoxide (DMSO), glycerine and anti-settling agent again, agitation and filtration, packing.
Make in the ink that forms by above-mentioned various materials are mixed, sodium hydroxide is chaotropic agent, and sodium hydroxide is to direct fast black G.B degreasing, emit heat simultaneously, make the water-soluble raising of direct fast black, therefore also do not need to provide in addition thermal source, heating promotes the thorough mixing of several materials to solution; Adopt glycerine to make wetting agent, the water evaporation time is long more than glucose, can not cause the dry pen that stagnates of India ink; After adding Sudan Gum-arabic, make the ink bright in color, be easy to written record and preserve; After adding anti-settling agent S.K.T compound, prevent from effectively to precipitate when ink from leaving standstill; Therefore to have a cost cheap in this invention, and good stability such as does not precipitate at advantage.
Preparation method of the present invention is as follows: powder solid shape sodium hydroxide is dissolved in purifies waste water, stirred 5 to 10 minutes; The powdered direct fast black is joined in the sodium hydroxide solution, stirred 10 to 30 minutes; It is fully dissolved, filter the back and add gum arabic solution, stirred 5 to 10 minutes, add a certain amount of dimethyl sulfoxide (DMSO), glycerine and anti-settling agent again, stirred 10 to 30 minutes, after mixing, leave standstill, filter, pack.
