Abstract
The invention discloses a water-based ink and a special decoloring agent thereof, and the mixing proportion of the water-based ink is as follows: 2-4g of active dye, 1-2g of polymer, 3-5ml of glycerol, 0.01-0.02g of sodium dodecyl sulfate, 1-2ml of ethanol, 2-3g of cinnamic acid and 100ml of water. The decoloring agent consists of a reducing agent, an antioxidant and a dispersant. The ink has the advantages of bright color, good water solubility and easy degradation, can use the special decoloring agent for carrying out decoloring on written words and is simultaneously conductive to decoloring, recycling and reutilization of waste paper.
Description
Technical field
The present invention relates to writing ink, specifically is a kind of water-base ink and special decoloring agent thereof of easy decolouring.
Background technology
Along with the raising of people's environmental protection consciousness, people also changing, had both required ink to have certain look firmness to the requirement of ink, required again easily writing to be removed when needs decolour.
Existing ink has tannic acid swage blue-black ink, type of dye ink and pigment ink, contain red, ethereal blue, blue-black, colour pattern such as green, brown, black, but the selected colorant of present ink product all is difficult to decolouring.Chinese patent CN87102550A discloses a kind of water solution ink and CN1109484A discloses water-soluble black ink and manufacture method thereof, all select for use substantive dyestuff as the mass-tone material, this class dyestuff poorly water-soluble, the degraded difficulty, be difficult for decolouring during the handwriting mistake and revise also difficult decolouring when waste paper is recycled.
Summary of the invention
The purpose of this invention is to provide a kind of water-base ink, this ink lovely luster, good water solubility, easily degraded can use special-purpose discoloring agent that handwriting is decoloured, and also helps the decolouring and the recycling of waste paper simultaneously.
Another object of the present invention provides a kind of special decoloring agent of above-mentioned water-base ink.
A kind of water-base ink provided by the invention, the set of dispense ratio is: easily the reactive dyestuffs 2～4 of degradation and decolorization restrain, high molecular polymer 1～2 gram, 3～5 milliliters of glycerine, sodium lauryl sulphate 0.01～0.02 gram, 1～2 milliliter of ethanol, styracin 2～3 grams, 100 milliliters in water.
The reactive dyestuffs of described easy degradation and decolorization can be among reactive brilliant bule B-RV, Reactive blue B-GD, reactive dark blue B-2GLN, reactive black B-ED, reactive black BES, reactive black KN-B, active yellow 3 R S, reactive red DS and the reactive violet B-5RV one or both or multiple.
Described high molecular polymer can be one or both in Sudan Gum-arabic, gelatin, shellac and the polyvinyl alcohol, plays function of stabilizer in ink.
Described glycerine can spent glycol etc. has certain viscosity and the higher organism of boiling point to substitute, and plays moisture-keeping function in ink.
Described sodium lauryl sulphate can use Sodium dodecylbenzene sulfonate, Triton-100 or Tween-60 plasma type or nonionic surface active agent to substitute, and plays solubilising and stabilization in ink.
Described ethanol can substitute with the alcohol compound of low surface tension, plays the defoamer effect in ink.
Described styracin both can play flavouring agent, also played the effect of sanitas.
The preparation method of water-base ink provided by the invention is: high molecular polymer is dissolved in the hot water stirring and dissolving; The powdered reactive dyestuffs are joined in the high molecular polymer aqueous solution mix; Add glycerine, sodium lauryl sulphate, ethanol and styracin again, stir, place 24 hours after-filtration, packing.
The special decoloring agent of above-mentioned water-base ink provided by the invention, the set of dispense ratio is: reductive agent 1.5～3 grams, 4～6 milliliters of glycerine, p methoxy phenol 0.0001～0.0004 gram, sodium lauryl sulphate 0.01～0.02 gram, sodium hydroxide 0.2～0.3 gram, 100 milliliters in water.
Described reductive agent can be vat powder and/or S-WAT.
The preparation method of water-base ink special decoloring agent provided by the invention: reductive agent is soluble in water, add p methoxy phenol, sodium lauryl sulphate, sodium hydroxide and glycerine, mix packing.
Water-base ink provided by the invention is applicable to pen, ruling pen and signature pen etc.Special decoloring agent provided by the invention is applicable to the decolouring to above-mentioned water-base ink, can realize decolouring as long as spread upon above-mentioned ink writing place.
Water-base ink provided by the invention and special decoloring agent thereof have following advantage:
1. the reactive dyestuffs of the easy degradation and decolorization selected for use of the present invention have good water solubility, do not precipitate characteristics bright in colour, in the ink formulation process, add auxiliary agents such as solubility promoter, tensio-active agent, anti-quick dry agent, made the ink fluent writing, do not stopped up nib, lovely luster, rate of drying is suitable.
2. water-base ink of the present invention can be realized the modification of handwriting and the deinking of waste paper with special decoloring agent degradation and decolorization leniently.
3. the selected easy degrading active dye of the present invention is cheap, nontoxic, does not have " three cause ".
4. special decoloring agent of the present invention is nontoxic.
