Abstract
The invention provides black writing liquid suitable for being written on a matt board and an erasing agent. The writing liquid comprises the components of acid No.3 green, acid fuchsin, a dispersing agent, a stabilizer, a plasticizer, sodium citrate and distilled water. The erasing agent comprises the components of a reducing agent, a complexing agent, a dispersing agent, an antioxidant, a solidifying agent, sodium carbonate and distilled water. The black writing liquid suitable for being written on the matt board and the erasing agent have simple formulas, easily obtained raw materials and low costs. The writing liquid is prepared by an anaglyphic principle, has the advantages of no toxicity, no odor, no generation of precipitates after the writing liquid is stored for a long time and the like, is smooth to write, is particularly suitable for being written on the teaching matt board. The erasing agent can be used for rapidly erasing writing written by the writing liquid, and no writing liquid shadow exists.
Description
Technical field
The present invention relates to ink, specifically belong to a kind of and be suitable for the black writing liquid of on inferior tabula rasa, writing and wipe agent.
Background technology
The blackboard chalk that traditional writing on the blackboard demonstration is used has produced serious dust pollution when teaching, the harm teachers and students' is healthy.In order to address this problem, the scientific research personnel has developed the substitute products of multiple chalk, and wherein the blank pen is write liquid, and advantages such as having fluent writing, easily wipe, be dustless is generally accepted by people, and drops into a large amount of the use.Yet blank is easily reflective, diminishes student eyesight, influences teaching efficiency.Though and inferior tabula rasa has overcome the easily reflective defective of blank, when using writing liquid for white board to write on inferior tabula rasa, these are write, and liquid is most easily to infiltrate in the inferior tabula rasa, is difficult for wiping, even if use special erasing liquor, also still leaves the ink shade.
Summary of the invention
The purpose of this invention is to provide and a kind ofly be suitable for the black writing liquid of writing and wipe agent on inferior tabula rasa, this to write liquid formula simple, and cost is lower, and nontoxic, non-stimulated smell to human body and environmentally friendly, is not put for a long time and can be produced precipitation; The agent of wiping that it is supporting is easy to handwriting is wiped, and writes liquid at the writing of writing on inferior tabula rasa, wipes Shi Buhui and the liquid shade occurs writing with wiping agent.
A kind of black writing liquid of on inferior tabula rasa, writing of being suitable for provided by the invention, its components based on weight percentage:
Acid No. 3 green 0.2～0.6%
C.I. 42685 1.0～1.5%
Dispersion agent 0.01～0.05%
Stablizer 0.08～0.2%
Softening agent 5～10%
Trisodium Citrate 0.05～0.10%
Distilled water surplus.
Described dispersion agent is selected from a kind of among fatty alcohol-polyoxyethylene ether AEO-8, fatty alcohol-polyoxyethylene ether AEO-9, fatty alcohol-polyoxyethylene ether AEO-10 and the fatty alcohol-polyoxyethylene ether AEO-15; Described stablizer is a water soluble starch; Described softening agent is glycerol or glycol ether.
Write the preparation of liquid: stablizer is placed distilled water, be heated to boiling under stirring, it is dissolved fully, be cooled to room temperature, add C.I. 42685, acid No. 3 green, Trisodium Citrates, dispersion agent and softening agent then, stir, place after 24 hours, filter and promptly can be made into black writing liquid.
The liquid of writing of the present invention prepares according to colorant complementary principle.Present black when certain colorant and another kind of coloring material for mixing, these two kinds of colorants complementary color material each other then, the colorant complementary color is black after mixing.Magenta and green be complementary color each other, so C.I. 42685 and greenly be mixed into black with certain proportion acid No. 3.
Black writing liquid provided by the invention and above-mentioned is matching used wipes agent, its component and content by weight percentage:
Reductive agent 0.08～0.15%
Shaping agent 0.5～1.0%
Complexing agent 0.01～0.02%
Antioxidant 0.01～0.05%
Dispersion agent 0.1～0.3%
Yellow soda ash 0.1～0.5%
Distilled water surplus.
Wherein said reductive agent is vat powder or S-WAT; Described shaping agent is five water Sulfothiorine; Described complexing agent is EDTA or CyDTA; Described antioxidant is a p methoxy phenol; Described dispersion agent is selected from a kind of in Sodium dodecylbenzene sulfonate, sodium stearate, sodium laurylsulfonate and the sodium lauryl sulphate.
Wipe the preparation method of agent: reductive agent is dissolved in the distilled water, adds shaping agent, antioxidant, complexing agent, dispersion agent and yellow soda ash, stir, promptly.
Compared with the prior art, the liquid of writing of the present invention is to be prepared from according to colorant complementary principle, the easy-to-use chemical reduction method of liquid of writing of the simple black pigment preparation of the black writing liquor ratio that complementary colorant forms fades, promptly wipe agent with special use of the present invention and wipe and fade, and thisly write liquid also to have a prescription simple, cost is lower, dustless nontoxic, non-stimulated smell, do not put and can produce precipitation for a long time, fluent writing, lettering pen be remarkable advantage such as liquid feeding use repeatedly, is suitable for writing use on inferior tabula rasa.The wipe agent supporting with writing liquid is to utilize the chemical reduction principle formulated, and it is easy to decolour and wipe writing the liquid writing, writes liquid at the writing of writing on inferior tabula rasa, wipes Shi Buhui and the liquid shade occurs writing with wiping agent.
