Abstract
The ink for writing in board and capable of being hydrolyzed includes the following components: pH indicator, alkali, 1, 2-propylene glycol, glycerine, ethanol and deionized water and is prepared through dissolving and polymerization. It may be filled into thick board-writing pen for writing in teacher's board, office board, etc. and filled into thin pen for writing draught and writing projecting sheets. It has the features of high stability, fluent writing, no adhesion to pen tip, easy erasing with wet cloth and no dust pollution.
Description
The present invention relates to the writing on the blackboard material, the present invention relates to the free of contamination ink for writing on blackboard of hydrolyzable specifically.
For a long time, teaching board uses chalk, writing on the blackboard and dust from flying when erasing the board, pollution classroom.Japanese Patent (flat 1-19708), (clear 64-4552) disclose notes plate ink composition, (clear 62-9149) discloses notes plate marking ink, and all kinds of blank pen of domestic and international current trend, people have been familiar with such ink can write on plate face smooth, that do not absorb water, can wipe with blackboard eraser and do not have dust from flying, but such ink blank pen exists serious disadvantage: after wiping, can cause dirty plate by residual look slag on plate face and blackboard eraser; Open the cap for brush, nib is exposed in the air dry and hard easily; It depends on the smooth plate face that does not absorb water can wiping, and smooth plate is used for the school instruction plate then can be reflective, and the student does not see the font at reflective position.
The objective of the invention is to overcome the deficiency in the prior art products, avoid the limitation of chalk and blank pen, provide a kind of energy wet rubbing pollution-free non-dusting writing on the blackboard material for teaching board, office account, exercise plate.With wetting rag wiping, person's handwriting wink is that hydrolysis disappears the not residual look slag of plate face and rag after the writing on the blackboard; Nib is exposed to and is difficult for dry and hardly in the air, writes in optic panel and dull surface writing on the blackboard and all can wipe not dirty plate.
The present invention is achieved by following technical proposals.
The present invention has redness, orange, red-purple, purple, blue look, yellow, green and secondary color and secondary color, is with the hydrolysis ink for writing on blackboard writing on the blackboard pen of packing into during use, writes on clipboard.

Blending process: at normal temperatures each component is dropped into the container polymerization successively, stirred 30 minutes, it is fully dissolved, leave standstill after 3 hours standby.
After ink made, in its writing on the blackboard pen of packing into, its color, fluent writing and erasability were observed in writing on the blackboard on light face and dull surface clipboard; With wetting rag wiping, observe its wiping effect, look slag residual condition; The writing on the blackboard pen is opened the cap for brush expose nib, under normal temperature laboratory, placed 24 hours, observe anti-time and the stability of ink done of nib.
Compare experiment with the blank pen
One. experiment purpose:
1. comparison colours slag residual condition
2. relatively open cap for brush nib and reveal the anti-dried time in the air of putting
3. relatively wipe away situation at optic panel, dull surface blackboard eraser
Two. material is prepared:
1. one in hydrolysis writing on the blackboard red ink writing on the blackboard pen (getting embodiment 1 ink)
2. one in Japanese zebra board redness (middle word) blank pen
3.600 * 800mm light face is write blank, dull surface is write each two of blanks
4. whiteboard eraser is one
5. one of wetting towel
Three. room temp: 20 ℃
Four. operation steps:
1. be 10 of 80 * 80mm Chinese characters with blank pen and hydrolysis ink writing on the blackboard pen writing on the blackboard specification on two light face clipboards and two dull surface clipboards respectively.
2. the word of writing with whiteboard eraser wiping blank pen; The word of writing with wetting towel wiping hydrolysis ink writing on the blackboard pen.Comparing result is as follows:
A. the light colourless plate that writes of blank pen and whiteboard eraser are all residual an ink look slag; Water
The wetting towel of separating light colourless plate that ink writing on the blackboard pen writes and Wiper plate face is equal
Do not find the look slag.
B. the dirty plate of the dull surface blank that writes of blank pen is serious, and hydrolysis ink writing on the blackboard pen is write
The dull surface blank of word does not have dirty plate phenomenon.
3. blank pen and hydrolysis ink writing on the blackboard pen are opened the cap for brush simultaneously, allow nib be placed in the air after 6 hours, use blank pen and the writing on the blackboard on clipboard of hydrolysis ink writing on the blackboard pen respectively.Comparing result is as follows: the dry and hard word of can not writing of blank pen nib; Hydrolysis ink writing on the blackboard pen still can normally be write.
Through the use of embodiment being observed and being shown with contrast experiment's report that the blank pen carries out: the present invention writes smoothness, steady quality; No matter on optic panel or dull surface plate, write, all can not stay stains with wetting rag wiped clean, not residual look slag; Open nib, the anti-dried time is longer, is fit to do school instruction writing on the blackboard apparatus.
