Abstract
The ink for writing on non-absorptive smooth surface is made of TiO2 or light calcium carbonate, polyvinyl alcohol or polyvinyl butyral, alcohol polyoxyvinethene or sodium dodecylbenzenesulfonate, dibutyl phthalate or dioctyl phthalate or propanetriester, glycol and water. Special fountain pen with this ink can replace chalk. It features no poison, no odouring, smooth writing, clear trace and easy erasing.
Description
The present invention relates to a kind of ink, especially a kind of liquid of writing on the nonabsorbable smooth surface of writing.
Writing liquid for teaching board is a kind of chalk surrogate, and the lettering pen that its injection is special-purpose can replace chalk to be used for teaching, has advantages such as writing smoothly, easily wipe, be dustless.This class is write liquid and is mainly contained two kinds, and a kind of is to be medium with the organic solvent, as the disclosed liquid of writing among the CN 1078730A; Another kind then is medium with water, as the disclosed liquid of writing among the CN 1054994A.It is low and harmless because of its cost with water to be that the water-based of medium is write liquid, is suitable for imparting knowledge to students going up and uses.Yet existing water-based is write the less stable of emulsion in the liquid, puts easy layering for a long time, easily stops up nib when writing; Write the back writing and easily shrink, produce disconnected mark, cause writing unclear; And freeze-proof is relatively poor, is not suitable for using at cold district.
The object of the invention provides a kind ofly writes that the back writing does not shrink, constantly the water-based of mark is write liquid, and its nontoxic, non-stimulated smell, but long storage and fluently writing under different weathers are easily wiped.
The present invention is formulated by mineral dye, membrane-forming agent, emulsifying agent, softening agent, frostproofer and water, and its component (by weight percentage) is:
Titanium dioxide or light calcium carbonate 10～40%
Polyvinyl alcohol or polyvinyl butyral acetal 1～10%
Fatty alcohol-polyoxyethylene ether or Sodium dodecylbenzene sulfonate 0.3～3%
Dibutyl phthalate or dioctyl phthalate (DOP) or glycerol 1～10%
Ethylene glycol 0.2～2%
Water 50～70%
Mineral dye is selected titanium dioxide or light calcium carbonate for use; Membrane-forming agent is selected polyvinyl alcohol or polyvinyl butyral acetal for use; Emulsifying agent can be selected fatty alcohol-polyoxyethylene ether or Sodium dodecylbenzene sulfonate for use; Softening agent can be selected dibutyl phthalate or dioctyl phthalate (DOP) or glycerol for use; Frostproofer is an ethylene glycol.After mentioned component is mixed in proportion, write liquid through grinding promptly to can be made into.
The present invention selects for use titanium dioxide and light calcium carbonate to make pigment, can guarantee the clear of writing, helps again reducing cost; Add membrane-forming agent, make the pigment of writing in the liquid, when wiping, do not produce dust writing back formation film rapidly; Softening agent can improve film performance, makes it the quality softness and is easy to wipe; Add emulsifying agent and make that to write liquid emulsion stable, written handwriting is clear, smooth; Add ethylene glycol and make frostproofer, write liquid and still can use below 0 ℃.
The present invention writes that the back writing does not shrink, continuous mark, and writing is still clear constant after 30 days, easily wipes and dustless.The erasability of writing and time are irrelevant.
Be embodiments of the invention below, described ratio all is weight percentage:
Embodiment 1:
Titanium dioxide 20%
Dibutyl phthalate 3%
Polyvinyl alcohol 5%
Ethylene glycol 1%
Fatty alcohol-polyoxyethylene ether 3%
Glycerol 3%
Water 65%
Embodiment 2:
Titanium dioxide 10%
Light calcium carbonate 20%
Dioctyl phthalate (DOP) 2%
Polyvinyl alcohol 5%
Polyvinyl butyral acetal 2%
Sodium dodecylbenzene sulfonate 1%
Glycerol 1%
Ethylene glycol 1.5%
Water 57.5%
Claims (1)
1, a kind ofly write liquid, it is characterized in that the weight percent content of component is by what mineral dye, membrane-forming agent, emulsifying agent, softening agent, frostproofer and water preparation face became:
Titanium dioxide or light calcium carbonate 10～40%
Polyvinyl alcohol or polyvinyl butyral acetal 1～10%
Fatty alcohol-polyoxyethylene ether or Sodium dodecylbenzene sulfonate 0.3～3%
Dibutyl phthalate or dioctyl phthalate (DOP) or glycerol 1～10%
