Description

Aqueous writing liquid of anti-ink type and preparation method thereof
Technical field
The present invention relates to a kind of writing liquid and preparation method thereof, more particularly to a kind of aqueous writing liquid of anti-black type and its Preparation method.
Background technology
Calligraphy creation, not simple writing behavior, the general performance of consciousness consciousness and handwriting skills.It is The calligraphic factors such as exaggeration of the technique of writing, the method for the use of ink and water, the art of composition, type posture are naturally combined together, due " the pen and ink feelings of calligraphy are generated Interest " is to reach melting visual effect.
The present invention is envisioned for writing liquid:Using water as solvent, there is good writing quality, writing liquid is dipped with writing brush Calligraphy creation is carried out on rice paper, the place that pen and ink pass through needs to leave stable, smooth person's handwriting, in order to very easily declare The various calligraphy work drafts for having upright stone tablet to open up inversion effect are created on paper.
Realize that aforementioned imagination, the present invention need to solve following at least three technical problem:First, writing liquid has certain Viscosity and good filming performance, a certain amount of writing liquid can be effectively adsorbed when certain viscosity guarantee is dipped with writing brush, protect The continuity of calligraphy creation is demonstrate,proved, good filming performance ensures that the trace of calligraphy creation is uniform and smooth, improves the product that upright stone tablet opens up reversion Matter;Secondly, writing liquid will have certain permeance property and solidifiability, permeance property to ensure that the trace of calligraphy creation can be with a surname Paper firmly combines, and solidifiability ensures to form stable trace form after forming a film in calligraphy production process, does not drop down liquid, avoids printing Interference between mark;Finally, it is necessary to have good water repellency after writing liquid film forming is dry, surface forms stable hydrophobic Film surface, keep away from moisture pollution, grows bacterium.
For above three technical problem, the not systematic writing liquid for solving the technical problem, leads in the prior art When the writing liquid of the prior art being caused to be used for calligraphy creation, there are more defect or deficiencies, influence calligraphy creation quality, the present invention It aims to solve the problem that this technical problem, aqueous writing liquid of a kind of anti-black type and preparation method thereof is provided.
Invention content
It is an object of the invention to solve the deficiencies in the prior art, a kind of aqueous writing liquid of anti-black type and its preparation side are provided Method.There is the writing liquid certain viscosity and good filming performance, certain viscosity guarantee can effectively be inhaled when being dipped with writing brush Attached a certain amount of writing liquid ensures that the continuity of calligraphy creation, good filming performance ensure the trace uniform light of calligraphy creation It is sliding, improve the quality that upright stone tablet opens up reversion;Secondly, writing liquid of the invention will have certain permeance property and solidifiability, infiltration The trace of performance guarantee calligraphy creation can firmly be combined with rice paper, and solidifiability ensures to be formed after forming a film in calligraphy production process Stable trace form, does not drop down liquid, avoids the interference between trace;In addition, after writing liquid film forming is dry, it is necessary to have good Water repellency, surface energy form stable hydrophobic film surface, and keep away from moisture pollution, grow bacterium.Writing liquid based on the present invention The calligraphy work of creation can preserve for a long time, be repeatedly used for upright stone tablet and open up.
Anti- ink type writing liquid definition:Refer on rice paper in a manner of according to prior art ink (writing liquid) is used into Row calligraphy creation, but transparent or translucent membranaceous of calligraphy creation trace, have water repellency, and will not cover rice paper from A kind of writing liquid of right color and texture.
The technical solution adopted by the present invention to solve the technical problems is:
A kind of aqueous writing liquid of anti-black type, the writing liquid are made of A agent and B agent;A agent and B agent separately encapsulate storage, make The agent of used time A and B agent are with mass ratio 1:The ratio mixing of (3-4), which is mixed thoroughly, obtains aqueous writing liquid;
The A agent, which is prepared from the following ingredients in percentage by, to be process:
