Description
Technical field
The invention belongs to teaching aid technical field, and in particular to a kind of to improve the gel ink pen of fluent writing degree.
Background technology
Increasing student is write using gel ink pen now, and they can but write out the effect of fountain pen word without frequent blotting
Really, therefore liked by students very much.At present, known gel ink pen is made up of the cap for brush, a body and the part of pen core three, but this
Usually there is stifled pen in writing and can not write or slack phenomenon in pen, and general gel ink pen is write slack reason and led to
It is often that pen core ink flow is deteriorated, caused by ink supply is not smooth.
The content of the invention
The purpose of the present invention is to improve the gel ink pen of fluent writing degree there is provided a kind of for existing issue.
The present invention is achieved by the following technical solutions：It is a kind of to improve the gel ink pen of fluent writing degree, including a body,
Spring, air admission hole, push pedal, connector, nib, ink-feeding hole, ink, sealing wax, pen point casing, described passes through between body and nib
Connector is connected, and the pen point casing set is enclosed in nib, and the fill ink is in a body, filled with sealing at the top of the ink
Push pedal is provided with the top of wax, the sealing wax, the push pedal upper end is connected with spring, and the spring other end is fixedly attached to pen
At the top of body, air admission hole is additionally provided with the top of described body, described body bottom left is provided with ink-feeding hole, and the air admission hole is normal
Open state, the ink-feeding hole is normally off, and the ink-feeding hole seals by elastic rubber material, the elastic rubber material by
TPE elastomer material is molded in injection molding.
Further, the ink is made up of following component by weight：It is carbon black 12, dispersant 35, thickener 12, pure
Water purification 60, levelling agent 0.3, hydroxymethyl cellulose 6, ultra-fine starch 2, false indigo root extract 0.2, paper mulberry juice 2.
Further, the dispersant is aqueous urethane dispersants.
Further, the thickener is polyvinyl alcohol.
Further, the levelling agent is the hydroxy acryl acid resin of fluorine richness.
Further, ultra-fine starch preparation method is：Cornstarch and water are configured to the solution that concentration of substrate is 25wt%
Afterwards, the laurate formation reaction solution of starch quality 10% is added, is handled 2 hours under the conditions of temperature is 72 DEG C, then be ground 2
Hour, filter, dry, cross after 800 mesh, obtain ultra-fine starch.
Further, the false indigo root extract preparation method is：False indigo root is cut into slices, is first 3 times with its quality
Temperature is 65 DEG C of clear water immersion 40min, is then taken out, then is dried, and pulverizes, crosses 80 mesh, then add its 4 times of quality
Clear water, is heated to 75 DEG C, is incubated 2 hours, filtering, by filter residue use mass concentration for 78% ethanol solution refluxing extraction 3 times,
1.5 hours every time, filtering reclaimed ethanol, obtains filtrate, filtrate is carried out into rotary evaporation, dries, and obtained the extraction of false indigo root
Thing.
Further, paper mulberry juice preparation method is：Feed with paper-mulberry leaf and water are pressed 1：After the mixing of 4 mass ratios, it is beaten,
Then 2 hours are stood at 40 DEG C, filtering obtains filtrate, filtrate is carried out to be concentrated into 1st/20th of original volume, needed for producing
Paper mulberry juice.
The present invention has advantages below compared with prior art：Gel ink pen prepared by the present invention can write stream on paper
Freely, a variety of paper writings are suitable for, beauty of line is write on a variety of paper and sees, color is goth black, can be with black carbon pen ink
Aqueous phase matches in excellence or beauty, and can be good at combining by using ultra-fine starch, aqueous urethane dispersants and carbon black, while again and false indigo
Root extract is mutually promoted, and ultimately forms a suspension stabilising system for adhering to one another, mutually promoting, and is had for carbon black particle
There is fabulous suspending stabilized effect, can improve and increase ink viscosities, product stability is kept, while in can also impart to
Property the preferable mobility of board pen ink and thixotropy, improve shear shinning index, pass through and certain mass is added in a stature material
Magnesia, can greatly improve the thermal conductivity of a body so that when hand is held a body and write, heat on hand can be faster
Be delivered in ink, after ink heat absorption, mobility more, writing be it is more smooth, by a body bottom left set into
Ink hole, can be filled ink when ink runs low, it is to avoid existing neutral pen ink can only abandon after using up and cause wave
Take the phenomenon with environmental pollution.
Brief description of the drawings
Fig. 1 is a kind of structural representation for the gel ink pen that can improve fluent writing degree.
Embodiment
The present invention is further described below in conjunction with the accompanying drawings.
As shown in fig. 1, it is a kind of to improve the gel ink pen of fluent writing degree, including a body 1, spring 2, air admission hole 3, push pedal
4th, connector 5, nib 6, ink-feeding hole 7, ink 8, sealing wax 9,6 sets of nib, connector 5 is passed through between described body 1 and nib 6
It is connected, written 6 sets of sets are enclosed in nib 6, and the ink 8 is filled in a body 1, the top of ink 8 is filled with sealing
Wax 9, the top of sealing wax 9 is provided with push pedal 4, and the upper end of push pedal 4 is connected with spring 2, and the other end of spring 2, which is fixed, to be connected
The top of a body 1 is connected to, the described top of body 1 is additionally provided with air admission hole 3, and the described bottom left of body 1 is provided with ink-feeding hole 7, institute
Air admission hole 3 is stated for normally open, the ink-feeding hole 7 is normally off, and the ink-feeding hole 7 is sealed by elastic rubber material, described
Elastic rubber material is molded by TPE elastomer material in injection molding.
