Problems solved by technology

[0002] The production of pencils has a long history, and it has many advantages, such as simple manufacture, convenient wiping of written fonts, etc., but there are also many disadvantages. The first is that a pencil sharpener or other auxiliary tools are needed in use, which is troublesome to use. The first is that the carbon rod is worn out during use, and the pencil needs to be sharpened frequently, which is a waste of time. The third is that higher skills are required when sharpening the pencil, which may easily cause the carbon rod to break. The fourth is that the pencil tip lacks a protective device, which is easy to cause The tip of the pen is broken. Fifth, the pencil is too short to continue to be used and has to be discarded at the end of use. Sixth, the shell cannot be reused, which wastes more resources. Seventh, it pollutes the environment to a certain extent. The shape and its convenience and flexibility are very popular among people, and now it has become an indispensable part of writing stationery, but it also has a major defect: the written font cannot be wiped off, although people think of many remedial methods such as inventing and altering. liquid, but still cannot make up for its deficiency

Embodiment 1

[0017] Embodiment 1: described ink is the making of black ink:

[0018] 71.0 parts of mixed solvent oil, 6.0 parts of artificial latex (Cariflex IR700), 3.8 parts of low M cis 1.4-polyisoamyl derivative carrier, 1.4 parts of modified natural rubber, 5.2 parts of high-pigment carbon black, 1.8 parts of light blue pulp , 8 parts of molybdenum disulfide, 0.8 parts of organotin compound, and 2.0 parts of polyethylene vinyl acetate were sequentially added to a conical heating vessel with a stirring jacket, heated to 138 ° C, and continuously stirred at high speed for 9 hours, then stopped adding Stir gently, cool to room temperature, filter, then grind to the required particle size with a grinder, and finally filter.

[0019] The aforementioned latex (Cariflex IR700) is commercially available from Shell Chemical Company, USA.

Embodiment 2

[0020] Embodiment 2: described ink is that the component that blue color ink adopts is:

[0021] 71 parts of mixed solvent oil, 2 parts of artificial latex (EssoButylLate×100), 7 parts of modified natural rubber, 0.7 part of linear wood rosin, 0.8 part of terpene resin, 7 parts of phthalocyanine blue, 1.5 parts of permanent violet RL, 1 1 part of white carbon black, 6 parts of boron nitride, 2.5 parts of polyethylene vinyl acetate, and 0.5 parts of dioctyl phthalate (DOP) were sequentially added to a conical heating vessel with a stirring jacket and heated to 138 °C , continuously stirred at high speed for 9 hours, then stopped heating and stirring, cooled to room temperature, filtered, and then ground to the required particle size with a grinder, and finally filtered.

[0022] The above-mentioned latex (EssoButylLate × 100) can be purchased at Esso Chemical Company in the United States

Embodiment 3

[0023] Embodiment 3: described printing ink is that the component that redness adopts is:

[0024] 69.7 parts of mixed solvent oil, 3 parts of modified natural rubber, 6 parts of low M cis-1.4-polyisoamyl derivative carrier, 1 part of rosin ester, 7 parts of sunfast red BBN, 3.5 parts of permanent red F4R, 6 parts of nitrogen Add boron chloride, 1.6 talcum powder, 0.2 aluminum stearate, and 2 polyethylene vinyl acetate into a conical heating vessel with a stirring jacket in turn, heat to 138°C, stir continuously at high speed for 9 hours, and then stop heating and stirring, cooled to room temperature, filtered, and then ground to the required particle size with a grinder, and finally filtered.

Abstract

An ink is proportionally prepared from solvent oil, the resin or modified rubber or artificial latex or rubber derivative or their mixture, coloring agent, filler and additive through proportional mixing, heating while high-speed stirring, cooling, filter, grinding and filter. It is suitable for ball-point pen or other pens. Its advantages are no damage and pollution, easy erasing, and not decoloring.
