Abstract

A kind of correction altering appliance is solid state, and is formulated by opalizer, dispersion tablet-forming and other auxiliary agents.Non-volatile, need not be with special container encloses, so cost is low.It can make different shape, as right cylinder, prism and various bulk, as circular, square, rectangle, rhombus etc., it is several following to rub back and forth on the mistake mark during use, the mistake mark will be covered by one deck white mulch film, and can write again immediately, print, draw.This correction bar can directly use, and also can be contained on the special device or be fixed on various pens to go up use.This correction bar is easy to use than correction fluid, and is effective, is the ideal altering appliance.

Description

Correction bar

The invention belongs to cultural goods.The coated and the rewriting of mistake marks such as it is mainly used in and writes, draws, typewriting.At present, to various fountain pen inks, the butyrous of water-based ballpoint pen oil of all kinds, and various mistake such as typewriting, mimeograph marks, generally adopt correction fluid (as CN85105635A, CN86107867A, US4654081, J01261473 patent) to carry out rewriting behind the coated.Though these correction fluid performances have nothing in common with each other, a kind of liquid substances of forming by high volatile volatile solvent, film-forming binder and opalizer all.During use, earlier with the correction fluid coated on the mistake mark that will rewrite.Treat solvent evaporates, form a white topped film on paper after, could on this topped film, write or print correct literal or image then.The shortcoming of this correction fluid is: after above correction fluid is coated in the mistake mark, generally need to wait for tens of seconds so several minutes clock times after, solvent could volatilize fully.In addition, owing to contain a large amount of high volatile volatile solvents in the correction fluid, so the splendid attire correction fluid must adopt special device (as CN86105473, the US4812071 patent).This has just increased the fringe cost that correction fluid is produced.

In order to overcome the above-mentioned shortcoming of correction fluid, the present invention has provided a kind of solvent-free solid altering rod.This correction bar is made up of opalizer, dispersion tablet-forming and a little auxiliary.Because the absence of liquid solvent exists, it is a solid-state rhoptry (slender cylinder, elongated square body, elongated ribs cylinder, elongated gengon and other shape etc.).During use, should solid-state rhoptry on the mistake mark, rub back and forth several down, the mistake mark just can be covered in by a white topped film.Do not need to wait for any time of solvent evaporates, just can on topped film, write again, print, draw or duplicate immediately.This correction bar can be directly be held with hand and misses mark and alter, and also it can be fixed on a special device (as pen shaped arrangement etc.) and go up and use.Even it directly can also be fixed on and variously write, on the ruling pen, make and write, alter double-purpose pen.

The opalizer that the present invention is used can be polar or nonpolar white pigment, also can be white weighting agent.As TiO ₂, ZnO, lithopone, white carbon black, atlapulgite, zinc sulphide, leaded zinc, stibium trioxide, hydrated magnesium silicate, CaSO ₄, CaCO ₃, MgCO ₃Deng.These white pigments and weighting agent mainly play mistake mark covering effect.They can use separately, also can two or more mix use.Its consumption generally account for whole correction bar heavy 30～95%.

The dispersion tablet-forming that the present invention adopts, its effect is that opalizer is scatter, simultaneously can also these flours are fixed-type.When the mistake mark was altered, it can constitute topped film on paper with opalizer.This topped film not only will have opacifying property preferably to the mistake mark, but also needs certain rigidity and intensity, and high toughness is arranged, and with paper stronger bonding force is arranged.In order to satisfy above-mentioned requirements, dispersion tablet-forming of the present invention has adopted wax or other waxy solid.As paraffin, Microcrystalline Wax, babassu hair fat, polyethylene, white soap flakes, polypropylene glycol, modified rosin, hydrogenated castor oil, polyvinyl acetate (PVA), vinyl acetate-ethylene copolymer, polyvinyl ether, hard ester acid, hard acid ester salt, hard ester acid esters etc., these dispersion tablet-formings can use separately, also can two or more mix use.Its consumption generally accounts for 10～80% of opalizer consumption.

In addition, according to the specific requirement of using, also adopted some auxiliary agents to improve the over-all properties of correction bar among the present invention.For example, in order to improve the adsorptivity of topped film, can add a small amount of atlapulgite, white carbon black, wilkinite etc. to writing pigment of all kinds.In order to improve water-base ink and oily ink wetting property, added low quantity of surfactant among the present invention to topped film.It is hydrophilic that this tensio-active agent has an end, and the other end is hydrophobic molecular structure.In addition, also can add small amount of plasticizer, anti-aging agent, increase the over-all properties that other subsidiary material such as hard agent improve the solid altering rod.

The embodiment of the invention one:

(1) carnauba wax 20(weight percent)

(2) Microcrystalline Wax 16

(3) polyethylene 2

(4) the alkyl phenyl Soxylat A 25-7 5

(5) zinc sulphide 45

（6）CaSO ₄12

First with component (1), (2), (3), (4) are heat fused together, is 0.1～10 μ m (5) with granularity then, and (6) add together, carry out forming processes after thorough mixing is even.Forming processing method has two kinds: a kind ofly the mixture for preparing is poured in the previously prepd mould while hot into the cooled and solidified moulding; The 2nd, with mixture elder generation cooling curing, grind into fine powder, put into compression moulding in the pressing mold then.

Embodiment two:

(1) polyoxyethylene glycol 28(weight percent)

(2) lanolin 10

(3) polyoxyethylene oleate 5

（4）TiO ₂50

(5) white carbon black 7

First with component (1), (2), (3) are heat fused together, adds (4) again, and (5) stir and can carry out forming processes.

These invention materials are extensive, and preparation is simple, and cost is low, and is easy to use, is best altering appliance.Also adjustable simultaneously opalizer and add and join pigment and make the charge bar that is coated with of all kinds.
