Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a so-called writing board such as a white board and a color board, and a liquid ink built-in marker written on a non-absorbing surface such as a glass board, an enamel board and a plastic board. Alternatively, the present invention relates to a method of wiping handwriting by a solid drawing material with a wiping tool.

(Prior art) In recent years, instead of conventional blackboards, ink containing a release agent has been incorporated into non-absorbing surfaces such as writing boards, glass boards, enamel boards, and plastic boards, because colorful colors can be obtained. There is an increasing use of writing with a marker or a solid drawing material having a relatively low fixing property.

The handwriting with the above ink or solid drawing material can be easily wiped off by simply rubbing the handwriting with a wiping tool without dissolving the handwriting with an organic solvent at the time of erasing. It has the nature.

(Problems to be Solved by the Invention) However, handwriting made of the ink or the solid drawing material has a surfactant, a wax, a lubricant, a plasticizer, etc. for imparting weak fixability to the handwriting and maintaining the handwriting. There are additives, such as a release agent, that impart releasability to handwriting. Therefore, if the handwriting is rubbed with a wiping tool of the type that wipes the handwriting, even if the colored part of the handwriting is wiped off, the above-mentioned additive remains on the plate surface, and the handwriting oozes at the time of rewriting, or I was sometimes out. Further, depending on the type and amount of the additive, the handwriting may be extended due to abrasion, and it may be difficult to easily wipe the handwriting. An object of the present invention is to provide a method for wiping a handwriting that can easily wipe the handwriting and also has good rewriting.

(Means for Solving the Problems) An object of the present invention is to provide a method for wiping handwriting on a non-absorbing surface, wherein powder is interposed between the handwriting and the wiping tool.

 Hereinafter, the present invention will be described in detail.

The point of the method for wiping handwriting according to the present invention is that powder is interposed between the writing tool and the wiping tool when the handwriting is rubbed on the handwriting. To interpose the powder between the writing tool and the wiping tool, attach the powder prepared separately from the wiping tool onto the handwriting, and then wipe the handwriting with the wiping tool. Although it is good, it is built in the wiping tool, for example, by moving the powder to the wiping surface of the wiping tool by hitting the plate surface with the wiping tool and attaching it to the handwriting, the handwriting is wiped with the wiping tool It is preferable to rub and wipe off, because handling is easier.

As a wiper, a body made of wood or synthetic resin, such as a conventionally known eraser for writing boards, a cloth, felt, nonwoven fabric made of synthetic resin, synthetic paper, etc. Or with a flocked hair on the surface or a mohair-type wiping part attached.
The invention is not limited to such specialized wiping tools. For example, paper such as tissue paper or the like may be used.

The powder is used for easily wiping the handwriting and preventing the above-mentioned additives from remaining. There is no particular limitation on the use, and the powder is appropriately selected according to the material of the writing surface and the type of the handwriting. it can. To be more specific, as the inorganic powder, kaolin clay, calcined clay, kaolin, kaolinite, halosite, metahalosite, zeolite, sericite, mica, sodium montmorillonite, sodium bentonite, calcium bentonite, wood Seto clay, frog eye clay, pottery stone, allophane, fluorite, talc, chalk, hot asbestos, silica sand, zircon sand, ultrafine silica, white carbon, diatomaceous earth, calcined diatomaceous earth, fluxed diatomaceous earth, alumina, active Alumina, silicon carbide, dolomite powder, strontium carbonate, barium carbonate, barium titanate, europium oxide, yttrium oxide, magnesium oxide, aluminum silicate, ultrafine titanium oxide, titanium oxide, zinc oxide, calcium carbonate,

Furthermore, AS-10 in which the surface of carbohydrates such as starch and calcium carbonate is coated with inorganic or organic substances
0, Surface treatment such as AS-100S, AS-100E (manufactured by Nikka Co., Ltd.) or eposter S, eposter S12, eposter M30, eposter MS (manufactured by Nippon Shokubai Kagaku Kogyo Co., Ltd.) in which amino resin is coated with an inorganic substance. Powder or a processed powder obtained by compounding a plurality of types of powder by applying a mechanical impact force may be used. As the shape of the powder, various shapes such as an amorphous shape, a spherical shape, and a needle shape can be used, but a spherical shape is particularly preferable, and a particle size of 10 to 50 μm is preferable.

In order to incorporate powder into the wiping tool, if a writing board eraser is used as the wiping tool, a method such as placing a layer of powder between the main body and the wiping part is adopted, and tissue paper is used. When using a cloth, for example, tissue paper,
For example, a method is used in which a cloth or the like is formed into a form such as valence and powder is used instead of the core material.

(Action) In the present invention, the powder is interposed between the handwriting and the wiping tool to wipe off the handwriting, so that the powder takes in the additive in the handwriting, and the handwriting is easily wiped off. Does not remain.
